Cheapest Way To Heat A Room UK (Air Conditioning Is the Hack!)

Posted on 27th November 202528th November 2025 by evergreen

When winter hits in the UK, most of us automatically turn to radiators, fan heaters, or big gas bills! But what if we let you in on a secret… Staying warm doesn’t have to be expensive and if you’re searching for the cheapest way to stay warm in UK winters then Air Conditioning is the secret hack! Yes, the same unit that cools you down in summer can also keep you warm all winter. In this guide, we explain how AC heating works, why it’s so efficient, and how you can stay warm for less.

Why Air Conditioning Is One of the Most Efficient Ways to Stay Warm in Winter?

Most of us still think of air conditioning as “just for summer,” but modern systems are actually powerful heaters too. In fact, they are one of the cheapest ways to heat a UK home, especially as gas and electric prices continue to rise.

Unlike boilers/electric heaters that burn fuel to create heat, air conditioning systems use advanced heat pump technology to move heat from outdoors to indoors. This uses less energy and delivers a much higher heat output for every unit of electricity used.

Looking for a way to stay warm this winter without huge bills? Air conditioning may be your solution. 👉🏼 Get in Touch!

✘ Traditional Heating Systems

Gas Boilers:

COP 0.85–0.95
Meaning: You get less heat than the energy you’ve paid for.

Electric Heaters (Fan heaters, oil radiators, panel heaters):

COP 1.0
Meaning: Every £1 of electricity gives you only £1 of heat.

Storage Heaters:

Can be cheap off-peak, but extremely expensive if used at the wrong time.

✔ Air Conditioning (Heat Pump Systems)

Modern air conditioning systems work as heat pumps, meaning they don’t create heat, they transfer heat from outside to inside.

Efficiency (COP): 3.0 to 4.0
For every 1 kW of electricity consumed, you get 3-4 kW of heating output.
Equivalent to:

Spend £1 → Receive £3–£4 worth of heat

This makes air conditioning one of the most efficient heating options available in the UK.

*COP (Coefficient of Performance) simply tells you how much heat you get for each unit of electricity so a higher COP means lower bills.

Is Air Conditioning Cheaper to Run Than Central Heating?

Short answer: Yes, in most cases air conditioning is significantly the cheaper heating method because it uses far less energy to generate heat. 👉🏼 Get a FREE survey today!

Real world example – Heating a medium sized bedroom for 1 hour:

Gas radiator: ~24p
Electric Heater: ~40-80p
Air Conditioning Heat Pump: ~7-12p

This is why more and more homeowners in Hertfordshire, Essex and London are choosing Air Conditioning.

Why Air Conditioning Heating Works Especially Well in UK Homes

Our homes can get chilly over winter with central heating taking a while to warm up. AC Heat pumps solve can help by:

✔ Heating the room you’re actually in – No need to heat the whole house.

✔ Heats within 60 seconds – Faster than any radiator.

✔ Great for working from home – Keep your office warm without heating unused rooms.

✔ Cleaner, healthier air – Built in filters remove allergens and dust that radiators can’t.

What About Summer? Your AC Does Both!

Unlike boilers (heating only), modern AC systems provide:

Heating
Cooling
Dehumidification
Air filtration
Improved airflow

One investment = year round comfort.

This is why more UK homes are installing AC in winter instead of summer.

FAQ: Heating Your Home With Air Conditioning in UK Winters

Is air conditioning really cheaper to run than central heating?

Yes. Modern air conditioning systems (heat pumps) are often cheaper to run than gas boilers, even though electricity costs more per unit.

Because heat pumps produce 3-4 kW of heat for every 1 kW of electricity used, the true cost per kWh of heat is usually 7p-9p, compared to gas heating at 24p per hour for the same room.

Can air conditioning heat my entire house?

Heat pumps are designed to heat the rooms you use most quickly and efficiently. Many homeowners install AC units in bedrooms, living rooms, loft conversions, home offices and extensions. This gives you targeted warmth without paying to heat the whole house.

Is air conditioning more environmentally friendly than using my boiler?

Absolutely. Heat pumps use renewable heat from the outdoor air and drastically reduce carbon emissions compared with gas boilers. They also future proof your home as the UK moves towards low carbon heating.

How quickly can an air conditioning unit heat a room?

Within 30-60 seconds! Heat pumps warm a room far faster than radiators, which is why they’re ideal for winter mornings, cold bedrooms, quick evening heating or working from home.

Does AC heating dry the air out?

No. Modern heat pumps maintain comfortable humidity levels and actually improve indoor air quality through built in filtration.

Can I use my air conditioner for cooling in summer too?

Yes! all modern heat pumps are dual function. You get heating, cooling, dehumidification, air filtration and more. A great all year round investment.

Do air conditioning units come with long warranties?

Yes. When installed by certified specialists like Evergreen Air Conditioning, premium brands offer up to 10-year manufacturer backed warranties.

Portable Cabin Air Conditioning UK: The Best Options?

Posted on 12th November 202512th November 2025 by evergreen

In this guide, we’ll explore the best Portable Cabin Air Conditioning options in the UK and explain why porta cabins need air conditioning to stay safe, productive, and energy-efficient in every UK season.

Why Do Portable cabins Need Air Conditioning?

Portable cabins in the UK are a practical and cost-effective solution for temporary offices, classrooms, construction sites and more. However keeping them comfortable in summers (or even winters) can be a challenge. Unlike traditional buildings, porta cabins usually have thin walls, limited insulation, and minimal ventilation, which means they heat up quickly in summer and lose warmth just as fast in winter. Therefore porta cabin air conditioning has become essential for maintaining the right temperature and air quality.

Installing a suitable air conditioning system in a portable cabin helps:

Regulate indoor temperature to maintain comfort and productivity
Protect electronic equipment from overheating
Improve air quality and ventilation, reducing dust and humidity often found on building sites
Comply with HSE (Health and Safety Executive) guidance on maintaining a safe and comfortable working environment

Whatever your portable cabin is being used for, a properly fitted AC system ensures a healthy, efficient space all year round.

What Are the Best Types of Air Conditioning for Portable cabins in the UK?

The right air conditioning system for your porta cabin depends on how long the unit will be in use, power availability, and the size of the space. Here are the most effective options:

Portable Air Conditioners

Ideal for short-term projects or temporary site setups
Quick and easy to install, simply plug in and vent through a window or flexible duct
Perfect for construction sites where cabins are frequently moved or replaced
Require minimal setup and can be repositioned as needed

Wall-Mounted Split Systems

Best suited for medium to long-term installations such as project offices or modular classrooms
Comprise an indoor unit and outdoor condenser, connected by refrigerant piping
Offer energy efficiency, quiet operation, and strong cooling performance
Installed quickly with minimal disruption, ideal for tight construction schedules

Cassette or Ceiling-Mounted Units

Excellent for larger or high-traffic cabins, providing even air distribution throughout
Typically installed in modular welfare areas, canteens, or meeting rooms
Compact, modern design that saves wall space

At Evergreen Air Conditioning, we supply and install all three types, offering both temporary and permanent systems depending on your project’s duration and site requirements.

How Can You Set Up Temporary AC Efficiently on Construction Sites?

Efficient setup is key to maintaining comfort and compliance on construction sites. Here’s how to ensure your air conditioning performs at its best:

Choose the right cooling capacity (BTU rating): Oversized or undersized units waste energy. We assess your cabin’s size and recommend the perfect system.
Ensure proper ventilation: Especially for portable units, exhaust hoses should be vented correctly to remove warm air and prevent condensation build up.
Schedule regular servicing: Dust, debris, and construction site particles can quickly clog filters and reduce airflow. Our air conditioning cleaning and maintenance plans ensure your system stays efficient and compliant.
Follow HSE and safety standards: We meet all F-Gas and Health & Safety regulations, ensuring electrical and refrigerant work is fully compliant.

Do I Need Air Conditioning for a Construction Site Cabins?

Yes! Air conditioning isn’t just about comfort; it’s also about compliance and productivity. According to HSE guidance, employers must provide a reasonable working temperature and adequate ventilation in site offices and welfare cabins.

Installing air conditioning helps you:

Stay compliant with HSE workplace comfort standards
Improve staff morale and focus during hot weather
Prevent delays caused by overheated equipment or unsafe working conditions

Whether it’s a construction site office, canteen, or welfare unit, AC is now considered a best practice requirement rather than a luxury.

How much does it cost to run an air conditioner in the UK?

Posted on 10th May 202226th November 2025 by evergreen

Wondering how much it costs to run an air conditioner in the UK? This guide explains average running costs, what affects them, and how to keep your energy bills low.

Air conditioning was once seen as a luxury only the wealthy could afford. However, in recent years, it has become an affordable option for many homeowners.

Advances in technology and design have reduced installation and running costs. As a result, air conditioning has become increasingly popular in the UK. Following several hot summers, demand has reached record levels.

How much does an air conditioner cost to run?

With energy prices on the rise, this is one of the most common questions we receive. Unfortunately, there isn’t a single answer. The cost of running an air conditioner depends on several factors including system size, energy rating, and how long it runs each day. We’ve broken down these key factors in more detail below.

How much power does an air conditioner use?

Power usage varies between manufacturers and system types.

For the most accurate figure, check with our installation engineer or the electrician who provided your power connection.They can confirm the recommended fuse size and maximum energy draw for your unit.

What factors will affect running costs?

The cost of running an air conditioner depends on its type, size, and usage. When we say size, we’re referring to its cooling output, not its physical dimensions. Generally, the longer your system runs, the higher your electricity bills will be.

Modern air conditioners are designed to be energy efficient, but usage still plays a big part. In today’s environmentally conscious world, being mindful of energy use is more important than ever, both for your wallet and the planet.

Insulation…

Most people think of insulation as something that keeps heat in during the winter. But good insulation also does a great job of keeping the summer heat out. If your home is well insulated, your air conditioner won’t need to run as often or work as hard to maintain a comfortable temperature. This helps reduce energy use and lowers your running costs.

So whether you’re cooling your home in summer or heating it in winter, ensuring your property is well insulated is one of the best ways to improve efficiency and save money.

Have regular service and maintenance …

Regular servicing helps your air conditioning system run efficiently and last longer. It can also reduce running costs and help keep your energy bills lower.

Most domestic systems should be serviced once a year, while commercial systems usually need two visits per year. An engineer will carry out a full inspection, spot early signs of wear or faults, and repair or replace parts before they cause bigger issues. This prevents costly breakdowns and ensures your air conditioner performs at its best all year round.

Installation Costs vs Running Costs

It can be tempting to choose the cheapest air conditioner, but this often leads to higher long-term costs. Cheaper systems are usually less efficient and can be more expensive to run. Inverter air conditioners are a smarter investment. They use a variable-speed compressor that adjusts automatically to maintain the ideal temperature. Because they don’t constantly power on and off like older systems, they waste less energy. Although inverter systems cost more to install, they’re far more efficient, reliable, and durable, making them a better long-term choice.

Consider unit size …

Getting the right unit size is key to keeping your running costs low. A unit that’s too small will struggle to heat or cool your space efficiently. On the other hand, an oversized unit will waste energy and be more expensive to run and maintain. Choosing the correct size system ensures optimal performance and efficiency, helping you save money over time.

Take Control of Your Air Conditioning System

Get to know your air conditioner’s energy-saving features. A well controlled system can reduce your running costs and improve efficiency. Take a few minutes to read your user manual and explore the settings available.

Modern air conditioning units often include Wi-Fi connectivity, allowing you to adjust temperatures through a smartphone app or by voice control using Alexa or Google Home. These smart features make it easy to customise your heating and cooling schedule, monitor your energy use, and ensure your system only runs when needed, helping you stay comfortable while saving energy.

Choose the right air conditioner for your needs ….

Selecting the right air conditioning system makes all the difference in comfort and efficiency.

Whether you need cooling for a single room or a complete climate control solution for your entire property, we have a wide range of energy-efficient systems to suit every space and budget. Our expert team can guide you in choosing the perfect unit for your home or business.

Is Air Conditioning Bad For The Environment?

Posted on 29th April 202227th November 2025 by evergreen

Many homeowners worry that installing air conditioning could harm the environment. In reality, modern AC systems, especially heat pumps are one of the most efficient, low-carbon ways to heat and cool your home. In this guide, we explain how air conditioning impacts the environment, how climate change affects all of us, and what you can do to reduce your carbon footprint.

Why is Climate Change Such a Hot Topic?

Climate change is one of the biggest global threats we face today. Without action, we will see more extreme weather, rising sea levels, severe droughts and continued loss of wildlife. Global warming is already impacting how we live, and the effects will only worsen over the next few decades.

Human activity is the main cause of climate change. Every choice we make, from the transport we use to the energy that powers our homes affects the planet. To protect our future, we need to reduce greenhouse gas emissions and move towards more sustainable, low carbon living.

What Can I Do To Help Reduce Global Warming?

Small changes made by millions of people can make a huge difference. Simple actions like reducing plastic use, cycling instead of driving, or eating less meat all help lower emissions.

However, one of the biggest changes you can make is switching to cleaner energy! Around a quarter of all man made greenhouse gas emissions come from burning fossil fuels for heat and electricity. By choosing a low carbon heating system, such as a heat pump, or an air conditioning unit, you reduce your household emissions and save money on energy bills, especially as energy prices continue to increase.

Is Air Conditioning Bad For The Environment?

Modern air conditioners (heat pumps) are highly efficient and low carbon. Although they use electricity, they produce far more heating or cooling output than the electricity they consume. This makes them significantly more efficient than gas boilers or electric radiators.

You can reduce your carbon footprint even further by choosing a supplier that provides 100% renewable electricity.

Modern AC units also use updated refrigerants with much lower environmental impact. Today’s refrigerants work at higher pressures and deliver better performance, which means the system uses less energy overall.

The UK government aims to reach net-zero emissions by 2050, which includes phasing out fossil fuel heating.

Heat pumps and air conditioners will play a major role in the transition to cleaner, greener energy. Right now, the government even offers 0% VAT on installation because they support these systems as a sustainable solution.

Do Air Conditioners Release Harmful Gas?

All air conditioners contain refrigerant, but modern refrigerants are far more environmentally friendly than older gases. Due to strict F-Gas Regulations, manufacturers have invested heavily in safer, more efficient alternatives.

One of the best examples is R32 refrigerant, which has a global warming potential around two-thirds lower than older refrigerants. It is also easier to reuse, recycle and install. This proves that the AC industry is committed to reducing environmental impact.

Do Air Conditioners Release CO2?

No! The units themselves do not emit CO₂. However, they use electricity, and if your electricity comes from fossil fuels, the energy supplier will generate CO₂ during production.

You can avoid this by switching to a renewable energy provider, which completely removes this indirect CO₂ impact. The UK must legally generate 100% renewable electricity by 2050, so this will improve every year.

Do I Need To Have My Air Conditioning Serviced?

Yes. A yearly service by a qualified engineer keeps your system running efficiently. This reduces energy use, cuts your running costs and lowers your environmental impact. Regular servicing also helps prevent refrigerant leaks and keeps performance consistent. We offer maintenance and service plans tailored to you!

Which Air Conditioners Are The Most Environmentally Friendly?

When choosing an eco-friendly air conditioner, look for:

R32 refrigerant
A+++ or A++ energy ratings (especially on smaller units)
Smart sensors that switch off when the room is empty
WiFi control, allowing precise temperature management

FAQs - Air Conditioning & the Environment

Are modern air conditioners environmentally friendly?

Yes. Modern air conditioners use low-impact refrigerants like R32 and are far more energy-efficient than older systems. When combined with renewable electricity, they become a low-carbon cooling and heating solution.

Do air conditioners increase my carbon footprint?

Only indirectly. AC units use electricity, so your environmental impact depends on your energy supplier! Switching to a renewable energy provider drastically reduces your carbon footprint. AC units use less energy than your central heating but regulate the temperature in your home much faster.

What refrigerant is best for the environment?

R32 refrigerant is currently the most environmentally friendly option widely used in UK domestic AC systems. It has a much lower global warming potential compared to older gases and is easier to recycle.

Is a heat pump better for the environment than a gas boiler?

Yes. Heat pumps use far less energy and produce significantly fewer carbon emissions than gas boilers. They are also part of the UK’s long-term plan to reach net-zero emissions by 2050.

How often should I service my air conditioner?

Once a year. Annual maintenance keeps the system efficient, reduces energy use, lowers running costs and ensures refrigerant levels remain safe and leak-free.

Are air conditioners expensive to run?

Modern AC units are very energy efficient. Many homeowners find that heat pumps cost less to run than electric heaters or older gas boilers, especially in well insulated homes.

Can air conditioning help reduce my energy bills?

Yes. Because heat pumps produce more heating or cooling energy than the electricity they consume, they can be cheaper to run compared to traditional systems.

Will installing air conditioning add value to my home?

In many areas, yes! As the UK moves towards low-carbon heating, homes with efficient air conditioning/heat pump systems are becoming more desirable and future proof.

Is air conditioning suitable for older UK homes?

Absolutely. Modern systems are compact, quiet and designed for both new builds and older properties. A specialist installer can recommend the best system based on your insulation, room sizes and needs.

0% VAT for Domestic Air Conditioning Systems

Posted on 29th March 20229th June 2025 by evergreen

Chancellor scraps the VAT on heat pumps…

Exciting news emerges for the AC industry as the 2022 Chancellor’s Spring Statement reveals that homeowners who have energy saving building solutions installed in their homes, such as heat pumps, no longer need to pay VAT.

The changes will take effect from April 2022 and will last five years, providing benefit to both homeowners and contractors in the industry.

If you’re looking for home air conditioning, 0% VAT means there has never been a better time.

Predicted increase in demand…

With the current hot topic of rising energy prices, and the government’s zero emissions goal for 2050, we predict that this will boost the market for energy saving, low carbon heat pumps that not only offer a viable, cost effective and sustainable heating solution during the winter months but can also provide welcome relief from the soaring summer temperatures.

With low running costs and high efficiency, the purchase of an AC system to heat and cool your home, is a decision that is easy on your pocket and on the planet, as we all have a part to play in helping to reach the UK’s climate goals.

The rules on installation on energy saving materials…

The rules of qualifying installations have also been simplified considerably alongside the cuts. In the past, systems used to cool were not eligible for the reduced rate. Now, as long as the system can provide heating in addition to cooling to a domestic property, it is eligible for the scheme.

Prior to April 1st 2022, there was a ‘60% test’ in place which has also been abolished. The ‘60% test’ was implemented by HMRC. This would limit the reduced VAT rate where materials exceeded 60% of the total cost charged to the customer.

Resellers of air conditioning units without the installation service must continue to charge 20% VAT.

The scheme does not apply to portable systems and is set to run from April 2022 to March 2027.

You can read the full notice on the government website here.

Are air conditioning systems classed as heat pumps? …

Most air conditioning systems are considered as heat pumps due to the fact they can provide heating and cooling. Otherwise known as air-to-air heat pumps. Modern day gasses (R410a and more recently R22) have higher pressure and produce more heating power. Modern day technology means that air conditioning heating is now extremely efficient. Read more on how air conditioning works here.

What are ESMs?

ESMs is simply an abbreviation of Energy Saving Materials. Energy saving materials are products and/or systems that use as little electricity, gas, etc. as possible, or help to reduce their use. They lower the impact we have on our environment, which is why the government is providing incentives for us to install them. ESM’s come in different forms but they can be divided into groups as follows:

Controls for central heating and hot water systems
Draught stripping
Insulation
Solar panels
Ground source heat pumps
Air source heat pumps

The government has recently introduced a zero rate for installation on the following ESMs…

Controls for central heating and hot water systems
Draught stripping
Insulation
Solar panels

Why has 0% VAT for air conditioning installation been introduced?

The government has plans to drastically reduce domestic carbon emissions and this is all part of the wider net zero objective that we have already discussed. They have scrapped the previous complicated VAT rate scheme on certain specified energy saving materials, replaced it with a zero rate of VAT.

It is anticipated this money saving move will incentivise homeowners to take-up ESMs such as heat pumps (and this includes most air conditioners).

Can I get a grant to install air conditioning?

The government has introduced grants to encourage homeowners to install low carbon heating systems such as heat pumps, including most air conditioners, through the Boiler Upgrade Scheme (BUS). This scheme will “help property owners overcome the upfront cost of low carbon heating technologies”. This only applies to installations after April 2022.

To find out if your installation meets the criteria for a BUS grant there is more information on the GOV.UK website.

Do I need planning permission for air conditioning?

Posted on 15th March 20229th June 2025 by evergreen

One of the most common questions asked by consumers when considering air con for their home is if they need planning permission.

In this article we will walk you through the current legislation and regulations to ensure you are compliant when you have your air conditioner installed.

What is planning permission?

Simply put, applying for Planning Permission, is putting in a request to the authorities to see whether you can legally carry out building works, or alterations, to your property.

Once your application has been reviewed by your local planning authority It will be granted (perhaps subject to certain conditions) or refused.

It is essential that you do not carry out any works until you have secured planning permission, or have established that you do not need it, otherwise you could be served with an Enforcement Notice with is a legal order to undo any changes you have made to your property.

Do you need planning permission to install domestic air conditioning?

In most instances, as long as you adhere to the permitted development regulations, it is not a requirement in domestic settings unless you are installing in one of the following areas …

If you have any doubt about your legal position with regards to installing an air conditioning system to your property we would advise you to contact your Local Planning Authority.

In most instances, as long as you adhere to the permitted development regulations, it is not a requirement in domestic settings unless you are installing in one of the following areas …

If you have any doubt about your legal position with regards to installing an air conditioning system to your property we would advise you to contact your Local Planning Authority.

What about air conditioning for Listed Buildings or in Conservation Areas?

A Listed Building will need Listed Building Consent and a property within a Conservation Area will need planning permission before being able to the install an air conditioner. This is a legal requirement.

There are often restrictions in place when it comes to alterations that are likely to affect the character or fabric of a Listed Building, or spoil the appearance of a Conservation Area, and this can mean in some cases that a traditional external condenser unit cannot be installed.

It is worth bearing in mind that planning requests can take anywhere from 6-14 weeks (in some cases longer) to be processed, so be sure to get your application in during the colder months if you want your air conditioner to be up and running in the Summer.

Your specialist installer would be happy to discuss different options with you so that your application is likely to be looked upon favourably by your local authority.

What are the air conditioning installation guidelines I should be aware of?

There are some important regulations that need to be adhered to when you are deciding where to install your air conditioner. As we mentioned earlier, failure to comply with guidelines and regulations could lead to you being forced to undo any changes you have made to your property.

Noise

Modern technology means that the noise created by external units are minimal. However, you should still be considerate towards neighbours and surroundings.

Legislation says that air conditioning units must not exceed 5 decibels above the ambient background noise level measured at any property boundary at peak hours.

Complaints from neighbours and members of the public may result in your unit having to be removed. You may wish to consider some sound proofing such as fences and hedges to keep noise disturbance to a minimum.

Space and boundaries

Always ensure your outdoor AC unit is installed more than a metre away from any property boundaries. It must not be positioned within metre of the edge of a flat roof.

Size

The volume of the external unit must not exceed 0.6m³

Roof installation

It is advised not install your outdoor unit on a pitched roof, otherwise you may have to consult your local council.

Wind Turbines

No wind turbines to be located on the same building or within the curtilage of the building where the AC system is to be installed. (The curtilage of a building or house is the land immediately surrounding it, including closely associated buildings.)

What other air conditioning regulations do I need to be aware of?

If you’re having an air con system fitted in your home, it is very unlikely that you’ll need to file a planning application or worry about legislation (unless your property is listed or located in the restricted areas mentioned above). Your installer should be equipped with this knowledge and highlight anything you need to consider.

Commercial buildings are separate when it comes to regulations, and there are certain requirements which must be adhered to, to ensure you are within government guidelines:

F-Gas

Records must be kept by the building owners/occupiers and systems must be regularly maintained

EPC

By law, all commercial buildings that have over 500m2 if habitable space must hold an energy performance certificate

TM44

All commercial building owner/occupiers that have an AC system must undergo regular inspections by accredited professionals to ensure their system(s) are running efficiently.

Where do I go for advice?

If you are still unsure whether you need to submit a planning application to install an AC system to your property it would be worth contacting your local authority for advice to ensure you are fully compliant.

It is also worth enlisting the help of an AC contractor that is knowledgeable and experienced. Get in touch with our specialist team at Evergreen, we are on hand to offer free advice on any aspect of AC installation.

What is the Best Air Conditioner Temperature for Sleeping?

Posted on 9th February 20229th June 2025 by evergreen

In this article we discuss how room temperature in the bedroom is an important consideration and how your air conditioner can play a key role in helping you sleep well.

Why is a good night’s sleep important?

Most people welcome their comfortable bed after a long day. But apart from the delicious feeling of waking up fully rejuvenated after a restful night, did you know that sleep is vital for survival and health?

We should never underestimate the importance of sleeping well, it is essential to your overall wellbeing, it protects you physically and mentally, as well as boosting your quality of life and improving your performance.

Sleep deprivation is linked to a large range of health conditions including diabetes, depression, obesity, heart attacks and cancer. Lack of sleep suppresses your immune system which leaves you vulnerable to infections and metabolic and hormone changes.

Research suggests that “four in ten people aren’t getting enough sleep, while one in five sleep poorly most nights, representing the second most common health complaint after pain.”

How can we sleep better?

Although sleep is a natural process that our body does involuntarily, our busy lifestyles, and bad habits, often prevent us from getting the good nights sleep that we need. Poor sleep hygiene leads to poor quality sleep, so it is important to create the perfect environment to promote a restful night.

There is a wealth of information available about this subject, in fact hours spent reading the research on this could actually send you to sleep!!! Try cutting out stimulants such as coffee after midday, reducing alcohol consumption and turning off your mobile phone half an hour before you climb under the sheets….. these are simple steps you can take to help you drop off quickly. Excess heat, light and noise can also prevent us from falling asleep and could also be the reason we wake during the night too.

Can an Air Conditioner Help Sleep?

An air conditioner will regulate your bedroom temperature and is a godsend on a sultry summer’s night, but did you know there are other benefits that an air conditioner can provide to help you get off to, and stay, asleep.

Air Conditioners Reduce Humidity

A humid, damp environment can be very detrimental to our health. In fact, enclosed areas where humidity is high, can cause wakefulness and prevent us from sleeping deeply but more concerning is that high humidity is strongly linked to an increase in mould, dust mites, dehydration and heatstroke all of which are harmful to health.

Air Conditioners Reduce Allergens

Air conditioners contain air filtration systems that can reduce dust mites, allergens and pollutants, which can lead to, or exacerbate, respiratory illness.

Air Conditioners Improve Air Quality

Air conditioners can help us to breathe easier, by assisting in the removal of dust and bacteria from the environment.

Air Conditioners Reduce the Risk of Dehydration

Keeping the air at the optimum temperature reduces the amount of water we lose from our body through sweating. When temperatures in the summer months soar, dehydration can be an unpleasant side effect causing headaches, dry mouth and nose, snoring and cramps all of which can be very disruptive and uncomfortable.

Air Conditioners Keep Unwanted Pests at Bay

An invasion of unwanted flying or crawling pests into your bedroom could be very frustrating when you are trying to rest. No one wants to be bitten in their sleep or worst still wants to be chasing an annoying insect around their room in the middle of the night. The installation of an air conditioning system will put a stop to any unwanted visitors of this kind, by being able to maintain a comfortable temperature with windows and doors closed.

Air Conditioners Eliminate Odours and Fumes

If you live in an area that is highly polluted because of traffic volumes, or industrial buildings you can keep your windows and doors shut, whilst still maintaining a comfortable room temperature The air filtration system in your air conditioner can enable you to breathe easier and help to provide cleaner air that is free from odours and fumes.

Air Conditioners Reduce Noise

If your bedroom faces a busy road or you live in a built up area it can be difficult to fall asleep, and stay asleep. The luxury of being able to keep windows and doors firmly closed especially during the hotter months, means that any distraction from outside noise is kept to the minimum.

Is it Better to Sleep in Cooler Temperatures?

During a 24 hour period your body’s internal temperature fluctuates, this fluctuation is all part a natural cycle that we refer to as our body clock. In technical terms this is called your circadian rhythm which regulates your biological and physiological processes. From late afternoon your body decreases in temperature in preparation for the nocturnal sleep phase. With this in mind it makes good sense to be mindful of your bedroom temperature, keeping the temperature cooler rather than hotter.

What is the Perfect Air Conditioner Temperature for Sleeping?

Most people will agree that a comfortable bedroom temperature is key to achieving a good quality night’s sleep in fact a National Sleep Foundation Poll concluded that “two-thirds or more rated the following elements as important in getting a good night’s sleep: Cool room temperature (79%) Fresh air, free of allergens (75%)”.

Adjusting or programming your air conditioner to maintain the best room temperature to sleep in is key to improving your sleep quality, of course this varies from person to person, but it is recommended that you set your thermostat somewhere between 20 and 24°C. In the industry any temperature within this range is classed as comfort cooling, which of course is self explanatory. There will be other variables that affect your decision though, for example, you may prefer thicker bedding or nightwear and a lower temperature or vice versa.

What is sleep mode in my air conditioner?

If you air conditioner comes equipped with this function, your room temperature will automatically be regulated to keep you comfortable through the different stages of sleep, decreasing or increasing room temperature in line with your body’s natural sleep cycle.

This also ensures that your AC system is working economically, so you can rest assured that you are helping to keep your energy bills low.
