Evergreen expand to Hertford!

We are very excited to announce that, following the continued success and growth of Evergreen, we have recently acquired new premises, in Cole Green, Hertford (Hertfordshire).

For many years we have been operating out of our Wickford office providing air conditioning installation, and related services, to Essex and beyond, and opening a second office is something we have been discussing for some time.


It has been a busy few weeks, purchasing and assembling the furniture and making sure that we have everything we need in one place.

It has quite literally been all hands-on deck, even Maggie the office canine, and head of security, has been shifting cardboard boxes back and forth (and tearing up a fair amount of them too!)

Our new office is a beautiful, listed building, which has been carefully renovated to keep its existing features whilst a providing bright, spacious, and welcoming place to run our business from.

Time for a break and some well-earned refreshment!

Ideally located in a rural setting just outside of Hertford, we are now perfectly positioned to offer our air conditioning services throughout Hertfordshire, with the added bonus of a beautiful setting with plenty of car parking for visitors and staff alike.

If you are based in Herts and are interested in having domestic or commercial air conditioning installed, or you need to book a service or maintenance visit, please drop us a line.

Or if you happen to be passing, do call in for a cup of coffee at our Hertford office, we would love to show you around!
