Air conditioning installation in Harlow
Need a room cooled or heated properly? We install wall-mounted split systems for households and small firms in Harlow and nearby towns. The job covers a site visit, a written price, pipework, electrics, testing and a handover, so you end up with a room you can actually use in August.

What does installing a split system involve?
There are two pieces of equipment. Inside, a long slim unit is fixed near the ceiling. Outside, a larger box with a fan stands on a low plinth or hangs from brackets. Copper refrigerant lines, an electrical feed and a plastic condensate pipe run between them. Put the two back to back and hardly anything shows. Put them apart and the bundle goes through the loft, or down an outside wall inside plastic cover strip.
What gets checked on the first visit?
A good fit is mostly decided before anyone unpacks a drill. We go through:
- how big the room is, and how much sun it takes
- whether the wall can carry the unit and leave the air a clear path
- which way the condensate can run, since water only flows downhill
- where the fan unit can breathe without facing a neighbour's bedroom
- how much room is left in your consumer unit, or fuse box
- whether anyone else has to sign the work off
That last check catches a lot of homes in Harlow. About 29% of households here rent from a social landlord, according to the 2021 Census, and Harlow Council says no alteration may start until it has given permission in writing.
Why are the electrics priced separately?
Most wall units want a dedicated supply plus a weatherproof isolator beside the outdoor unit. Checkatrade's May 2026 figure for that is £400 to £700, which makes it the biggest add-on you are likely to see. England treats a new circuit as notifiable under Part P, so either a registered electrician does it or building control signs it off. File the certificate with your house papers, because buyers' solicitors ask for it.
How the system is tested and commissioned
With both units up, the pipework is pressurised to prove it holds, then evacuated so no air or moisture stays inside. Refrigerant goes in, the system starts and temperatures are read off. The law reserves this stage for someone with an F-gas qualification. R32, now the usual refrigerant, is mildly flammable, which limits how much can serve a very small room, so that gets worked out at the design stage. Before we leave, you should know the remote and hold a written record of the equipment. Here is how to check an F-gas certificate.
What decides the price of an installation?
Four things mainly: capacity, the pipe route, how high the outdoor unit sits, and the electrics. The cheapest case is a ground-floor room on an outside wall with both units back to back. The dearest is a top-floor flat with a long route and an outdoor unit far below. For national numbers, and a way of weighing up rival quotes, read what air conditioning costs.
Questions people ask
Will the installation be messy?
Coring through the wall makes dust. Clear anything delicate from around that wall beforehand, or mention it when we visit.
Could the outdoor unit go on my roof?
Not on a pitched roof without a planning application. Flat roofs can work if all of the unit is a metre or more in from the edge. The planning guide has the rest.
Do I have to have a new circuit?
In most cases, yes, though that depends on the unit's rating and your consumer unit. We look at both and list the cost separately.
I bought a unit online. Will you fit it?
Send us the make and model before you commit. Pre-charged kits are still covered by the F-gas rules on who may handle them.
