- Rooms under the roof that stay hot into the night
- Not knowing which system, size or brand to choose
The process
Protection comes first: dust sheets over floors and furniture near the work, and we ask before moving anything. After that, anything electrical is made safe and we start. The work on site takes a day or more, depending on the number of rooms, the pipe routes and the access, and we clear up before we go. Before a visit in Winchmore Hill, we ask where the van can stop and how we reach the outdoor unit.
- First the diagnosis: a survey of the rooms, the walls, the outside and the electrics.
- Next, a recommendation for each room and a fixed price.
- Then the work: units up, pipes and drain run, and a new circuit where necessary.
- Testing: the circuit is pressure tested and evacuated before the refrigerant is released.
- Finally, the clean bill of health: commissioning, the controls explained and your paperwork handed over.
Before we arrive
- Let us know if the building has a permit or sign-in process
- Make sure we can reach the outdoor unit, or where it will go
- Clear the space around the indoor unit, or where it will go

Photos are enough for some jobs; others need a visit first. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, you get a fixed price before any work is booked.

Air conditioning installation in Winchmore Hill
Wall-mounted, multi-split, ducted and cassette systems are all part of what we install, with VRF for larger buildings. Which one suits you depends on the space, the building and how much of the unit you want to see, and we explain the options on the survey. Most split systems we fit in Winchmore Hill are reversible: in heating mode they work as an air-to-air heat pump, so a system bought for summer earns its keep in winter too.
Sizing is where cheap installs go wrong: we look at the room’s size, windows, insulation and use before choosing a unit.
Space outside is often tight in Winchmore Hill, as in much of London, which means a rear wall bracket, a flat roof or a balcony is often the best spot for the outdoor unit. We look at noise towards neighbours and windows as well as looks, and the pipe run is planned to be short, neat and out of the way.
Each manufacturer sets its own warranty period. For instance, Daikin’s standard warranty on split air conditioning is 2 years, and its longer extensions apply to its air-to-water units only. Whatever the brand, the manufacturer’s terms are explained on your quote.

Keeping the system healthy
Think of this as the after-treatment advice, in brief:
- Report drips, noises or error codes straight away
- Book an annual service
- Keep the room closed while it runs
Commissioning is the last stage: every mode is tested before we go. We check it’s running as the manufacturer intends, then show you the controls and the timer, so you’re confident using it.
Set it and leave it. A moderate set temperature cools the room just as well as the lowest one, without the waste and keep doors and windows shut while it runs.
Before you call an engineer
There are a few things you can safely do yourself: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Opening up the units, the electrics and the refrigerant circuit are a job for us.
For air conditioning, cleaning the indoor unit’s filters is the main job owners can do where the manufacturer’s manual explains how. With the power off, they lift out, can be vacuumed or rinsed and must be fully dry before they go back. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.
Common problems we fix in Winchmore Hill
Some people come to us for heating rather than cooling. Old direct electric heaters turn electricity straight into heat, while a heat pump moves heat in from the outside air, which means more heat out than electricity in. That’s how most modern split systems work.
Common reasons people call us are:
- Expensive direct electric heating
- Portable units that are noisy and barely cope
- Rooms under the roof that stay hot into the night
Bruce Castle, about 2.6 miles south-east, is one of the historic houses nearby, and if your own home is listed, consent comes before any air conditioning is fixed to it.

Homes in Winchmore Hill and air conditioning
About 56% of homes in the Winchmore Hill area were built between the wars, according to VOA council tax data. We check the wall construction on homes of that age, as it decides how the pipework goes through. London installs often hinge on outside space, the lease and access to the building.
Older streets near Holy Trinity may fall within a conservation area, so we check the planning position before choosing where the outdoor unit goes.

Your questions about air conditioning in Winchmore Hill
Can you do air conditioning in Winchmore Hill?
Yes. Winchmore Hill is one of the places we cover. Tell us a little about the job and we will take it from there.
Is air conditioning in Winchmore Hill permitted development?
It depends on the property. A conservation area takes in the middle of Winchmore Hill. Put simply: reversible systems on houses can be permitted development, cooling-only ones cannot, listed buildings need consent, and conservation areas limit outdoor units facing a road. When your property needs a decision, we contact the planning department at Enfield council, usually the authority for Winchmore Hill.
Do you survey before quoting?
Yes, every time. Diagnosis comes before treatment: the survey tells us what the job needs and how to do it and the fixed price is built on it.
Do I need a new electrical circuit?
Most of the time, yes: a dedicated circuit is needed. Adding a new circuit is notifiable building work under Part P unless it’s done by a registered competent person, and we’re NICEIC approved, so we can install and certify it.
How do I know what size unit to get?
Floor area is only part of it. Windows, the direction the room faces, the roof above and the people and equipment in it all count, and we take them all into account on the survey.
How long will the installation take?
It takes a day or more, depending on the number of rooms, the pipe routes and the access. We confirm the time when we quote so there are no surprises.
Does air conditioning work as heating?
In most cases, yes. Running as a heat pump, it moves heat in from outside rather than making it from electricity alone. If you want it to replace your main heating, ask about air-to-air heat pumps and the conditions for the Boiler Upgrade Scheme grant.
From one of our customers
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
