High Barnet: your questions answered
Can you fit air conditioning in a London flat in High Barnet?
Typically, yes, though leaseholders normally need the freeholder’s agreement. We look at where the outdoor unit could go, such as a balcony, flat roof or rear wall, and write it up for the freeholder or agent.
Do you cover High Barnet for air conditioning?
We do: High Barnet falls inside our working area. Get in touch with the details and we reply the same working day.
Do you have a 24/7 line?
Yes, any time. If something urgent happens, like water coming from a unit or a critical room overheating, call our 24/7 line and we will agree what happens next.
How quickly will you reply?
The same working day. After that, we agree a survey, diagnosis or installation date that suits you, and you get a fixed price before any work goes ahead.
Is air conditioning possible in a flat?
That depends on the lease, the building and where the outdoor unit could go. An outdoor unit can sometimes go on a balcony, roof or rear wall, with consent, and we check the options on the survey. This is general information, not legal advice.
Do I need to service the system to keep the warranty?
It can, for some brands. Read the manufacturer’s terms, or send us the make and model and we’ll explain them and stick to the interval they set.
Can you look at a system you didn’t fit?
Yes. We start with a proper look and tell you honestly what we find, including any issues with how it was fitted. You get a fixed price before any work goes ahead.
Air conditioning for homes and businesses in High Barnet
Across High Barnet, every installation follows the same steps: a site survey, or pictures for simple jobs, then a fixed-price quote, the installation, commissioning and F-Gas records. You know the price before we start and the paperwork is in your hands when we finish. Most split systems we fit in High Barnet 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.
In a London area like High Barnet, many of the homes we are asked about are flats, maisonettes and terraced houses. So the first questions are where the outdoor unit can sit, how the pipes get to it and whose permission is needed. A freeholder or managing agent often has a say in a flat, so we write up the proposed positions for them to see.
Refrigerant work is written up in the F-Gas records: what was done, the refrigerant type and any amount added or recovered. Keep the records with the manual and the warranty documents, as a manufacturer or a future engineer may ask to see them.

What owners can safely do
Keep a note of anything odd: an error code, a new noise, a drip, a smell or a change in how well the system heats or cools. It makes our diagnosis quicker, and a photo or a short video of the display is even better.
Before you call us about a fault, a few checks can save a visit: check the mode, the set temperature, the remote’s batteries and the breaker. If the breaker trips a second time, leave it off and ring 07833 053749 or send an email.
Air conditioning around High Barnet
About 42% of homes in and around High Barnet were built before 1919, according to VOA council tax data. Older homes often have solid walls, which take longer to core drill, so we plan pipe routes carefully and keep them as discreet as we can. For a London home, we plan the outdoor unit position, the pipe route and any approvals before the day.
Homes near Christ Church are a good example of where we look up the heritage status of the building before fixing anything to it.

When it’s something else
In fairness, there are a few things this work will not fix:

- Damp or condensation caused by leaks or poor ventilation in the building (that needs the cause fixing)
- An installation that needs consent nobody has given yet

When to call us in High Barnet
Portable units are often where people start, and why they call us. Portables push their warm air out through a hose in the window, so the window cannot close properly and the noisy part of the unit is in the room. A fixed split system puts the compressor outside.
What we are most often called about:
- Portable units that are noisy and barely cope
- A system on old refrigerant that’s due for replacement
- Rooms that get too hot to sleep or work in
Wyllyotts Manor, about 2.9 miles north, is one of the historic houses nearby, and if your own home is listed, consent comes before any air conditioning is fixed to it.
Questions to ask before you book
- Whether the quote is a fixed price
- Whether the manufacturer’s warranty depends on regular servicing
- Whether a new circuit is included and who certifies it
What happens on the day
There’s very little for you to do on the day. Just let us in and point us to the units, or to where they’ll be fitted, and the rest is down to us. At the end, we tidy up and run through the work with you. Pictures of the space and the outside wall help us plan the work in High Barnet.
- 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.
- Checks: a pressure test for leaks, then a vacuum to clear moisture.
- The sign-off: commissioning, a walk through the controls, and the F-Gas records and warranty details.
Preparing for the visit
- Clear access to the fuse board
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Plan for pets to be kept clear during the visit
