Air conditioning near Barnet

After we have gone

A little care keeps the system in better shape. Our advice:

  • Refit filters properly after cleaning
  • Report drips, noises or error codes right away
  • Keep the room closed while it runs

An annual service keeps the system running efficiently, and some manufacturers make regular servicing a condition of their warranty. We’ll remind you when it’s due, so it doesn’t get forgotten.

Use sensible settings. Choose the right mode and a comfortable temperature rather than the lowest setting, and close windows and doors while it’s cooling.

Air conditioning for homes and businesses in Barnet

We approach an installation much as a doctor approaches a patient: survey first, install second, commission and hand over last. The sign-off includes testing every mode, showing you the controls and handing over the F-Gas records. Every installation in Barnet begins with a look at the rooms, the walls and where the outdoor unit can go, followed by a fixed-price quote with the brand, model and every part of the job set out.

In Barnet, as across London, the rooms that get hottest are usually under the roof or behind large sunny windows. A single wall-mounted unit in the worst room is often where people start, and a multi-split can cover more rooms from one outdoor unit where space outside is short.

AirCon Doctor is an F-Gas certified company and NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

Your questions about air conditioning in Barnet

Do I need permission to put air conditioning in my flat in Barnet?

In many cases, yes, once the lease and the building’s rules are checked. 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.

How do I get a quote for air conditioning in Barnet?

Send us photos of the room or the system and a few details about the property. Simple jobs can be priced from pictures; otherwise we arrange a site survey and then give you a fixed-price quote.

Will you make a mess?

We put dust sheets over floors and furniture near the work first, and the area is kept tidy throughout. At the end, we clear up and show you what we’ve done.

Can you fit air conditioning in a leasehold flat?

In many cases, but permissions come first. Leaseholders normally need consent from the landlord or management company for an outdoor unit and holes through outside walls, so check the lease. Permitted development rules for flats are also tighter than for houses, so we point out anything that may need permission on the survey. This is general information, not legal advice.

What size air conditioning unit do I need?

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 the survey covers each of them.

Which manufacturers do you install and repair?

We work with the leading brands, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we’ll take it from there.

How quickly will you reply?

On the same working day you contact us. After that, we agree a survey, diagnosis or installation date that suits you, with a fixed price before work starts.

Why it’s worth doing now in Barnet

Putting up with another summer of portable units and fans rarely makes sense. A properly installed split moves heat outside, keeps the noisy parts out of the room and most of the time heats too, so it works for you in winter as well. In a London building, getting the freeholder’s or agent’s agreement can take a while, so it’s worth starting early.

The price reflects the work, not guesswork. That is why every job is looked at first, and why the quote is fixed before work begins.

What you get with us

  • A fixed price before any work starts
  • 24/7 emergency line for breakdowns
  • One contact for properties across the South East and London
  • NICEIC approved for electrical work

The process

The visit has three parts, a bit like a doctor’s appointment: look, put right and sign off. First we check the system or the space against the plan, then we do the work, and finally we test, record and explain. Most of the time goes on the middle part, which takes a day or more, depending on the number of rooms, the pipe routes and the access. Some blocks in Barnet need contractor details in advance, so tell us what your building needs.

  1. First comes a site survey, or photos and measurements for a straightforward job.
  2. We size the system for each room, then send a fixed-price quote with the units and where they go.
  3. The indoor unit is fixed in place, the outside unit positioned, and the connecting runs put in tidily.
  4. We connect the supply, pressure test the pipework and evacuate it before the refrigerant is released.
  5. Finally, it’s commissioned, tested in each mode and handed over with the F-Gas records.

Getting ready for the visit

  • Mention any parking restrictions near the property
  • Clear a path to the units and the space around them
  • Let us know if the building has a permit or sign-in process

Getting a price

Quoting starts with a diagnosis, either on a site survey or, for simple jobs, from your photos and details. After that, we send a fixed price before any work starts.

Advice

What an install looks like in Barnet

About 49% of households live in flats, according to the last census (2021). In flats, the lease and the freeholder usually decide where an outdoor unit can go, and the permitted development rules for flats are tighter. For a London home, we plan the outdoor unit position, the pipe route and any approvals before the day.

If your home is in one of the older streets near St John's United Reformed Church, it’s worth checking whether it’s listed or in a conservation area before an install.

Do you need air conditioning in Barnet?

Most overheating comes from heat gained through the day. Sunshine through glazing, especially on south and west-facing rooms, adds a lot of heat, and the heat lingers long after the sun has moved round.

Look out for these signs:

  • Rooms that get too hot to sleep or work in
  • Commercial rooms that are too warm for staff
  • An old system that needs replacing

If you work from home near New Barnet station, a home office that overheats is one of the easiest rooms to cool.
