Heston air conditioning
Looking for air conditioning in Heston? We look at the job first, give you a fixed-price quote and do the work at a time that suits you, finishing with proper records.
- A room that is unbearable on warm days
- A study or office that overheats during the day
- Too many options and no clear advice
When something else is needed
We won’t sell you work that does not address the problem, so here are the limits:
- An installation that needs consent nobody has given yet
- A lack of fresh air (most split systems recirculate room air rather than bringing fresh air in, which is a job for ventilation)
- Gas boiler or central heating faults (we don’t work on gas boilers)
Not sure which it is? You can give us a ring on 07833 053749 or use the quote form and we will tell you honestly.
Parts of the system we cover
- Air-to-air heat pumps
- Multi-split systems

Air conditioning installation in Heston
We approach an installation much as a doctor approaches a patient: the survey diagnoses what the rooms need, the installation is the treatment and commissioning is the sign-off. The sign-off includes testing every mode, showing you the controls and handing over the F-Gas records. For air conditioning in Heston, one call covers the survey, the fixed-price quote, the installation and the F-Gas paperwork, wherever you are in Greater London.
The electrics are part of the job: a dedicated circuit where the unit needs one, certified under NICEIC, so there’s no separate electrician or building control visit to arrange.
In Heston, as across London, the rooms that get hottest are typically under the roof or behind large sunny windows. A single wall-mounted unit in the worst room is often where people start, while a multi-split serves several rooms from one outdoor unit, which helps where outside space is limited.
Warranty periods vary by brand and by product. Daikin, for example, gives a standard 2 years on split air conditioning, with longer extensions only on its air-to-water heat pumps. For any other brand, we explain the manufacturer’s terms on your quote.

Why it’s worth doing now in Heston
Fans and portables move warm air around rather than removing it. A properly installed split moves heat outside, keeps the noisy parts out of the room and in most cases heats too, so it works for you in winter as well. Planning ahead in Heston means you choose the date, not the weather.
No two properties are the same, so we price each one individually. The equipment, how we reach it, the route between units and the work needed all make a difference.
Why book with us
- Leading brands including Daikin, Mitsubishi Electric and Fujitsu
- A site survey and a fixed-price quote
- Emergency calls taken 24/7
- Warranty terms set out brand by brand

Common questions in Heston
Can you do air conditioning in Heston?
Yes. Heston is one of the places we cover. Tell us a little about the job and we will take it from there.
Do I need permission to put air conditioning in my flat in Heston?
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.
Can I fit air conditioning or a heat pump myself?
Not the refrigerant work. The F-gas rules require certified companies and qualified engineers for it, and a new electrical circuit is notifiable building work unless a registered competent person does it.
Does air conditioning need its own electrical supply?
Usually, yes. The fuse board is checked on the survey, and any electrical work goes on the quote and we install and certify the circuit as NICEIC approved contractors.
How soon will you get back to me?
On the same working day you contact us. After that, we agree a survey, diagnosis or installation date that suits you, and you get a fixed price before any work goes ahead.
Do you look at the job first?
Yes. Every job is looked at first, either on a site survey or from photos and details for simple jobs. Then you get a fixed-price quote.
How much is air conditioning for one room?
From £1,200 + VAT for a single-room split, with a typical range of £1,200–£2,200 + VAT. The price includes supply, installation, commissioning and F-Gas documentation, and we fix it after a survey or from your pictures.
Before you call an engineer
On air conditioning, the filters in the indoor unit are typically the one part owners can clean where the manufacturer’s manual explains how. They come out, get a gentle clean and go back only when they’re dry. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
Before you call us about a fault, a few checks can save a visit: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If the breaker trips a second time, leave it off and phone 07833 053749 or write to us at info@aircondoctor.co.uk.
Air conditioning around Heston
Valuation Office Agency council tax records show about 44% of homes in the Heston area date from 1919 to 1939. Homes of that age normally have cavity or solid brick walls, and we check which before planning the pipe route. For a London home, we plan the outdoor unit position, the pipe route and any approvals before the day.
About 1.2 miles east stands Osterley House. Listed homes in any area need consent first, so tell us if yours is one. Around St Leonard's Church, a quick check of the listing and conservation maps is part of planning any install.

How the visit works
Where something has to be switched off during the work, we agree it with you first, so you can plan around it. In a business, work can often be done one area at a time. On site, it takes anything from a day for one room to several days for a multi-room or ducted system. A few pictures of the room, the outside wall and the fuse board help us plan a job in Heston.
- First comes a site survey, or photos and measurements for a straightforward job.
- You receive one fixed figure covering the kit, the fitting and the positions we agreed.
- The indoor unit is fixed in place, the outside unit positioned, and the connecting runs put in tidily.
- Power is wired in, the joints are proved leak-tight under pressure and a vacuum pump draws out air and moisture.
- Last comes the run-up: every mode checked, the controls explained and the paperwork left with you.
Preparing for the visit
- Plan for pets to be kept clear during the visit
- Clear access to the fuse board
- Give us access to the outside wall, roof or yard where the outdoor unit sits
