Air conditioning installation in New Denham
Across New Denham, every installation follows the same steps: a site survey, or photos for simple jobs, then a fixed-price quote, the installation, commissioning and F-Gas records. You know the price before work begins and the paperwork is in your hands when we finish. Most split systems we fit in New Denham are reversible: the Energy Saving Trust notes that air-to-air heat pumps are sometimes called air conditioning, so a system bought for summer earns its keep in winter too.
Around New Denham, many people choose a system that heats as well as cools, which suits rooms the main heating doesn’t reach well, such as a garden room or loft.
Whatever the visit, you get a written record: commissioning details and F-Gas records for a new system, a note of the fault and the fix for a repair, or a service record. File it with the manual so it’s to hand next time.

After we’ve gone
How well a system lasts depends on use and care. Here’s what we suggest:
- Refit filters properly after cleaning
- Keep the indoor unit’s filters clean
- Flag any change in how the system sounds or performs
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 are confident using it.
Do not ignore small changes. A drip, a noise or a flashing light is often an early sign of a fault and catching it early keeps the repair small.
Common questions in New Denham
Is New Denham within the area you cover?
Yes, and the size of the place makes no difference to how we work. Send a few details and pictures, and we reply the same working day.
Do I need planning permission for air conditioning in New Denham?
It depends on the property. Central New Denham is a short walk from the Uxbridge Lock Conservation Area. A system that heats as well as cools may not need an application on a house, provided it stays within the permitted development limits. Cooling-only units get no such allowance, and listed buildings and road-facing positions in conservation areas need more care. We speak to Hillingdon council, which is normally the planning authority for New Denham when it matters.
Are you F-Gas certified?
AirCon Doctor is an F-Gas certified company, NICEIC approved for electrical work and MCS certified for heat pumps. We’re also Checkatrade members.
Can the outdoor unit go on a roof or at ground level?
The position is agreed on the survey, not on the day. It must have clear airflow and space for servicing, and a position facing a road can bring extra planning considerations. We explain the options and any permissions to check.
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 the survey covers each of them.
Will you work on another installer’s system?
Yes. We look at it first and tell you what we find, including anything about the original installation that needs putting right. Any work is priced before it goes ahead.
Do you work on all makes?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For new systems, we recommend a brand and model to suit the job and explain why.
Common problems we fix in New Denham
Many people try a portable unit first. A portable unit has to vent its warm air through a hose out of a window, which lets some heat back in, and its compressor sits in the room with you. With a split system, the compressor lives outside.
Look out for these signs:
- Fans and portables that do not keep up
- A loft room or top floor that bakes in summer
- Too many options and no clear advice
If your home is in one of the older streets near St Francis, it’s worth checking whether it’s listed or in a conservation area before an install.
Questions to ask before booking
- Whether anyone has checked the property or the system first
- What happens if the job turns out to be different on the day
- How VAT is shown, and which rate applies
Owner checks or an engineer?
Write down what you notice: error codes, noises, drips, smells or a drop in performance. It helps us diagnose quickly, 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: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If a breaker trips again after you reset it, leave it off and call us on 07833 053749 or write to us at info@aircondoctor.co.uk.

How the visit works
Each visit follows the same order: agree the plan on site, put the dust sheets down, do the work, test what we’ve done and explain it all to you. On site, the work takes about a day for a single-room system, longer for multi-room and ducted systems. For a village like New Denham, tell us about narrow lanes, gates and parking when you book.
- First comes a site survey, or pictures and measurements for a straightforward job.
- We size the system for each room, then send a fixed-price quote with the units and where they go.
- The units go up and the pipework, cable and condensate drain are run neatly between them.
- The electrical supply is connected, and the refrigerant circuit is pressure tested and evacuated.
- The system is commissioned and checked in every mode, and we hand over the controls, F-Gas records and warranty information.
Preparing for the visit
- Name a contact who can meet us at the agreed time
- Let us know if the building has a permit or sign-in process
- Tell us about access, such as roof hatches, high walls or locked plant areas
Getting a price
Quoting starts with a diagnosis, from a site survey or, where the job is straightforward, from photos and measurements. After that, we send a fixed price so you know the cost before we begin.

Air conditioning in New Denham: the local picture
The Valuation Office Agency’s council tax figures show about 37% of homes across New Denham and its surrounding area were built in 2000 or later, and about 50% of households live in flats, according to the 2021 Census. Newer homes are often easier to fit, with cavity walls and space in the loft for pipework. For a flat, we look at balconies, flat roofs and rear walls for the outdoor unit, and the lease often needs checking first.
Ickenham Hall, about 2.1 miles 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.
