About our air conditioning in Harrow Weald
Air conditioning isn’t only for summer: most modern splits heat too. The Energy Saving Trust makes the same point: an air-to-air heat pump is what many people simply call air conditioning, and a well-chosen system can earn its keep all year round. A lot of the calls we get from Harrow Weald are about one room that is too hot to sleep or work in. That is typically a single wall-mounted split, from £1,200 + VAT.
A single room takes a day in most homes, while multi-split systems for several rooms can take longer.
Top-floor flats and rooms with big south- or west-facing windows tend to be the first to overheat in London. 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.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We’ll tell you how the manufacturer’s warranty is likely to apply before any chargeable work goes ahead.

What air conditioning can’t fix
Before booking, it helps to know what’s not included:
- Damp or condensation caused by leaks or poor ventilation in the building (that needs the cause fixing)
- Heat loss through very poor insulation (a system will heat the room, but insulation is a separate job)
- Stuffy rooms that need fresh air rather than cooling
If you are not sure, just call us on 07833 053749 or drop us a line and we’ll give you a straight answer before you book.

What affects the cost of air conditioning
The price is fixed before any work begins. It takes into account:
- How many units are involved
- One-off work versus a regular service cycle
- Whether the existing supply is suitable
What you pay reflects the actual work. That’s why every job is looked at first, and why the quote is fixed before any work starts.
What to send for a quote
To speed up the quote, send us:
- The outside wall, roof or yard where the outdoor unit sits or would go
- A short video of any fault, such as a noise or a flashing light
- Any previous service or F-Gas records
The quickest way to a quote is to send pictures: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Tell us the address and what you need, and simple jobs can often be priced without a visit.
The process
On the day, we arrive at the time agreed with you and check the plan with you first. Floors and furniture near the work are covered with dust sheets, and anything electrical is made safe before work starts. On site, it takes a day or more, depending on the number of rooms, the pipe routes and the access. Pictures of the space and the outside wall help us plan the work in Harrow Weald.
- You send pictures, or we visit and survey the rooms and outside.
- The system is sized, positions are agreed and the price is fixed.
- On the day, dust sheets go down and the indoor and outdoor units are fitted.
- We run and connect the pipes, cable and drain, then pressure test and evacuate the circuit.
- It’s switched on, checked and handed over with its records.
Getting ready for the visit
- Tell us about parking and loading
- Find the manual or the paperwork for the system, if you have it
- Keep pets and children away from the work area

FAQs for Harrow Weald
Do I need permission to put air conditioning in my flat in Harrow Weald?
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.
Is planning permission needed for air conditioning in Harrow Weald?
It depends on the property. Central Harrow Weald sits inside a 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 Harrow council, which is normally the planning authority for Harrow Weald when it matters.
Can you fit air conditioning in a leasehold flat?
It depends on the building and the lease. Balconies, flat roofs and rear walls can all work, subject to consent and the survey looks at every option. This is general information, not legal advice.
Which type of air conditioning is best?
Number of rooms, space outside and how much of the unit you want to see all decide it. Ducted systems need a ceiling void or loft, and cassettes need a suspended ceiling, which we check on the survey.
How do I know what size unit to get?
We size each room on the survey, from its size, glazing, orientation and use. Too small, and it runs flat out; too big, and it switches on and off and wastes energy, so we explain why we’ve chosen a particular output.
Is Harrow Weald in your area?
Yes. Harrow Weald is part of the area we cover, within the South East and London area we cover. Our base is in East Grinstead, West Sussex.
What does it cost to install air conditioning?
Typically £1,200–£2,200 + VAT for a single-room split, depending on the room, the access and the pipe route. Where you sit in the range depends on pipe length, access, electrics and the model, while commercial systems are priced after a survey.
System by system
Electrical supply
The fuse board is looked at during the survey, so any extra electrical work is on the quote rather than a surprise on the day. An older board may need extra work and we will tell you if yours does.
Wall-mounted split systems
A single-room split is typically £1,200–£2,200 + VAT, with supply, fitting, commissioning and the F-Gas paperwork included. Long pipe runs, difficult access and a new circuit affect where your job sits in the range.
From one of our customers
“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
