Air conditioning for homes and businesses in Colwood
We fit wall-mounted splits, multi-split systems, ducted systems and ceiling cassettes, plus VRF systems for bigger commercial buildings. Which one suits you depends on the space, the building and how much of the unit you want to see and we talk you through it on the survey. Air conditioning installation in Colwood starts with a site survey, then a fixed-price quote that names the make and model.
New circuits are done by our NICEIC approved electricians, so the electrical paperwork comes with the installation.
Villages like Colwood often have older houses and cottages, some of them listed. We check that first, because permitted development does not apply within the grounds of a listed building.
Refrigerant work is written up in the F-Gas records: the work carried out, the refrigerant involved and the quantities. Keep the records with the manual and the warranty documents, ready for the next service or a warranty query.

Honest limits
Not every problem is solved by air conditioning, and we’d rather say so up front. It won’t put right:
- Heat loss through very poor insulation (a system will heat the room, but insulation is a separate job)
- Building damp that has a structural cause
- Stuffy rooms that need fresh air rather than cooling
If in doubt, call 07833 053749 or email us and we will say what we think.
What we work on in Colwood
- Ducted systems
- VRF systems
- Ceiling cassettes
- Air-to-air heat pumps
- Wall-mounted split systems
- Multi-split systems
Why deal with it now?
New systems now use lower-impact refrigerants. Since 2025, new single split systems with less than 3 kg of refrigerant cannot use F gases with a GWP above 750, so new splits use refrigerants such as R32, with a GWP of 675. R410A, used in many older systems, has a GWP of 2088. For a village like Colwood, booking ahead lets us plan the trip properly.
No two properties are the same, so we price each one individually. The system, the access, the pipe routes and the parts involved all make a difference.
Why book with us
- Leading brands including Daikin, Mitsubishi Electric and Fujitsu
- F-Gas certified company

Colwood questions
Can you do air conditioning in Colwood?
Yes. We work across London and the South East from our base in East Grinstead, and Colwood is part of that. To start, give us a ring on 07833 053749 or write to us at info@aircondoctor.co.uk with a few photos.
Can I fit air conditioning in Colwood without planning permission?
It depends on the property. Around 3 listed entries sit within 0.5 miles of central Colwood. An air-to-air system used for heating as well as cooling can be permitted development on a house if it meets the conditions, but a cooling-only unit isn’t covered, listed buildings need consent and conservation areas restrict outdoor units facing a road. Where needed, we check with the local planning authority (for Colwood, normally Mid Sussex council).
Can you set up regular servicing?
Yes. Send details of the systems and how they’re used, and we’ll suggest a schedule with a fixed price. Leak checks required by the F-gas rules can be built in for larger systems.
Can I fit air conditioning or a heat pump myself?
No, not the refrigerant side. The F-gas rules require certified companies and qualified engineers for it, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.
Do you protect the property while you work?
We put dust sheets over floors and furniture near the work first, and we tidy up as we go. At the end, we clear up and show you what we’ve done.
What does F-Gas certified mean?
For refrigerant work, both the engineer and the company need the right F-gas credentials. It’s worth checking before you book, and we are happy to show ours.
Do I get paperwork after the visit?
Yes. You get a written record of each visit, and any work on the refrigerant circuit goes in the F-Gas records. Keep them with the manual and the warranty documents.
How it works
Every visit follows the same order: check the plan with you, put the dust sheets down, carry out the job, check the system and talk you through it. On site, the work takes about a day for a single-room system, longer for multi-room and ducted systems. We plan the trip to Colwood around you.
- We survey the rooms and the outside of the property, or work from pictures and details for simple jobs.
- Each room is sized and you get a fixed-price quote setting out the equipment and the unit positions.
- Brackets go on, the units are hung and the refrigerant lines, cable and drain are routed between them.
- Once the electrics are connected, the pipework is tested for leaks and put under vacuum before any refrigerant flows.
- Last comes the run-up: every mode checked, the controls explained and the paperwork left with you.
Before we arrive
- Tell us about parking and loading
- Let us know if the building has a permit or sign-in process
- Plan for pets to be kept clear during the visit
How to get a quote
Our prices page gives typical ranges, but your quote is based on your job, because every property is different. After a look at the job, by photos or a survey, the price is fixed. To start, give us a ring on 07833 053749 or use the quote form.

Homes in Colwood and air conditioning
Valuation Office Agency council tax records show about 36% of homes in the Colwood area were built in 2000 or later, and the 2021 Census found about 74% of households in detached or semi-detached houses. Newer homes are often easier to fit, with cavity walls and space in the loft for pipework. Houses typically have a side or rear wall with room for the outdoor unit, and a multi-split can serve several rooms from one outdoor unit.
Tyes Place, about 3.4 miles north-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.

Do you need air conditioning in Colwood?
Rooms in the roof are often the hardest to keep cool. The roof takes the full force of the sun, and warm air rises from the floors below, which is why a loft bedroom can still be warm at bedtime.
Look out for these signs:
- Fans and portables that do not keep up
- Commercial rooms that are too warm for staff
- A loft conversion that’s too warm to use
Most people start with the room that gets hottest, then add more rooms on a multi-split if needed.
Before booking anyone
- Who does the electrical work, and whether they can certify it
- If the figure could change on the day
- The make and model of any parts or equipment being quoted

“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
