Air conditioning for homes and businesses in Chertsey
We install leading brands, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. We recommend a model on the survey and explain why it suits the room, along with the manufacturer’s warranty terms on your quote. Most enquiries from Chertsey start with one hot room: a bedroom, a home office or a loft conversion. A single-room split system is often the answer, from £1,200 + VAT.
Homes around Chertsey are mostly houses, many with gardens, which usually leaves room for an outdoor unit. The bigger questions are the wall construction and the route back to the consumer unit.
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.

Before you call an engineer
Owners can handle the everyday basics: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Opening up the units, the electrics and the refrigerant circuit are a job for us.
Leave the units and pipework where they are. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrical side needs a competent person. Ask us to quote for a move instead.
What else we do in Chertsey
How it works
We book the visit for a day and time that suit you, and we keep you posted if anything changes. When we arrive, we check the job against the survey or the photos you sent. If something is different, we talk it through with you before carrying on. After that, it takes a day or more, depending on the number of rooms, the pipe routes and the access. In a place like Chertsey, parking is rarely an issue, but tell us about gates and access to the back of the property.
- First comes a site survey, or pictures and measurements for a straightforward job.
- Cooling loads are worked out room by room, and the written price names the make, the model and every position.
- 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.
- We commission the system, show you the controls and leave the F-Gas records and the manufacturer’s warranty details.
Getting ready for the visit
- Keep pets out of the rooms we are working in
- Let us know where the consumer unit is
- Name a contact who can meet us at the agreed time

Advice
What the work involves, system by system
Offices, shops and commercial rooms
For bigger buildings, VRF systems link many indoor units to shared outdoor plant. Commercial and VRF systems are priced after a survey and the quote sets out the design.
Wall-mounted split systems
Bedrooms, offices and living spaces are where wall-mounted units are most often fitted. The unit goes where it spreads the air well and the filters are easy to reach, and away from where the air would blow straight onto people.
Why act early in Chertsey
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 most of the time heats too, so it works for you in winter as well. For a place like Chertsey, booking ahead lets us plan the visit properly.
Several rooms, units or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at, and you’ll get one fixed price.

Air conditioning in Chertsey: the local picture
About 30% of homes across Chertsey and its surrounding area have been built since 2000, according to Valuation Office Agency council tax records. Newer homes typically have cavity walls and loft space that make pipe runs easier, though some estates have planning conditions or covenants worth checking. Chertsey’s centre is no more than about a third of a mile from the Chertsey Conservation Area. Listed buildings are part of the picture here: about 78 within half a mile of the centre, such as Church of St Peter (grade II*). That matters for air conditioning: permitted development does not apply within the grounds of a listed building, in a conservation area the outdoor unit cannot go on a wall or roof facing a road, and a unit used only for cooling is not covered at all, so we check with the local planning authority (usually Runnymede council) where necessary.
Botleys Mansion (roughly 1.5 miles south-west) shows the area has its share of heritage. A listed home needs consent before an outdoor unit or pipework goes on. Around Church of St Peter, a quick check of the listing and conservation maps is part of planning any install.
Chertsey is about 6 miles north-east of Woking, in Surrey. We cover Chertsey for air conditioning, along with the rest of Surrey. Chertsey is one of 395 towns, villages and districts in Surrey we cover. For properties nearby, see our Guildford page (10 miles or so).
The closest recent job we can point to from Chertsey was on Queens Road, Weybridge (KT13), about 3 miles east: installing a full-house Mitsubishi Electric multi-split system covering five bedrooms, the study, the sitting room and the kitchen-living area: eight indoor units in total served by two outdoor units.

Chertsey: your questions answered
Is Chertsey within the area you cover?
Yes. Chertsey is within the area we cover across London and the South East. Send a few details and photos, and we reply the same working day.
Do you cover Chertsey for air conditioning?
We do: Chertsey falls inside our working area. Get in touch with the details and we reply the same working day.
Are you F-Gas certified?
AirCon Doctor is an F-Gas certified company, with NICEIC approval for electrical work and MCS certification for heat pumps. We’re also Checkatrade members.
Can I fit air conditioning or a heat pump myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That’s the law, not just our preference, and it also matters for the manufacturer’s warranty. We are happy to quote for the full job, supply to commissioning.
Where will you put the outdoor unit?
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.
Do you work for landlords and businesses?
Yes. From one rented home to commercial buildings, the approach is the same: a look first, a fixed-price quote and written records.
Is planning permission needed for the outdoor unit?
Not always. On a house, air-to-water heat pumps and, since 2025, air-to-air systems that heat as well as cool can be permitted development if they meet the conditions. Permission is more likely to come up for cooling-only units, listed buildings, flats and road-facing positions in conservation areas, and we tell you at the survey. This is general information, not legal advice.
