Air con installers in Netherne on-the-Hill
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi are among the brands we fit. The survey ends with a recommendation and the reasons for it, and the manufacturer’s warranty terms are set out on your quote. Modern air conditioning heats as well as cools: in heating mode they work as an air-to-air heat pump, which is why many owners use theirs all year.
Where the outdoor unit goes decides how quiet and tidy the job is: we balance airflow, noise, the pipe run and access for future servicing.
Across London, and in Netherne on-the-Hill too, a lot of air conditioning goes into flats and terraces rather than detached houses. So the first questions are where the outdoor unit can sit, how the pipes get to it and whose permission is needed. In a flat, the lease and the freeholder normally come into it, and we can give you the details they’ll ask for.
Any work on the refrigerant circuit is recorded: the work carried out, the refrigerant involved and the quantities. Keep the records with the manual and the warranty documents, as a manufacturer or a future engineer may ask to see them.

Air conditioning around Netherne on-the-Hill
The Valuation Office Agency’s council tax figures date about 47% of homes in the Netherne on-the-Hill area to the post-war years, 1945 to 1972, and Census 2021 figures found about 76% of households in detached or semi-detached houses. Homes of that age typically have cavity or solid brick walls, and we check which before planning the pipe route. Detached and semi-detached houses usually have space for the outdoor unit, and several rooms can share one on a multi-split. London installs often hinge on outside space, the lease and access to the building.
A loft bedroom or a glazed extension is often the room that prompts the first call. Homes near Church of St Margaret are a good example of where we look up the heritage status of the building before fixing anything to it.

How it works
Protection comes first: dust sheets over floors and furniture near the work and nothing is moved without asking you. Then the electrics are made safe and the work begins. The work on site takes a day or more, depending on the number of rooms, the pipe routes and the access, and we tidy up before we leave. Photos of the room and where the outdoor unit could go let us plan most of a visit to Netherne on-the-Hill in advance.
- First the diagnosis: a survey of the rooms, the walls, the outside and the electrics.
- Next, a recommendation for each room and a fixed price.
- Then the work: units up, pipes and drain run, and a new circuit where needed.
- Testing: the circuit is pressure tested and evacuated before the refrigerant is released.
- The sign-off: commissioning, a walk through the controls, and the F-Gas records and warranty details.
Getting ready for the visit
- Arrange for someone to be there to let us in
- Let us know where we can park and unload
- Keep pets out of the rooms we’re working in

Advice
Keeping the system healthy
To keep the system working properly:
- Have the system serviced once a year
- Use moderate settings for comfort and economy
- File the paperwork with the manual
The handover includes the records you need: F-Gas records, commissioning details and the manufacturer’s warranty terms. File them together, because the manufacturer or a future engineer may ask to see them.
Set it and leave it. A moderate set temperature cools the room just as well as the lowest one, without the waste, and close windows and doors while it’s cooling.
How the job changes from property to property
Pipework and condensate drains
Air conditioning takes moisture out of the air when it cools, and the condensate drain carries it away. If gravity won’t do it, a condensate pump is fitted, and we plan that on the survey.
Outdoor unit positions
Outdoor units are fitted on wall brackets, at ground level or on a flat roof, depending on the property and the pipe route. It needs space around it to breathe and for an engineer to work on it.
Why act early in Netherne on-the-Hill
The outdoor unit’s position is worth getting right first time. Placing it well keeps noise away from bedrooms and boundaries and makes servicing easier, and it can make a difference to planning. It’s agreed on the survey, not on the day. Getting the work done in Netherne on-the-Hill before summer avoids the busiest weeks.
Putting several jobs into one visit often makes better use of the time. Tell us about everything you’d like looked at and we will price it together.

Common questions in Netherne on-the-Hill
Is planning permission needed for air conditioning in Netherne on-the-Hill?
That depends on the building and where the outdoor unit goes. The Netherne-on-the-Hill Conservation Area takes in the middle of Netherne on-the-Hill. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and is not used only for cooling. Listed buildings still need consent, and in a conservation area a road-facing wall or roof is not allowed under those rules. If there’s any doubt, we ask the planning department at Reigate and Banstead council, usually the authority for Netherne on-the-Hill.
Is Netherne on-the-Hill in your area for air conditioning?
Yes. Netherne on-the-Hill is one of the places we cover. To start, call 07833 053749 or email us with a few photos.
Can you look at a system you didn’t fit?
Yes. Systems fitted by other companies are fine from all the leading brands. Send us the make and model, and any records you have.
What accreditations do you have?
As the law requires for refrigerant work, we are an F-Gas certified company. We are also NICEIC approved, MCS certified for heat pumps and Checkatrade members.
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 units need a void or loft, and cassettes need a suspended ceiling, which we check on the survey.
Why use an F-Gas certified company?
F-Gas certification shows a company is approved to work on equipment containing fluorinated gases, such as the refrigerant in air conditioning and heat pumps. That is not optional: it’s required by law, and AirCon Doctor is certified.
Will I get records for the system?
Yes. You get a written record of each visit, including F-Gas records for any refrigerant work. Keep them with the manual and the warranty documents.
