Air conditioning in Westerham
Air conditioning in Westerham, from the Green to the newer estates
Apex fits and services heat-and-cool air conditioning in Westerham, about 14 miles from our Dartford base. Whether you live in an old house near the Green or a newer home north of the A25, Olly surveys it himself and gives you a fixed written quote.

Air con in the old centre and north of the A25
For air conditioning, Westerham splits neatly in two. The old centre is a conservation area of about 36 hectares with around 100 listed buildings, many of them packed close together. There, the outdoor unit needs a rear or side position away from the street, and a listed house needs listed building consent from Sevenoaks District Council first.
North of the A25, most homes are twentieth- and twenty-first-century houses with gardens. These normally suit a standard wall-mounted split on a rear wall or garden pad, usually under permitted development as long as the unit passes the 37 dB(A) noise check. Our guide to planning rules for air con explains both cases.
Offices and workshops on the old station site
The small industrial and office units on the old railway station site often have flat roofs or yards that take an outdoor unit easily. A workshop with machinery or a server cupboard can need cooling most of the year, and an office can use the same system for heating in winter.
Commercial units normally need planning permission for outdoor plant, which we flag at the survey. See air conditioning for businesses.
Shops and cafés in the old centre are harder, because most sit in listed or historic buildings close to the street. A rear yard is usually the only realistic place for an outdoor unit, and we check access to it at the survey.

Air con repairs and servicing in Westerham
If you already have air conditioning that has stopped cooling, drips water indoors or shows an error code, we can find the cause. Water from the indoor unit is often a blocked condensate drain or a dirty coil.
Weak cooling can mean a refrigerant leak, which we trace and fix before recharging. Our air con repair page lists the common faults, and a yearly service helps stop them coming back.

Crockham Hill, Brasted and villages around Westerham
From Westerham we cover Crockham Hill, Brasted, Sundridge, Tatsfield, Biggin Hill and, over the Surrey border, Oxted. The countryside around the town is Green Belt and part of the Kent Downs National Landscape, which can limit where an outdoor unit goes on a rural house.
We check this before quoting. On a farmhouse or a house with a big garden, the outdoor unit can often sit on a ground pad well away from the house, with the pipes run underground, so it is neither seen nor heard from the bedrooms.

Olly was very professional in listening to my requirements and giving advice. On the day of installation Olly and Andy carried out the work in a professional, timely and clean manner.

Questions
Air conditioning in Westerham: questions
Can I have air conditioning in a listed building in Westerham?
Often, yes, with listed building consent from Sevenoaks District Council. The council will want to see that the outdoor unit is out of sight and that drilling does little harm to the historic fabric. We survey first, find a rear or side position and a careful pipe route, and give you the details your application needs.
Why is my air con leaking water?
Most often the condensate drain is blocked, so water that the unit pulls out of the air overflows from the indoor unit. A very dirty filter or coil can cause ice to form and then drip as it melts. Turn the system off and book a repair. We clear the drain, clean the coil and check the refrigerant.
Can air con heat my Westerham office in winter too?
Yes. The systems we fit are heat-and-cool, so the same units that cool the office in summer heat it efficiently in winter. For an office or workshop on the old station site, that can replace electric panel heaters. Systems over 12kW in total also need a TM44 energy inspection, which we can explain at the survey.
Do you cover Biggin Hill, Brasted and Oxted?
Yes. Around Westerham we cover Crockham Hill, Brasted, Sundridge, Tatsfield, Biggin Hill and Oxted. The countryside rules there can affect where the outdoor unit goes, so we check before quoting. Send a photo on WhatsApp and Olly will arrange a free survey.
