Common questions in Langley Bottom
Will you come out to Langley Bottom?
We do. Villages and hamlets get the same service as the bigger towns. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
How often should air conditioning in Langley Bottom be serviced?
Once a year suits most home systems. Larger systems holding 5 tonnes CO2 equivalent or more also need a leak check at least every 12 months under the F-gas rules.
Do you do service contracts for air con?
Yes. A contract sets out how often we visit and what each visit covers, at a fixed price agreed with your quote. It suits anyone who would rather not track service dates.
Is an F-gas leak check a legal requirement for my system?
It depends on the system’s tonnes of CO2 equivalent (tCO2e). At 5 to under 50 tCO2e, it’s at least every 12 months; at 50 to under 500 tCO2e, every 6 months. Hermetically sealed systems holding less than 10 tCO2e do not need them.
Do you offer emergency call-outs?
Yes. For anything urgent, such as a system failing in a server room or water leaking from a unit, ring our 24/7 line and we’ll agree what happens next.
Will you regas my air conditioning on a service?
We check refrigerant performance on every service, but adding gas is separate work. If it’s low, a leak repair comes first and the regas follows, priced before we start.
Do you look at the job first?
Yes. We always look before we price, either on a site survey or from pictures and details for simple jobs. Then you get a fixed-price quote.
Air conditioning servicing for homes and businesses in Langley Bottom
Air conditioning pulls room air through a filter and across a cold coil many times an hour. Whatever is in the air, from dust to pet hair, collects on the filter and coil. Servicing removes it, letting air pass through the unit properly and the condensate drain away. The work covers multi-split systems, air-to-air heat pumps and ducted systems, and common reasons people get in touch are an unpleasant odour when the system runs and no service record for the last year or more.
We plan the trip to Langley Bottom and can service more than one unit in one visit.
We’re an F-Gas certified company, NICEIC approved for electrical work, with MCS certification for heat pumps and Checkatrade membership. Our engineers hold the F-gas qualifications needed to work on refrigerant.

What else we do in Langley Bottom
Aftercare tips
A little care keeps the system in better shape. We recommend:
- Keep the filters clean between visits
- Read the warranty conditions for your brand
- Keep the drain outlet clear
A maintenance contract takes the scheduling off your hands. We agree the visits and the cost up front so you don’t have to remember.
The single most useful thing you can do is keep the filters clean. Most indoor units have filters you can slide out and rinse, and the manual shows how.
How the job changes from property to property
Wall-mounted, ducted and cassette units
With a ducted system, the unit is hidden above the ceiling. Servicing means reaching the unit through an access hatch, so let us know where the hatch is.
Maintenance contracts
We tailor the schedule to how hard the system works, rather than a one-size plan.
Pricing air conditioning servicing in Langley Bottom
Before we fix a price, we need to know a few things. We check:
- How many units are involved
- What kind of system it is
- The brand, model and parts involved
One room or a whole building, we price it on the same basis: the work involved, the access and the equipment. You’ll have a fixed price before any work starts, with VAT shown clearly.
Before you get in touch
Simple jobs can often be priced from photos and some basics. Useful things to send:
- The address and the type of property
- A short video of any fault, such as a noise or a flashing light
- The paperwork from the last service, if you have it
Getting a quote is straightforward. Send a few details and pictures, and we reply the same working day. If we need to see the property first, we book a survey at a time that works for you.
Servicing in Langley Bottom: local notes
Listed buildings are part of the picture here: about 8 within half a mile of the centre, such as Dyes Farmhouse (grade II*). Swapping an outdoor unit on a listed building or in a conservation area may need consent, so we’ll flag it if a replacement is needed. About 40% of households live in terraced houses, according to the 2021 Census. With a terrace, access to the rear for the outdoor unit is the main thing to tell us.
Most homes book one service a year; busy offices and shops may want more. Site managers at schools like The Thomas Alleyne School can have the site’s units serviced during a holiday.

How it works
Protection comes first: dust sheets over floors and furniture near the work, and we ask before moving anything. Then the electrics are made safe and the work begins. It takes an hour or so for a single wall-mounted unit, longer for a multi-split system, and we clear up before we go. Photos of the room and the outside of the property help us plan a visit to Langley Bottom.
- When you book, we ask what make it is, how many rooms it serves and whether anything seems wrong.
- The engineer switches the system on and checks how it behaves before taking anything apart.
- Dust and grime come off the filters and coils, and the drain is flushed so water runs away properly.
- Electrical connections, controls and refrigerant performance are checked, with an F-gas leak check where the system requires one.
- Before leaving, the engineer writes up the visit and talks you through anything worth knowing.
How to prepare
- Let us know where we can park and unload
- Make sure we can reach the consumer unit or fuse board
- Make sure someone can let us in at the agreed time
