Already have air conditioning? We'll keep it running.
If you've got air conditioning but no one services it — your original installer has moved on, or it's simply been forgotten — Chillston services and repairs any make across the Chilterns, and keeps your manufacturer warranty valid.
Most systems out here have never been serviced
Air conditioning needs servicing once a year — nearly every manufacturer makes warranty cover conditional on it, carried out by an F-Gas registered engineer and documented. Very few people are ever told this. Thousands of systems around the Chilterns were fitted by installers who have since moved on, gone quiet, or never offered servicing in the first place. An unserviced system runs less efficiently, costs more to run, and is far likelier to fail on the hottest day of the year.
It is easily put right
We can put it right. A Chillston Health Check tells you exactly what condition your system is in, restores it to good working order, and — if you'd like — makes you a Chillston Care member, so the Health Check happens every year without you thinking about it and your warranty stays valid from here on.
Servicing for systems we didn't fit
One-off health check
A full inspection and service of your existing system, whatever the make. We tell you honestly what condition it's in and what (if anything) it needs.
Repairs
Not working as it should? We diagnose and fix faults on most makes — refrigerant, drainage, electrical or performance issues — with a clear price before we start.

What a proper service includes
Plenty of "services" amount to a filter wipe and an invoice. Here is everything we do, every time — and we leave you a written record of it for your warranty file.
- Performance check in both modes — temperatures and pressures measured and recorded, not eyeballed
- Filters cleaned or replaced — the single biggest cause of lost efficiency
- Indoor coil and blower cleaned — where the smell comes from when a system has been neglected
- Condensate tray and drain cleared — the most common cause of water appearing on a wall
- Outdoor unit cleaned, coil checked, clearances confirmed
- Electrical connections checked and tightened — loose terminals are a genuine fire risk
- Refrigerant charge verified and leak-checked to F-Gas requirements
- Written report and warranty record updated, so your cover stays valid and provable
And the things we won't do
Some of this will cost us work. We'd still rather tell you than take your money.
- We won't just "top up the gas"
- Refrigerant isn't consumed like fuel. If your system is low, it's leaking — and under F-Gas regulations the leak has to be found and repaired, not simply refilled. Anyone offering to top you up and drive away is selling you the same problem again in four months.
- We won't try to keep an R22 system going
- R22 is a banned refrigerant. It can't legally be topped up or replaced, so no amount of money makes that system a long-term prospect. If yours is R22, we'll tell you honestly and price a replacement instead.
- We won't sign off someone else's dangerous work
- If we find an installation that isn't safe, we'll document it, show you the photographs and explain the options. What we won't do is service it and imply it's fine.
- We won't repair what isn't worth repairing
- If your system is twelve years old and the board has failed, we'll say so rather than quote you four hundred pounds to buy another eighteen months.
What people ask us about servicing
How often does air conditioning need servicing?
Once a year. It isn't only about performance: most manufacturer warranties — often up to seven years — are only valid if the system has been serviced annually by an F-Gas registered engineer. Miss a year and you can lose cover you've already paid for.
My original installer has disappeared. Can you take my system on?
Yes, and it's a large part of what we do. We service systems we didn't fit, whatever the brand, and we'll give you an honest assessment of its condition on the first visit — including anything the original installation got wrong.
My system isn't cooling well. Can you just top up the gas?
No, and nobody reputable should. Refrigerant isn't consumed, so if the level is low there is a leak. Under F-Gas regulations that leak must be found and repaired rather than simply refilled. We'll pressure-test, locate it, and quote you the actual repair.
Do you service brands you don't install?
Yes. Daikin, Mitsubishi, Panasonic, Bosch, LG, Samsung and most others. If we come across something genuinely unusual we'll say so before booking rather than after arriving.
What does it cost?
A one-off Health Check is £175 for a single system, plus £50 for each additional indoor unit on the same visit. Membership is £12 a month for the first indoor unit and £3 for each one after it — so £15 for two, £18 for three. It is cheaper than paying as you go at every size, because we service each town in one go rather than making a special trip, and it also includes a call-out each year, priority when we're busiest, and parts and labour at member rates.
What if you find something wrong?
We tell you immediately, show you, and quote it separately. We never carry out chargeable repairs on the day without asking you first.
You won't have to remember
Air conditioning needs servicing once a year. That's not our rule — every manufacturer makes warranty cover conditional on it.
You can book that yourself each year, or become a member and never think about it again:
- When we're busiest, members come first
- We contact you when the Health Check is due — not the other way round
- One call-out a year, no charge to attend
- Price fixed for your first 12 months, then 30 days’ notice of any change
A one-off Health Check is £175, and £50 for each additional unit on the same visit. Membership is £144 a year for one unit, includes a call-out, and we keep the warranty paperwork for you. Whatever size the system, membership costs less than booking the same servicing visit by visit.
