How we handle air conditioning servicing in Key's Green
People in Key's Green book a service for all sorts of reasons: a musty smell, weak cooling, water dripping indoors or simply because it’s been a while. Whatever the reason, the visit follows the same thorough checks. If you’re dealing with humming, rattling or squealing from the system and leak check records that need bringing up to date, we can sort it out.
Most systems around Key's Green need servicing once a year, best done before summer.
Think of the paperwork as the system’s health record: a dated account of the work and the readings we took. It makes the next visit quicker and any warranty question simpler, so keep it safe.

Signs you need air conditioning servicing in Key's Green
Outdoor units sit in the weather all year. Leaves, grime and plant growth gather on the fins and around the unit, which makes it harder for the unit to shed or pick up heat.
Common reasons people call us are:
- No service record for the last year or more
- Leak check records that need bringing up to date
- Iced-up coils or pipework
A service once a year suits most home systems, and some business systems need more.

Common questions in Key's Green
Do you cover Key's Green for air conditioning servicing?
Yes. We work across London and the South East from our base in East Grinstead, and Key's Green is part of that. Get in touch with the details and we reply the same working day.
Does my air con in Key's Green need a yearly service?
A yearly visit is right for most households. 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 work on systems someone else installed?
Yes. We work on systems fitted by other installers as well as our own, on all the main brands. Tell us the make and model and send any paperwork you have.
Why use an F-Gas certified company?
Companies working on equipment that contains F gas must be certified by an approved body, and the engineers need their own qualifications. It means the refrigerant in your system is handled legally.
Do you survey before quoting?
Yes, every time. We diagnose before we treat: the survey shows what’s needed, where things go and what access we need, and the quote is based on that.
Does my air conditioning need an F-gas leak check?
The rules are based on tCO2e, which comes from the refrigerant charge and its GWP. 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 under 10 tCO2e are exempt.
Which manufacturers do you install and repair?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For a new system, we suggest the make and model that suit the property and explain why.
System by system
Condensate drains and pumps
Cooling pulls moisture out of the air, and that water has to drain away. The tray is cleaned and the pipe flushed through so it flows properly.
Fans and electrics
Controls and remote handsets are tested in each mode so you know it does what you ask.

What happens on the day
Think of the visit in three stages: diagnose, treat and sign off. First comes a careful look at the system or the space, then the work itself, and finally we test, record and explain. The middle part takes longest, and that takes around an hour for one indoor and one outdoor unit, with extra time for each additional indoor unit. Photos of the existing unit help with repairs and servicing in Key's Green.
- We book a time that suits you and confirm the price.
- Before any cleaning, the system is run so we can see how it behaves.
- Filters, coils, fans and drains are cleaned and cleared.
- We check the wiring, controls and refrigerant circuit, and leak check systems that need it.
- It’s run once more to confirm all is well, and the record is left with you.
Before we arrive
- Clear the space around the indoor unit, or where it will go
- Let us know if the building has a permit or sign-in process
- Dig out any previous service or F-Gas records

Photos are enough for some jobs; others need a visit first. Multi-room systems, commercial buildings and anything with a long or hidden pipe route are normally surveyed first. Either way, you get a fixed price before any work is booked.
Advice
Keeping systems in Key's Green running
Census 2021 figures found about 74% of households in detached or semi-detached houses. Tell us where your outdoor unit is and how to reach it, so we can plan the visit. The middle of Key's Green is part of a conservation area. On the National Heritage List, around 9 entries fall within 0.5 miles of the middle of Key's Green; The Blue Boys Inn (grade II) is one. Day-to-day work on an existing system is not affected; a replacement outdoor unit on a protected building might be.
Dust on the filters and coil makes the system work harder for the same result.

Before you call an engineer
Write down what you notice: an error code, a new noise, a drip, a smell or a change in how well the system heats or cools. It helps us diagnose quickly, and a photo of the display helps even more.
Some faults have simple causes you can check first: check the mode, the set temperature, the remote’s batteries and the breaker. If the breaker trips a second time, leave it off and ring 07833 053749 or write to us at info@aircondoctor.co.uk.
