Air conditioning repair in Lye Green, done properly
Not sure whether it’s worth calling an engineer? A quick check of the filter, settings and remote can rule out the simple causes, and if that doesn’t fix it, give us a ring on 07833 053749, or email if that’s easier. You’ll hear back from us the same working day. We are often asked to deal with a system that runs but doesn’t cool the room and a fault code on the display, on multi-split systems, ceiling cassettes and heat pumps.
Around Lye Green, outdoor units often sit close to gardens and hedges, so leaves, seeds and cobwebs on the coil are worth checking first.
Refrigerant work is written up in the F-Gas records: the work carried out, the refrigerant involved and the quantities. Keep the records with the manual and the warranty documents, ready for the next service or a warranty query.

Air conditioning repair around Lye Green

Day-to-day work on an existing system is not affected; a replacement outdoor unit on a protected building might be. About 42% of homes in and around Lye Green date from 1945 to 1972, according to the Valuation Office Agency’s council tax figures. Wall bracket, ground pad or flat roof: knowing where the outdoor unit is saves time on the day.

Lye Green questions
Will you come out to Lye Green?
Yes. Lye Green is within the area we cover across London and the South East. A few photos and the postcode are enough to get things started.
Do you cover Lye Green for emergency air conditioning repairs?
The emergency line is open around the clock, and Lye Green is one of the places it covers. Have the make, model and error code ready, and we will talk you through what happens next.
Do you survey before quoting?
Yes. For simple jobs, photos and a few details can be enough, while bigger systems and repairs that need testing get a visit.
Do you work on commercial properties?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size across London and the South East. Let us know who the records should go to.
Which brands do you work with?
We install and work on the leading makes, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.
Why is my air conditioning icing up?
It typically points to poor airflow or a refrigerant leak. Blocked filters, a failing fan or a leak are the common causes. Turn it off, let the ice melt and ring 07833 053749 or send an email.
Can you set up regular servicing?
Yes. Maintenance contracts are part of what we do, set at the interval the system and the manufacturer’s terms need. Each visit is recorded, with F-Gas records where refrigerant work is involved.
What we do, step by step
The visit goes in the diary at a time that works for you, and we let you know if plans need to move. On arrival, the engineer compares the job with the survey, your pictures or the details you gave us. Anything unexpected is raised with you before we go further. From there, the work takes anything from an hour or so to a full day, depending on the fault and the parts. Visits to Lye Green are agreed with you in advance and planned so the job can be finished in one trip where possible.
- Diagnosis comes first: codes, electrics, airflow, drain and refrigerant.
- Prescribe: tell you the cause and the fixed cost of the cure.
- If the repair is not worth doing, we say so and explain the options.
- Treat: carry out the repair, sealing any leak before refrigerant goes back in.
- Sign off: prove it works and record the visit.
Before we arrive
- Tell us about any building rules, permits or sign-in
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Move furniture away from the wall where we’ll be working

Photos are the fastest route to a quote: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Add the address and what you’d like done, and many jobs can be priced from that.

Rented and managed buildings
Under the GB F-gas rules, responsibility for leak checks is shared between whoever operates the equipment and the engineers who work on it. In a let or managed building, it’s worth agreeing who that operator is, and we can work for either side.
We regularly work with managing agents. Tell us the property, the work and the access arrangements, and we will send a fixed-price quote.
When it’s something else
We will always give you a straight diagnosis, so here’s what air conditioning repair won’t do:
- An R22 system that has lost its refrigerant
- A system that was undersized for the room in the first place (that needs a bigger system, not a repair)
- A discontinued model with no parts available
If you are not sure, just phone 07833 053749 or write to us at info@aircondoctor.co.uk and we’ll give you a straight answer.
Parts of the system we cover
- Heat pumps
- Ceiling cassettes

Common problems we fix in Lye Green
Rattles, buzzes and grinding sounds tend to be mechanical. Fan bearings, loose casing, leaves or debris in the outdoor unit and vibrating pipework are typical causes and some point to a compressor problem.
It’s time to call us if you’re dealing with:
- A system that keeps cutting out
- Frost on the pipework
- An error code or flashing light on the unit
If the display shows a code, write it down: it helps narrow down the fault.
