Air conditioning repair in Greenford
When air conditioning stops cooling, leaks water or shows an error code, the symptom rarely tells you the cause. A unit blowing warm air might have a blocked filter, a failed sensor, a fault on the circuit board or a refrigerant leak, so we diagnose before we repair. Typical jobs include an error code or flashing light on the unit and drips from the indoor unit, on multi-split systems, wall-mounted split systems and ceiling cassettes.
London systems in Greenford often run long hours in summer, which is when weak cooling, leaks and error codes tend to appear. A photo of the error code and the unit’s label helps us arrive with the right parts in mind.
Some manufacturers make regular servicing by a qualified engineer a condition of their warranty. Where yours does, a regular service with us keeps that side in order and each visit is recorded.

- New noises from the system
- Poor airflow even with clean filters

What does F-Gas certified mean?
Anyone installing, repairing or servicing the refrigerant side must be qualified, and their company certified. Ask to see proof before you book anyone and we’ll gladly show you ours.
Which manufacturers do you install and repair?
We install and work on the leading makes, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.

Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size in Greenford and across Greater London. Let us know who the records should go to.
Do you protect the property while you work?
We start with protection: dust sheets over floors and anything close to the work. Any drilling is agreed with you first, and we clear up the dust and offcuts before we leave.
What warranty do I get?
Warranty comes from the manufacturer and depends on the brand and product. For instance, Daikin’s standard warranty on split air conditioning is 2 years, and we explain the terms for whichever brand you choose.
How it works
Every visit follows the same order: check the plan with you, protect the area, do the work, check the system and explain it all to you. On site, the work takes an hour or two to diagnose most faults, with the repair time depending on what we find. Send us a few phone pictures and we can often price a straightforward job in Greenford before visiting.
- We start with what the unit is doing, the make and any code.
- The engineer diagnoses the fault on site, testing rather than guessing.
- We explain the cause in plain English and give you a fixed price.
- Once you’re happy, the repair is done and any refrigerant work recorded.
- We test the system in operation and leave you a note of the fault and the fix.
Getting ready for the visit
- Have the make and model of any existing unit to hand
- Plan for pets to be kept clear during the visit
- Tell us about access, such as roof hatches, high walls or locked plant areas
How to get a quote
VAT is set out clearly on every quote, and the rate that applies to your job is stated. VAT can differ between homes and businesses and between kinds of work, so we confirm it on the quote. To get one, ring us on 07833 053749 or drop us a line.

Owner checks or an engineer?
Before you call us about a fault, a few checks can save a visit: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If a breaker trips again after you reset it, leave it off and give us a ring on 07833 053749 or send an email.
Good habits make our visits easier, not unnecessary. Clean filters and a clear outdoor unit help the system run as it should, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.
