Air conditioning repair in Radlett, Hertfordshire

What you can do yourself, and what needs us
Before you call us about a fault, a few checks can save a visit: check the mode, the set temperature, the remote’s batteries and the breaker. If the breaker trips a second time, leave it off and call us on 07833 053749.
There are a few things you can safely do yourself: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Anything inside the units, the electrics and the refrigerant is engineer’s work.
About our air conditioning repair in Radlett
Any repair we carry out in Radlett starts the same way: the engineer reads the fault codes and checks the electrics, the airflow, the condensate drain and the refrigerant pressures and temperatures. After that, you get a plain explanation and a fixed price for the repair. If you are dealing with an error code or flashing light on the unit and a unit that has lost refrigerant, we can sort it out.
In a place like Radlett, repairs are normally for home systems and the odd shop or office. We plan the visit from what you tell us about the fault, so a description and a photo of any error code really help.
Whatever the visit, you get a written record: commissioning details for an installation, a fault and repair note for a repair, or a record of the service. File it with the manual so it’s to hand next time.

Radlett: your questions answered
Will you come out to Radlett?
We do. Villages and hamlets get the same service as the bigger towns. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Do you cover Radlett for emergency air conditioning repairs?
Yes: ring the emergency line, day or night, from anywhere in Radlett. Tell us the make, model and any error code when you call; repair call-outs start from £75 + VAT.
Do you provide F-Gas records?
Yes. You get a written record of every visit, and any work on the refrigerant circuit goes in the F-Gas records. Keep them with the manual and the warranty documents.
What warranty do I get?
The manufacturer provides it, on its own terms. Some terms depend on regular servicing by a qualified engineer, so keep your service records.
How do you keep the place clean during the work?
Floors and furniture near the work are covered with dust sheets before any work starts, and the area is kept tidy throughout. At the end, we clear up and show you what we have done.
My system uses R22. Can it be repaired?
R22 is an ozone-depleting refrigerant, and new R22 can’t be used for servicing. A fault that does not involve the refrigerant may still be repairable, depending on parts, but a refrigerant leak typically means replacement. We’ll set out the options and quote for a replacement where it makes sense.
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. Tell us the make and model and we’ll take it from there.
How the visit works
On the day, we arrive at the time agreed with you and check the plan with you first. Floors and furniture near the work are covered with dust sheets, and the electrics are made safe before any panel comes off. On site, it takes an hour or two to diagnose most faults, with the repair time depending on what we find. Let us know how to reach the outside wall or outdoor unit at your property near Radlett.
- Diagnosis comes first: codes, electrics, airflow, drain and refrigerant.
- Next, a plain explanation and a fixed price.
- 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.
How to prepare
- Let us know if the units are on a roof, a high wall or in a locked area
- Make sure someone can let us in at the agreed time
- Mention any managing agent or landlord rules we need to follow

Advice
System by system
Multi-split systems
On a multi-split, one outdoor unit serves several indoor units, so a fault outside can affect every room, while a fault inside may affect only one. That shapes the diagnosis and the repair.
Ducted and cassette systems
If water is coming through the ceiling, switch the unit off and call us. The cause is normally the condensate pump, a blocked drain or a tray that’s overflowing, and we check all three.
From one of our customers
“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
