Air conditioning repair in Hendon, Greater London
We cover Hendon for fault finding and repair for split, multi-split, ducted, cassette and VRF air conditioning, whatever the brand. Diagnosis first, a fixed price and proper paperwork when we finish.
- A unit that won’t start
- Drips from the indoor unit
- A unit that has lost refrigerant
What happens on the day
Each visit follows the same order: agree the plan on site, protect the area, do the work, check the system and talk you through it. The visit itself takes an hour or two to diagnose most faults, with the repair time depending on what we find. Let us know who controls access to the building in Hendon, as that saves time on the day.
- First the diagnosis: fault codes read, electrics and airflow checked, drain and refrigerant tested.
- Then the prescription: what’s wrong and what it will cost to put right.
- If the repair isn’t worth doing, we say so and explain the options.
- Then the fix, with leaks repaired before any refrigerant is added.
- The sign-off: the system tested in operation and the work recorded.
How to prepare
- Mention any managing agent or landlord rules we need to follow
- Have the make and model of any existing unit to hand
- Let us know where we can park and unload

Air conditioning repair in Hendon, done properly
Not sure whether it’s worth calling an engineer? Check the filter, the mode, the set temperature and the remote’s batteries first, and if that doesn’t fix it, phone 07833 053749 or email us. We reply to enquiries the same working day. If the problem is a unit blowing warm air and a unit that barely blows any air, we can help.
In a managed building in Hendon, the repair may need booking through the agent or building manager, so tell us who controls access. Outdoor units on roofs may need a key, a permit or an escort, and we plan for that before we arrive.
We’re an F-Gas certified company, NICEIC approved for electrical work, with MCS certification for heat pumps and Checkatrade membership. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

In flats, outdoor units are often on balconies, roofs or high walls, so tell us how we reach yours. London repairs often depend on reaching the outdoor unit, so access details help us plan.

Pricing air conditioning repair in Hendon
Our prices page gives typical ranges, but every job is priced on its own. What we look at:
- What we find on the survey or diagnosis
- Whether it’s a simple split or a larger system
- Whether it’s a one-off job or part of a maintenance contract
What you pay reflects the actual work. That is why every job is looked at first, and the price is agreed before any work starts.
Helping us quote
Photos and a few facts are often enough to price a simple job. Useful things to send:
- The make and model of the system, from the label
- The postcode and whether it’s a home, flat or business
- The outside wall, roof or yard where the outdoor unit sits or would go
Photos are enough for some jobs; others need a visit first. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, the quote is fixed before anything goes ahead.
Different systems, different jobs
Wall-mounted split systems
Wall-mounted splits are the systems we repair most often. Drains, coils, fans, sensors and leaks account for many of the faults, and most are diagnosed on the first visit.
Ducted and cassette systems
Ducted units and cassettes sit above the ceiling, so access matters. Condensate pumps are common on both, and a failed pump is a frequent cause of water leaks.
Managing agents and facilities teams in Hendon
Where a tenant occupies the property but the landlord owns the system, it’s worth checking the agreement for who looks after the system. We can quote either party, and the paperwork can go to both.
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’re happy to deal with whoever it is.
FAQs for Hendon
Can you do air conditioning repair in Hendon?
Yes. We work across London and the South East from our base in East Grinstead, and Hendon is part of that. Get in touch with the details and we reply the same working day.
How do I get a quote for air conditioning repair in Hendon?
Start with a short message: the address, what you need and a picture or two. Where pictures aren’t enough, a survey comes first and the fixed-price quote follows.
Can you repair an R22 air conditioning system?
R22 is an ozone-depleting refrigerant, and new R22 can’t be used for servicing. Some non-refrigerant faults can be repaired if parts are available, but a refrigerant leak usually means replacement. We will set out the options and quote for a replacement where it makes sense.
Do I need to service the system to keep the warranty?
It can, for some brands. Read the manufacturer’s terms, or send us the make and model and we’ll explain them, and book the service at the interval they recommend.
How long does the work take?
We will confirm the time with your quote. As a guide, the work takes anything from an hour or so to a full day, depending on the fault and the parts.
Do you work on commercial properties?
Yes. From one rented home to commercial buildings, we work the same way: a look first, a fixed-price quote and written records.
Which brands do you work with?
We work with the leading brands, 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.

From one of our customers
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
