What air conditioning repair cannot fix
Not every problem is solved by air conditioning repair, and we’d rather say so up front. It doesn’t solve:
- A unit whose parts are no longer made (replacement may be the only option)
- A power cut or a fault on the incoming supply to the building (that’s for the network operator)
- A leak on an old R22 system
If in doubt, phone 07833 053749 or write to us at info@aircondoctor.co.uk and we will say what we think before booking.
What we work on in Friern Barnet
- VRF systems
- Heat pumps

Air conditioning repair in Friern Barnet, done properly
Age alone doesn’t decide whether a repair is worth it. A fan fault on an older unit can be worth fixing, while a compressor failure may tip the balance. You get an honest view based on the fault, the parts, the refrigerant and the room. The work covers ducted systems, VRF systems and wall-mounted split systems, and the jobs we see most are ice forming on the indoor unit or pipes and a suspected refrigerant leak.
In a London area like Friern Barnet, a lot of the systems we repair serve flats and small offices, with outdoor units on balconies, rear walls or flat roofs. Knowing where the outdoor unit sits, and how to get to it, helps us plan the repair.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we explain those terms on your quote. Terms differ from brand to brand, and we are happy to talk you through them.

How the job changes from property to property
Refrigerant leaks
A low refrigerant charge always means a leak. The leak is found and fixed, then the circuit is tested, evacuated and recharged, and the work is recorded in the F-Gas records.
Circuit boards and sensors
Circuit boards and temperature sensors control how the system runs. A failed sensor can make a unit stop, run oddly or show an error code, and boards can fail after a power surge or with age.

Air conditioning repairs in Friern Barnet: local notes
About 6 listed entries lie within half a mile of central Friern Barnet, Church of St John the Evangelist (grade II*) among them. That only matters for replacements, where a new outdoor unit on a protected building can need consent. The last census (2021) found about 50% of households live in flats. Balcony, roof or high wall? Knowing where a flat’s outdoor unit is helps us bring the right access kit. In London, access to outdoor units on roofs and balconies can need planning, so tell us how to reach yours.
Schools such as Holly Park Primary School can report a fault on the 24/7 line and have non-urgent work done out of term. For a home or office near New Southgate station, tell us the make, model and error code when you call, so we can plan the repair.

Questions from Friern Barnet
Can I get a fixed-price quote for air conditioning repair in Friern Barnet?
Start with a short message: the address, what you need and a picture or two. Simple jobs can be priced from pictures; otherwise we arrange a site survey and then give you a fixed-price quote.
Can you do air conditioning repair in Friern Barnet?
Yes, Friern Barnet is within the area we cover. Get in touch with the details and we reply the same working day.
Why is my air conditioning blowing warm air?
It could be a dirty filter, the wrong settings, a blocked outdoor unit, a sensor or board fault, or a refrigerant leak. Start by checking the filter and the mode, and if that does not fix it, call 07833 053749 or write to us at info@aircondoctor.co.uk.
Do you offer an emergency repair service?
Yes. We have a 24/7 emergency line for urgent breakdowns. Call 07833 053749 and tell us the make, the symptoms and any error code, and we will agree the next steps with you.
How long does the visit take?
Your quote will say how long we expect to be there. In most cases, it takes an hour or two to diagnose most faults, with the repair time depending on what we find.
Do you work on commercial properties?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size in Friern Barnet and across Greater London. Tell us who should receive the paperwork.
Can you repair an R22 air conditioning system?
Replacement is typically the better answer. R22 can’t be topped up with new gas, and parts for old models are scarce, so we’ll quote for a modern replacement and explain why.
What happens on the day
The visit goes in the diary at a time that works for you, and we let you know if plans need to move. When we arrive, we check the job against the survey or the pictures you sent. If something is different, we talk it through with you before carrying on. After that, it takes a single visit for many faults, while some repairs need a second visit once parts arrive. Managed buildings in London often need contractors booked in, and we can deal with the agent for a job in Friern Barnet.
- Diagnose: test the system until the cause is clear.
- 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.
- The treatment: the repair itself, with any leak found and fixed before recharging.
- Sign off: prove it works and record the visit.
Before we arrive
- Make sure we can reach the consumer unit or fuse board
- Name a contact who can meet us at the agreed time
- Mention any managing agent or landlord rules we need to follow
Getting a quote
Here’s what helps us quote: the address and the type of property, pictures of the rooms or units, the brand and model of anything already fitted and anything you’ve noticed, such as an error code or a noise. Then ring 07833 053749 or fill in the contact form.

What you can do yourself, and what needs us
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 us on 07833 053749 or fill in the contact form.
Don’t move, re-route or disconnect units or pipework yourself. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrics need care too. If you need something moved, we can quote for it.
A customer’s words
“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.”
