5 Best Aircon Servicing Pros in London to Keep Your Cool
I rely on HVAC companies to keep my home comfy, especially when a London heatwave turns the bedroom into a sauna. When the aircon starts wheezing, I’d rather call a pro than sleep beside the freezer!
Regular servicing helps catch problems early and keeps the cool air coming. It’s handy for offices and shops too, where a stuffy room can make a long day feel even longer.
So I’ve looked into local companies offering the best aircon servicing in London. Here are some worth considering when your system needs a little attention.
How much does aircon servicing cost in London?
A standard single-unit service typically costs £70–£120. A planned preventative maintenance plan starts at £40 per month.
Engineer labour runs £30–£100 per hour. A weekday call-out costs £130–£180, while an emergency or weekend visit costs £170–£220.
Refrigerant regassing costs £70–£120, plus the cost of the gas. A deep chemical coil clean costs £150–£220. Replacement parts can add £100–£1,000 or more to the bill.
1. London Air Con
Address: S201 Garden Studios, 71-75 Shelton St
Contact: +44 (0) 800 208 6722; [email protected]
Hours: Contact to schedule service
When my aircon starts making more noise than cool air, I want someone who can find the problem without the guesswork.
London Air Con services and repairs systems in homes and businesses across the capital, so it’s worth considering whether you’ve got one wall unit or a bigger setup.
Its engineers inspect, clean and test key components during maintenance visits. That’s the sort of attention I’d want before a small fault turns a warm bedroom into a sleepless one.
The company handles installations and repairs as well as routine servicing. I like having one team to call if a check-up turns into a conversation about fixing or replacing the unit.
The only catch for homeowners is that residential work shares the spotlight with large commercial projects.
If you’d feel more comfortable with a home-only specialist, you might prefer a smaller outfit.

We were so impressed with the speed of response through to quotation
We were so impressed with the speed of response through to quotation.
We have considered having Air conditioning installed for some time but were put off by the ugly external units.
John is obviously experienced in his field & designed our system so that the external units are discreetly positioned either side of the property & not visible from the road or courtyard.
The inside units are small & silent but powerful enough to chill each room within minutes.

Highly recommended
Really professional service. Had AC fitted to two bedrooms for cooling and heating. The engineer (John) explained everything about the installation from start to finish, and did exactly what he said, when he said he would do it. Tidy, friendly and helpful. Can’t ask for much more. Highly recommended.

2. Debonair Cooling
Address: Office 105, Atlas Business Centre, Oxgate Lane
Contact: 020 3960 2555; [email protected]
Hours: Daily: 6 AM – 8 PM
When my aircon starts dripping or rattling, I’d like an engineer who knows where to look before my living room turns into a greenhouse.
Luckily, Debonair Cooling services home units and larger commercial systems, including wall-mounted splits and more complex VRV setups.
Its REFCOM-certified engineers inspect, clean and test key components during maintenance visits. I like that they offer a one-off service for a check-up, as well as annual contracts for people who want regular care.
They’re open from 6 AM to 8 PM every day, which gives me more room to fit a booking around work. Their Daikin D1+ installer status is useful if servicing leads to a conversation about replacing an ageing unit.
The catch is that maintenance-contract clients get priority response. If I only wanted a one-off visit, I’d check the available appointment dates before relying on them for an urgent fix.

Great service from start to finish
Great service from start to finish, we are out of the usual area so there was a lot of travel involved for the engineers. We had a multi split unit fitted and three air conditioners inside the house. The job was 4 days but I think a lot of that was due to travel time.
There was no mess and barely any noise. I expected lots of disruption so that was a pleasant surprise. All the pipe work/wiring is very well hidden externally along the roofline and inside there is no evidence of any works.

I would definitely recommend them for any AC job
Very happy with the job done. I had an additional AC unit installed by Ali and Mohammed, super smooth and excellent service. The manager was very fast in answering all my questions and giving advice on the best solutions. Compared to the previous company I used for the initial installation, it’s day and night different. I would definitely recommend them for any AC job.

3. All Star Air Conditioning
Address: 26 Grosvenor Way
Contact: 020 3519 1340; [email protected]
Hours: Contact to schedule service
When my aircon starts sounding like a bus pulling away, I want a proper diagnosis before agreeing to any work.
Good thing All Star Air Conditioning handles servicing and repairs for London homes and businesses, alongside installations when an old unit has had its last summer.
I like that they offer video surveys and quotations, which can make that first conversation easier to arrange.
Their engineers work across cooling, heating and ventilation, so they’re worth considering when a property has more than one system to look after.
They’re a Daikin D1+ partner and say they can offer equipment warranties of up to seven years on eligible installations.
That’s handy if a service visit leads to a replacement, though I’d check the terms for the specific unit before counting on it.
There’s a catch for larger commercial projects, though: All Star says these need a full building survey. If you’re planning a sizeable upgrade, a video call alone won’t settle the quote.
Customer Reviews
Would absolutely recommend!
Following the heatwaves, we had All Star install a multi-split system in our house, and they’ve been fantastic. Really responsive client team, and a fast and efficient installation on the day. The team talked us through all the steps, kept us in the loop, and made sure the final system was working well. Would absolutely recommend!

Thank you for a fantastic job
Absolutely outstanding service from start to finish. The team carried out a superb installation during the recent heat wave and exceeded all of my expectations. They were punctual, professional, and worked incredibly cleanly throughout the job, leaving everything spotless when they finished. The quality of the installation is excellent, and the air conditioning is working perfectly. I wouldn’t hesitate to recommend them to anyone looking for a reliable and high-quality air-conditioning company. Thank you for a fantastic job.

4. The Air Conditioning Company
Address: Unit 2, Bittacy Business Centre, Bittacy Hill, Mill Hill East
Contact: 020 8346 6000; [email protected]
Hours: Monday-Friday, 8:45 AM-5 PM (phone availability)
When my aircon starts blowing warm air, I want someone who’ll investigate before suggesting a shiny new unit. The Air Conditioning Company services and repairs systems across London, including ones installed by other firms.
Its repair team has fixed 89% of failed units on the first visit in 2024. That’s an encouraging figure, though I’d still expect some faults to need parts and a return trip.
If replacement becomes the sensible option, I’d visit their working showroom to hear the units before choosing one.
They also offer a 10-year warranty on installations and a separate 12-month warranty on repairs, so I’d check which terms apply to my job.
The catch is that I’d need to phone ahead for a showroom visit.
Their phone lines are listed as open Monday to Friday, 8:45 AM to 5 PM, which isn’t ideal when a fault appears at the weekend.
Customer Reviews
Cannot praise him and the company enough
I really recommend The Air Conditioning Company for all your residential Air Con needs. The team in the office were very accommodating when I had to change a last minute booking. Then the engineer who came to service the units throughout my property was excellent. Very friendly, knowledgeable and had a really good work ethic. Cannot praise him and the company enough.

Respected my home
My annual service was done recently. Two AIRCON men worked efficiently and in good humour. One man was an apprentice who worked collaboratively with his colleague. (I was happy that AIRCON is providing apprenticeships). The men were friendly and polite. Respected my home.

5. Aircono – Air Conditioning Expert London
Address: Unit F12E Hastingwood Trading Estate Harbet Road
Contact: 0785 2991 499
Hours: Available 24/7
An aircon breakdown has a knack for happening when I’m finally ready for bed. Aircono says it’s available 24/7 for maintenance and repairs, which is reassuring when the unit picks midnight to call it quits.
The company works on systems in homes and commercial properties and says it has more than a decade of experience. I’d consider them for a routine service as well as a sudden fault, especially if I lived near their North London base.
Their site lists F-Gas, Asbestos Awareness and first-aid credentials, plus free consultations for new installations.
That gives me useful things to ask about when arranging a visit, without assuming every engineer holds every certificate.
The catch is their strong focus on North London areas such as Enfield, Barnet and Islington. If I lived elsewhere in the capital, I’d confirm they could attend before banking on that round-the-clock availability.
Customer Reviews
I would definitely recommend Sebastian and his company to anyone looking for reliable and professional air conditioning services
I recently had my air conditioner installed/serviced, and I’m extremely happy with the experience. Sebastian and his team were professional, punctual, and very knowledgeable. He explained everything clearly and made sure the system was working perfectly before leaving. The air conditioner works great, and the difference in comfort is amazing. I really appreciate the quality of his work and the friendly service. I would definitely recommend Sebastian and his company to anyone looking for reliable and professional air conditioning services.

Thank you to Sebastian and team
Sebastian and his team were professional and really great in installing our air con unit for our commercial property. The interactions before installation, during installation and after have been seemless and, smooth and reassuring. We are grateful for the air con unit, which cools very quickly and has been much needed in this heatwave. Thank you to Sebastian and team.
