How We Reviewed
- Fast Response Times: Fast response times matter, so we picked companies that get to you quickly during emergencies. No one wants to sweat it out for days waiting for a fix when the heat is on.
- Strong Service Guarantees: Strong service guarantees stood out to us. When a company offers good labour and parts warranties, it shows they really believe in their work and want to protect your investment for the long haul.
- Deep Industry Experience: Deep industry experience counts, too. Teams with years of hands-on work usually make repairs go a lot smoother, and we made sure to highlight those with great track records across London.
- Clear Pricing Transparency: Clear pricing transparency is a must, because free estimates help you stay in control of your budget. We looked for providers who are totally upfront about costs, so you always know what to expect.
1. London Air Con

Website: londonaircon.net
Address: S201 Garden Studios, 71-75 Shelton St.
Contact: +44 (0) 800 208 6722 | [email protected]
Hours: Monday-Thursday, Saturday-Sunday, 7:00 AM – 7:00 PM | Friday, 9:00 AM – 7:00 PM
London Air Con has over 30 years of hands-on experience with every job and offers a solid 12-month labour warranty, which really puts people at ease. They even have public liability insurance up to £10 million.
As for their aircon servicing, they can repair third-party aircon systems from top brands. So, even if they didn’t install it, you can count on them to help keep your climate control running smoothly.
Safety is a big deal for them, too, given their full CHAS certification. Their engineers always stick to industry rules and handle everything, including refrigerants, with care and legally.
However, getting an estimate can be a hassle since you have to send in your exact room sizes by phone or email, which feels a bit old-school. Parts warranties can also vary depending on the brand, so take note of this.
We cannot recommend their service enough
We were introduced to John of London Aircon and his team by one of their customers. We were impressed with how professional and friendly the team were and they installed Air Conditioning units into our offices.
We cannot recommended their service enough and any issues encountered were quickly overcome. Thanks to John and his team and keep up the good work it was a belter!

I found their pricing competitive
London Air Con undertook some aircon unit relocation works for us on behalf of our client during a light refurbishment project. I found their pricing competitive and their service of a highly professional standard. I will definitely be using John and his team again

2. The Air Conditioning Company

Website: airconco.com
Address: Unit 2, Bittacy Business Centre, Bittacy Hill
Contact: 020 8346 6000 | [email protected]
Hours: Monday-Friday, 8:45 AM – 5:30 PM
The Air Conditioning Company stands out with their 10-year warranty on every installation, giving you tons of peace of mind. Their engineers are super quick too, aiming to respond to emergency breakdowns within just four hours.
Plus, they’ve got the biggest selection of portable aircon units for hire in the UK, so you don’t have to worry when a sudden heatwave hits.
When our office system broke during a bad heatwave last summer, we tried their same-day delivery for a portable unit. It was a total lifesaver and had us back to work in no time.
Another perk is that you can check out their city showroom and see different units in action before buying.
On the downside, you can only reach phone support on weekdays during office hours. You’ll need to book an appointment just to visit their showroom.
The men were friendly and polite
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.

A very professional job inside and out
From start to finish the Aircon company were great to deal with. The initial survey was conducted promptly after my inquiry and a quote quickly received. On the installation date, the engineer arrived promptly and worked very efficiently, he was exceptionally clean and tidy and even re-hung a heavy mirror for me which had to be moved to accommodate the Aircon unit. A very professional job inside and out with high-quality materials. Would highly recommend.

3. All Star Air Conditioning

Website: allstar-aircon.co.uk
Address: 26 Grosvenor Way
Contact: 020 3519 1340 | [email protected]
Hours: Monday-Friday, 8:00 AM – 5:00 PM
All Star Air Conditioning really takes equipment quality seriously since they’re an official Daikin D1 partner. This top-level certification means you get the best gear, plus extended warranties that last up to seven years for extra peace of mind.
Another highlight is their maintenance plans, which are flexible. They tailor everything to your exact needs instead of using a boring checklist.
The team is also great at working in historic or listed city buildings, handling upgrades with care so there’s hardly any disruption while you work or shop. This focus on being quiet and efficient makes them a solid pick for busy stores that can’t afford interruptions.
The only downside is that they mainly work with Daikin systems, so you won’t have many choices if you want another brand.
Really efficient, polite, friendly, fair value
Recommended by a friend, and we were so happy with the service. Really efficient, polite, friendly, fair value, quick & thorough installation + clean up… and the air con works like a dream!!

4. Calibre Climate

Website: calibreclimate.com
Address: 126 Hempstead Road, Kings Langley
Contact: 020 3191 9131 | [email protected]
Hours: Monday-Friday, 7:30 AM – 4:30 PM
Calibre Climate makes it simple to upgrade your home’s climate system with their all-in-one retrofit service, so you don’t have to juggle different contractors.
All their engineers are fully qualified and F-Gas certified, so you know your home’s in safe hands. And with nearly 50 years in luxury climate control, you can trust they’re true experts.
Their Inversa system is pretty impressive since it can manage your heating, cooling, and hot water with just one outdoor unit.
Their aftercare team also stands out for their white-glove approach, making sure your space and privacy are respected at all times. They also give a detailed survey report within 24 hours of an assessment.
The main downside is the steep £280 call-out fee for urgent problems. Also, you’ll need to book ahead before visiting their showroom.
5. JP Air Conditioning

Website: jpaircon.com
Address: 53 Homesdale Road
Contact: 02083331191 | [email protected]
Hours: Monday-Friday, 9:00 AM – 5:00 PM
JP Air Conditioning really puts your mind at ease with their 24/7 phone support, so there’s always someone to help any time you run into trouble.
In fact, one customer shared that they called the emergency line late one winter night and got immediate help. She added that they even guided her through troubleshooting.
Their same-day call-out service is another highlight. This means you don’t have to wait long when your system breaks down, and they also give completely free, no-obligation estimates.
Plus, every job comes with a 12-month guarantee that covers both parts and labour, so you know you’re protected.
On the flip side, their seven-year warranty on parts only sticks if you always use their team for routine servicing. Additionally, their office is closed on weekends.
Did an excellent job and explained everything
I booked a service from JP Air Con. The first guy that came wasn’t great and did only a cursory job so I complained to the office and they sent a second guy who did an excellent job and explained everything. I was very happy with how they dealt with my complaint and would use them again.
