The 5 Best Air Conditioning Companies in Belfast for a Cooler Home
Belfast doesn’t really do heatwaves, until suddenly it does, and every office and living room in the city turns into a greenhouse overnight because nobody planned for
I’ve used general HVAC contractors before for basic heating jobs, but proper air conditioning is a different skill set. And those rare hot spells are exactly when you find out who actually has it.
So I went looking for air conditioning companies in Belfast with the engineering know-how to back up the sales pitch. These are the teams I’d trust with anything from a stuffy bedroom to a server room that can’t afford to overheat.
If your AC needs more than a jack-of-all-trades, this list is worth a look. Here’s who made the cut.
How much does air conditioning cost in Belfast?
A standard single-room split system in Belfast usually costs £1,400 to £2,500 supplied and fitted. The price depends on the unit size, property layout, and electrical requirements.
A multi-split system for two to three rooms costs around £3,200 to £6,500. A ducted whole-home system is pricier at roughly £6,000 to £15,000 or more.
Portable air conditioners typically cost £250 to £700. They’re the cheaper option if you don’t need a permanently installed system.
If your property needs an electrical wiring upgrade, budget another £400 to £700. Engineer labour can range from about £280 to £720 per day.
For most straightforward installations, it’s worth getting a few itemised quotes. That makes it easier to see what’s included in the equipment, installation, electrical work, and labour.
1. SP Climate Control
Address: Newtownabbey, BT36 4bb, Northern Ireland
Contact: 07383 820420 | [email protected]
Hours: Monday-Friday, 8 AM – 5 PM
SP Climate Control has the kind of personal feel that can make organising air conditioning work a lot less daunting.
Instead of dealing with random contractors, Shane serves as a familiar, consistent point of contact for both residential and commercial spaces. This ensures you always know exactly who is handling your job.
I particularly appreciate that ongoing maintenance isn’t treated as an afterthought. Their service plans include priority scheduling, detailed reports, and timely reminders.
This makes this team a practical choice if you prefer staying ahead of issues rather than chasing them later.
The only minor catch is that they require a site inspection before confirming a firm quote. I personally don’t mind because it gives the team a chance to price the work around your actual space and requirements.

Honest Same-Day AC Repair
Shane was amazing! I called and said I was told I need a new AC unit. Shane came out that day on a Friday night! He was honest and said I just needed some cleaning, which he did there and then! He was honest about the time frame and that I didn’t need a new unit immediately! I highly recommend!!! I will be using for maintenance and any AC needs in the future!

2. Belfast Cooling
Address: 8 Foxton Green, Newtownabbey
Contact: 07726 346024 | [email protected]
Hours: Monday-Friday, 9 AM – 6 PM
Belfast Cooling is the sort of company I’d shortlist when I want proper air conditioning help without needing a crash course in HVAC jargon.
They handle both domestic and commercial systems across Northern Ireland, which makes them useful for everything from bedrooms to busy workplaces.
I also like the flexibility in the setup options, especially the choice between single-split, multi-split, and ducted systems. Their multi-split units can serve several rooms without making the outside wall look like it’s collecting machinery.
Maintenance is another strong point, with plans tailored to the number of units and your preferred payment schedule. Using genuine manufacturer-sourced parts for repairs gives me a bit more confidence too.
The only thing you should double-check is weekend support. Since their listed contact hours are strictly weekdays, it’s definitely worth asking about out-of-hours help before an emergency actually strikes.

Excellent Two-Unit AC Installation
Highly recommend Aaron at Belfast Cooling. We got two air conditioning units put in, and the service was excellent! Great communication, tidy, good price too. He did an excellent job from start to finish and was very reliable. I would highly recommend!

Professional and Tidy Bedroom AC Installation
My partner and I got AC installed in our bedroom; couldn’t fault Aaron and the guys, highly professional and very tidy, would highly recommend so much so we’re getting them back in a few months for more AC for downstairs. Couldn’t fault this company, worth more than 5 stars.

3. solv Group Boiler Service & Repairs
Address: Unit 12 Tamar Commercial Centre, 25 Tamar Street
Contact: 028 9045 1010 | [email protected]
Hours: Monday-Thursday, 8:30 AM – 5 PM | Friday, 8:30 AM – 4 PM | 24/7 helpdesk
solv Group is the kind of company I’d call when the job involves more than one temperamental unit in the corner of a room.
With over 20 years in business, they’ve built solid experience in commercial heating, ventilation, and air conditioning across Northern Ireland.
Their natural territory is bigger sites, including offices, hotels, and other commercial buildings. Planned preventative maintenance is a big plus too, because waiting for something expensive to make a strange noise is rarely a brilliant strategy.
Existing commercial customers can access a 24/7 helpdesk and emergency support. That’s handy when the air con decides business hours are merely a suggestion.
The main caveat is that their air conditioning services lean commercial.
Homeowners after a simple single-room setup may want to check first that the job suits their domestic scope.
4. Aircon
Address: Unit 22, Harbour Court, 5 Heron Road
Contact: 028 9046 6222 | [email protected] | [email protected]
Hours: By appointment
Aircon has been around since 1996, which is reassuring when you’re dealing with systems more complicated than a wall unit and a remote.
They provide complete design, installation, servicing, and maintenance. This includes working with everything from standard split systems to advanced VRF, VRV, and close-control setups.
I like that they keep CAD design and detailed heating and cooling calculations in-house. It gives the whole process a more engineered feel, which matters when commercial spaces start getting large, awkward, or both.
They’ve got an in-house TM44-accredited assessor too, so businesses with larger systems can cover compliance without adding another contractor to the mix.
Their maintenance experience is another strong point, especially for offices, retail, leisure, and other busy sites.
The only thing I’d clarify is one-off call-out pricing. Contract customers get preferential reactive rates, so occasional users should ask what ad-hoc support will cost.

5. Chill Gas Ltd
Address: Unit 7a-7b Weavers Court, Weavers Court Business Park
Contact: 028 9278 9258 | [email protected]
Hours: Monday-Friday, 9 AM – 6 PM
Chill Gas has a more personal feel than some larger HVAC firms, which I like when I’m inviting someone into my home to sort out the temperature.
Founded in 2020 by Carl Hill and his wife, the Belfast-based family business brings more than a decade of trade experience to the job.
Their F-Gas registered engineers work on air conditioning for both homes and commercial spaces across Northern Ireland.
I’d particularly consider them if I wanted one company that understands cooling, heating, and heat pumps rather than treating each as a separate universe.
The wider service range is handy for refurbishments or properties that need more than a basic AC install. It gives Chill Gas a useful all-rounder quality without losing that smaller-company feel.
That said, they’re closed on Saturday and Sunday. Only genuine emergencies get 24/7 cover, so routine bookings outside weekdays may be harder to arrange.
