5 Best Air Conditioning Companies in Belfast for Year-Round Comfort
Air conditioning in Belfast isn’t exactly the first thing most of us grow up thinking about. Then one warm spell, stuffy office, or overheated bedroom comes along, and suddenly it feels rather essential.
I looked at the best air conditioning companies in Belfast for reliable installation, servicing, and ongoing support. These are the Belfast companies I’d shortlist for practical advice and dependable climate control.
And if you’re weighing up broader heating and cooling work too, our guide to HVAC contractors in Belfast is a useful place to compare your options!
How much does air conditioning cost in Belfast?
For a typical single-room split system, expect to pay around £1,400 to £2,500 supplied and fitted. The final bill depends on the unit, room size, property layout, and any electrical work involved.
Cooling two or three rooms with a multi-split setup usually costs £3,200 to £6,500. A full ducted system is a much bigger investment at roughly £6,000 to £15,000+.
Portable air conditioners are the budget-friendly option at around £250 to £700. They’re useful for occasional cooling, but they don’t offer the same permanent setup as an installed system.
If your electrics need upgrading, allow another £400 to £700. Engineer labour can range from about £280 to £720 per day, depending on the complexity of the job.
1. SP Climate Control
Address: Newtownabbey, BT36 4bb, Northern Ireland
Contact: 07383 820420 | shane@spclimatecontrol
Hours: Monday-Friday, 8 AM – 5 PM
SP Climate Control is the sort of company I’d ring when I want proper air con advice without feeling like I’ve wandered into an engineering lecture.
Shane keeps the service personal, which is a nice change from being passed around like a parcel.
They work with air conditioning and heat pumps across Northern Ireland, covering both homes and commercial spaces.
Their maintenance plans include priority scheduling, service reports, and reminders, so your system gets attention before it starts making expensive-sounding noises.
I also like that the whole setup feels specialist but still approachable. It’s especially handy if you want ongoing support rather than an install-and-disappear act.
The only extra step is the site inspection before a firm quote is confirmed. Still, that’s probably better than getting a suspiciously neat price before anyone’s even seen the place!

Honest AC Diagnosis and Prompt 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 con without turning the whole job into a science project.
They handle both domestic and commercial systems across Northern Ireland, so the service range is pleasantly broad.
You can choose from single-split, multi-split, and ducted setups, depending on how much space needs cooling. I especially like the multi-split option, because several rooms can be covered without the outside wall looking like it’s sprouted machinery.
Their maintenance plans are flexible, with options based on how many units you have and how you want to pay. Genuine manufacturer-sourced parts are another reassuring touch when something needs repairing.
The only thing I’d check is weekend support, since the published contact hours are weekdays only.
If out-of-hours help matters, it’s worth asking before the air con picks Saturday night to misbehave.

Clean and Professional Home 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: [email protected] | 028 9045 1010
Hours: Monday-Thursday, 8:30 AM – 5 PM | Friday, 8:30 AM – 4 PM (24/7 helpdesk)
solv Group really shines when it comes to larger jobs. They can smoothly and efficiently install air conditioners in offices, hotels, and other commercial buildings.
With over 20 years in business, their experience runs deep. They have solid experience in commercial heating, ventilation, and air conditioning across Northern Ireland.
I also really appreciate their focus on planned preventative maintenance. I think that’s a far smarter strategy than dealing with breakdowns after the fact.
Plus, existing commercial clients get access to 24/7 emergency support. This is incredibly handy when the AC decides office hours are merely a suggestion.
Just note that their services lean heavily commercial. Homeowners looking for a simple single-room setup should definitely check first to ensure the job fits within their domestic scope.
4. Aircon
Address: Unit 22, Harbour Court, 5 Heron Road
Contact: 028 9046 6222 | [email protected] | [email protected]
Hours: By appointment
What I liked most about Aircon is that they seem to do it all themselves, from design and installation to servicing and maintenance.
On top of that, they handle everything from basic split systems to VRF, VRV, and close-control setups without needing to bring anyone else in.
Having their own TM44-accredited assessor is a smart touch too, especially for larger commercial systems that need proper sign-off.
The engineering side feels solid as well. The CAD design and heating and cooling calculations are done in-house, so you’re not relying on someone else’s numbers.
Given that Aircon has been in the industry since 1996, none of this really surprised me. That kind of experience tends to show, especially in how they approach maintenance, which felt like one of their strongest areas.
If you’re not on a contract, though, it’s worth asking about call-out pricing early. Contract customers often get better reactive rates.

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
What struck me about Chill Gas is that Carl Hill and his wife only set the business up in 2020. Yet between them, they’re bringing over a decade of trade experience, so it doesn’t feel like a startup finding its feet.
Based in Belfast, their F-Gas-registered engineers cover both homes and commercial spaces across Northern Ireland. This is reassuring when you’re inviting someone in to work on your heating and cooling.
I also liked that they don’t just do air conditioning. Cooling, heating, and heat pumps are all part of their remit, which suits properties that need more than a single unit bolted to the wall.
That broader range makes them worth considering for renovations or bigger upgrades too, without the job turning into an overengineered production.
On the downside, weekends are off-limits for routine work. They only respond outside weekday hours for genuine emergencies, so anything non-urgent will need to be booked within the standard working week.
