“Con Air are great this is the 2nd time I have used them, this time to fit air conditioning in our bedroom. The guys are very polite and take time to explain the options and choices, and very quick to get back to any questions I had. Very competitive quote, very neat and tidy and a pleasure to have them in my home — can’t recommend enough.”

The whole installation process was so smooth and stress-free from start to finish, and the communication throughout was fantastic. A huge thank you to Connor and the whole team — we’re absolutely delighted with the end result! We wouldn’t hesitate to use Conair again and would 100% recommend them to anyone. 5-star service all round. Thank you so much!”
Common questions
How much does air conditioning installation cost in Portsmouth?
It depends on the size of the room, the system you choose and how the pipework needs to be routed. We give a free, no-obligation quotation with a fixed price before any work starts — send us your details and we'll usually come back the same working day.
Do you install air conditioning in flats and terraced houses?
Yes. Much of our Portsmouth work is in terraced and period properties where the outdoor unit and pipework need careful positioning. We route pipework neatly and leave everything clean and tidy. If you rent or are in a leasehold flat, you'll need the freeholder's permission before we install.
Can you repair a system another company installed?
Yes — we diagnose and repair all major makes and models, including Samsung, Mitsubishi Electric, Daikin and Hitachi, whoever fitted them.
Do you service air conditioning as well as install it?
Yes. Regular servicing keeps a system efficient, hygienic and within its manufacturer warranty. We look after one-off home units and planned maintenance for commercial sites.
