Air conditioning installation in Portsmouth
Single and multi-split systems fitted by F-Gas certified engineers. We pass your details to installers who cover your postcode.
Portsmouth sits almost entirely on an island, and the sea keeps summer nights milder than inland Hampshire. Loft conversions in terraced houses and top-floor flats are the exceptions: they trap heat and often stay hot well after dark.
About a third of Portsmouth households live in flats, and loft rooms are common in the Southsea terraces, so those are the main places people fit air conditioning.

Where the outdoor unit can go
In a terrace, the back wall or rear yard is the usual spot. Units facing the street in a conservation area are unlikely to be accepted. Check with Portsmouth City Council's planning team, since the rules for air conditioning differ from those for heat pumps.
Keep the unit clear of neighbours' windows. Noise complaints are a common reason units have to be moved.
Choosing the system
A single split cools one room. A multi-split runs two or more indoor units off one outdoor unit, which suits a loft room and a bedroom together. Ask for a heat gain calculation, not a guess based on floor area.
Units near the seafront benefit from corrosion protection on the outdoor coil.
F-Gas and paperwork
Only F-Gas certified engineers can install and commission the refrigerant circuit. You should get a commissioning sheet and warranty details. An air-to-air system bought as your main heating may qualify for the £2,500 Boiler Upgrade Scheme grant.
Portsmouth homes and what they need
Victorian and Edwardian terraces
Loft conversions with dormer windows are the hottest rooms. A wall unit there, with the condenser on the rear roof or wall, is the common setup.
Converted houses and purpose-built flats
Leaseholders need the freeholder's agreement. In tall blocks, the outdoor unit may have to sit on a balcony.
1930s semis on the mainland side
Side walls give room for the condenser away from bedrooms. A reversible system can heat a conservatory in winter too.
Areas covered
Engineers who cover Portsmouth work across areas including Southsea, Fratton, North End, Copnor, Milton, Eastney, Hilsea, Cosham, Drayton and Farlington.
Questions people in Portsmouth ask
Is air conditioning expensive to run?
A modern inverter split is efficient. Running costs depend on how many hours you use it and your electricity tariff.
Do I need to service air conditioning?
Yes, ideally once a year. The engineer cleans the filters and coils, checks the refrigerant and drains, and looks at the outdoor unit for corrosion, which matters near the coast.
