A single-room split system is £1,150 to £1,450 fitted, depending on the pipe run and mounting. You'll get an itemised quote within 24 hours of the survey, and the invoice matches it to the pound.

One day for a single room: 8:00 start, cooling by late afternoon. Multi-room systems take two to three days, and we agree the schedule before we start.

For most houses a wall-mounted system is usually permitted development, but conditions apply. Flats and maisonettes normally need freeholder consent; listed buildings and conservation areas often need consent; and siting and noise limits apply in all cases. We check what your property needs before you commit and handle any paperwork.

Filter deep-clean, refrigerant charge and airflow checked against the manufacturer's figures, condensate flush, and a one-page efficiency report with the actual numbers.

Emergency call-outs seven days a week, usually same day, with a 90-minute arrival window (phone lines Mon–Sat 7:00–19:00). Comfort members get priority slots and pay no call-out fee on covered visits.

Yes. Every unit 21Aircon fits is a heat pump: it cools in July and heats in January, at roughly a third of the running cost of electric radiators.

No: it is one of the cheapest ways to heat and cool a home. A heat pump moves warmth rather than burning energy to make it, so, depending on the system and how you use it, for every £1 of electricity you get roughly £3 to £4 of heating or cooling back. That is often about a third of the running cost of electric heaters, and an annual service keeps it working at its best.
