Why It's Worth It
Modern air-to-air heat pumps don't just cool — they reverse to add efficient, gentle warmth through the colder months. That's up to 4 units of warmth for every 1 unit of electricity, a smart supplementary heat source alongside your existing heating.
Quiet, filtered cooling when temperatures rise — perfect for bedrooms and south-facing living rooms.
The same unit reverses to add efficient, gentle warmth — a useful boost alongside your existing boiler and radiators.
Up to 3× more efficient than gas or electric heating.
A fraction of the carbon emissions of fossil-fuel systems.
Aligned with the UK's move away from gas boilers.

"Barnet Air installed a discreet wall unit in our bedroom and you genuinely can't hear it. The engineers were tidy, polite and finished in a day. Best home upgrade we've done."
Peter T.
Finchley, N3
"We had a multi-split system fitted across three bedrooms. Pricing was exactly what they quoted — no surprises — and the pipework is almost invisible. Highly recommend for anyone in Hertfordshire."
David & Rachel K.
St Albans
"Booked the annual service and clean after our unit started smelling musty. Turned up on time, explained everything, and it's blowing like new again. £99 well spent."
James P.
Edgware, HA8
"From the first survey to the final certification, the whole process felt premium. They even matched the trunking to our wall colour. Couldn't be happier with the finish."
Priya N.
Hatfield
"Our old system kept tripping the breaker. Another firm wanted to replace the lot — Barnet Air diagnosed a faulty capacitor, fixed it in an hour and charged fairly. Honest engineers."
Tom H.
Borehamwood, WD6
"We added an air purification unit for my husband's asthma. The difference in the house within a week was remarkable. Thoughtful advice and a really clean install."

The UK recorded some of its hottest summer temperatures on record this year, and climate scientists warn that future summers are likely to be even hotter and longer. For homes in North London and Hertfordshire — many built to hold heat in, not keep it out — a quiet, efficient air conditioning system is fast becoming a year-round comfort essential rather than a luxury.
A quick three-step survey — we'll follow up within one working day with tailored advice.
