About us
More Than Just Air Conditioning
LionAC was founded on a simple idea: heating and cooling should be efficient, affordable and installed by people who genuinely care about the result.
Our story
LionAC is a UK heating and cooling specialist working with homeowners, landlords and businesses across the country. We install and look after air conditioning and air source heat pump systems, from a single bedroom unit to multi-site commercial maintenance contracts.
We started the business because we kept seeing the same things: systems sized by guesswork, rushed installations, and customers left without support once the invoice was paid. We do it differently. Every job begins with a proper survey, every quote is fixed and every customer has a direct line to the engineer who did the work.
As the UK moves away from gas boilers, we're proud to be helping our customers make the switch to cleaner, cheaper heating without sacrificing comfort.
