"Faultless from quote to install. The engineer was spotless, friendly and had our bedroom unit running by lunchtime. So quiet I forget it's on."

Frequently asked questions
Can I just buy a unit, or do you install too?
Both. Buy any unit for self-install or a DIY-ready package, or let us arrange a fully fitted, F-Gas certified installation by a vetted local engineer. You choose at checkout.
How much does air conditioning cost to run?
Our A+++ inverter units sip power - a typical 3.5kW model costs roughly 12–20p per hour to run on cooling, far less than older fixed-speed systems. Heat-pump mode also makes them cheaper to heat with than many electric heaters.
Do you cover my area?
Yes - we cover the whole of the UK with local engineers in every region. From Aberdeen to York, there's a fitter near you.
How long does installation take?
A single wall-split is usually fitted in a day. Multi-room and whole-home systems take one to three days depending on pipe runs and access.
Is there a guarantee?
Every installation includes up to a 5-year workmanship guarantee, and units carry up to a 7-year manufacturer warranty when serviced annually.
