"Had a wall-mounted unit installed in our bedroom before the heatwave. Tidy install in a day, whisper quiet and the app control is brilliant. First good night's sleep in weeks."
"Multi-split system fitted to our home office and lounge. Clear fixed quote, no mess, and it heats the rooms in winter for a fraction of what the radiators cost."
"Our conservatory was unusable in summer. They fitted a unit that keeps it perfect all year round — and serviced my mum's system in Swindon while they were at it. Proper local firm."

Send Us a MessageA single wall-mounted split air conditioning unit professionally installed typically starts from around £1,600–£2,000, with multi-split systems covering two or more rooms quoted individually. After a free home survey we give you a clear, fixed quote with no hidden extras. See our full cost guide.
Most single-room installations are completed in one working day. Multi-split systems covering several rooms usually take one to two days. We protect your home, tidy as we go and fully commission the system before we leave.
Yes — every system we install is an air-to-air heat pump, which cools in summer and provides very efficient, low-cost heating in winter. For every 1kW of electricity used you get 3–4kW of heat, making it far cheaper to run than plug-in electric heaters. Read more in our heat pump guide.
Yes. It's a legal requirement for anyone installing or servicing air conditioning containing refrigerant to be F-Gas certified. Our company is REFCOM registered and every engineer holds the City & Guilds 2079 F-Gas qualification, so your installation is fully compliant and your warranty is protected. See our F-Gas regulations guide.
Much quieter than people expect. The indoor units we fit run as low as 19–26 decibels — quieter than a whisper — and the outdoor condenser is positioned carefully to keep noise away from bedrooms and neighbours.
We recommend an annual service for domestic systems and twice-yearly maintenance for commercial air conditioning. Regular servicing keeps the system efficient, protects your manufacturer warranty and catches small faults before they become expensive repairs.
Yes, considerably. A properly installed split system is quieter, far more efficient, doesn't need a hose hanging out of a window, heats as well as cools, and adds value to your home. Portable units cost more to run per degree of cooling and struggle in a real heatwave. See portable vs fixed air conditioning.
