More than just cooling — modern air conditioning heats, purifies and saves energy all year round.
Heating & Cooling
Every system we install works as a heat pump — cooling your space in summer and heating it efficiently in winter. One system, year-round comfort, replacing portable heaters and fans.
Low Running Costs
Modern inverter systems are A++ energy rated and cost as little as 7p per hour to run. Far cheaper than electric heaters in winter and more effective than fans in summer.
Better Sleep
The ideal sleeping temperature is 16–18°C. Air conditioning maintains it automatically, with dedicated sleep modes and whisper-quiet operation from just 19dB.
Adds Property Value
Air conditioning is increasingly expected in UK homes. A professionally installed system adds real value to your property and is a selling point for buyers and tenants.
Cleaner Air
Built-in filters remove dust, pollen and allergens from your air. Some units reduce bacteria by up to 99% — especially beneficial for allergy sufferers and sensitive environments.
Smart Control
Control your air conditioning from your phone, wherever you are. Set schedules, adjust temperature and monitor energy use with Wi-Fi enabled units from all major brands.
Your comfort is just a click away.

Excellent service from Rob and his team. We run a professional recording studio which relies on efficient air con around the clock. We've had issues with our original installation (from another company) which have been fixed promptly by Rob and his team. Fair pricing and great service!

Answers to the most common questions about air conditioning systems, installation and running costs.
Modern air conditioning is surprisingly affordable to run. A typical 3.5kW wall unit costs around 10–15p per hour in cooling mode. In heating mode, air conditioning is 3–4 times more efficient than electric heaters because it moves heat rather than generating it. Annual running costs for a bedroom unit used regularly are typically £50–£150.
Most single-room air conditioning installations are completed in one day. The process includes mounting the indoor unit, positioning the outdoor unit, running refrigerant pipework, connecting electrics and commissioning the system. Multi-room and commercial installations typically take 2–3 days.
In most cases, residential air conditioning doesn't need planning permission under permitted development rules. However, listed buildings, conservation areas and some leasehold properties may have restrictions. For commercial properties, planning may be needed for external units. We advise on requirements during your survey.
We recommend servicing your air conditioning system at least once a year. Regular maintenance keeps efficiency high, prevents breakdowns, maintains healthy air quality and extends the life of the equipment. Commercial systems and those used heavily may benefit from twice-yearly servicing. F-Gas regulations also require regular leak checks on systems containing refrigerant.
Modern air conditioning systems are very quiet. Premium wall units operate at 19–22dB on their lowest setting — quieter than a whisper and virtually inaudible. Even on higher settings, most indoor units stay below 40dB. We specialise in silent air conditioning installations for bedrooms, studios and noise-sensitive environments.
Yes, almost any room can have air conditioning installed. The indoor unit goes on an internal wall, and refrigerant pipework is routed through the wall to the outdoor unit. Even rooms without an external wall can be served — we route pipework through lofts, voids or along discrete external trunking. We'll show you the best options during a free survey.
