Air Conditioning

How Does Air Conditioning Work?
Every system has two parts — an indoor unit and an outdoor unit — interconnected by refrigerant pipes and a power supply, neatly run through trunking for a clean, discreet finish.
Two parts — an indoor unit and outdoor unit — connected by pipes and trunking.
The Indoor Unit
Mounted on your wall, ceiling or hidden in the loft, the indoor unit quietly distributes conditioned air into your room. It contains the evaporator coil and fan — blowing cool air in summer or warm air in winter.

Modern air conditioning does more than cool — it saves energy, runs silently, and blends in with the building.
Energy Efficient
Today's inverter-driven systems use up to 60% less energy than older models. Variable-speed compressors adjust output to match demand, so you only pay for the cooling or heating you actually need. Many units achieve an A+++ energy rating — keeping bills low and carbon footprint smaller.

Year Round Comfort
Every system we install provides both cooling and heating. In summer your rooms stay cool and dehumidified; in winter the same unit delivers efficient warmth at a fraction of the cost of conventional heating. One system, every season.

Cleaner Air
Modern air conditioning filters remove dust, allergens and pollutants from the air you breathe. Built-in filtration systems capture particles as small as PM2.5, helping reduce hay fever symptoms, asthma triggers and airborne bacteria — creating a healthier indoor environment all year round.

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.
A single-room wall mounted air conditioning system typically costs from £1,800 fully installed, depending on the unit size and complexity of the installation. Multi-room systems cost more but are cheaper per room. We provide fixed-price quotes after a free survey — no hidden 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.
