HERTFORDSHIRE, BEDFORDSHIRE & CAMBRIDGESHIRE
Wall mounted and multi-split air conditioning in Cambridge, installed by F-Gas certified engineers. Cools in summer, heats in winter, and 0% VAT applies on most residential installations.

Air conditioning in Cambridge has shifted from rare luxury to genuine necessity over the last few summers, and the city’s housing makes the problem more acute than most. Solid Victorian and Edwardian brick walls along Mill Road, Romsey and Petersfield hold the day’s heat right through the night. South-facing front bedrooms in the Newnham villas backing onto the Backs catch full afternoon sun. The Anglia Ruskin University buildings and University-related commercial premises across the city centre have heat loads from equipment and staff that the original buildings never anticipated. Loft conversions are absolutely everywhere across the Mill Road area, and a loft conversion in a Victorian terrace under steep tiled roofs becomes a sauna in July. Then there’s the Cambridge Science Park and Biomedical Campus commercial market where AC is genuinely critical infrastructure rather than a nice-to-have.
Wall-mounted, multi-split and ducted air conditioning for homes, offices and commercial premises through our air conditioning installation service. F-Gas qualified engineers.
Two things have changed. UK summers genuinely get hotter; 30°C-plus heatwaves now happen most years rather than once a decade, and Cambridge’s predominantly Victorian and Edwardian housing was built for a British climate that no longer reliably exists. Solid brick walls, original sash windows and pitched tile roofs hold heat brilliantly in winter and trap it disastrously in summer. A modern AC split system cools effectively, runs almost silently, and in winter doubles as a heat pump three to four times more efficient than electric panels.

Our most-installed brand in Cambridge homes. Quiet, energy-efficient (A+++ on most models), and the slim wall-mounted indoor units sit unobtrusively in period rooms with original cornices and picture rails. Five-year warranty as standard, ten on selected ranges when fitted by an accredited installer.
Our preferred choice for ducted systems in substantial Newnham villas and the larger Cambridge commercial premises. The City Multi range works well for multi-room cooling from a single outdoor unit, and the slim ceiling cassette units suit Anglia Ruskin University buildings and similar premises where wall-mounting would compromise the aesthetics.
Solid mid-range options. Samsung’s Wind-Free range is particularly suited to bedrooms in the Mill Road and Romsey terraces, no direct air draught, useful in compact bedrooms where you’d otherwise feel the breeze at night.
Air conditioning systems need annual AC maintenance to perform properly and stay under warranty. F-Gas regulations require certified checks on systems with over 3kg of refrigerant, but even smaller domestic units benefit from yearly filter cleaning, coil inspection and condensate drain checks. Our air conditioning servicing catches problems in spring before the hot months bite. Skipping AC maintenance typically shows up as poor cooling performance during the first hot week of summer, exactly when every installer in East Anglia is booked solid.
Survey, supply, installation and commissioning by our own engineers, with the trunking run properly.
Cambridge City Council pays attention to visible outdoor units on prominent elevations within the conservation area. We design discreet placements as standard, rear elevations, hidden side walls, pipework routed internally through loft voids.
Generous plots, more outdoor unit placement flexibility. Often justifies multi-split or small ducted systems serving multiple rooms, particularly south-facing bedrooms catching afternoon sun off the river.
Common as families add space without moving from period stock. Heat sits at the top of any house, particularly under steep tiled roofs. A single wall-mounted unit on the gable wall usually sorts the whole loft.
Offices, retail units and University-related premises across the city centre and along Mill Road. Sized for actual heat loads including staff, equipment and customer footfall, not just floor area.
Where AC is genuinely critical infrastructure, server rooms, lab spaces, biotech premises. Redundant systems with N+1 capacity, predictable maintenance contracts, and rapid emergency response when something fails.
A single-room residential wall-mounted split system in Cambridge runs £2,500 to £3,500 fitted. Multi-split installs covering two or three rooms typically sit £4,800 to £8,500. Ducted systems for substantial Newnham villas £8,000 to £15,000+. Commercial AC pricing varies by specification. Annual AC maintenance £150 to £250 per outdoor unit.

Domestic AC is generally permitted development providing the outdoor unit isn’t on a wall facing a highway and is set back from boundaries. Listed buildings and properties within the Mill Road and St Matthew’s Conservation Area need additional consideration. We check during the survey.
Annually. F-Gas regulations require certified checks on systems with over 3kg of refrigerant, but even smaller units benefit from yearly cleaning and inspection. Best done in spring before the hot months start.
Yes, commercial AC for science, lab and biotech premises is a meaningful part of what we do. Specification varies enormously by use case (server rooms vs general office vs lab spaces), and we design accordingly with appropriate redundancy.
Usually one of three things: under-sized for the room (a common mistake by installers quoting off floor area alone), refrigerant low after years without servicing, or condenser coils blocked with dust and pollen. Annual AC maintenance prevents the last two.
Yes, modern heat-pump split systems both cool in summer and heat efficiently in winter. They produce 3 to 4 kW of heat for every 1 kW of electricity used, making them significantly cheaper than electric heaters.
