Most of our work is residential: single rooms, whole-house multi-split systems, and everything in between. This page covers general domestic air conditioning — if you're specifically after a bedroom, home office, garden room or conservatory, our dedicated pages below go into more detail for that particular space.
Who domestic air conditioning suits
Domestic air conditioning suits homeowners who want reliable, efficient heating and cooling in one system rather than juggling portable units in summer and radiators in winter. It's equally at home in a single-room retrofit for a hard-to-heat extension as it is across a whole house on a multi-split system feeding several rooms from one or two outdoor units. Renters generally need landlord permission before installation, since it involves fixing equipment to the building.
Heating and cooling benefits
Every system we install is a reversible heat pump: the same indoor and outdoor unit pair cools a room in summer and heats it in winter, so it isn't a single-season purchase. Because heat pumps move heat rather than generate it directly, they're typically cheaper to run for heating than an equivalent electric heater, and they bring a room up to temperature in minutes rather than the slow build of a radiator circuit warming up.
Sizing considerations for a whole home
Sizing is done room by room, not house by house — a single split system is sized to one room's floor area, glazing, insulation and orientation, while a multi-split system pairs several correctly sized indoor units to a shared outdoor unit. Undersizing leaves a room struggling on hot days; oversizing causes short-cycling, which is noisier and less efficient. Our online quote calculator asks for each room's dimensions so the guide price reflects a properly sized system rather than a generic estimate.
Noise and indoor unit positioning
Modern wall-mounted indoor units run quietly at normal settings, and most have a dedicated quiet or night mode that reduces fan speed further. Positioning matters as much as the unit's spec sheet: we avoid mounting directly above a bed headboard or a desk chair where possible, and we route airflow away from where people sit or sleep for most of the day.
Outdoor unit and pipe-routing considerations
The outdoor unit needs a stable, ventilated position with enough clearance for airflow — typically a wall bracket, ground pad, or flat roof area. For multi-room installations we plan pipe runs before quoting, since longer runs or awkward routes (through multiple floors, or externally around a building) affect both the price and how the pipework is concealed. Trunking to hide visible pipe runs is priced separately so you can see exactly what you're paying for.
0% VAT on qualifying installations. Since 2022, HMRC has applied a temporary 0% VAT rate to the supply and installation of qualifying energy-saving materials in residential properties, including reversible air-to-air heat pump systems — and most air conditioning units qualify, since they heat as well as cool. The relief runs until 31 March 2027. Eligibility depends on the property and installation; this isn't tax advice, and we'll confirm the correct VAT treatment on your written quote. See our full 0% VAT guide for the detail.

Common questions
- Can one system cool and heat my whole house?
- A multi-split system can serve several rooms from one or two outdoor units, but each room still needs its own correctly sized indoor unit. We size every room individually rather than treating the house as one figure.
- Do I need a survey before I get a price?
- No — the online quote calculator gives a real, itemised guide price based on your room sizes. A free site survey then confirms the final figure before anything is booked.
- How long does a domestic installation take?
- A single-room install is typically done in a day. Multi-room or whole-home installations take longer, and we'll give you a time estimate as part of your survey.
- Does domestic air conditioning qualify for 0% VAT?
- Many qualifying residential installations currently benefit from the government's temporary 0% VAT relief. Eligibility depends on the property and installation — see our 0% VAT guide for the detail.
- Why do you only install Haier?
- Haier is a genuinely reliable, well-specified brand with a 6-year warranty as standard. Sticking to one brand keeps our stock, training and spares consistent, which helps keep installation and servicing costs down.
- Do you also service systems you didn't install?
- Yes — we service Haier and most other major brands, whether or not we carried out the original installation.
