Home air conditioning
F-Gas registered Daikin and Mitsubishi air conditioning installation across the North East from £1,500. Reversible heat-pump split systems — cooling in summer, supplementary heating in winter. Whisper-quiet operation from 19 dB(A).
Modern home air conditioning isn't cooling-only. Every split system we install is a reversible heat pump — the same unit cools rooms in summer and delivers supplementary heating in winter. For shoulder seasons (April-May, September-October) running a Daikin split in heating mode is often more efficient than firing the gas boiler for a single room.
UK summer temperatures have risen meaningfully — three of the five hottest UK summers on record are post-2018. Modern well-insulated homes (the same insulation that helps winter performance) increasingly retain summer heat overnight, making bedrooms unpleasant for sleep. For about 1 in 4 of the homes we survey now, air conditioning is the right answer for at least one or two rooms.

Common applications
The single biggest growth area since 2020. Home offices — particularly converted garages and outbuildings — sit outside the main central heating loop, run hot in summer and cold in winter. A single 2.5kW reversible split turns them into year-round usable space for £1,500-£1,800.
Converted lofts have decent insulation but poor airflow — they overheat in summer and feel stuffy in winter. A single split or a discreet ducted unit gives year-round comfort. Particularly common request from clients with teenagers in loft conversions.
South-facing extensions and conservatories often run 8-12°C above the rest of the house on sunny afternoons. A 3.5-5kW split or ceiling cassette handles cooling on demand and provides shoulder-season heating.
Modern well-insulated homes can run 22-25°C upstairs through summer nights even with windows open. A bedroom split at 19-20°C with whisper-mode fan delivers proper sleep quality. Daikin Stylish or Mitsubishi MSZ-LN are common premium choices for aesthetics.
Large open-plan ground-floor extensions with high-glass elevations are the hardest spaces to heat and cool with traditional radiators alone. A wall-mounted or ceiling cassette air conditioning unit handles both functions efficiently.
For larger homes or homes built without central heating to current standards, a 4-6 unit multi-zone install gives full per-room control. More common in detached homes with high glass-to-wall ratios.
Air conditioning cost
A single-room reversible split system in the UK costs between £1,500 and £2,200 fully fitted in 2026. Multi-room and whole-home configurations scale up from there. Per indoor unit, the marginal cost falls — adding a second indoor unit to an existing outdoor compressor is typically £800-£1,200.
| Configuration | Capacity | Fitted price | Install time |
|---|---|---|---|
| Single-room split (bedroom or home office) | 2.5-3.5kW indoor | £1,500-£2,200 | 1 day |
| Two-room multi-split | 5-7kW outdoor + 2 indoor | £2,800-£3,800 | 1-2 days |
| Three-room multi-split | 7-10kW outdoor + 3 indoor | £3,800-£5,500 | 2 days |
| Whole-home multi-zone (4+ rooms) | 10-16kW outdoor + 4-6 indoor | £5,500-£9,500 | 2-3 days |
| Ducted concealed system (luxury fit) | Various | £6,500-£14,000 | 3-5 days |
Prices fitted include indoor and outdoor units, refrigerant piping, condensate drain, electrical connection, F-Gas commissioning, system handover, manufacturer warranty registration. Outdoor unit siting beyond standard installation distance (e.g. roof-mounted) and conservation-area consent applications quoted in advance.
Brand comparison
Both brands are top-tier and we install both. They share similar reliability, similar warranty length (5-7 years), similar efficiency ratings. The genuine differences are aesthetic and slightly performance-specific:
Daikin
Slightly quieter at low-fan speeds. The Daikin Stylish indoor unit (designed by Pininfarina) is the best-looking residential indoor unit on the market — favoured for living rooms and bedrooms where the unit is visible. Marginally stronger on heating mode efficiency at low outdoor temperatures (UK-relevant).
Mitsubishi Electric
Slightly stronger cooling capacity at high outdoor temperatures. The MSZ-LN range matches the Daikin Stylish for premium aesthetics. Industry standard for multi-split and ducted installs — broader range of indoor unit types (wall-mount, ceiling cassette, ducted, console, floor-standing).
For most residential installs, the brand choice comes down to indoor unit aesthetics and current pricing — both deliver reliable long-term operation. We default to whichever brand is best stocked and competitively priced at quote time unless you have a specific preference.
Compliance & aftercare
Domestic air conditioning systems contain F-Gas refrigerants regulated under UK F-Gas law. All install and service work must be done by an F-Gas registered engineer — which we are. The systems we install use R32 refrigerant, with dramatically lower global warming potential than the older R410A still found in some legacy units.
Domestic systems below 3kg of refrigerant don't require statutory annual inspection. An annual service keeps efficiency high and warranty valid. We offer service contracts at £120-£180/year depending on number of indoor units.
Indoor unit filters are user-cleanable — slide out, vacuum or rinse, slide back. Should be cleaned every 2-3 months in regular use. Failure to clean filters is the single biggest avoidable cause of system underperformance.

Works best together
Air conditioning units use electricity — solar PV makes them effectively free to run on summer afternoons (the exact time you want them on). Battery storage extends the same benefit into evening cooling and the heating-mode shoulder-season hours.
Summer afternoons are peak AC demand AND peak solar generation — they overlap almost perfectly. Solar can cover most cooling demand without grid draw. The classic "free cooling" pairing.
See solar panels →Battery captures daytime solar surplus and powers your AC into the evening — or charges overnight on cheap tariff and powers AC during the working day. Either way, slashes the cost of cooling.
See home battery storage →For year-round heating, an air-to-water heat pump beats AC for whole-home heating. AC complements it in problem rooms (extensions, lofts) where the heat pump alone won't suffice.
