Room guide
Air conditioning for your home office
Working from a spare room or box room that turns into an oven by midday, or a cold corner that never warms up properly in winter, makes it hard to concentrate. A wall-mounted air conditioning unit cools the room in summer and heats it in winter, so your home office stays comfortable whatever the season.
What size do you need?
A home office does not get its own line in our size guide, so we use the nearest match: a small office is treated the same as a standard bedroom (2.5kW), and a larger office, or one that also holds a desktop PC, printer and other equipment giving off heat, is closer to our large bedroom or standard living room size (3.5kW). We check the right size for your room at a free survey.
Noise during calls and meetings
Samsung publishes indoor noise of 19 to 36 dB(A), from the quietest setting to the fan on full, for the 2.5kW WindFree Comfort on our Bronze package. That quietest figure sits well below normal speaking volume. For the other packages, we can go through each manufacturer's figures with you at your free survey.
| Package | System | Price (2.5kW) | Parts warranty |
|---|---|---|---|
| Budget | Haier Revive Plus | £1,585 | 3-year parts warranty |
| Bronze | Samsung WindFree Comfort | £1,805 | 7-year parts warranty |
| Silver | Fujitsu Standard KM White | £1,855 | 5-year parts warranty |
| Gold (recommended) | Mitsubishi Heavy Industries Premium ZS White | £2,040 | 10-year parts warranty |
| Platinum | Daikin Perfera White | £2,145 | 3-year parts warranty |
| Elite | Daikin Stylish White | £2,505 | 3-year parts warranty |
Prices shown are fully supplied, installed, tested and commissioned for a 2.5kW system, including VAT. The Budget package's smallest Haier Revive Plus is rated 2.7kW.
Running costs
Running cost depends on room size, insulation, how hard the unit is working and how long it runs each working day. We cannot give you a single running cost figure for every office, because it depends on your equipment and the room, but the same Ofgem electricity price cap that applies to the rest of your home applies here too, so a well-insulated room on a moderate setting will always cost less to run than a large, sun-facing room on full power all day.
Which package suits a home office?
Budget (Haier Revive Plus) is a sensible, affordable choice for most offices, with a 3-year parts warranty. Silver (Fujitsu Standard KM White) is a small step up with a 5-year parts warranty. Gold, our recommended package, is the Mitsubishi Heavy Industries Premium ZS White with a 10-year parts warranty, which suits a room you use every working day. Bronze, Platinum and Elite are also available if you prefer Samsung's WindFree no-draught cooling or a Daikin system.

Questions about home office air conditioning
Short answers to what people ask us most.
All questions answeredWhat size air conditioner does a home office need?
It depends on the room. Our size guide treats a small office the same as a standard bedroom, which is a 2.5kW system. A bigger office, or one with a lot of equipment and window, is closer to our large bedroom or standard living room size, which is 3.5kW. We measure the room at your free survey.
Will air conditioning be quiet enough for video calls?
Samsung lists the 2.5kW WindFree Comfort on our Bronze package at 19 dB(A) indoors on its quietest setting, which is quiet enough that most people take calls without turning it off. We can go through the manufacturer's figures for the other packages at your survey. On a higher fan speed, during a hot afternoon, any unit is more noticeable, so most people turn it down before a call.
Can the same unit heat my office in winter?
Yes. Every package we fit is a heat pump, so the same wall-mounted unit cools the room in summer and heats it in winter, from one piece of equipment.
Where does the indoor unit go in a small office?
Usually on the wall facing your desk or above a doorway, away from directly behind your monitor so the airflow does not blow papers around or dry your eyes out while you work. Our engineer checks this at survey.
