Air Conditioning

Air conditioning keeps a room cool on hot days and warm on cold ones. We fit wall-mounted units in homes across Derby and Derbyshire. Josh is F-gas certified, and the electrical supply is included, tested and certified. Here's what you get, what it costs and how it works.

What you get

A split system has two parts. The indoor unit sits high on the wall and blows cool or warm air into the room. The outdoor unit sits outside, on a wall or on the ground. A short pipe run through the wall joins them, carrying the refrigerant pipes, the cable and a small drain for the water the unit takes out of the air.

It's a heat pump, so the same unit cools in summer and heats in winter. Modern wall units are quiet, and Wi-Fi models let you switch them on from your phone before you get home.

The kind of unit we fit

For a single room we fit units such as the Haier Revive 3.2 kW (indoor unit AS35RBAHRA-4 with outdoor unit 1U35YESFRA-4), a wall-mounted split heat pump:

• 3.2 kW of cooling (0.8 to 3.8 kW)
• 3.9 kW of heating (0.7 to 4.0 kW)
• R32 refrigerant and an A++ seasonal efficiency rating
• Wi-Fi control through Haier's hOn app, and by voice through smart speakers
• Self-cleaning: it heats the coil to 56°C for 30 minutes, and it can freeze the coil and wash the dust off as it thaws
• An iFeel remote, which senses the temperature where you're sitting rather than up at the unit

We recommend the right unit for your room at the visit.

What the starting price covers

The £1,495 starting price is for one room with a back-to-back system (the indoor unit on an outside wall, with the outdoor unit directly behind it outside), up to 3 metres of pipework and trunking, and power from a local fused circuit. Anything beyond that, such as a longer pipe run or the outdoor unit somewhere else, we look at during the free visit and put in your written quote, so you know the full figure before we start.

Who fits it

Air conditioning work involves handling refrigerant gas, which by law needs F-gas certification. Josh holds an F-gas certificate, a brazing qualification (for joining the copper refrigerant pipes) and training in air conditioning, and he's a member of REFCOM, which certifies businesses under the F-gas regulations. The electrical side is done by the same NAPIT-registered team that does all our electrical work.

How it works

1. A free visit. We look at the room, where the outdoor unit can go, and the route for the pipes and the drain.
2. A written quote. The unit, the work and the price, in writing.
3. Installation. The indoor unit, the outdoor unit and the pipe run between them, fitted neatly.
4. The electrical supply, certified. We power the unit from a local fused circuit, then test the electrical work and certify it to BS 7671.
