It isn’t just cold air.

NVK Air installs new air conditioning and air to air heat pumps in Harrow, Stanmore and across London, from £1,995 fully installed. We are based in Harrow and Stanmore, and the towns around them, from Kenton, Pinner and Edgware to Wembley, Ruislip, Watford and Bushey, each have a page of their own under Areas we cover. We fit Daikin, Samsung and Mitsubishi Heavy Industries wall mounted systems. We are a REFCOM certified company (REF1025662), SafeContractor approved (MD8663) and fully insured, and all refrigerant work is done by an F-Gas Category 1 qualified engineer. We install new systems: we are not a repair or breakdown service.

Daikin, Samsung and Mitsubishi Heavy Industries, in six ranges: Samsung Cebu S2 from £1,995, Mitsubishi Heavy Industries ZS from £2,150, Daikin Comfora from £2,195, Samsung WindFree Comfort S2 from £2,295, Daikin Perfera from £2,300, Daikin Stylish from £2,500. Every price is fully installed and includes the unit, the installation, the electrical work and VAT. The Daikin Comfora is the one we hold in stock, which is why it is the quickest to get fitted. Every one of them heats as well as cools. The compare page sets them side by side on size, sound level and finish, using each manufacturer's own published figures.

Every install is backed by our 12 month parts and labour warranty, on top of the manufacturer's warranty on your unit, which we register for you at handover. That workmanship warranty covers the installation itself: the pipework, the electrical connection, the brackets and the commissioning. The manufacturer's warranty covers the unit and its parts, and registering it at handover means you do not have to remember to do it. If something is not right, you call 020 3822 0118 and we come back. We are a REFCOM certified company, registration REF1025662, and all refrigerant work is done by an F-Gas Category 1 qualified engineer, so it is recorded properly and stays compliant. Our full terms, including your 14 day right to cancel, are on the terms page of this website.

Call 020 3822 0118 and we come back. We fit new systems, and every one is covered by our 12 month parts and labour warranty on top of the manufacturer's warranty on the unit. Manufacturer warranties generally set out a servicing interval and expect it to have been kept to, so it is worth reading the terms that come with your unit at handover.

The unit, up to 3m of pipework, external trunking, a bracket or feet for the outdoor unit, a gravity drain, the electrical connection by a qualified electrician, commissioning and a handover pack. That is one number, agreed before any work starts. The prices shown are starting prices for a standard installation. If your job needs a longer pipe run, internal boxed trunking, a condensate pump, an old system removed, or access above the first floor, we price it in your quote so you see it before you agree, never on the day. The exact figure comes from a free survey.

Yes. Every unit we fit is a heat pump as well as an air conditioner, so the same box on the wall cools the room in summer and heats it in winter. In heating mode it moves heat in from outside rather than burning anything, which is why a heat pump delivers several units of heat for each unit of electricity it uses. In practice it means one system for the whole year instead of a fan in summer and a heater in winter, controlled from a remote or an app, and reaching temperature quickly because it heats the air directly.

Start with the instant estimate on this page. Four questions about the room, its size, the floor it is on and anything unusual, and you get the recommended size and a starting price straight away. For the exact figure, call 020 3822 0118 or request a callback and we book a free survey. On the survey we check the room, agree where the unit goes, look at the route for the pipework and the outdoor position, and confirm the electrical supply. You then get one written number covering everything, from £1,995 for a 2.5kW up to £3,395 for a 7.1kW, agreed before work starts.
