[See more of our installations](https://climateshieldlondon.co.uk/installations/) We install, service and repair air conditioning across Whetstone N20. A single room is £2,400 to £3,200 fitted and a whole house is £8,400 to £11,300, with a free survey and a written price that does not change. Two or three rooms on one outdoor unit, condenser at ground level against the flank wall, each room on its own indoor unit and its own control. One to two days on site. ### What the housing in Whetstone means for the job N20 is mostly interwar semi-detached and detached housing with real gardens, which is the straightforward end of London installing: side access, room for a proper base, and a boundary far enough away that noise is somebody's preference rather than a problem. Towards Totteridge the houses get considerably bigger, and a whole-house system there is four or five indoor units rather than one or two, with the condenser sized for all of them running at once. Along the High Road there are newer flats and a run of small commercial premises, which is a different job again. **Worth knowing before you book.** On the larger houses the mistake is sizing the condenser for the rooms people use rather than for all of them at once. If the plan is to add a room later, it is far cheaper to size for it now. **Nearest postcodes we also cover:** [Cockfosters and East Barnet EN4](https://climateshieldlondon.co.uk/air-conditioning-cockfosters-en4/), 1.3 miles; [North Finchley N12](https://climateshieldlondon.co.uk/air-conditioning-north-finchley-n12/), 1.5 miles; [Southgate N14](https://climateshieldlondon.co.uk/air-conditioning-southgate-n14/), 2.1 miles.

Up to a point. One condenser runs several indoor units, but every room still needs its own unit and the condenser has to be sized for all of them together. A whole four-bedroom house is £8,400 to £11,300 fitted and including VAT, from our own quotations. ### How far is Whetstone from you? We are in N14, so N20 is a short run across the north of the borough. Surveys inside 48 hours are normal and there is no travel charge. [The Barnet page](https://climateshieldlondon.co.uk/air-conditioning-barnet/) covers the rest of the borough. ### Do you work on the bigger Totteridge houses? Yes, and they are some of our better jobs: space for the plant, a real electrical supply and rooms that justify doing it properly. The same team fits heat pumps and solar, so if the house is being done anyway it is worth pricing them together. ## Book a free survey in Whetstone A surveyor measures the rooms, checks the electrics and the outdoor position, and writes a fixed price.
