How much does it cost to replace air conditioning in Finchley?

Air conditioning replacement is removing an old system — often one using R22 or R410A refrigerant — and installing new, more efficient equipment, re-using pipework where it is safe and compatible.
Working in Finchley
Premises in Finchley are often in mixed-use buildings with shared roofs and tight access, so outdoor unit positions are agreed early.
We work across Finchley's postcode districts, including N3. We also work in nearby Golders Green, Muswell Hill and Cricklewood. In Finchley, outdoor unit positions are often the deciding factor: a rear flat roof or yard is usually straightforward, while a front elevation may need landlord or planning consent first.

How a job in Finchley works
Survey
We record what is installed, its condition and refrigerant, and what can be re-used. For sites in Finchley we confirm access and parking beforehand.

Install and commission
New units are fitted, tested and commissioned with fresh records.
Local points to consider
Disposal
Old refrigerant must be recovered by certified engineers and the units disposed of as waste electrical equipment.
Neighbours and noise
Outdoor units near flats — common above shops — need careful siting so noise at neighbours' windows stays low. We choose positions and quieter units with that in mind.
R22
Since 1 January 2015, R22 systems cannot be maintained using virgin or recycled R22. If one leaks, the practical fix is usually replacement.
Conservation areas
Historic streets and listed buildings in and around Finchley are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.

Will a new system be cheaper to run?
Usually. Modern inverter systems are considerably more efficient than equipment from 15–20 years ago, though savings depend on use.
Is it illegal to use R22 air conditioning?
No — you can keep running an R22 system, but it cannot be maintained with virgin or recycled R22, so most repairs involving the refrigerant circuit are no longer possible.
