How much does it cost to replace air conditioning in Chesham?
Our guide range in Chesham is £1,895–£5,095 per indoor unit before VAT; a typical job (replacing a 3–4 unit system, re-using sound pipework) is £6,850–£16,695 plus VAT. Your exact price is fixed in writing once we have surveyed.
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 Chesham
Most commercial premises in and around Chesham are shops, offices, salons, pubs and small industrial units. High Wycombe is about 13 km away.
That includes premises in HP5 and the surrounding districts. We also work in nearby Amersham, Berkhamsted and Chalfont St Peter. Buildings across Buckinghamshire range from converted period offices to modern units with deep ceiling voids, so we measure each site rather than relying on a standard package.
What we do
- Condition survey of the existing system
- Pipework re-use assessment, flushing where suitable
- Refrigerant recovery with waste transfer documentation
- Removal and disposal of old equipment
- Commissioning and new F-gas records

From enquiry to handover in Chesham
Survey
We record what is installed, its condition and refrigerant, and what can be re-used.
Plan the swap
Removal and installation are scheduled to keep downtime short.
Recover and remove
Refrigerant is recovered into certified cylinders and the old units removed. We keep work areas in Chesham screened and tidy at the end of each day.
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.
Conservation areas
Historic streets and listed buildings in and around Chesham are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
R22
Since 1 January 2015, R22 systems cannot be maintained using virgin or recycled R22. If one leaks, the practical fix is usually replacement.
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.
Who we work with in Chesham
- Salons and spas: comfortable salons and treatment rooms despite dryers, lamps and steam.
- Healthcare and dental: clean, quiet cooling for surgeries, clinics, dental practices and care settings.
- Restaurants and cafés: dining rooms that stay comfortable next to a hot kitchen and a busy service.
- Offices: zoned cooling and heating for open-plan floors, meeting rooms and comms rooms.
In England, systems holding 5 tonnes CO2 equivalent of refrigerant or more fall under GB F-gas rules, with regular leak checks and records; buildings with more than 12 kW of air conditioning in total also need a periodic energy inspection.

Which postcodes do you cover in Chesham?
All of them, including HP5. Give us your postcode when you enquire and we will confirm the visit details.
Can existing pipework be re-used?
Often, if it is the right size, in good condition and compatible with the new refrigerant. We test and flush it before relying on it.
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.
