How much does it cost to replace air conditioning in Christchurch?
In Christchurch, guide prices run from about £1,695 to £4,650 per indoor unit, plus VAT. A typical job (replacing a 3–4 unit system, re-using sound pipework) usually comes to £6,195–£15,095 plus VAT. The fixed price follows a free survey.
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.
Where we work around Christchurch
In Christchurch, typical premises are high-street shops, offices above them, surgeries, salons and local industrial units. Bournemouth is about 7 km away.
We work across Christchurch's postcode districts, including BH23, GL16 and PE14. We also cover Bournemouth, New Milton and Poole, all within easy reach of Christchurch. Buildings across Dorset range from converted period offices to modern units with deep ceiling voids, so we measure each site rather than relying on a standard package.
Included as standard
- Condition survey of the existing system
- Pipework re-use assessment, flushing where suitable
- Refrigerant recovery with waste transfer documentation
- Installation of new efficient units
- Commissioning and new F-gas records

Points to plan for in Christchurch
Downtime
We schedule the swap to keep the space usable, often over a weekend.
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.
Pipe re-use
Re-use depends on pipe size, condition, cleanliness and the new refrigerant. We test before relying on it.
Leased premises
If your Christchurch premises are leased, the landlord's written consent is usually needed for external units, wall penetrations and roof access. We provide drawings and data sheets for the request.
Typical premises in Christchurch
- 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.
- Schools and education: classroom cooling, ventilation and IT room cooling, installed in the holidays.
- Warehouses and industrial: cooling for offices, mezzanines, control rooms and temperature-sensitive areas.
Two rules matter for most businesses in England: GB F-gas rules (leak checks from 5 tonnes CO2e) and the periodic energy inspection for more than 12 kW of air conditioning.

Should we replace R410A systems now?
Not necessarily. If an R410A system is working well and maintained, keep it. Plan replacement when it becomes unreliable or expensive to run.

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.
