How much does it cost to replace air conditioning in Dorset?
Our guide range in Dorset is £1,695–£4,650 per indoor unit before VAT; a typical job (replacing a 3–4 unit system, re-using sound pipework) is £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.

Install and commission
New units are fitted, tested and commissioned with fresh records.
Points to plan for in Dorset
R22
Since 1 January 2015, R22 systems cannot be maintained using virgin or recycled R22. If one leaks, the practical fix is usually replacement.
Working hours
Most Dorset businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Downtime
We schedule the swap to keep the space usable, often over a weekend.
Access and parking
Town-centre jobs in Dorset often come down to access — loading restrictions, parking for the van and getting equipment onto a roof. We check this at survey and plan deliveries around it.
Typical premises in Dorset
- Healthcare and dental: clean, quiet cooling for surgeries, clinics, dental practices and care settings.
- Warehouses and industrial: cooling for offices, mezzanines, control rooms and temperature-sensitive areas.
- Restaurants and cafés: dining rooms that stay comfortable next to a hot kitchen and a busy service.
- Salons and spas: comfortable salons and treatment rooms despite dryers, lamps and steam.
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.
Questions about replacement and upgrades in Dorset
How much does it cost to replace air conditioning in Dorset?
Guide prices in Dorset 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) costs £6,195–£15,095 plus VAT. We fix the price in writing after a free survey.
Do you also cover the Isle of Wight, Hampshire and Wiltshire?
Yes. Alongside Dorset, we also cover the Isle of Wight, Hampshire and Wiltshire. Each has its own page with local guide prices.
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.
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.
