Budget roughly £1,595–£4,350 per indoor unit ex VAT in Preston. For a typical job — replacing a 3–4 unit system, re-using sound pipework — expect £5,850–£14,195 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.

Before you book in Preston
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 Preston 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.
Disposal
Old refrigerant must be recovered by certified engineers and the units disposed of as waste electrical equipment.
Working hours
Most Preston businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.

Questions about replacement and upgrades in Preston
How much does it cost to replace air conditioning in Preston?
Guide prices in Preston run from about £1,595 to £4,350 per indoor unit, plus VAT. A typical job (replacing a 3–4 unit system, re-using sound pipework) costs £5,850–£14,195 plus VAT. We fix the price in writing after a free survey.
Do you also cover Leyland, Chorley and Blackburn?
Yes. Alongside Preston, we also cover Leyland, Chorley and Blackburn. Each has its own page with local guide prices.
Which postcodes do you cover in Preston?
All of them, including BN1, CO10, CT3 and DT3. Give us your postcode when you enquire and we will confirm the visit details.
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.
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.
