What to think about in Carrickfergus
Pipe re-use
Re-use depends on pipe size, condition, cleanliness and the new refrigerant. We test before relying on it.
Working hours
Most Carrickfergus businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Disposal
Old refrigerant must be recovered by certified engineers and the units disposed of as waste electrical equipment.
Leased premises
If your Carrickfergus 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.

Questions about replacement and upgrades in Carrickfergus
How much does it cost to replace air conditioning in Carrickfergus?
Guide prices in Carrickfergus run from about £1,500 to £4,095 per indoor unit, plus VAT. A typical job (replacing a 3–4 unit system, re-using sound pipework) costs £5,450–£13,350 plus VAT. We fix the price in writing after a free survey.

Which postcodes do you cover in Carrickfergus?
All of them, including BT38. Give us your postcode when you enquire and we will confirm the visit details.
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.
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.
