Disposal
Old refrigerant must be recovered by certified engineers and the units disposed of as waste electrical equipment.
Leased premises
If your County Londonderry 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.
R22
Since 1 January 2015, R22 systems cannot be maintained using virgin or recycled R22. If one leaks, the practical fix is usually replacement.
Access and parking
Town-centre jobs in County Londonderry 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.

Compliance in Northern Ireland: refrigerant work falls under EU F-gas rules that apply in Northern Ireland, and buildings with more than 12 kW of air conditioning in total need a periodic energy inspection (often called TM44).

Guide prices in County Londonderry 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.
Do you also cover County Tyrone, County Antrim and County Armagh?
Yes. Alongside County Londonderry, we also cover County Tyrone, County Antrim and County Armagh. 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.
What happens to the old refrigerant?
It is recovered into certified cylinders and sent for reclamation or destruction, with the paperwork kept on your records.
