What to think about in County Londonderry
Old refrigerant
Systems still on R22 cannot legally be topped up with virgin or recycled R22. Repairs on these are limited — replacement is often the realistic option.
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.
Repeat failures
If a system has failed several times, we compare the cost of repair against replacement.
Conservation areas
Historic streets and listed buildings in and around County Londonderry are more likely to need planning permission for outdoor units on visible elevations. We check with the council's planning service before work is booked.
