Common questions
Do you stock Alliance parts in Dainfern Golf Estate?
Yes. Alliance is locally supported, so boards, sensors, capacitors and fan motors are available quickly, which keeps repair times short.
How often should an aircon need re-gassing?
A correctly installed system should never need gas. If it does, there is a leak, so we pressure test and repair the leak before charging rather than topping up annually.
Do you work inside gated estates?
Regularly. Technician details, ID numbers and vehicle registration are submitted to the HOA or gatehouse before the appointment so access is cleared in advance.
