Leak detection and regassing in Merthyr Tydfil
If an older system in your Merthyr Tydfil home uses R22, replacement is usually the route, because it can no longer be recharged. Wet South Wales winters make a heat pump's quiet, even heating and dehumidifying mode useful well beyond summer.
If a system in Merthyr Tydfil has needed gas before, the original leak was probably never fixed. Merthyr Tydfil lies roughly 19 miles from Bridgend, and we cover it as part of Mid Glamorgan. Homes in CF47 are all within our coverage.
