Leak detection and regassing in St Helens
Damp North West weather makes the dehumidifying mode of a modern split system genuinely useful for much of the year. If an older system in your St Helens home uses R22, replacement is usually the route, because it can no longer be recharged.
If a system in St Helens has needed gas before, the original leak was probably never fixed. Our Merseyside coverage takes in St Helens, about 10 miles from Liverpool. Postcode districts we cover here include WA10.
