Leak detection and regassing in Chelmsford
If a system in Chelmsford has needed gas before, the original leak was probably never fixed. The East of England is one of the sunniest and driest parts of the UK, which makes glazed rooms and lofts hard to keep cool.
If an older system in your Chelmsford home uses R22, replacement is usually the route, because it can no longer be recharged. Chelmsford sits around 17 miles from Southend-on-Sea, inside our Essex area. We cover CM1 and the streets around them.
