Leak detection and regassing in Coulsdon
If an older system in your Coulsdon home uses R22, replacement is usually the route, because it can no longer be recharged. The urban heat island effect means London bedrooms can stay uncomfortably warm on summer nights.
If a system in Coulsdon has needed gas before, the original leak was probably never fixed. Coulsdon is about 12 miles from central London and falls within our London coverage. Coverage includes CR5.
