Leak detection and regassing in South Croydon
If an older system in your South Croydon home uses R22, replacement is usually the route, because it can no longer be recharged. London's dense streets hold heat overnight, so top-floor flats and loft rooms often stay warm long after sunset.
Flare joints are a frequent leak point on older split systems, so they are among the first things checked on a visit in South Croydon. South Croydon sits around 10 miles from central London, inside our London area. That includes the CR7 and CR9 postcode districts.
