Leak detection and regassing in Mold
North Wales has mild, damp weather for much of the year, so efficient heating and dehumidifying are big benefits. If an older system in your Mold home uses R22, replacement is usually the route, because it can no longer be recharged.
If a system in Mold has needed gas before, the original leak was probably never fixed. Mold lies roughly 10 miles from Wrexham, and we cover it as part of Clwyd. Postcode districts we cover here include CH7.
Prices in Mold
Our North Wales guide price for leak detection and regassing is £230–£945 leak find, repair and recharge, VAT included. It is a touch below the UK middle, as trade rates in North Wales tend to be. Access, the number of indoor units and any parts are what move the price, and we confirm it before booking. For reference, the Standard option in Mold (leak in pipework or valve, full recharge) usually comes to about £370–£595.
