Deep clean and odour treatment across County Durham
If an indoor unit in Durham drips from the front, a blocked drain tray is often the cause, which a deep clean clears. Homes near busy roads and kitchens around Durham tend to need a deep clean more often. In the North East, sizing for winter heating and then checking summer cooling usually gives the right system.
