Deep clean and odour treatment in St Albans
Bright summers in the East of England mean solar gain through glass is usually the biggest load to design for. If an indoor unit in St Albans drips from the front, a blocked drain tray is often the cause, which a deep clean clears.
Homes near busy roads and kitchens around St Albans tend to need a deep clean more often. St Albans is about 7 miles from Watford and falls within our Hertfordshire coverage. Coverage includes AL1 and AL3.

Permissions
A deep clean does not touch the refrigerant circuit and needs no permissions. If the engineer finds a refrigerant problem, it is explained and priced separately before anything is done.
The visit
A photo of the indoor unit's label and a short description of the problem help us price the visit accurately and bring what is likely to be needed. Before booking, tell us the make and model and what the system is doing. We confirm the visit price, then the engineer arrives with the right equipment and, where possible, the right parts.
