Deep clean and odour treatment in Watford
A musty smell on start-up is the most common sign that an indoor unit in Watford needs a deep clean. Bright summers in the East of England mean solar gain through glass is usually the biggest load to design for.
Homes near busy roads and kitchens around Watford tend to need a deep clean more often. We cover Watford and the rest of Hertfordshire, including Hemel Hempstead and Stevenage. We cover WD1, WD17, WD18, WD19, WD24 and WD25 and the streets around them.

Permissions
Cleaning the indoor unit is not refrigerant work. Anything the engineer finds beyond the clean, such as a leak or a failing fan, is explained and priced before it is touched.
The visit
Visits in Watford are booked at a price agreed with you in advance. If the engineer finds anything beyond the agreed work, they explain it and price it before carrying it out. We agree the visit price before we come. On the day the engineer checks the system, carries out the agreed work and talks you through anything they find.
