Deep clean and odour treatment in Winchester
In the South East, loft rooms and glazed extensions can climb well above the outside temperature on a sunny afternoon. Homes near busy roads and kitchens around Winchester tend to need a deep clean more often.
A musty smell on start-up is the most common sign that an indoor unit in Winchester needs a deep clean. Winchester sits around 12 miles from Southampton, inside our Hampshire area. We cover SO23 and SO25 and the streets around them.
Prices in Winchester
Our South East England guide price for a deep clean and odour treatment is £175–£300 per indoor unit, VAT included. Prices here sit above the national middle, reflecting South East England labour rates and parking and access costs. The price depends mainly on how many indoor units need cleaning and whether the fan and coil need a full strip-down. Typical Two units work (deep clean of two indoor units on one visit) lands around £325–£545 in this area.

Two units
Deep clean of two indoor units on one visit.
Clean and service

Permissions
No planning or F-gas work is involved in a deep clean, though the engineer will tell you if the system shows signs of a refrigerant leak.
The visit
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. 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.
