Deep clean and odour treatment across West Sussex
A musty smell on start-up is the most common sign that an indoor unit in Crawley needs a deep clean. If an indoor unit in Crawley drips from the front, a blocked drain tray is often the cause, which a deep clean clears. In the South East, loft rooms and glazed extensions can climb well above the outside temperature on a sunny afternoon.
Prices in West Sussex
Guide prices around West Sussex run from £175 to £300 per indoor unit including VAT. That is above the UK middle, mainly because labour and access cost more in South East England. The price depends mainly on how many indoor units need cleaning and whether the fan and coil need a full strip-down. As an example, the Two units option (deep clean of two indoor units on one visit) would typically be £325–£545 here.
One unit
Deep clean of a single indoor unit.
Two units
Deep clean of two indoor units on one visit.
Clean and service
Deep clean plus a full service of the system.
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
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.
