Deep clean and odour treatment across Cornwall
Homes near busy roads and kitchens around Truro tend to need a deep clean more often. A musty smell on start-up is the most common sign that an indoor unit in Truro needs a deep clean. Coastal breezes help, but inland South West towns and glazed rooms still see uncomfortable peaks.
Prices in Cornwall
In South West England, our guide range for a deep clean and odour treatment is £145–£245 per indoor unit, including VAT. That is close to the UK middle for this kind of work. 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 £265–£445 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
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. 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.
