Deep clean and odour treatment across Devon
A musty smell on start-up is the most common sign that an indoor unit in Plymouth needs a deep clean. Homes near busy roads and kitchens around Plymouth tend to need a deep clean more often. In the South West, a system that heats well through damp winters is often as valuable as summer cooling.
Prices in Devon
A deep clean and odour treatment in Devon typically comes in at £145–£245 per indoor unit including VAT, based on South West England rates. That is close to the UK middle for this kind of work. More indoor units, heavy build-up on the fan or a blocked drain line are what move the price towards the upper figure. 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
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. Visits in Devon 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.
