Deep clean and odour treatment in Cheltenham
In the South West, a system that heats well through damp winters is often as valuable as summer cooling. A musty smell on start-up is the most common sign that an indoor unit in Cheltenham needs a deep clean.
Homes near busy roads and kitchens around Cheltenham tend to need a deep clean more often. Cheltenham lies roughly 7 miles from Gloucester, and we cover it as part of Gloucestershire. Coverage includes GL50 and GL52.
Prices in Cheltenham
For Cheltenham, expect roughly £145 to £245 per indoor unit, VAT included, adjusted for typical South West England rates. That is broadly in line with national guide prices. More indoor units, heavy build-up on the fan or a blocked drain line are what move the price towards the upper figure. Typical Two units work (deep clean of two indoor units on one visit) lands around £265–£445 in this area.
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
A deep clean does not touch the refrigerant circuit and needs no permissions. If the engineer finds a refrigerant problem, it is explained and priced separately before anything is done.
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 Cheltenham 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.
