Deep clean and odour treatment across the West Midlands
If an indoor unit in Birmingham drips from the front, a blocked drain tray is often the cause, which a deep clean clears. A musty smell on start-up is the most common sign that an indoor unit in Birmingham needs a deep clean. In the West Midlands, sizing for winter heating first and then checking summer cooling usually gives the best all-year system.
Prices in the West Midlands
In the West Midlands, our guide range for a deep clean and odour treatment is £140–£240 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. On our West Midlands figures, the Two units option (deep clean of two indoor units on one visit) is about £260–£445.
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 the West Midlands 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.
