Deep clean and odour treatment in Guildford
The South East sees some of the UK's warmest summer days, and south-facing rooms and conservatories feel it first. If an indoor unit in Guildford 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 Guildford needs a deep clean. Guildford sits around 6 miles from Woking, inside our Surrey area. That includes the GU1 postcode district.
Prices in Guildford
For Guildford, expect roughly £175 to £300 per indoor unit, VAT included, adjusted for typical South East England rates. 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. On our South East England figures, the Two units option (deep clean of two indoor units on one visit) is about £325–£545.
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
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. 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.
