Deep clean and odour treatment in Horsham
Summers in the South East are among the warmest in the country, so cooling often comes first, with efficient winter heating as a bonus. A musty smell on start-up is the most common sign that an indoor unit in Horsham needs a deep clean.
Homes near busy roads and kitchens around Horsham tend to need a deep clean more often. Horsham lies roughly 7 miles from Crawley, and we cover it as part of West Sussex. Homes in RH12 are all within our coverage.
Prices in Horsham
A deep clean and odour treatment in Horsham typically comes in at £175–£300 per indoor unit including VAT, based on South East England rates. South East England is one of the dearer parts of the UK for trades, which shows in the range. 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 £325–£545 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
No planning or F-gas work is involved in a deep clean, though the engineer will tell you if the system shows signs of a refrigerant leak.
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. 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.
