Deep clean and odour treatment across Surrey
Homes near busy roads and kitchens around Woking tend to need a deep clean more often. A musty smell on start-up is the most common sign that an indoor unit in Woking needs a deep clean. In the South East, loft rooms and glazed extensions can climb well above the outside temperature on a sunny afternoon.
Prices in Surrey
Budget around £175–£300 per indoor unit including VAT for a deep clean and odour treatment in and around Surrey. That is above the UK middle, mainly because labour and access cost more in South East England. More indoor units, heavy build-up on the fan or a blocked drain line are what move the price towards the upper figure. 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
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
Visits in Surrey 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. 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.
