Deep clean and odour treatment in Farnborough
Hot spells reach the South East early, which makes spring the easiest time to arrange an installation. If an indoor unit in Farnborough 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 Farnborough needs a deep clean. Farnborough is about 39 miles from Southampton and falls within our Hampshire coverage. Homes in GU11 are all within our coverage.
Prices in Farnborough
In South East England, our guide range for a deep clean and odour treatment is £175–£300 per indoor unit, including VAT. 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. Typical Two units work (deep clean of two indoor units on one visit) lands around £325–£545 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
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. 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.
