Deep clean and odour treatment across Merseyside
A musty smell on start-up is the most common sign that an indoor unit in Liverpool needs a deep clean. Homes near busy roads and kitchens around Liverpool tend to need a deep clean more often. North West summers are cooler, so many systems here earn their keep as efficient heaters, with cooling for the warmest weeks.
Prices in Merseyside
Budget around £140–£235 per indoor unit including VAT for a deep clean and odour treatment in and around Merseyside. Labour rates in North West England keep this slightly under the national middle. 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 £250–£395 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
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.
