Deep clean and odour treatment across Cumbria
If an indoor unit in Carlisle 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 Carlisle needs a deep clean. Milder summers in the North West mean designing for winter comfort as much as for a heatwave.
Prices in Cumbria
In North West England, our guide range for a deep clean and odour treatment is £140–£235 per indoor unit, including VAT. 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
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
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. Visits in Cumbria 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.
