Deep clean and odour treatment across County Down
Homes near busy roads and kitchens around Bangor tend to need a deep clean more often. A musty smell on start-up is the most common sign that an indoor unit in Bangor needs a deep clean. Damp Northern Ireland winters make a heat pump's dehumidifying mode useful well beyond the summer.
Prices in County Down
In Northern Ireland, our guide range for a deep clean and odour treatment is £135–£225 per indoor unit, including VAT. It is a touch below the UK middle, as trade rates in Northern Ireland tend to be. More indoor units, heavy build-up on the fan or a blocked drain line are what move the price towards the upper figure. Typical Two units work (deep clean of two indoor units on one visit) lands around £245–£395 in this area.

Permissions
Cleaning the indoor unit is not refrigerant work. Anything the engineer finds beyond the clean, such as a leak or a failing fan, is explained and priced before it is touched.
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. Visits in County Down 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.
