Prices in Larne
Our Northern Ireland guide price for a deep clean and odour treatment is £135–£225 per indoor unit, VAT included. Labour rates in Northern Ireland keep this slightly under the national middle. 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 Northern Ireland figures, the Two units option (deep clean of two indoor units on one visit) is about £245–£395.

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.
