For County Antrim, expect roughly £135 to £225 per indoor unit, VAT included, adjusted for typical Northern Ireland rates. It is a touch below the UK middle, as trade rates in Northern Ireland tend to be. The price depends mainly on how many indoor units need cleaning and whether the fan and coil need a full strip-down.

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
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.
