We provide Air Conditioning Energy Inspections in line with the methodology set out in CIBSE TM44:2012 direct to businesses, landlords, building owners and tenants. A building requires an air conditioning inspection if it has 12kW or more of cooling installed. So if your property has three split systems of 3.5kW and one of 2.5kW, the total cooling is 13.0kW then this building would require an air condtioning inspection to be conducted every five years. A cooling system only needs to be inspected if it is over five years old.
