Ductless Air Conditioning Costs

Indoor Cost Guides      Air-Conditioning & Heating (HVAC)      Ductless Air Conditioning Costs

Ductless air conditioning is also known as split-system with its condenser unit mounted outside the building, and the evaporating unit mounted inside its climate zone with no ductwork. Refrigeration pipes pass into the building between condenser and evaporator.

You will find that the cost of ductless air-conditioning installation varies by type of unit, its cooling-capacity and efficiency rating, and the local labor rate.

In the following table the Labor Cost figure is what the able DIY person should expect to save by performing the corresponding tasks.

  • For a sunny room, add 10% more A/C capacity than required for room size.
  • Add 600 BTU/h’s per person if usually occupied by more than two persons.
  • For the kitchen, add 4,000 more BTU/h’s than required for room size.
  • During the initial inspection the contractor should inform the homeowner of any and all necessary modification or upgrade on electrical circuits or building structure.
