Air Conditioner/Heat Pump Rebate


If your cooling system is older than 10 years, you have frequent service problems and/or you see your utility bills going up, it is time to consider installing a new unit. Upgrading to a more efficient air conditioning unit can substantially reduce your cooling costs.

Our commercial rebates range from $570 to $3,010 depending on the size and the efficiency rating of the unit. (see residential efficiency rebate information for smaller systems) Both owners of commercial buildings and/or the tenants that lease the commercial spaces are eligible for our commercial rebate program. All commercial and industrial customer classifications are eligible. Due to the increased costs of higher efficiency units, the amount of the rebate offered to you goes up with a more efficient unit. Units that are sized for commercial use go by the Energy Efficiency Rating (EER) system.

DUCTWORK: A heating and cooling system ductwork inspection will be completed by Columbia Water & Light before the rebate is issued. We want to insure that all supply and return vents that are visually accessible are properly connected. It is commonly found that ductwork has been disconnected which creates obvious inefficiency problems.
