HeatSmart Rebate Program

CMLP is now offering thousands of dollars in rebates to customers who install air-source or ground-source heat pumps in new or existing homes.

Heat pumps are highly efficient heating and cooling systems that can substantially reduce your carbon footprint. 

They can also provide long-term energy cost savings, especially if you currently have an oil, propane, or electric resistance heating system. 

Heat pumps can be installed in ducted or ductless forms for your whole house or for single rooms or zones that have unique heating or cooling needs.
