Rebates & Programs


Boiler and Furnace Rebate Program

This program offers a rebate directly from ComfortSystems when you are looking for a new high efficiency boiler or furnace. When you buy a new high efficiency boiler or furnace from one of our trade partners and it is installed within the ComfortSystems service territory, you get a rebate from $50 to $200, depending on the efficiency of the unit. To qualify for the rebate, the unit installed must be on the ComfortSystems' rebate equipment list.

How do I get $200?
Here's the breakdown of the efficiency requirements for rebates:

  • Boiler at 83.5% and greater AFUE is eligible for $50 rebate
  • Boiler at 90% or greater AFUE is eligible for $200 rebate
  • Furnace at 90% and greater AFUE is eligible for a $200 rebate

Additional Rebates are available from Minnesota Power for ECM fan motors, ECM circulators, Central Air Conditioning or an Air Source Heat Pump.

Work with your dealer, contractor or installer to get the rebate. There is a form we need completed by the installer and signed by you. Once the furnace is installed, the paperwork is filed with us and the furnace is inspected by the City of Duluth, your rebate check will be issued.
