How to Replace Your Old Heating System

Your choice of heating system affects your energy bill. If you need to replace an old or failing heating system, or are ready to upgrade, we recommend that you:

1. Find a Contractor.

A DCSEU participating Heating and Cooling contractor can help you and make sure your choices are eligible for rebates.

3. Get a Rebate.

DCSEU rebates help offset the increased cost of high-efficiency heating systems.

Get More Out of Your Energy Dollar

Simply purchasing new equipment doesn't give you the maximum savings from efficiency. Consider ENERGY STAR systems. The higher the AFUE the more efficient the system. See the difference in energy costs below (based on savings from natural gas boilers).

A graph illustrating that annual energy costs for newer ENERGY STAR systems is lower than older systems

Get Started
