Limited-time Increased Rebates: Save more money on select heating equipment today—and save energy for years to come.

Get exclusive limited-time increased rebates on high-efficiency gas heating equipment through August 31*

Even after the heating season ends, Summer is a good time to think about how new, high-efficiency heating and water-heating equipment can help you save energy. When winter is over and you’re using your equipment less, it’s a great time to upgrade—especially if you are selling or remodeling your home. That’s because new, high-efficiency equipment can increase the value and reduce natural gas use in the long term.

Don’t miss out. Check on the age and health of your current heating and water-hearing equipment to see if it is the right time for you to upgrade your water heater, furnace or boiler to a high-efficiency model.

Use this chart to see if you should upgrade your water heater, furnace or boiler to a high-efficiency model.
