HVAC Program

Save on energy costs with high-efficiency, ENERGY STAR® certified HVAC equipment for your home.

Did you know that nearly half of your home’s energy bill is heating, ventilation, and cooling costs?* Installing high-efficiency HVAC equipment can help lower your energy costs and make your home more comfortable.

Available Discounts

  • ENERGY STAR certified geothermal heat pumps are over 45% more energy efficient than standard options and are among the most efficient and comfortable heating and cooling technologies currently available.* Learn about rebates offered by the Maryland Energy Administration for geothermal systems.

  • Cold climate heat pumps are specifically designed to operate at low outdoor air temperatures and excel at providing space heating even in the coldest of climates.*

  • If your central air conditioning unit is more than 12 years old, replacing it with an ENERGY STAR® certified model could cut your cooling costs by 30%*

  • ENERGY STAR certified heat pumps use about 5% less energy to heat and cool your home than conventional models.* Use this fact sheet to find out if an ENERGY STAR certified air source heat pump is right for you.

  • ENERGY STAR certified ductless mini split systems can cut cooling costs by 30% compared to conventional room air conditioners. This alternative to window, baseboard or portable units, delivers warm or cool air directly into zoned areas of your home. Because it requires no ducts, it avoids the energy loss common with ductwork in central forced air systems. Use this fact sheet to find out if an ENERGY STAR certified ductless mini split is right for you.

  • PTHPs are similar to a high-quality version of the window-mounted air conditioner with heat pump accessories added. ENERGY STAR certified models dehumidify better than standard central air conditioners, resulting in less energy usage and more cooling comfort in summer months.*

  • An ENERGY STAR certified smart thermostat delivers significant savings on heating and cooling costs because you can monitor and adjust temperatures even when you’re away.* Use this fact sheet to find out if an ENERGY STAR certified smart thermostat is right for you.

  • PTACs are air conditioning units installed through a wall. They are built to heat and cool spaces quickly and are often quieter and more efficient than other models.*

  • ENERGY STAR certified bathroom fans use about 50% less energy than standard models to provide better efficiency and comfort with less noise.*

  • ENERGY STAR certified circulating pumps allow your heating and air conditioning system to perform with increased efficiency while significantly reducing the system’s electrical usage.*
