Why Install an ENERGY STAR HVAC System?

Heating and cooling your home account for more than half of your home’s energy use and consequently, utility costs. We’re not making this up—take a look at how the Department of Energy breaks it down:

  • At 45 percent, heating accounts for the biggest portion of your home’s energy bills
  • Next up is water heating, at 18 percent
  • Following that is cooling at 9 percent
  • The rest breaks down into electronics, lighting, cooking, refrigeration, etc.

As you can see, one of the biggest opportunities for cutting down on your home’s energy use lies in your heating and cooling equipment. And, according to the Department of Energy, replacing your old HVAC system with ENERGY STAR qualified equipment can cut your annual energy bill by nearly $200.

ENERGY STAR Air Conditioners

GAC has been performing high quality AC installations in Gaithersburg since our doors opened in 1970. We take great pride in assessing your comfort needs and are an authorized dealer of the nation’s top manufacturers of high-efficiency air conditioning products.

In order to meet ENERGY STAR requirements in Maryland, central air conditioners must have a 14.5 SEER and 12 EER rating for split systems and a 14 SEER and 11 EER rating for single package system. Rest assured that GAC is armed with the best products, and our certified energy consultants can help you identify and select the most appropriate ENERGY STAR qualified cooling system for your home.


If you’re looking for an even more efficient heating and cooling system or if you want to save money on your heating and cooling bills, consider heat pump installation. According to the Department of Energy, if you currently heat with electricity, a heat pump can save you as much as 30 to 40 percent on your heating bills. Even more so if your heat pump meets ENERGY STAR requirements.

In order to gain an ENERGY STAR label, air source heat pumps must meet the following requirements:

Split systems:

  • 8.2 HSPF
  • 14.5 SEER
  • 12 EER

Singe package systems:

  • 8.0 HSPF
  • 14 SEER
  • 11 EER


With proper maintenance, most furnaces last 10-12 years. Whether you’ve had your furnace for more than 10 years and frequently require furnace repair or your furnace operates noisily or inefficiently, it might be time to consider a new furnace.

Whether you’re looking for a gas or propone furnace, we can help you find a system that meets ENERGY STAR requirements—allowing you to save money on your heating bills this winter.

In order to gain an ENERGY STAR label in Maryland (specifications are different in the U.S. South than they are in the U.S. North), furnaces must meet the following criteria:

Gas furnaces:

  • 90% AFUE
  • Less than or equal to 2.0% furnace fan efficiency
  • Less than or equal to 2.0% air leakage

Oil furnaces:

  • 85% AFUE
