GAC Heat Pump Solutions

Heat Pump Repair, Maintenance & Installation in Potomac, MD

As the cost of energy rises, GAC is more determined than ever to find ways to save you money on your energy bills. That’s why when it comes to cooling AND heating your home, we can’t say enough good things about the heat pump.

Heat pumps work by transferring heat—out of your home in the summer and into your home in the winter—rather than by converting energy into heat. For this reason, if you currently heat and cool with electricity, a heat pump could save you as much as 30 to 40 percent on your energy bills.

Why purchase, install, repair, and maintain two HVAC systems when you can have it all with one convenient, energy-efficient unit?

If you’re looking for heat pump services, contact GAC Services. Our factory-trained, award-winning technicians are here and ready to help!

Hybrid Heating Solutions in Potomac

While Potomac residents like yourself generally can expect a mild winter, Maryland can experience some extreme low temperatures during the winter months.

For extreme cold, we recommend combining the strengths of gas and electric heat sources with a hybrid heating system. This system comprises a gas furnace and heat pump. When the temperature changes, the system automatically switches to the most cost-effective fuel source for the present conditions.

FAQs of Furnace Care

Ensuring you keep to a robust furnace maintenance checklist is the best way to keep your home ready and equipped to take on winter and fall. Follow along and get answers about how to care for your furnace from our local heating contractors!

  • How often should you have your furnace serviced? Professional furnace maintenance is a crucial part of getting the most from your heating system and should be sought annually at a minimum—more frequent service calls may be needed if the system is 10 years old or older.
  • How much does it cost for furnace maintenance? Maintenance cost can range a bit depending on the type of heating system, its age, and whether or not furnace repairs or parts replacement will be included in the service. For the best prices and service, we recommend selecting an HVAC maintenance plan that suits your needs and heating budget.
  • How can I DIY furnace maintenance? Most of the tasks handled by a professional should be left to a professional, as they require precise care and costly, training-required tools. However, as a homeowner, it is smart to replace your air filter frequently to aid in effective heating and better airflow, which will reduce the risks of a breakdown.
  • How long does a gas furnace usually last? When properly cared for, a gas furnace should last 15 years, sometimes more. For an electric furnace, 10-13 years is about average. In order to last this long, it is imperative that annual service is a part of your furnace’s life!
  • How much does it cost to install a furnace? New furnace and AC costs tend to vary considerably depending upon the system you have selected, whether or not electrical and ductwork are involved, and a few other factors pertaining to labor. It’s always a good idea to take the time to shop around and find the contractor that is going to help you find the right heating system—not someone who’s just trying to make a furnace sale.
