Furnace, Heat Pump, and Hybrid Heating System Maintenance Bethesda

Routine maintenance is the best way to keep your heating system running throughout the winter and prevent costly repairs. Heating systems are large, complex machines that run continuously in the coldest months, so they need professional care to stay in shape. Just as you maintain your car to keep it running smoothly, you should also take care of your heating and cooling equipment.

GAC Services offers heating maintenance and tune-ups in Bethesda to ensure the health and efficiency of your furnace, heat pump, or other heating system. In addition to being factory trained and NATE certified, our HVAC technicians are familiar with all makes and models of heating systems. They’ll perform a thorough check of your heating equipment and calibrate it for optimum performance. With regular maintenance from GAC Services, you’ll be able to rest easy knowing that your heating system will be there for you when you need it.

Your heating system should undergo a full tune-up once a year—generally in the fall before heating season begins. Contact GAC Services to schedule heating system maintenance in Bethesda today! You can also reach us at (240) 233-8498.

Benefits of Heating Maintenance

Winters in Bethesda are not to be taken lightly, so making sure that your heating system is up for the job is crucial to ensuring consistent heat through 20-degree nights. All heating systems wear down over time, but keeping your heating system maintained will:

  • Extend its life for additional years of warmth.
  • Prevent expensive breakdowns by catching small problems before they get worse.
  • Keep it running efficiently to save you money on energy.

Furnaces are powerful heating systems capable of producing a high level of heat immediately when you need it. Your gas, oil, or variable speed furnace needs maintenance to keep it running smoothly. When you call for a tune-up from GAC Services, our furnace specialists will inspect, test, and calibrate every part of your system. Your friendly HVAC technician will be sure to check the:

Heat Pump Maintenance in Bethesda

Heat pumps are innovative machines that transfer heat instead of creating it. They offer a slower, more steady heat and are extremely efficient. They also cool your home in the warmer months, meaning that they do double the job of a heater or air conditioner. Because it runs all year long to keep you comfortable, maintenance is crucial for your heat pump’s health and continued performance. During a heat pump maintenance check, our heating and cooling experts will:

  • Inspect ductwork
  • Inspect and replace or clean air filters
  • Inspect the blower
  • Inspect and clean indoor and outdoor coils
  • Lubricate motors
  • Tighten belts as needed
  • And more

Hybrid Heating System Maintenance in Bethesda

Hybrid heating systems are two-in-one machines that deliver the efficiency of a heat pump and the heating power of a furnace. They are more complex than either a heat pump or a furnace, meaning that maintenance is doubly important! Our highly trained technicians have the skill and experience to service these unique heating systems. They’ll perform a check on all components of your hybrid heating system and calibrate it for optimum performance. Your hybrid heating system is in good hands when you call GAC Services for heating maintenance!
