Air conditioning repair and maintenance

Taking care of your air conditioner is crucial if you want to keep it running effectively. Neglecting your air conditioner can result in it either breaking down more easily or running less efficiently, which causes your energy bills to go up. When it's time for air conditioner repair, replacement, or maintenance, call Great Northern Heating & Air.

Common Air Conditioner Problems 

  • The air conditioner won’t turn on
  • Weird noises or vibrating occur at startup or during operation
  • Warm air exits the supply registers
  • The unit hums, but the fan doesn’t turn on

Furnace repair and maintenance

Furnaces require routine maintenance in order to maximize performance, maintain efficiency, and ensure safety. Ensure safe, efficient operation and prevent unexpected issues before they occur by scheduling professional inspection and routine maintenance at least once per year before the heating season begins. Call Great Northern Heating & Air to schedule your inspection and maintenance this fall!
