Your heating, ventilating, and air conditioning (HVAC, or Heating, Ventilating, and Air Conditioning) unit probably lives in an inhospitable location. Whether on the roof, side yard, or cellar, the unit probably lives with intense heat, cold, and grime.
Change air filters at least every 3 months, especially after summer and winter. You would work harder and harder to breathe if you wore the identical face mask for weeks or years. Same with your HVAC system!
Check the heating system before winter, and check the cooling system. Your regional building supply store may suggest a business or hire an air conditioning or heating contractor.

What Should an HVAC Service Include?
Watch your contractor support your unit. You might feel educated, understand their technical knowledge better, and believe that your money is well spent. Print out the Department of Energy’s HVAC maintenance checklist, and make sure that they do the following:
Check your thermostat–possibly, replace it with an ENERGY STAR device
Check connections, voltage, current, and wiring engines
Lubricate moving parts
Check your heating unit’s condensate drain
Check starting, operating, and shutoff controls for heating or cooling cycles
Clean the evaporator and a/c coils
Ensure the a/c refrigerant amount is right
Check airflow by cleaning and adjusting blower parts
Check connections, gas pressure, combustion, and heat exchanger to your heating unit
Your replacement device should have an ENERGY STAR system for potential tax credits and reduced operating expenses.
