In general, most HVAC systems will last 15 to 25 years, but depending on the type of system and other contributing factors, that estimate can be highly variable.

Heating and air conditioning equipment, no matter what kind you have, should be inspected, cleaned, and serviced at least once a year.

Take these steps to increase the efficiency of your heating and cooling system:

• Tune up your HVAC equipment yearly.
• Install a smart thermostat.
• Seal your heating and cooling ducts.
• Consider installing ENERGY STAR-certified heating and cooling equipment.
