Extend the life of your heating and cooling system

These tips will keep your HVAC system in top shape.

  • Clear out debris. Cut or remove plants that are within 1 foot of the condenser.

  • Replace the filter every few months. Any buildup reduces the amount of air the system draws in.

  • Check that your furnace flame is a crisp blue. If it's wavy, orange or yellow, call a technician.
