How to maintain your HVAC system.

Keeping cool on a hot sunny day or staying comfortably warm on a crisp winter night requires your HVAC system to be in good working order all year. These videos show you how much clearance is necessary around the condenser, how often the filter should be replaced, the best temperature for cost savings, how to clean the condensate line and more.

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.

Extend the Life of Your Heating and Cooling System, Part 2

Here are 3 more tips to keep your HVAC system running efficiently.

  • Know the best temp for cost savings—78 degrees in the summer 68 degrees in the winter.

  • Clean the condensate drain line. Pour a solution of 1 cup bleach and 3 cups water down the drain tube every three months.

  • Schedule a professional check-up. Schedule in the spring and fall to look for motor or electrical failures. Call the experts at Sears to check, fix or replace your HVAC. Schedule your HVAC preventative maintenance check today.
