Regularly change your furnace filter. It's the #1 way to prolong the life of your system.

No matter what type of heating and cooling system you have, it should be serviced every year by a certified technician.

For gas and oil furnaces, your service technician should:

• Clean the burner and heat exchanger, if necessary, as well as any other component in need of cleaning.
• Inspect the venting system and verify that it is operating properly.
• Check for rust, soot, leaks, corroded electrical contacts and frayed wires.

For cooling systems, your servicer should:

• Clean the indoor evaporator coil if necessary.
• Check the refrigerant level.
• Make sure the compressor and outdoor fan motor are operating properly.
• Inspect all electrical connections.
• Clean the furnace or air handler blower assembly and check for proper operation.

If the refrigerant level is low in your air conditioner or heat pump, your technician should
perform a proper leak check and then either replace the leaking component or repair the leak.
