These are the questions that our customers usually ask about heating.
How often do I need to service my furnace?
It all depends on the environment your furnace is running in. If your furnace or boiler is running in an environment that has a lot of dust or animal hair‚ then it might be worth it to have your furnace checked once a year. If your furnace is running in a relatively clean environment‚ you can probably get away with 2 or 3 years.
How often do I need to change my furnace filter?
A dirty air filter can cause big problems on a furnace heating exchanger and furnace blower motor. A heat exchanger is like your car engine if you don’t have enough air (antifreeze) removing heat off the surface it runs too hot in the winter. If you have air conditioning a dirty filter can cause the “A” coil that circulates freon located on top of the furnace to freeze in the summer. A dirty air filter can also cause the furnace blower motor to pull more electricity and over heat as well. My advice would be to change the furnace filter at least once every 4 to 6 weeks during heating season and for air conditioning once a month.
Why is the furnace blower motor running but no heat is coming out?
1.) The igniter (no more pilot takes the place of the pilot on newer furnaces) is bad and needs to replaced. 2.) You have a dirty filter and the high temperature limit tripped the furnace to run the fan constantly without heat to cool the furnace. If the fan doses not shut down and allow the heat to start the limit may need to be reset. 3.) The thermostat in the home maybe in the fan/on mode.
