Frequently Asked Questions


Why is my furnace running but not heating?

Your system may be experiencing trouble with the ignition system or the fuel supply. Either the furnace isn’t receiving fuel or it isn’t igniting it to generate heat. Your gas valve may be closed, or you may have run out of propane in your tank. Older units may have a pilot light that has been extinguished and needs to be relit. In the case of units with an electronic ignition system, the switch may be dirty. This prevents the contact necessary to light the fuel.


What is the most common reason a furnace stops working?

Clogged filters are one of the most common causes of furnace issues. Making sure you clean or replace your filters once a month will ensure you don’t experience airflow problems that can cause your unit to stop working.


When should you repair or replace your furnace?

The surest sign of trouble with your heating system is a sudden and unexplained rise in your utility bills. If you’ve noticed the cost of using your furnace has increased significantly without your usage increasing, it may be time to have it checked. Most furnaces have a lifespan of about 10 to 15 years, so if yours is about that old you should probably think about replacing it. Even if it’s not that old, you should replace it if the cost to repair it turns out to be higher than buying and installing a new unit.
