Troubleshooting 5 Common Furnace Problems

Just because your furnace seems to be having some trouble doesn’t mean you need to replace the entire unit just yet. Sometimes a simple change or fix can do the trick, and can save you the cost of a new furnace. Here are 5 things you should check if your furnace is no longer performing properly.

1. Make sure your furnace is getting power
   At some point you may have accidentally tripped a circuit breaker. Check the fuse box to make sure everything is as it should be. If your furnace seems to be tripping the circuit breaker fairly frequently it may be a sign of a larger electrical problem. Call an electrician and have he or she take a closer look.
2. Ensure the furnace is turned on
   This may seem fairly straightforward but since furnaces are often tucked away in small spaces you can easily bump the switch accidentally. Look for the power switch, which should be mounted on the side of the furnace. There may also be a liftable metal housing containing a fuse near the switch. If the fuse is black and burnt then it will need to be replaced. A burnt fuse may be a sign of a bigger problem so you should call in a licensed expert to assess the situation.
3. Check the fresh air intake port and the exhaust port
   Many newer furnaces run their fresh air intake ports and exhaust ports through the side of the home instead of chimneys. This means that moisture, leaves and insects can potentially cause problems with venting. If you notice that the ports seem to clog frequently speak to a licensed furnace technician about possible solutions.
4. Check your thermostat
   The problem may be with your thermostat, not your furnace. Check that your thermostat is set properly and that the batteries aren’t low.
5. Check the furnace filter
   If your furnace seems to be running normally but it isn’t blowing as hard as it does normally then you may have to change your air filter. Air filters trap dust, hair and other particles, filling up with debris over time. This can restrict airflow, and means that your furnace has to work harder to move warm air throughout the house. Most air filters need to be changed about every 3 months.

If your furnace is still not working properly you should call in a professional. He or she will have the knowledge to properly diagnose the problem and the tools and parts necessary to fix it.
