If you live in a cold climate, you most likely rely on your furnace around the clock during the coldest winter months to keep your home at a comfortable temperature. Since furnaces are used so often during cold weather, it is important to know the signs and symptoms of furnace problems so you can have your furnace repaired before it fails completely and leaves you and your family without a reliable source of heat. Some common signs of a problem with your furnace include:
Increase in Electric or Gas Bill
While gas and electricity rates do go up in price regularly, a marked increase in your utility bill may be a sign that your furnace needs to be serviced because it is not running efficiently. The higher gas or electric bills are typically a result of your furnace having to run much longer to produce ample heat to keep the house comfortable. This can be a common problem in furnaces that are older, or furnaces that do not receive regular service and maintenance.
If you are constantly adjusting your thermostat to find a comfortable temperature, or if some rooms are warm while others are cold, your furnace may no longer have the ability to properly distribute warm air properly. In addition to paying higher utility bills, ignoring the fact that your furnace is unevenly heating your home may lead to your furnace failing. It is a good idea to have a professional repair your furnace as soon as possible if you notice this problem.
Strange Noises from Your Furnace
When a furnace is running and is in good repair it should not make noticeable noises or sounds. If you turn your furnace on and hear squealing, popping, rattling, or banging sounds, that may be a sign that one or more components inside your furnace needs to be repaired or replaced in order for your furnace to function properly.
Constantly Running Air Blower
You may have a problem with your furnace if the air blower constantly turns on and off, even when the air temperature in your house is the same as the temperature on your thermostat. You will want to get your furnace checked out and repaired quickly if you are not able to stop the air blower by setting the thermostat in the OFF position, or if the air blower is blowing cool or cold air into your home.
