Furnaces are an efficient way to stave off the cold winter nights in Mansfield, TX. A typical furnace has a lifespan of about 20 years. Around this time, you might start to notice unusual sounds when it performs a heating cycle. If you hear any of these four sounds coming from your heating system, it’s important to have a trained service technician take a look at it:
An off-balance motor or blower wheel could cause a thumping sound during heating cycles. If you don’t correct this problem, it could cause the motor to overheat. A blown motor will stop your heating system from completing heating cycles.
There are several possible causes of squealing sounds coming from your furnace. A belt may have come loose, or it may be thread-bare. One of the shaft bearings may have lost lubrication or slipped out of place. The blower’s motor could be malfunctioning. All of these issues require professional attention.
If you hear a sound similar to fingernails on a chalkboard, your heating system is on the fritz. This sound usually results from metal scraping against metal. The blower motor may have loose or damaged parts, or it could be off-balance.
If you hear a loud humming sound when your furnace starts, this could be due to an electrical problem. The blower motor draws a lot of electricity to start working. This initial large draw of power could be stressing your home’s wiring. The capacitor or fan could also be failing.
A malfunctioning furnace in your Mansfield, TX, home can be a serious health and safety risk. By listening for these unusual sounds, you’ll know to arrange for a service visit as soon as possible.
