4 Issues You May Encounter With Your Furnace


If the furnace in your home is working efficiently, it should keep the temperatures at a comfortable level. That said, while your furnace is supposed to operate efficiently for a long time, it may sometimes run inefficiently or stop working altogether. Depending on the issue, you may need simple repairs or a component replacement with the help of an HVAC repair service contractor. Check out the common problems to watch out for in this guide.

Your Furnace Is Operating Loudly

You should call a heating contractor for inspection and repairs when you hear out-of-the-ordinary noises coming from your furnace. Note that your blower wheel is probably problematic if you notice scraping sounds from your unit. For example, the wheel can make such a noise if it's loose or broken. However, when you hear a screeching or squealing noise, you likely have an issue with the blower motor, or the belt may be broken.

Your Furnace Has Ignition Issues

If you're using an old furnace and you notice that the pilot light doesn't stay lit, contact your heating expert to investigate the cause of the problem. Different things may cause this problem, including a malfunctioning safety switch or the flame sensor isn't set correctly. Before you reignite the flame, disconnect the main gas valve for a few minutes. If your furnace uses electric igniters, your furnace repair technician will clean them and even replace them if they malfunction. 

Your Furnace Doesn't Turn On Automatically

As soon as the furnace receives the signal from the thermostat, it should turn on automatically. If this isn't the case, the problem could be minor or require extensive repairs. For instance, your furnace may fail to switch "on" if the circuit breaker has tripped. This may also happen if the thermostat isn't turned to the heat option or is malfunctioning. Other common causes of this issue include a clogged air filter or faulty pilot light.

A Crack On the Heat Exchanger

When your furnace heat exchanger has a crack, it will hamper your unit's ability to perform its role. That said, it can be challenging to tell if you have a cracked heat exchanger, but there are signs you should watch out for. One of the warning indicators is an unpleasant smell similar to formaldehyde. You may also notice soot buildup in the furnace's burners, and the pilot light will change to yellow.

If you notice any of the furnace issues mentioned above, contact a furnace repair professional to repair them as soon as possible. If you don't do this on time, you may have to replace the furnace, which is very costly.
