A furnace is an essential piece of equipment in your home. However, it’s a complex piece of machinery that requires regular maintenance to ensure it continues functioning properly. Therefore, if your furnace starts behaving strangely or doesn’t work, it may be time to call WireNut Home Services. In this article, we’ll look at common signs that indicate your furnace needs servicing so you can get it back up and running as soon as possible.

Your Furnace Is Smoking

If your furnace is smoking, it might be time to inspect it. The smoke can be caused by several issues, including a bad motor or fan. It could also mean that the igniter needs replacement.

Your Furnace Is Making a Strange Noise

Your furnace may be making strange noises for several reasons. If you hear a clicking sound when the fan is on, this could be a sign that your capacitor needs to be replaced. If the fan makes a grinding noise, then it may be time to replace your motor brushes or contactor coils. If there’s an intermittent humming sound coming from your furnace, it could mean one of two things:

either you have loose wires or damage in an electrical component such as an overload protector, or there is dust buildup on the blower wheel bearings inside the unit itself. Suppose none of these sounds are familiar to you and continue after checking all other possibilities, such as adjusting your thermostat, it might be time to call in an expert. This does not necessarily mean anything is wrong with your system; it could simply need cleaning.

You Need to Call for Repairs Frequently

If you have to call for repairs frequently, it could be a sign that your furnace is on its last legs. Many factors affect how often a furnace needs repair, including the quality of service provided by the company that installed your system and whether adequate maintenance was done on it before use. If a problem arises with your current system, it may be relatively simple to fix or prove more costly than expected to repair.

You Have a High Gas or Electric Bill

The cost of heating your home is directly related to the energy you use, so if your bill is higher than usual, it could be a sign that something is wrong with your furnace. You might need to have a professional look at it.

The Furnace Is Not Blowing Any Air

If your furnace isn’t working or heating the house properly, this could be an issue with the blower motor and other components of your furnace. These systems are complex and require proper maintenance to continue working without issue. Therefore you must contact a qualified HVAC technician if you notice any issues with your heating and cooling system.


If you notice any of these signs, you should call for repair as soon as possible. Doing so will ensure that your furnace doesn’t break down entirely and put you in danger during the winter. If something is wrong with your furnace and it breaks down, it may be necessary to replace it with a new one. Replacing your furnace can be expensive because parts are needed, and ductwork needs replacing to ensure that air flows properly throughout the house. Sometimes your furnace needs some TLC from professionals who know what they’re doing.
