Telltale Signs That Your Furnace is in Need of a Repair


The furnace is responsible for heating your home and making sure that it reaches a comfortable temperature for your family. The furnace circulates air throughout the house, brings cold air in from the outside, heats this air, and sends it to your vents.

Because a furnace is an integral part of your home, it is essential to stay on top of its monitoring and maintenance. It is not indestructible. Your furnace can need repair over the course of its lifetime, and these are some of the signs that you need professional help.

Here’s what you need to know:

Abnormal Smells From the Furnace

When you turn on the furnace, the air inside is circulating and takes the warm air from your vents and distributes it evenly throughout the house. But if you notice a strange smell coming from the vents, there could be an issue. You could have an accumulation of dust or debris, there may be a leak or a dirty filter causing the problem, or there could be a more significant problem such as a broken motor.

Gas Leaks

A gas leak from your furnace is dangerous, especially if it is a propane furnace. You can tell if there is a gas leak by smelling your vents. If you smell gas or notice a pink or smoky residue on your vents, it could be the warning sign of a serious malfunction. You should never ignore a gas leak; if you smell gas or see residue, shut off your furnace immediately and call a professional.

Excessive Noise

If you hear strange noises coming from your furnace, it could be a warning sign of something wrong. This might be a rocker switch or relay that needs to be replaced. Be alert to any strange noises coming from your furnace and call a professional immediately.

The Furnace is Not Heating Up

A furnace that is not heating your home to the desired temperature could signify a serious problem. If you notice that you are cold in your home and it is not the temperature outside, there could be a problem with your furnace. It is essential to keep your furnace regularly serviced to know if there is a problem.

If you are experiencing any of these issues with your furnace, you must call a professional to give it a check.

Trouble Starting the Unit

If you start your furnace and it is taking a long time to turn on, it could be an issue with your thermostat. This can be an easy fix that you can do yourself with some troubleshooting steps. If the furnace starts to turn on but then shuts off after a few seconds, you have an issue that could be a problem with your motor, relay, or transformer. If the unit does not start, you need to call a professional immediately.

Rough Running and Abrupt Shut-Off

When your furnace starts and then shuts off, there may be an issue with your blower motor. If the fan seems to run too loud, it could be a sign of a problem. You might also notice that your blower seems to be running too fast. If so, you might need to get a cleaning and inspection of your furnace to see if you have a problem with a blower or motor.

The Bottom Line

The furnace is an integral part of your home, and you need to make sure that it is working correctly at all times. While it is true that sometimes things just happen and the unexpected can occur, most of the time, it is a sign of a larger problem that could have been avoided if you had taken the time to have your unit serviced.
