7 Furnace Warning Signs You Shouldn’t Ignore

Furnaces can only last so long. Over time, the parts will wear out, your system will lose efficiency, and eventually, your furnace will experience a total system shutdown. This can be very inconvenient, especially if it is during one of the coldest days of winter in Montgomery County.

Luckily, there are multiple warning signs that can signify your furnace will completely fail soon. If you pay attention to these signs, Worcester HVAC can help you choose and install a new furnace before it’s too late. This way your family can be warm and comfortable all winter long.

Lack of Comfort

The main purpose of your HVAC system is to provide you and your family with comfort. Therefore, if your Montgomery home is uncomfortable, your HVAC system is not doing its job. There are many reasons why your home may lack comfort, but a failing furnace is certainly one of them. If your home is uncomfortable and you notice some of the other items on this list, it is a good sign that your system is failing.

Many Repairs and Age

Some signs are fairly obvious. If your system is 15-20 years old and has been needing many repairs recently, you should start talking to Worcester HVAC about a replacement. You may also be able to see visual damage. Over time your system will experience a lot of wear and tear. Wear and tear can be seen and is what leads to a need for repairs.

Repairs can get expensive if you need many of them. Eventually, you get to a point where a new system would be cheaper than all of the necessary repairs. When your furnace reaches this point, it is time to replace it.


Similar to visual wear and tear, strange noises can also signify major issues. Some noises that signify issues include banging, whistling, clanking, popping, rattling, and grinding. You can also pay attention to the sound of your furnace starting up and turning off. If this process seems to be occurring more frequently, you should have Worcester HVAC inspect your system.

High Utility Bills

Your HVAC system uses the most energy when it starts up. Therefore, if your system is starting up more frequently, you will also notice a rise in your utility bills. High utility bills can signify that your furnace is struggling to warm your home, which may mean it’s nearing its end.

When it comes to HVAC system’s the more efficient your system is, the more energy you will save, and the less money you will spend. This is why it is important to take proper care of your system. Change the filter regularly and contact Worcester HVAC twice per year for preventative maintenance. Doing so will help keep your utility bills low.

Your Home is Extra Dusty

If your furnace is getting old and nearing the end, it likely won’t be able to clean the air as well anymore. This means you will likely notice more dust and dirt around your Worcester home. You may also find your family sneezing or coughing more often.

However, this issue can also be caused by something more simple such as a dirty filter or air ducts. Change your filter. If the problem does not resolve, contact Worcester HVAC for more help.

Your Family Hasn’t Been Feeling Well

One of the most dangerous threats is a carbon monoxide leak. Carbon monoxide is a colorless and odorless gas that can kill you. It is difficult to detect on your own. One of the best ways to protect yourself is to get a carbon monoxide detector.

Also, pay attention to how your family is feeling. If everyone is having flu-like symptoms such as headaches, burning eyes or nose, nausea, or dizziness, evacuate your home immediately, call 911 or go directly to the hospital.

If your detector goes off, but you are not experiencing symptoms, open the windows, turn off any gas appliances, and evacuate your home. Call the local gas company for assistance. Once your home has been cleared call a professional technician to help you repair the issue.

Yellow Pilot Light

When the pilot light in your furnace is yellow, it means that the gas is not being lit completely. There are a few different reasons this can occur. One of the most common is dirt in the burner. However, it can also signify carbon monoxide or a failing furnace. If you need help with a yellow pilot light, contact the professionals at Worcester HVAC. You can do so through our website or by calling 610-287-HEAT.
