5 Signs Your Heater Is Struggling


The holiday season brings many merry and joyful things we’ve come to count on. Some of these include spending time with friends and family, enjoying delicious holiday treats, and having a warm and toasty home. 

Perhaps you’re not so certain that you’ll be able to depend on your furnace when you need it during the holiday season and into the New Year. If you suspect your furnace might leave you in the cold this winter, you need to know the warning signs that indicate you may need furnace repairs.

It’s better to schedule service at the first signs of trouble rather than wait. Getting repairs done early on will not only save money, but it’ll keep you and your family safe. Read on to learn 5 signs you need furnace repairs and why it’s so important to be able to recognize them.

#1 High Energy Bills

Take a few minutes out of your busy holiday schedule to evaluate your energy bills. Have they gone up without any correlation in usage? Increased energy bills indicate there’s a problem with your heater that is hindering its operation. Instead of paying more money to the utility company, put that money to better use by addressing the issues that are causing poor system performance and getting the necessary repairs done.

#2 Weak Airflow

This problem occurs when warm air isn’t reaching all the rooms of your home. You might also notice that the warm air that should be flowing from your vents is weak and not as warm as it should be. Eliminate weak airflow and cold pockets throughout your house by getting your heater checked out.

#3 Strange Smells

Nobody wants to detect smells like musty socks, mold, rotten eggs, or burning metal during the holiday season! But a malfunctioning heater will produce yucky smells like these that are a cause for concern. If your heater is interfering with the smell of holiday cookies, don’t put up with it any longer. Schedule service to determine what’s interfering with your holiday joy.

#4 Strange Sounds

The only noises a heater should make are when it turns on and off and the sound of air flowing through the vents. Unusual noises such as squealing, screeching, hissing, and popping are signs that something is wrong. A noisy furnace could quickly become a safety hazard so it’s imperative to have strange sounds checked out as soon as possible.

#5 Yellow Pilot Light

The pilot light in your furnace should be a steady blue. A yellow or orange pilot light could signal a potentially hazardous problem such as a carbon monoxide leak or a cracked heat exchanger. If you notice your pilot light is any color other than blue, call us immediately to schedule service.

Do any of these sound familiar? If so, reach out to our team for professional heater repairs, and rest assured that your system will get the service it needs to see you through the winter.
