Signs of Trouble With Your Furnace


When winter strikes, the last thing you need is a broken furnace. You can call a local technician for an emergency repair, but it’s always more cost-effective to schedule service before a total breakdown. 


Most HVAC systems give a few warning signs that they are about to leave you in the cold. Unfortunately, these signals often get overlooked. Do you know how to tell if your furnace is failing in Lafayette?


How to Tell if Your Furnace Is Failing in Lafayette 

If you notice any of these early warning signs, it’s time to call an experienced HVAC company and schedule an inspection


Unexplained Higher Heating Bills 

If you’ve noticed a steady climb in your energy bill without a rate increase or cold spell, your furnace could be starting to struggle. Check the air filter for any obstructions or excess dirt. Dirty air filters make your system work overtime to keep up with the thermostat setting. 


Strange Noises 

All heating systems make some noise when they operate. Eventually, these sounds become familiar to you. If you notice new noises, though, like a pop or squeak, your system needs attention. 


The change could indicate that a loose screw or other component requires tightening. But it could also be something more significant that needs repairing before it becomes a bigger problem. 


Discolored Pilot Light

Gas furnaces have a bright blue flame called the pilot light. If you notice yours glowing yellow, you may have a carbon monoxide problem. A yellow pilot light often signifies that the gas does not have the correct ventilation. Any carbon monoxide issue is serious, and you must address it immediately. 


Poor Air Quality 

Your furnace directly impacts the indoor air quality. A poorly maintained system forces bacteria, dirt, and other debris throughout your home when it blows heated air. You may notice an increase in dust accumulating on shelves or furniture. Some family members may experience frequent coughs, colds, or other respiratory problems. 


Sometimes, you can resolve this problem by changing the air filter. However, in other cases, the only solution is to repair the ductwork or schedule a professional duct cleaning.
