When Is a Furnace Problem an Emergency?

While a complete loss of heat on a cold night is obviously an emergency, other situations threaten your safety even if your furnace is technically still running. For example, you need to treat any smell of sulfur or rotten eggs as an immediate danger, as this suggests a gas leak. You should evacuate your home or commercial building and call 9-1-1 or your gas company. We can address the underlying issue once it is safe to do so. Similarly, if your carbon monoxide detector goes off or if you hear loud booming noises upon ignition, you should shut your furnace down and request emergency service.

Signs Your Furnace Needs Repairs

Your furnace rarely breaks down without giving you a heads-up first. While it might be tempting to push those strange noises or weird smells to the back of your mind, ignoring these early red flags usually leads to much bigger headaches. Small mechanical hiccups can quickly spiral into major system failures, often right when a cold snap hits and you need heat the most. Catching these issues early helps save you money, delay the need for a replacement, and keep your property safe from hazards like carbon monoxide leaks.

Don’t wait to schedule a furnace inspection if you notice any of the following problems:

• Strange noises. Your furnace should run fairly quietly. Banging, screeching, rattling, or clicking sounds often point to loose components, motor failure, or ignition issues. If your unit sounds like it’s struggling, something inside likely needs tightening or replacing.
• Unusual smells. While a faint dust smell is normal when you first start your furnace in the fall, persistent odors point to trouble. A scent of burning plastic or rubber suggests an electrical fault or an overheating part. Musty odors indicate moisture or mold build-up, while the smell of rotten eggs signals a dangerous gas leak. Again, if you suspect a gas leak, evacuate your home or commercial building and call 9-1-1 or your gas company.
• Weak or cold airflow. When you feel weak airflow coming from the vents, or if the air feels lukewarm instead of hot, your blower fan or pilot light might be failing. This forces your system to work harder to reach the set temperature, driving up your energy bills without keeping you warm.
• Short cycling. A furnace that turns on and off frequently without ever reaching the desired temperature is "short cycling." This behavior puts immense stress on the heat exchanger and often indicates a clogged filter, a bad thermostat, or an oversized unit.
• Yellow pilot light. Your pilot light flame should always burn blue. A yellow or flickering flame indicates incomplete combustion, which can lead to a dangerous build-up of carbon monoxide. If you see this, we recommend turning off your furnace and contacting us immediately.
• Unexplained energy bill spikes. If your heating usage hasn't changed but your utility bill has skyrocketed, your furnace has likely lost efficiency. As parts wear down, your system will consume more energy to produce the same amount of heat. We can diagnose and address whichever component is draining your unit’s efficiency.
• Poor indoor air quality or dust build-up. An increase in dust around your home or respiratory issues among your family can signal a dirty system or a cracked heat exchanger that is circulating debris. We can inspect the internal components to determine if your furnace is compromising your indoor air quality.
• Thermostat issues. If you constantly have to adjust the dial to get comfortable, the problem might lie with the thermostat calibration or your furnace's ability to communicate with the controls.
