When it comes to keeping your family warm and your energy costs affordable, waiting until your heater breaks down to call for service is one of the worst things you can do. A unit that runs inefficiently consumes much more electricity or gas. When a heater runs without worn-out or broken parts, it puts immense strain on the entire system. This guide covers the three most important early warning signs to watch for to know when to schedule service.
1. The Furnace Makes a Loud Booming Noise Every Time It Kicks On
It’s completely normal to hear a smooth whooshing sound when the furnace kicks on; this is just the sound of the burners igniting. When you hear a loud booming or banging noise, you should be concerned. This means there’s gas building up in the combustion chamber. When the furnace cycles on, the accumulated gas ignites all at once, creating a booming noise that resembles a small explosion or a muffled bang. The system most likely has a dirty burner or delayed ignition issue that needs attention. You don’t want to keep using the heater when it has this problem because it puts major stress on the heat exchanger, which can lead to an even more costly repair.
2. You Hear a Loose Component Rattling Around
If the furnace kicks on and you hear a rattling sound, there’s likely a loose mounting screw, access panel, or blower wheel. It’s actually quite common for screws or fasteners to come loose over several years from the regular vibration that occurs during normal operation. A technician may need to do nothing more than tighten the loose hardware to fix the problem, or it could require replacing a worn or damaged component.
3. The Rooms Farthest From the Furnace Have Weak or No Airflow
When the rooms farthest from the furnace seem to stay much cooler than the rest of the home, you may have a clogged air filter. If you change the filter and it doesn’t resolve the issue, you’ll need to call for service. There’s a good chance one or more sections of the ductwork have loose connections, holes, or tears. This allows the warm air to escape before it reaches the rooms located farthest from the furnace, leaving those areas with the weakest airflow.
If your home experiences any of the warning signs mentioned above, you should schedule an appointment as soon as possible. Getting these problems fixed is crucial to saving money on your monthly heating costs and keeping your family warm during cooler weather. A trained technician will use advanced diagnostic tools to quickly spot the failure and choose the best repair method.
