If you’re reading this, we’re guessing your furnace doesn’t sound like a light breeze or hum when it runs. Furnaces generally don’t bang, clang, or rattle without having something wrong in the system or unit. This begs the question: Why is my furnace so loud?
As an industry leader in HVAC in Buena Park, CA, Airmerica Air Conditioning & Heating Inc. may have the answer. A noisy furnace may have several causes, but it also has several solutions. If you have no HVAC experience, rely on our experts to fix noisy furnace problems quickly and efficiently.
Three Common Furnace Issues That Make Buena Park Households Noisy
Since so many different conditions can cause furnace sounds, we’ll mainly focus on three of them here. You may be able to resolve these on your own if you have the right tools and experience with your HVAC system.
1. Clogged Air Filters
The occasionally muggy conditions in Buena Park can lead to more pollen, dust, and other airborne debris floating around. While your air filters protect your furnace from clogging up, you need to replace them regularly.
The more you use your furnace, the more often you should replace your air filters. At the very least, replace them every 90 days. Otherwise, air will have trouble traveling through the HVAC system.
Loud whistling combined with poor room heating could mean you have a clogged filter. In this case, the sound comes from the air forcing its way through the filter, pushing through the gunk.
2. Blocked Vents
Sometimes, the noise can come from objects blocking the vents, such as dust, grime, or furniture. For example, homes with floor vents can collect animal hair or have a curtain or seat blocking the airflow.
A blockage can also develop inside the vent rather than outside. Moisture combined with usual dust or dirt from daily living can collect and clog the vent system. Just like if you have clogged filters, the air blowing through tight spaces can cause whistling.
3. Ductwork Trouble
Why is my furnace so loud and making banging or popping noises when I turn it on? Sometimes, the problem may not be your furnace but the ductwork transporting the air.
When air conditions change from warm to cold or vice versa, they can cause reactions in surrounding materials. Heat often causes expansion, while the cold often causes contraction. Metals behave no differently, with your ductwork expanding and contracting with temperature differences.
So, sometimes, the crackle or pop is normal and you can rest assured your system is fine. However, it shouldn’t be so loud or constant that it disturbs you or others. Disruptive popping or rattling noises may indicate loose parts in your ducts or that a part of the system isn’t connected properly.
Why Address Noisy Furnaces in Buena Park?
A furnace making noise sometimes is not unusual. As a mechanical device, it has various internal components that can make different sounds.
This doesn’t mean that it doesn’t require maintenance. If you don’t maintain your system, its furnace efficiency rating will become irrelevant since the equipment will become less efficient over time. It will fail to work properly and potentially cause various health and wellness-related issues.
Ask an expert, “Why is my furnace so loud?” and they’ll tell you that it’s operating above its usual noise levels because some component not working as it should. You can think of the noise as an unofficial alarm system for your furnace and related HVAC equipment.
Cold weather in Buena Park can quickly become uncomfortable without proper heating. To ensure your furnace works anytime you need it, act promptly when it starts making unusually loud or disruptive noises.
