Request ServiceWhy Is Your Furnace Whistling?
Monitoring your furnace is a key part of catching issues before they worsen. A noisy furnace is often attributed to problems with the filter or ductwork. However, some noises can indicate something has gone wrong with the gas supply valve. Here are the most common reasons behind a whistling furnace.
Clogged Filters
A dirty filter may cause a whistling sound if it’s impacting airflow into the system. The noise comes from the air being pulled through the clogged filter into the furnace. Dirty filters allow excessive dust and debris into the system, increasing wear and tear. It’s essential to switch out your filters regularly to protect your HVAC system’s air supply.
Leaking Ducts
Another common issue that causes whistling is leaky ductwork. As your ducts age and deteriorate, they’re more likely to develop tears and leaks. These air leaks can make noises as they waste your valuable heating. Routine maintenance is the best way to prevent leaks from developing and skyrocketing your energy bills. An experienced technician will also be able to tell you if your ductwork isn’t the right size to handle your furnace.
Compromised Gas Valve
Gas furnaces use valves to moderate the flow of fuel into the system. When this valve becomes compromised, it can let out gas in a high-pressure stream that causes a whistling sound. If your gas valve is damaged, you’ll often notice an additional unpleasant odor. This issue should be professionally repaired as soon as possible to protect your household and home.
