Is Your Furnace Crying Out for Help in Louisville, KY?
A low hum should be the only noise you hear coming out of your furnace regularly. It’s fair to interpret most other noises as signals that something is not properly functioning. Here are some of the noises that your furnace might make and what they mean in Louisville, KY.
The most common explanation for your furnace producing whistling noises is that its filters are dirty and clogged. After enough debris accumulates on the filters, the air that passes through the filters will cause friction against that debris, creating a whistling sound. The solution here is to replace your filters routinely every two to three months.
Furnaces should produce clicking sounds when they start up, but this should only happen briefly. If the noise persists, you can be confident that something is preventing your furnace from starting and generating heat normally.
The following are possible contributors to clicking noises: dirty or broken burners, faulty flame sensors, a malfunctioning compressor, a bad control board and clogged ignition valves. These are the kinds of concerns that professional technicians address during furnace repair and maintenance appointments.
In some situations, popping noises are completely normal. If you hear popping sounds after you’ve started up your furnace following a period of inactivity, this is probably nothing to worry about.
It likely just means that your ductwork is slightly expanding and contracting in response to warm air flow. If the noise is exceptionally loud and continues for a long time, that could be a sign of trouble.
In that case, your furnace may have dirty or faulty burners. This could eventually cause your heat exchanger to crack if you do not have a professional address the issue.
