3 Heat Pump Noises You Can’t Ignore in Cleburne, TX

An efficient heat pump in your Cleburne, TX, home will produce soft humming sounds that are almost unnoticeable. Loud noises mostly suggest there’s an underlying problem with your system. Let’s explore some heat pump noises and what they mean.


A banging noise may occur when there are loose components in your heat pump. These components may hit each other when your system starts running. Also, the loose components may collide with fan blades, causing this noise.

If the loose components remain unattended for a long time, they can damage other parts, resulting in costly heat pump repairs. Therefore, schedule repair services immediately after you discover this noise.


If you don’t replace your air filter regularly, pollutants accumulate on it and prevent enough air from entering the heat pump. A whistling sound occurs as the system draws air through the tiny openings left on the filter.

A clogged air filter makes your heat pump work harder than usual. Replace your air filter after every month or two to allow enough air to pass through the filter.

You may also hear a whistling noise when air escapes through perforations in your ductwork. Ductwork leaks make your system overwork and cause uneven temperature distribution in the house.

A whistling sound can also occur due to refrigerant leaks. A compressor raises the temperature and pressure of this vital fluid to make it release heat. The whistling sound occurs when the high-pressure refrigerant escapes through tiny holes along the refrigerant lines.


You may hear rattling when the outdoor unit’s cover panel is loose. Tightening this panel should solve the problem. Other times, a rattling sound may be a sign of more severe issues, such as a faulty air handler or overly tight coolant piping.

The longer you wait, the worse heat pump noises get. Call Airmasters AC, Heat, Plumbing & Electrical for professional heat pump services whenever you detect unusual noises coming from your system. Our team will correctly diagnose the problem and repair it.
