What to Do With a Noisy HVAC Unit

A noisy HVAC unit usually means trouble. When your unit works overtime it can age quickly. Different noises coming from your unit can mean different things, but whenever you hear an unusual sound coming from your HVAC unit make sure to call a professional to inspect it.

Common Noises

Noisy units can be caused by dirty coils, clogged air filters, leaks, faulty controls, and more.

A common issue with HVAC units are malfunctions of the blower. This is a sign that the fan motors need to be replaced. If you hear rattles and squeals coming from your unit after start-up you should call an HVAC technician to come out and fix any malfunctions.

Buzzing and humming noises are also very common and are usually caused by loose parts, debris in the unit, a loose fan motor, leaks, a dirty condenser coil, or a dirty air filter.

Other Noises to Be Aware of 

It isn’t uncommon for units to make some noise while starting up or shutting down, but if certain noises persist then it might be time for a repair.

Clicks, clanks, and bangs usually mean there is a loose part like a loose fan blade or that the compressor should be replaced.

A clogged filter, leaky duct, or other issues with the fan motor speed of your unit will cause whistles. Luckily, this isn’t an emergency issue but can affect how your unit runs.
