If you’ve noticed your heat pump is louder than it used to be, it’s not just an annoyance—it’s a sign that something is wrong. At Moran Heat Pump Cleaning, we help Penobscot County homeowners identify and fix noisy units.

Common Causes of Noise

The most common cause of a noisy indoor unit is a dirty blower wheel. When dirt builds up unevenly, the wheel becomes unbalanced, leading to a vibrating or humming sound. In the outdoor unit, rattling is often caused by loose panels or debris like sticks and leaves trapped in the fan.

When to Call a Professional

If you hear grinding, squealing, or loud banging, shut the unit off immediately. These sounds often indicate mechanical failure. However, most humming and vibrating can be solved with a professional deep cleaning from Moran Heat Pump Cleaning.
