Why Is My Heat Pump So Loud in Charleston, SC?

Whirring and clicking are normal sounds when it comes to heat pumps. However, noises other than those two can indicate a problem at your home in Charleston, SC. Here are some common heat pump noises and what they mean.

Hissing

In most cases, hissing noises mean that there’s a coolant leak somewhere in the system. This causes a drop in pressure, which could lead to ice forming on different parts of your heat pump. This issue requires a professional technician to repair.

Rattling and Shaking

If your heat pump rattles or shakes, then one of the mechanical pieces inside is loose. The HVAC system vibrates naturally while running, and while the loose component is rattling, it can damage other parts inside the system. If the loose piece is in the blower, then it can unbalance the fan and cause other damage.

Shrieking

Most often, a high-pitched shriek or whine means there is a loose belt within the system. It could also mean that one of the moving parts inside the system has become misaligned and is contacting another surface.

Thumping

Like rattling, thumping indicates that something is loose in your heat pump. However, when your heat pump thumps, the loose part is much bigger than it is in the case where the system rattles. The chance for damage is greater with thumping, so it’s a good idea to have a professional technician examine your HVAC system immediately.
