  • Hissing

Many homeowners mistake this type of sound for the whooshing of air due to a lack of attention. According to the heating repair experts in San Luis Obispo, CA, this could be the sound of a gas leak in a furnace. Also, it may happen to a heat pump due to the leakage in the refrigerant line.

In any situation, turn off the system immediately and call for heating repair support as early as possible.

  • Screeching

Screeching is a sound that happens when the machine finds it hard to run efficiently. It can happen due to the blower motor in the furnace. A malfunctioned motor denotes that the system will not be able to produce enough heat for your home.

Lack of lubrication might lead to this situation. If such a problem continues for a long time, heating system replacement in San Luis Obispo, CA, is your best option.

  • Rattling

You might be familiar with this sound since rattling is common in machines. According to the HVAC experts, rattling sounds happen due to the following reasons:

  • It can result from a loose screw or panel inside the furnace.
