HVAC Warning Signs

When your HVAC system is working properly, it should be relatively quiet. When your HVAC system starts making noises, it may be time to call in a professional.

Squealing or screeching coming from your HVAC system is one sign that it may need repairing. A squealing noise may indicate a bad belt or motor bearing problems. Belts are an inexpensive fix but need replacing at the first sign of trouble. The blower will no longer turn if the belt break. Lubricant will usually fix a noisy motor. Make sure you use the right oil when lubricating.

Other sounds to look out for are loud rattling, thumping, clanking or banging. Sounds like these typically indicate a problem with the blower assembly or motor. In most cases, rattling means that a component in the system is loose. A loose component needs to be fixed before the piece is completely disconnected or broken.

If you hear loud banging noises as the blower is running, turn off the system immediately. A loud banging noise means that something is already broken or disconnected.

A fast “thwapping” sound when the blower is running means that there is something stuck in the fan blades. If nothing is trapped in the blower blades, the “thwapping” sound could also indicate that something inside the housing is contacting the fan while it turns.

A clicking sound is normal to hear when the system is turned on and off. However, repeated clicking sounds are a sign of trouble. A faulty relay could cause clicking sounds from the control panel or outside compressor. An electrical control could also cause the repeated clicking sounds.

One more sound to look out for is rattling from the outside compressor and fan unit. Rattling should not occur when the fan in the compressor unit turns on. Rattling sounds from the outside compressor usually mean that there is loose hardware or a failing motor.

Excessive sounds from your HVAC Brooklyn system are never a good sign. Whenever you hear weird sounds, you should contact heating repair Staten Island. A professional heating Staten Island repair company will be able to locate the source. They will then be able to correct the issue before it becomes more severe.
