Are you hearing a strange sound coming from your HVAC system? The noise could be a sign that you have an issue with your unit. It is normal to hear an occasional click, but other noises can be a cause for concern. When you hear certain sounds, it’s time to call a professional HVAC company for a visit. Here are some sounds you definitely do not want to hear.
1. Banging Or Clanking
If you are hearing loud banging noises, there is a problem with the motor. When something is loose in the unit, you will start to hear a rattling sound. Broken components will make heavy bangs. In any case, you need to call a professional company for a full-service inspection.
2. Screeching
A bad belt can cause screeching that may be intermittent but severe. While this is annoying, you can easily fix the problem. Replacing the belt with a new one will usually take care of the issue. Once the belt snaps, your motor will no longer work. Some screeching noises are caused by unlubricated parts. By adding a little oil to the motor, you can resolve those noises.
3. Unusual Clicking Sounds
When the HVAC unit turns on and off, it is normal to hear a clicking sound. If you are hearing rapid clicking noises, that is not a good sign. This means the compressor or relay is bad and needs to be replaced.
4. Rattling
A well-maintained compressor should not make rattling sounds. If your compressor is rattling, your motor may be on the way out. These loud sounds indicate that you have a failing part. If you hear any rattling noises, your unit needs to be inspected by a trained technician.
5. Thwapping
If you are experiencing this sound, the blower blades are hitting a foreign object in your vents. As soon as you hear it, you need to remove any obstruction from your cooling system.
