6 Furnace Noises You Shouldn't Ignore

When it comes to furnace repair, it's important to know the sounds that your furnace shouldn't be making. These sounds can indicate a serious problem with your heating system, and it's best to call a professional HVAC company such as Zion Custom Air to diagnose and fix the issue. Here are six sounds that your furnace shouldn't be making.

Scraping or Grinding Sounds

These sounds can indicate that a component of your furnace, such as a blower fan, is loose or damaged. If left unrepaired, it can cause further damage to your furnace and potentially lead to a breakdown.

Popping or Crackling Sounds

These sounds are often caused by dirt or debris in your furnace's burners. They can also indicate a problem with the ignition system. A professional HVAC technician can clean the burners and check the ignition system to resolve this issue.

Humming Sounds

A humming sound can indicate a problem with your furnace's blower motor. The motor may be failing or overworked, which can cause the furnace to stop working altogether. It's important to have a professional HVAC technician check the motor to ensure it's running properly.

Banging or Thumping Sounds

These sounds can indicate that your furnace's ductwork is loose or damaged. If you feel a threat to your furnace and cannot handle the situation on your own, call Zion Custom Air to check the ductwork to ensure it's properly sealed and insulated.

Squealing or Whining Sounds

These sounds can indicate that a belt on your furnace's blower fan is loose or damaged. Have a professional HVAC company replace or adjust the belt to resolve this issue.

Rumbling Sounds

This sound can indicate that your furnace's burners are dirty or clogged. A professional HVAC technician can clean and service the burners to resolve this issue.

It's important to note that some of these sounds may be caused by something other than your furnace. For example, popping or crackling sounds could be caused by the work, and banging or thumping sounds could be caused by the AC repair. Therefore, it is important to have a professional HVAC company to diagnose and fix the issue.

Leave it to the Experts

It's also important to note that furnace repair can be dangerous. Furnace repair involves working with gas and electricity, which can be dangerous if you're not trained to do so. Therefore, it's best to leave furnace repair to the professionals. They have the knowledge and experience to safely diagnose and fix the problem.

It's important to be aware of the sounds your furnace shouldn't be making. If you hear any of the sounds listed above, it's best to call a professional AC repair company to diagnose and fix the issue. Not only will this ensure that your furnace is running safely and efficiently, but it will also prevent further damage to your furnace. Remember, furnace repair can be dangerous, so it's best to call Zion Custom Air.
