Eliminate the Loud Noise from My Furnace

Various factors may cause your furnace to act strange and make loud noises. When this happens, it signals that it needs maintenance, and you should call a professional for furnace repair in Carmel, IN, quickly.

Here is a list of the six most common types of loud furnace sounds, along with troubleshooting tips: 

Points of Common Types of Loud furnace Sounds.

Screeching Noises

Screeching sounds commonly indicate issues within the blower motor or the blower fan. The metallic bearings need adequate lubrication to reduce friction and resistance during movements. You can resolve this issue by adding a suitable lubricant on your own, or in case of a broken part, contact a technician right away. 

A damaged motor belt can also lead to high-pitched screeching sounds which need immediate attention. Shut down the furnace, and let it cool off; call a professional for a thorough inspection of the blower motor, fan, and motor mount. 

Squealing Sounds

When the blower belt of your furnace becomes loose, it will give rise to a squealing sound. Apart from this, a squealing sound can also be produced due to dry moving parts or shaft bearings.

With overtime usage, the blower belt needs to be replaced or adjusted. Unlike the fan belt, replacing a damaged blower belt is not something you should do on your own. It is better to call a professional to make the necessary adjustments or replacements.

Scraping Sounds

Scraping or clunking sounds from your furnace indicate a problem with the furnace’s blower wheel. The most common cause of this sound is a loose blower fan hitting against the blower house casting.

If you hear these sounds, turn off your furnace immediately and call an HVAC professional for heating service repair in Carmel, IN. If the wheel is slightly damaged, the repair costs will be minimal, but if the blower fan is broken, it will need a heating installation, Fishers.

Banging Sounds

When your furnace burners are dirty, you may hear a loud banging sound when you turn it on. Dirty burners delay the ignition and can cause the gas to build up and explode when the ignition turns on. You can solve this problem with annual maintenance by ensuring that these burners are inspected and cleaned.

Booming Sounds

A thud or booming sound is generally created when the metal air ducts expand or contract due to temperature changes. This process is natural and does not inflict any damage to your unit, but if it becomes annoying, you can contact a professional furnace repair in fishers, IN.

Rattling Noises

Rattling noises coming from the furnace indicate a loose panel or screw in the furnace. To solve this problem, you can tighten the panel using a screwdriver after turning off the power to your furnace. But if this doesn’t do anything, you have a faulty heat exchanger. You will need a professional to help you with the heat exchanger as it can lead to carbon monoxide leaks in your home.
