Reasons Why Your Furnace Might Start Squeaking

Do you hear a squeaking noise when your furnace turns on? Various issues can cause this, but luckily, it’s usually an easy fix. The following covers the causes of furnace squeaking and provides tips for keeping your furnace running smoothly throughout winter.

Loose Blower Wheel

The blower wheel is responsible for circulating air through your furnace. If it becomes loose, it can start to wobble and make a squeaking noise. To fix this issue, a technician will typically only need to tighten the set screw on the blower wheel.

Failing Motor Bearings

The bearings help the motor run smoothly. If they become worn out, they can start to make noise. To fix this issue, the bearings will need to be replaced.

Dirty Blower Wheel

If the blower wheel becomes coated with dust and dirt, it can start to squeak. To clean the blower wheel, a technician will remove it from the furnace and clean it with a soft cloth.

Loose Belt

The belt helps to rotate the blower wheel. If it becomes loose, it can start to slip and make noise. To fix this issue, simply have the belt tightened or replaced if needed.

Overworked Furnace

If your furnace is working overtime, it can start to make noise. To fix this issue, reduce the demand on your furnace by turning down the thermostat or using a space heater.

Tips for Keeping Your Furnace Running Smoothly All Winter Long

Schedule Regular maintenance

Having your furnace serviced by a professional once a year can help to prevent problems before they start. Maintenance will also extend the life of your furnace.

Change Your Air filter

A dirty air filter can cause your furnace to work harder than it needs to. As a result, it can shorten the life of your furnace and make it more likely to break down. Be sure to change your air filter at least once every three months.

Keep Your Furnace Clean

Dust and dirt can build up on your furnace over time. This can make it more difficult for your furnace to operate efficiently. To keep your furnace clean, vacuum around the unit and wipe the exterior with a soft

cloth.

Don’t Close Vents

If you close too many vents in your home, it can strain your furnace. As a result, it can cause your furnace to break down. If you have a room, you don’t often use, close the door rather than the vent. If your furnace is squeaking, there are a few things you can do to fix the problem. However, if the noise persists, it’s best to call a professional. A technician can diagnose the issue and make sure it’s fixed properly.
