A well-functioning heating unit is a key to a comfortable home, especially during winter. One often overlooked but vital component of your heating unit is the belt. The belt connects the motor to the blower and helps keep the entire system running smoothly.
Unfortunately, belts don't last forever and will eventually need to be replaced. But how do you know when it's time for a replacement? Here are four key signs you should contact furnace repair services about belt replacement.
1. Squeaking Noises
One of the most common signs that your heating unit needs a new belt is if it starts making squealing noises. These noises are usually caused by friction as the old, worn-out belt rubs against the motor pulley.
If you ignore the noise, it will only worsen until the belt eventually snaps. To avoid a dilapidating unit breakdown, it's best to allow furnace repair services to replace the belt as soon as you start hearing those telltale squeals.
2. Cracks and Splits
Another way to tell that your belt needs to be replaced is by inspecting it for cracks or splits. Even if no squealing noises are coming from your heating unit, small cracks can cause major problems down the line.
Once again, friction is usually to blame for turning tiny cracks into larger ones until, eventually, the belt snaps. Thankfully, you can avoid this problem altogether by allowing your furnace repair technician to regularly inspect your belt for any cracks or splits and replace it at the first sign of trouble.
3. Excessive Wear and Tear
In addition to cracks and splits, excessive wear and tear is another sign that your belt needs to be replaced. Your furnace technician will take a close look at both sides of the belt; if they see any fraying or excessive wear, they'll recommend a replacement. Remember, it's better to be safe than sorry, so don't think twice about heeding your technician's recommendation.
4. Misalignment Issues
If you notice that your heating unit is vibrating more than usual or making strange noises, it could be due to misalignment issues. Oftentimes, these issues are caused by an old or damaged belt that can no longer grip properly onto the pulleys.
As a result, the entire system starts to shake and vibrate, which can cause long-term damage if left unchecked. So, if you notice any misalignment issues with your heating unit, replace the belt immediately.
So, there you have it! Four key signs indicate your heating unit needs a new belt. Remember, replacing your belt is always better than dealing with a dilapidating unit breakdown. Don't hesitate to commission furnace repair services when you notice one of these telltale signs.
