Your furnace can make a lot of unusual sounds, but of all of them screeching is one of the most concerning. If your furnace is screeching, it can indicate a problem with the blower motor. Since the blower motor is a significant component within your unit, you want to address any screeching metal sounds sooner rather than later.
You can give our team a call for furnace repair in Warren, MI. We can inspect your furnace based on your concerns and offer a variety of solutions. In the meantime, you can keep reading to learn more about what screeching sounds inside your furnace mean and why they are dangerous.
About Your Furnace Blower Motor
Your furnace blower motor helps to distribute heated air into your home. When it’s working at peak condition, it helps your home get warmer quickly and efficiently. But if your blower motor isn’t working the way it should, it can cause a lot of problems. A screeching blower motor can lead to the furnace overheating as warm air backs up into the system instead of being distributed. It can also affect your comfort if your home doesn’t get warm enough.
If you notice your furnace screeching, you should turn it off and leave it off until one of our technicians can take a look. If you allow the screeching to continue, that means metal parts are grinding against one another. This can lead to significantly more damage than if you address the problem early. In some cases, it’s possible to repair parts on a blower motor. But if the damage is too significant, our team needs to consider replacing the entire component.
Screeching Metal Sounds
When your blower motor is well lubricated, the parts can interact together easily. But if lubrication turns into grime because of dust buildup and the metal bearings wear down, the metal components can grind and screech as they try to work together. Screeching can also be accompanied by other signs that your furnace is struggling. You may notice unusual smells or the blower may not turn on and off like it should during heating cycles.
Addressing Furnace Issues
Your blower motor can be a very expensive component to replace. Depending on your furnace’s age, it may make more sense to replace the entire furnace instead of just the blower motor. Our technicians can look at your entire system and make a recommendation based on your system’s overall well-being. If the rest of the system is in good shape and your unit is still fairly new, we may replace that one part. In fact, it may even be covered by your manufacturer’s warranty.
But if your furnace is over 10 years old and other components are showing similar signs of wear, we may recommend installing an entirely new furnace. Another reason you might consider replacing your entire system as if the repair for your blower motor exceeds 50% of the cost of a completely new furnace. Even if you have a new blower motor, the other parts are going to continue to wear down. It’s possible that you could make a very costly investment and then have to replace your furnace just a few years down the road because of other problems.
