It starts as a slight rattle that you try to ignore. Within weeks that rattle now sounds like there is a train plowing through your basement every time the HVAC system turns on. What is causing this noise? An imbalanced blower motor is the culprit. No matter which system you are using, air conditioner or furnace, the blower motor is always in operation. This fan circulates air through the duct work in your home, and the slightest disturbance in its function could result in a massive part failure. At Four Seasons, we have recently noticed that many of the homeowners encountering this problem have a similar root cause to the issue. The true problem lies within the duct work, but the good news is, this doesn’t have to be a problem in your home too.
Debris in the Blower
When we send out a technician to run a call like this, they often find that the motor became unbalanced because a bit of debris got into the blower compartment. Candy wrappers, old receipts, and even plastic army men have been known to find their way into the blower motor. These tiny objects have the power to destroy this rather expensive part of your system, and they traveled through your duct work to do so.
Debris in the Ducts
The ducts in your home feed into nearly every room in order to deliver cooled or heated air and return unconditioned air back to the HVAC system. Therefore, any debris floating around your home can become lodged in the duct work. Over time, this debris can travel to the HVAC system and gain access to your blower motor. Luckily this can be prevented in two ways.
Filter Changes and Duct Cleanings
First, make sure that you check the filter compartment regularly for any debris that may be trying to get into your blower. Every month when you go to change the filter, simply take a peek inside, remove anything that may cause a problem and insert a new clean filter. The second thing you should do is have Four Seasons Heating and Air Conditioning perform a professional air duct cleaning in your home. This service will remove the years and years of buildup from the inside of your ducts and truly help you prevent HVAC problems that could arise in the future. These two practices combined with a little help from Four Seasons will keep your blower compartment empty of anything that could harm this valuable system component.
