Reasons to Get Your Blower Motor Cleaned

Just as your car needs regular tune-ups and scheduled maintenance, your residential or commercial furnace needs to be inspected and cleaned on a regular basis as well. Operating a vehicle that has worn-out belts or dirty oil can take a toll on its engine, and your air conditioning system is no different – running your unit with a dirty blower motor can negatively impact its performance and lead to costly repairs. While you may be able to perform basic maintenance tasks that improve your AC unit’s performance such as replacing the air filters or cleaning your ducts, you still need to schedule regular professional maintenance for more complicated tasks like cleaning your blower motor.

A Dirty Motor Blower Is Trouble

Even if you replace your HVAC filters regularly, over time dirt, dust, dirt, and debris can build up in your furnace blower motor, drastically reducing furnace efficiency, which leads to a higher energy — eventually leading to costly repairs. A dirty blower motor also increases the amp pull, which could result in burnt out capacitors, and can cause the motor itself to fail.

Clean air is crucial for good indoor comfort levels. When your blower motor is dirty it has to work harder to blow air through your ducts and vents, which reduces the ability of your filter to clean allergens, toxins, and pollutants from your indoor air, which can exacerbate allergies and asthma.

Professional Blower Motor Cleaning

Although it isn’t difficult to perform basic maintenance on other parts of your furnace, cleaning your blower motor is a complicated task that should be left to an experienced technician. Rather than attempting to do it yourself, it’s best to hire an expert to do the job for you. Here’s what to expect:

Inspection – During your consultation, your technician will discuss any problems you have been experiencing with your furnace to determine whether the issue is caused by airflow restriction, electrical, or other problem. They will ask about what type of maintenance your unit has received in the past, and then perform a visual inspection to get a better understanding of potential issues.

Blower Motor Removal – If your blower motor requires cleaning, the technician will shut off the power and gas supply to your system. After opening the access door to the blower motor compartment they will disconnect the wiring, remove the fasteners securing the blower assembly, and remove it from the compartment.

Blower Motor Cleaning – After separating your blower motor and fan wheel, your technician will clean the internal electronics and fan wheel using an air compressor or gas duster. If the fan wheel blades are covered with a thick layer of dirt and debris, they may clean it further with a garden hose.

Reassembly and Testing — Once the blower motor and fan wheel are thoroughly cleaned, your technician will put all the components back together and install it in its housing. After it is installed, they will test your blower to ensure it operates properly at every power level.

Cleaning your furnace’s blower motor is not an easy task. If your blower motor hasn’t been inspected or cleaned for several years, it’s time to call in the professionals.
