Signs That Your HVAC Blower Motor Needs to Be Replaced

When temperatures begin to climb or go down in Edmonton, the last thing you want is a broken HVAC system. Thus, finding and fixing the issue as soon as possible is the best course of action if your HVAC system isn’t blowing cold or hot air or is acting strangely.

This will allow your house to swiftly recover and return to a comfortable state. A variety of factors can trigger a malfunctioning HVAC system, and occasionally the fixes are simple. But sometimes there is a more serious problem, such as a broken component that has to be replaced. The blower motor is a crucial part of your air conditioner, and it must be in excellent condition to maintain your home’s level of comfort and air purity.

Fortunately, Edmonton’s top-rated HVAC contractors can replace or repair your broken blower motors. Here is a detailed checklist to help you decide whether the blower motor in your HVAC system needs to be replaced.

Weak Airflow

In general, this is the first indication that a blower motor in a central air conditioner is malfunctioning. Weak vent airflow may indicate that your motor is unable to push hard enough to meet the thermostat’s temperature.

It’s important to remember that this doesn’t necessitate an immediate blower motor repair. A poor capacitor or the buildup of dust are two more factors that might cause poor airflow. To be sure, you should contact a specialist for HVAC maintenance or repair.

Unusually High Energy Bills

The part of your HVAC system that consumes the most energy is the blower motor. Your utility rates may have suddenly increased due to an old, inefficient, or dirty motor that needs to work harder to circulate conditioned air around your home.

It might be advantageous to switch to a modern, variable-speed model if your air conditioner is much beyond its prime or is powered by a single-speed motor. To properly chill your home, the new motor will automatically regulate its energy consumption. This prevents energy waste and lowers your energy costs.

Strange Sounds

Many strange noises coming from an HVAC system might be a sign that the blower motor is malfunctioning. While some weird-sounding problems can be fixed by a professional, others could call for the motor to be replaced. For instance, screaming or squealing noises might indicate that the blower motor’s bearings are broken or that the belt is faulty.

A loose or damaged component could be the cause of the motor’s pounding, clanging, or rattling noises. Loud banging noises are particularly disturbing. They frequently indicate that something is broken or unconnected. The blower motor may need to be replaced as a result.


There are several potential causes for your blower motor to overheat. The motor’s surrounding dirt and filth might build up and stop it from venting. This can lead to heat buildup over time. By having a professional service your motor, you can resolve this issue.

Increased energy consumption, overheating, and malfunctions may result from the added pressure. The best course of action in this scenario is to purchase a new blower motor. You’ll notice a few undeniable indicators if your blower motor is overheated.

Strange Smells

An electrical burning odour emanating from the indoor AC unit might indicate that the blower fan motor is overheated. The safety function of the system should shut off the device automatically in this situation. Additionally, you may notice that the blower fan is spinning more slowly than usual.

An electrical burning odour from the outside might indicate a problem with the condenser fan, which might lead to a dangerous compressor overheating. An item inserted inside the device may cause it to overheat and emit a burning plastic odour. In either scenario, turn off the appliance at once and call a technician to inspect the HVAC system.

Replacing Your Blower Motor

If you want to replace your blower motor, getting in touch with an HVAC firm will help you choose the right replacement model and verify that it is fitted correctly. The kind of drive, the motor’s diameter, the motor’s rotational orientation, the horsepower, the voltage, the speed, and the size of the capacitor are all elements that an expert will be able to identify and use to assist in discovering the appropriate replacement.

They can offer you an estimate and direct you toward the most appropriate, cost-effective versions that will work in varied environments. Then you can arrange a time for installation.
