Don't know what a blower motor is or why you might need it replaced? Don't worry! Many sewickley residents ask us this question. A blower motor is a critical component for powering the air circulation from your heating and air conditioning system. It is what turns on your system's fan motor, which pushes out hot and cool air from the unit into your home. It is the power behind your home's circulation, ventilation, heating, and cooling, ensuring the air in your house is evenly distributed. Common types of HVAC systems, such as electric and gas furnaces, air conditioners, and heat pumps, use a blower motor to move the air. When you set your thermostat to a specific temperature, your system will turn on, heating or cooling the air inside your home, and it's the blower motor's job to power the fan speed that produces air.
This internal component is inside your HVAC unit, but the location depends on the system model and type. The most common place for the motor in furnaces is inside the base of your unit next to the air filter. AC units, it is typically located inside the air handler. These two locations can also share a blower motor if you have a combination unit. For smaller, compact systems, the blower fan is located between the control board and the fan blade. Sometimes there are various wires and parts in the way of your blower motor, which can make a furnace repair or blower motor repair more challenging to manage on your own. When this is the case, it is recommended to use the expertise of a heating and AC repair company.
There are two types of blower motors: single-speed and multi-speed motors (also called variable-speed motors). A single-speed motor will run at one speed and turn off when the desired temperature is reached. A single-speed motor can run at different speeds to make up for a drop or increase in temperature. A multi-speed motor, or variable-speed motor, will continuously run at lower fan speeds to give your home continual air circulation. These are typically slower speeds and run steadily, making them energy efficient and saving you money on energy bills.
