What is a multi-speed blower?
What is a multi-speed blower?
Rather than operating on the all-or-nothing principle, multi-speed blowers run at different velocities according to the temperature requirements of your home. They power up at full throttle and switch to a lower speed to maintain the desired temperature.
How does a multi-speed blower work?
Multi-Speed Blower Motors When the heat drops below the thermostat setting the furnace starts up and blows warm air throughout the house. A multi-speed blower basically has a speed for cool and a speed for heat. This is more efficient and the home’s comfort level is more even throughout the day and night.
How do I adjust my AC blower speed?
You can increase or decrease the blower speed by slightly adjusting the pulley on the blower drive motor. To increase blower speed, slightly loosen the setscrew that holds the pulley to the driveshaft. Move or turn the pulley clockwise on the shaft one turn, then tighten setscrew.
What is the difference between variable speed and ECM?
The word “variable speed” refers to the blower motor that is inside your air handler or furnace. It is an ECM (electronically commutated motor). An ECM is an energy efficient, low-maintenance option and it can help to reduce your overall operating costs.
How many speeds can a single speed blower motor go?
Single-speed blower motors can only work at 1 speed: HIGH (100%) Multi-speedblower motors can work at up to 3 speeds: LOW (30%), MEDIUM (70%) and HIGH (100%) Variable-speed blower motors can ramp up/down according to the level of cooling needed and can hitany speed between 0% to 100%
Where is the blower motor in an AC unit?
Note: To be clear, the AC blower is controlled by an electric motor which is housed inside the blower/fan. So when we say “blower motor”, we’re referring to the two parts as one complex component. The blower motor sits inside the “air handler”, otherwise known as the indoor unit (see below).
What are the different types of blower motors?
Single-speed blower motors can only work at 1 speed: HIGH (100%) Multi-speed blower motors can work at up to 3 speeds: LOW (30%), MEDIUM (70%) and HIGH (100%) Variable-speed blower motors can ramp up/down according to the level of cooling needed and can hit any speed between 0% to 100%.

Is the air handler blower a variable speed motor?
The blower has a variable speed ECM motor.. Despite being set to the lowest recommended airflow speed, there is still an excessive amount of air noise from the vents on the floor. Not better with removing the vent cover or changing the filters. Sound measures at 58-62 dB.
Can you change the speed of an air blower?
Yes you can but we think its just better to know that it can be done whats involved with a simple speed change of your air blower for your furnace air conditioner or heat pump. Ryan from Environmental Heating & air of nc gives you the color codes and speed of those wires.
What happens if the blower speed of an AC unit is too high?
If a blower speed is set too high, your AC might not be operating optimally. This is because the evaporator coil will not be able to adequately dehumidify the space in need of cooling. On the other hand, if the blower speed is too low, your evaporator coil is at risk of “freezing.”
How much air handler speed does an AC unit need?
For peak performance, most AC manufacturers suggest that 400 cubic feet per minute (CFM) per ton of air conditioning should be used, meaning that 800 CFM should be moving through the evaporator coil for a 2-ton system, and so on.
