What is Variable Speed?

We often get the question “Why should I go with a variable speed blower motor over a standard single speed blower motor like the one I currently have?”… The answer is simple; more energy-efficient (uses 10 times less energy than your current single-speed motor), helps with uneven temperatures, better air filtration & dehumidification, & is much quieter!

Instead of the temperature spikes you would see from your current system (when in “Auto” mode – or like driving a car in the city… start stop, start stop… etc) you see a more consistent temperature because the system is constantly moving the air. Your current system will call for heat; the furnace will warm up, the fan will come on; it will heat until it satisfies the thermostat, then the heat shuts off; and the fan will continue to run until the system has cooled down. When it kicks back on; you typically notice a cold blast of air.

With a variable speed blower motor, it will constantly be moving the air, so you won’t have to worry about those cold blasts when it kicks on. It’s a much more comfortable solution for your home and people who don’t have it; just don’t know what they’re missing until they have it! Plus, when you run the variable speed blower motor continuously; it’s easier on the motor. It’s like a car with 100,000 highway miles (variable speed motor) VS a car with 100,000 city miles (single-speed motor). The car with 100,000 highway miles is going to be in much better shape than the car with 100,000 city miles that has been driven hard.
