A variety of factors contribute to an air conditioner’s energy efficiency. One important factor is the motor, also known as the air handler. Many homeowners are choosing to install variable-speed air handlers as part of their air conditioning systems. Here are a few reasons why:
- Greater efficiency. Because it runs at different speeds depending on the cooling requirements at the time, a variable-speed motor uses much less energy than a standard unit with only one fan speed. This significant difference in energy use often results in an efficiency gain of 1 SEER when compared to an otherwise identical system. (The higher the SEER rating, the better the unit’s energy efficiency.)
- Quieter operation. With your current system, you may put up with the sounds of the equipment kicking on. With a variable-speed blower, the fan slowly increases or decreases speed so you don’t experience those sudden noisy blasts.
- Improved comfort. You’ll notice less fluctuation in temperature when the system has the flexibility to turn the motor to low, medium or high as opposed to simply on or off.
- Better air quality. Even when cooling isn’t necessary, you can set up a variable-speed air conditioner to circulate air throughout the home all the time. This helps to remove pollutants from the air on a continual basis.
The technology of variable-speed A/C units isn’t new — it simply hasn’t been used in the residential market for long. If you’re shopping for a new air conditioner and considering your motor options, contact an AC Pro certified contractor with your questions.
