Get an Air Conditioner that Moves at More than One Speed

There’s a common misconception that turning down the temperature to below 70° will cool down your home faster. This just isn’t the case. Your air conditioner will only run for longer, using up a lot of energy to reach a temperature that’s lower than you need to be comfortable.

How Standard AC System Blower Fans Work

Most air conditioning systems have a fan that only moves at one speed automatically while the air conditioner is in use. The thermostat is set to turn the AC on once the temperature is too high. Once it hits 79°, for example, it turns on until it goes back down into the target range of 76-78°. It does the exact same thing if your target temperature is 74°. The fan will not move any slower or any faster no matter how low you set the temperature.

The Problem with the Single-Speed Motor

All of this starting and stopping of the AC system can really wear out the motor and many of the components. You don’t have much control over your comfort, even if you want to leave the system in “fan only” mode. And, it can be tough to keep temperatures accurate, since the air conditioner only has two settings: off and very fast.

The Variable Speed Blower Motor

Variable-speed systems work by automatically readjusting the speed of the motor as needed for optimal comfort and efficiency. The fan can remain running at a lower speed in order to keep temperatures within 1-2° of the setting on the thermostat.

And it uses less energy to do this. It does not have to keep shutting down and starting up, something that can strain the system and cause it to fail prematurely, potentially. All in all, you get…

  • Better Comfort
  • Higher Efficiency
  • A Longer AC System Lifespan
  • More Control
