How A Variable-Speed Blower Can Contribute To System Efficiency

Posted On: January 01, 2012

Most traditional furnaces and air conditioners come with a single-speed blower. This limits them to only running on one setting – high. During mild weather, this can be overkill, wasting energy by outputting too much air when a lower setting would suffice.

If you’re in the market for new heating and cooling equipment, one option you should look into is a variable-speed blower. These blowers allow the equipment to run at more than one speed, alternating between settings depending upon the current heating or cooling load. Variable-speed equipment offers a number of benefits over traditional single-speed equipment including:

  • Improved Efficiency. Even in areas of the country with hot summers or cold winters, for the vast majority of the year temperatures are relatively mild. Systems with variable-speed blowers adjust for mild temperatures by running at a lower setting. This improves efficiency, helping you save money on your heating and cooling costs.
  • Better Air Quality. Rather than running for short bursts of time on the high setting like single-speed equipment, variable speed equipment tends to run on low for long, steady periods of time. As a result, air is continually passed through the air filter, helping to remove particles and contaminants.
  • Better Humidity Control. Again, because variable-speed equipment runs for long periods of time on the low setting, it provides superior control over indoor humidity levels.
  • Quiet Operation. In many cases, when operating on the low setting, variable-speed blowers are so quiet that you won’t even realize they are on. Additionally, unlike single-speed blowers that start on high with a loud gush of air, variable-speed motors slowly and quietly ramp up speed, eliminating excess noise.
