The Benefits of Variable-Speed HVAC Technology

If you’re planning to upgrade your home’s HVAC equipment, you’ll want to investigate variable-speed technology when you’re comparing different replacement options. Thanks to industry advancements, there are variable-speed furnaces, compressors and air handlers available that are radically different than traditional single-speed versions.


Since they only have one speed, traditional components always run at 100 percent capacity, while variable-speed HVAC equipment can adjust its output incrementally to better meet your home’s heating and cooling needs. This capability brings you some impressive benefits including:

Better Energy Efficiency

An HVAC system equipped with variable-speed components starts up and runs on low speed and only ramps up when extra output is needed. Operating at a lower speed saves you energy – just a 20 percent speed reduction can cut your equipment’s energy use by as much as 50 percent.

Greater Comfort House-wide

Single-speed components cycle on, run full blast until the thermostat’s temperature setting is satisfied, then cycle off again. This full-on then off cycling can result in hot and cold spots and temperature variations that erode comfort. Variable-speed HVAC runs on low for longer cycles, so you’ll experience fewer temperature peaks and lulls and more consistent comfort throughout your home.

Improved Air Quality and Humidity Control

With variable-speed HVAC, your system can provide better indoor air quality and humidity control. The equipment’s extended cycling helps your heat pump or air conditioner remove airborne moisture better to keep humidity in check during cooling season. If you add an air cleaner to your HVAC, these longer cycles can boost filtration to give you a healthier air supply.

Prolonged Equipment Lifespan

Running full blast and cycling on-and-off repeatedly is bound to take a toll on your HVAC components’ lifespan. When you have variable-speed equipment that operates on a lower speed and doesn’t start up and shut down as often, there’s less wear and strain, so your HVAC will tend to break down less often and last longer.
