Advances in HVAC technology continue to make our daily lives more comfortable and convenient. If your home still uses a traditional on-off blower motor, you are missing out on the benefits of a newer variable speed blower. Here are four reasons you should consider installing an HVAC system with a variable speed blower.

1. Improved Air Quality

Still air is the bane of indoor air quality. Even if your HVAC system features a whole-house air purifier, it can only clean the air while it's moving through your home. Variable speed blowers allow air purifiers to work constantly because they circulate air at all times. When heating or cooling demand is low, variable speed blowers run at a slow speed to save energy and reduce noise.

Another common whole-house air quality device is a humidifier. Like air purifiers, humidifiers only work while air is moving through them. Variable speed blowers allow humidifiers to run continuously so that your air isn't dry and stale when your HVAC system isn't running. Humidifiers and air purifiers also work more effectively on air that moves through them slowly.

2. Enhanced Comfort

Since traditional HVAC blowers are limited to running at full speed or not at all, there are limits to the level of comfort they can create. An on-off style blower will cycle frequently and introduce a significant temperature differential each time it starts up. These factors lead to poor air mixing and may cause hot and cold spots in certain rooms.

Variable speed blowers have much more precise control over the air mixture in your home. A good air mixture creates a more consistent temperature in your home and allows you to be comfortable in every room. With more even temperatures, better air filtration, and enhanced humidity control, variable speed blowers improve every aspect of indoor air quality.

3. Greater Energy Efficiency

As you might imagine, an HVAC blower that runs at lower speeds will use less energy than one that can only run at full capacity. Traditional blowers also cycle on and off much more frequently than variable-speed blowers. These factors combine to make the energy use of an on-off blower much higher than should be necessary to heat and cool your home.

A variable-speed blower can help you save on energy costs by changing your usage habits. A more consistent air temperature means you're less likely to adjust the thermostat to stay comfortable. Even a difference of a few degrees can cause a noticeable difference in your energy bill.

4. Longer HVAC System Life

Energy savings are an immediate benefit of a variable speed blower motor, but these systems are also a more valuable investment than those with conventional blowers. Variable speed blowers are rarely pushed to running at full speed, so they take longer to build up wear and tear. As a result, you are likely to get more years of service out of a variable speed blower compared to a conventional system.

Another thing to consider is that a new HVAC air handler with a variable speed blower will come with a warranty. If your current system is out of warranty, upgrading to a variable speed system with a strong manufacturer warranty will give you peace of mind that you're covered if repairs are needed.

Variable speed blowers are just one example of the ways that modern HVAC systems have improved over the years and provide convenience to our lives.
