Today's HVAC systems are radically different from the systems of decades past. Thanks to innovative breakthroughs and continuous improvements in HVAC technology, HVAC systems are able to bring optimal comfort and efficiency to the average household. Among these improvements is variable-speed technology. Unlike traditional HVAC systems, the equipment used in variable-speed systems can operate at various speeds, resulting in reduced energy consumption and improved home comfort.
While you probably know many of the benefits of having a variable-speed HVAC system in your home, there are a few other benefits you probably wouldn't expect. The following takes a closer look at these benefits.
Improved Humidity Control
During the summer, HVAC systems offer a great way of keeping your home's indoor air from becoming too humid. However, your HVAC system can only dehumidify the air as long as it's running. Traditional single-stage HVAC systems don't operate their compressors continuously, resulting in an increase in relative humidity when your HVAC system isn't operating.
Unlike traditional HVAC systems, variable-speed HVAC systems are able to run continuously, keeping your home's indoor air drier and more comfortable for longer periods.
Reduced Likelihood of Short Cycling
Over the course of a typical summer day, your HVAC system's compressor may cycle on and off three to four times an hour. A sharp spike in temperatures and a corresponding increase in cooling demand can cause your compressor to cycle more often. This could lead to short cycling, where your HVAC system cycles so frequently that it causes compressor wear and a noticeable increase in energy consumption.
HVAC compressors are most effective and energy-efficient when they're allowed to run for as long as possible. Variable-speed HVAC systems allow for longer compressor run times by varying its power output, allowing the compressor to run at half or even a quarter of its full speed under light loads.
Excess noise is a common issue that many households have with their HVAC systems. While the usual causes can be traced back to a suboptimal duct design or poor HVAC system placement, the blower fan motor can also be to blame. With most single-speed HVAC systems, there's little that can be done about a noisy blower fan.
Variable-speed HVAC systems deal with this problem by utilizing a variable-speed blower fan. With your blower fan able to operate at lower, softer speeds, you'll be able to enjoy a quieter HVAC system without completely sacrificing indoor comfort.
