Variable-speed technology is a new innovation that can be a game-changer for future heating and air conditioning systems. Anderson Refrigeration, Inc. shares an overview of what variable-speed technology is and how it can benefit your home.

What Is Variable-Speed Technology?

A typical HVAC system works by turning on and pumping out conditioned air when a difference in room temperature is detected. It turns back off once the desired temperature is reached, then repeats this process when the room temperature changes again. Operation if this type of system is either off or on; there’s no transition between these states.

A variable-speed system controls the HVAC unit at the compressor stage, providing more precise control not just of the heating and cooling output, but also of how much work the compressor needs to do. It consists of three parts: a system controller, a motor control drive and a variable-speed compressor. The system controller is like the brains of the system, interfacing with the rest of the HVAC unit and the motor control drive. Frequency modulation allows fine control over the compressor. Instead of on-and-off stages, the compressor can be set to anything in between.

The Benefits of Variable-Speed Technology

Heating contractors who’ve checked out variable-speed technology all agree that it’s a significant improvement over traditional compression systems. A variable compressor workload means less energy use, which can help you save on your energy bills. The precise load matching can dramatically improve HVAC efficiency and HSPF (Heating Seasonal Performance Factor) and SEER (Seasonal Energy Efficiency Ratio) ratings.

Variable-speed technology also gives you more precise control over indoor humidity, virtually eliminating stop-start operation, or what is known as “short cycling”, which helps prolong the HVAC system’s life span. Efficient air circulation coming from the compressor can also help improve indoor air quality by driving pollutants into the filters. Not all systems can be retrofitted with variable-speed technology, but you can ask your local HVAC contractor to inspect your heating and cooling system to be determine if yours can,
