Standard heating and cooling systems are constantly starting and stopping, which can cause uncomfortable temperature fluctuations. Variable Speed Units maintain consistent temperatures in your home by running at lower speeds for lower periods of time.
Stopping and start the unit consumes approximately 8 times more energy than just keeping the unit running for longer period of times.
Variable speed units offer better temperature control, better humidity control, better air filtration, quieter operation, and lowest cost per minute.
This video shows an example of how these units operate. We will also give you some example about when is better to choose a multiple speed unit over a single-stage or two-stage units.
