New electric motor reduces energy consumption up to 80%

My 5 year old HVAC system has a multi-speed multi-stage pump system,, and,, wait for it,, a variable air handler fan.
It will cycle from like 25% I think they said up to 100% depending on the call from the "smart" thermostat.

The newest and most efficient systems all have variable speed brushless DC PM motors. A well you should be looking for a high turn down ratio which means the heating/cooling starts at 5% and progressively ramps up to 100% based on demand. The high turn down ratio to 5% ensures a lower stack temperature in heating mode and a lighter compressor/condenser load in cooling mode.
