Here is a story you may like: I got a new A/C and Sense picked it up 2 weeks into operation. While the new equipment kept the house nicely cool I did not understand why the power meter showed an average cycle of only 4min40sec. Even during a heat wave it still ran for this short cycle and then stopped for 4-5 min. Not good I was told. Constant stop and go wears down the equipment and condensation water would not drain keeping humidity at higher level than necessary. I called the installer, a technician came, I showed the data, he came back with a Lennox rep and 2 weeks later the installer swapped the equipment for a smaller size at no cost and cut a check for the size difference! Sense more than broke even instantly only three month after install….
