Since installing the NEST thermostat a few months ago in our 2K sq ft house, our electric use has gone UP by nearly 1K kWh/month! Duke energy came and did a review/audit and said the NEST is allowing too many cycles per hour that the system is never reaching efficiency. Not to mention it is killing the condenser! It chases one degree all night for five to ten minutes at at time! This is a serious design flaw and I am shocked it hasn't been addressed! As a Risk expert, it frightens me that Google, who has more data on everyone than anyone, cannot properly identify and address such huge risk! There are a lot of people out here angry about their AC/heating units killed by Nest and it is only a matter of time before the attorney smell the money to be made!
What is the fix? Yes, the system is big and powerful, so it cools down quickly. But that also means it takes more power to start. The house can never get fully dried this way either. I have shut all the vents near the thermostat to try and force longer cycles, but it hasn't made much difference. Is Google ever going to fix this or do I just rip it out and buy as unit that has an adjustable/better differential? Can't Google come up with an update!?
