I live Florida. I moved into this home last April and we put a lock on the thermostat contained by May or June and since then the bill have gone up at least a $100 respectively month. Is this box preventing the thermostat to run properly and contributing to the high bills?

Answers:    Yes, if your thermostat lock looks similar to a box with vent holes, the cool nouns doesn¡¯t reach the thermostat as briskly and the A/C runs longer. The summer months are also the hottest months, and you¡¯re A/C is working much more¡ªthat will cost you more. With the cooler weather coming, you should see your electric bill coming down.

I¡¯m not sure why you put in thermostat locks, but you might be better served by a digital thermostat. There are also commercial digital thermostats near no adjustment knobs or buttons for the kids to play with¡ªthese are more expensive.
