He installed the smart temperature control for me that morning
Just a couple months ago, I observed that there was something wrong with our gas furnace. I had received some gas bills that seemed way higher than usual! At that point, I started paying a little more attention to how long we would leave the furnace running and the temperature settings; Despite being conservative with my temperature settings, I observed that the fan was running most of the time anyway. After another high gas bill, I decided to call a heating & cooling worker to come take a look at the gas furnace for me. When he looked at the gas furnace, the heating & cooling worker did not detect any concern with the gas furnace itself, finally, he realized that the concern was with the temperature control instead of the furnace. It turns out that the temperature control was malfunctioning. That caused the gas furnace to work much harder than it needed to, and ultimately, the heating & cooling worker said that it was time to replace the temperature control. He said that we should go with a smart temperature control, as it will allow me to save both energy & currency. After a few months of overpaying on the gas bill, I was gleeful at the prospect of saving some currency. He installed the smart temperature control for me that morning. Immediately, I saw a sizable decrease in our energy usage! I was happy to see how low the next heating bill was.
