Want the HVAC system maintained

The other day, I was a little bit disappointed when one of my old college friends came over to help install our smart temperature control. When he was just about finished working on it, he went and dropped it. It turns out that it broke, and I could not believe he broke our thermostat that I just purchased last week! He apologized a ton plus he said that he would buy me a current smart temperature control. He stayed true to his word, and ended up purchasing me something a lot more high-priced than what I got. He said this was no cheap temperature control, and it would not break just by falling on the ground prefer. I definitely didn’t want to test out that theory. So he installed this smart temperature control, but I was thinking I might be better off calling the professionals myself. He didn’t mess up this time around. I assume he was being extra careful, because he bought it himself. With this current smart temperature control that he got, it was such a nice improvement to our HVAC system that we purchased a few years ago! This thing allowed me to control the temperature control settings remotely from pretty much anywhere I was, however also, it gave me notifications about when I should change the air filter, plus when I should get our HVAC system maintenanced by our heating and cooling professional. I particularly cannot express how helpful this is, because I would just randomly get our HVAC system maintenanced every so often, now I know the exact date when I need to get my HVAC system maintenanced. Also, with the suggested power saving settings on the thermostat I am saving a good deal of money on our utility bills. Maybe it was a good thing that he dropped my thermostat!
