As I mentioned earlier, I spend four days with the assumption that something is wrong with my air conditioner or that my ecobee can’t connect to it properly. Since I could not have a service on Friday because I was helping mom pack, so we agreed with the mechanic that he would come Monday morning.
I’ve managed through an extremely hot weekend, juggling the doors and windows open and close and turning on a portable air conditioner. I went to bed on Sunday thinking about why I had this feeling that the AC just does not turn on, and in the morning, I woke up and realized what could be wrong.
It was so stupid; I can’t even believe I was so dumb! But the first thing I did it the morning was marching to my ecobee and looking at the screen. Yes! It was showing just the “Heat” icon!
The ecobee has three modes: Heat, Cool, and Auto. I had it on auto in my Palatine home, and since I had it for many years, I forgot that you have to switch it explicitly! So I switched, and I turned the comfort setting for cooling one degree down to trigger the AC. It worked!
I left the message for the mechanics that all is good (they called me anyway to double-check), and then I spent the whole Monday with the mixture of joy and regret:).

Rest assured that I’ve done similar things, more than once.
