Smart thermostat alerts me when cooling system stops laboring

I was at work when I got an alert on our iphone, however i diagnosed it… The alert was from our smart thermostat at home. It was telling me that our beach house was over 70 degrees. I tried turning the thermostat down remotely however our beach house stayed at 70 degrees. I had noticed that it was kind of hot that morning when I was getting ready for work although I hadn’t thought much of it, then however when I diagnosed our smart thermostat again, on our iphone, I saw that it was now 68 degrees and climbing. I called our Heating, Ventilation, and A/C supplier and stressed an air conditioner repair then I explained the situation to our boss. Thankfully our boss was understanding and let me go beach house to check on our cat, and when I got beach house our cat was just fine… She was stretched out on the cool linoleum floor in the dining room to cool off though. It was overheated in the house. Thankfully the Heating, Ventilation, and A/C supplier showed up about an second after I got home. They fixed our a/c rather hastily and the beach house started cooling off again, my cat got comfortable again too. I am absolutely glad I was able to take care of it that same morning. I am grateful that our smartphone alerted me to this temperature extreme. I had set it to alert me. Thank God I did. If not, I wouldn’t have known our a/c had broken down until I got beach house from work, then by then our exhausting cat would have absolutely been suffering. It also might have been too late to get an Heating, Ventilation, and A/C supplier out that same morning.
