@Denise1406 Oh the joys of hosting in south Florida in the summer time..I can't wait for summer to be over.
I have 7 units in Florida and every summer its a battle of wits with guests and the AC. Not so much from in state guests as they get it, however the northerners and mid westerners want to turn the unit into an igloo and then head to the beach for the day 😒
I have been using Nest E learning thermostats. We don't use the learning feature however I am able to lock the thermostat so the guest can't go any lower than 69 and a high of 79 becuase not everyone wants to be freezing, myself included.
Nest also has the eco mode feature so that when the unit is vacant the temp will rise to a warmer temp and will then come on at their set temp when they return. This is saved a lot on electricity but also wear and tear on the systems. When the heat index is 105 and they turn it to 69 the AC just runs and runs never getting below 72.
I did stop using the ECO mode in this heat beacuse if the unit goes up to 75 while they are away and the want it at 69 it will take forever to get it to temp. I just keep an eye on it and when its set to 70 and the unit is vacant I will raise it up a bit so it can shut off and have a breather.
After replacing 2 systems for 8K each, I got the Nests becuase if you don't control it they will try to set it to 55 and have the sliding glass doors open.
Some hosts like the Ecobee which is similar I believe. Defintiely look into getting something before your AC gives out.
