We’ve gotten dinged lately on our air conditioning limits.  We allow guests to adjust the thermostat within the range 72°-80°.  Most of the time, since we’re in MS, it’s in cooling mode.  Some guests, if allowed, would and have set the thermostat down into the 60s, and neither of the two units would ever cool to those temperatures.  So, we include the following everywhere we can in the listing:

Because the air conditioning units are residential and not commercial, we protect them by limiting the minimum cooling temperature.  Past guests have set the temperature far below generally accepted norms, well below 70º.  The units would never achieve those temperatures in the Mississippi heat and they've frozen up, resulting in no further air conditioning for days and costly repairs.  Thanks for understanding.  If you prefer inside temperatures lower than this, please do not book with us.

What else can we do to protect our A/C units?  They’ve frozen up before, which renders them inoperable for days, the guest has to leave, we have to give a refund, and then we have to have them serviced, which obviously costs, and if a leak is discovered, costs even more.

Any advice is appreciated.
