Please set at no lower than 74 degrees to prevent the air conditioning from malfunctioning.
Palm Springs sunny weather brings day after day of sunshine and warm temperatures hovering in the 90 to 100+ degrees or more during the daytime in spring, summer and early fall.
By setting the house temperature at 74 degrees, you will be comfortable, and the air conditioning will not overwork, break down, freeze up or otherwise quit working. We want you to enjoy your vacation time not waiting for a technician to come to repair the air conditioning system. So please, for your comfort, and to prevent break-down of the mechanical system, set the air conditioning at 74 degrees and no lower. Lower settings do not produce cooler air; it only makes the air conditioning run longer.
Keep in mind that when the temperature outside is 100 to 110 degrees, and you cool a room to 74 degrees, that's a 24 to 34 degree improvement. And that's a big chore for any air conditioning system.
