We spent the weekend in Las Cruces and it only got to about 85 outside. This was the first test to see how well the ACs worked and I gotta say Im a little disappointed. During the hottest part of the day the inside temp only got to 74. We had the main AC and the one in the bedroom on high all day and I was hoping to see somewhere around 68. Makes me wonder how they are going to perform during the 100+ El Paso summer.
