Did you know, generally, the average temperature differential of an air conditioning system is 20 degrees, with the best systems maxing out at 24 degrees. On an extremely hot day, if you’re trying to set your thermostat at 75 and it’s 100 outside, the air conditioning will run constantly and never reach the desired temperature on the thermostat. This doesn’t mean your air conditioning isn’t working, it simply means it’s too hot outside. More information can be found on the HSA Resource page http://onlinehsa.com/
