No matter what temperature I set on the thermostat...

No matter what temperature I set on the thermostat, the temperature inside kept climbing. I thought I needed a new thermostat. Turns out, after a long investigation by Micah - the freon was so low that the AC froze up. In order to recharge the freon, the frozen parts needed to completely thaw - so very early the next morning, Micah was back to check everything out all over again, he restored the freon to the correct level, and all was well. Very pleased to have a cool house once more!
