I called around 8AM to ask for a repair as my unite had stop cooling. I was NOT given a time or a time frame other then the tech would call 30mins before arriving. Once there he told me that there was nothing wrong and the unit started cooling again. I held him there just to make sure and again it stop cooling. Come to find out I needed a new thermostat. Thank goodness I did not let him leave. My family and I would have spent a July night with out. I have never had to pay for a AC unit repair so not sure how much it should have cost me but I think the thermostat was WAY over priced. Don't' know that I will be calling back.
