Has everybody had a difficult time getting their AC to maintain a cool temperature in these houses? My thermostat says it's 80 degrees in here. I have had somebody out here every year, and one year they say I don't have enough coolant, and the next year they said I had too much, and that basically they didn't see a problem. I took Rob's good advice and made sure we kept the interior doors open to get the hot air back to the return, but it's been getting hotter, and it isn't even July yet!! Who do you all call for service?
