We had an AC drain pan in the attic that was filling with condensate and overflowing. It wasn't an emergency, but I wanted it fixed before it became one. A technician came the next morning, well before the scheduled time and fixed the issue within an hour. He recommended we have the outside unit cleaned and he was 100% correct. Within minutes of the cleaning, the hottest room in our house was colder than ever. All prices were quoted up front and there were no surprises.
