Joe,
Good luck on the air conditioning. No one should have to go through that stuff to get something fixed. That is why I stay with the same company that has did mine for many years. I know they will do a good job. A couple of years ago they sent a new guy out to do my Fall check and he didn't do much of anything and I told him I wanted the pump and everything checked. He informed me he didn't do that so I called the company. They fired him a week later and sent another one of the techs out to take the unit down and do the complete service. He told me it wasnt just my call that got that guy fired, that every service call he went on they got complaints about him being rude and not fixing problems. I am thinking of having my vent pipes cleaned which will be extra but they have never had the dust cleaned out of them in all these years,
Ron
