We contracted Stephan to replace our furnace and air conditioner back in fall 2008. They promptly got to work to replace the furnace for the winter and then ripped out our air conditioner, and said they would be right back to install it. 8 months later and after repeated visits to their office (which was always closed even during work hours) and many phone calls never returned, we ended up going with another company. Thank goodness we only paid for the furnace and not for the air conditioner as well!
