Very pleasant at first...alarms should have gone off earlier, sent unlicensed installers and was never on the job himself.His worker bad talked him and one worker was bragging about his time in prison. The job was horrible! Had crossed and compressed soft ductwork re-routed. severe dead zones with no supplied air to ducts. To top it all, he demanded more money! Brought in a second HVAC company to figure out his mess $$$$$. Run from this guy!
