I had an complete HVAC change out by Buzzell around 3 years ago (see my prior review). My review remains top notch and is now confirmed. The Tech Serviceman was top notch (Arron) and knew what he was talking about (I've got about 35 years of experience both running and teaching how electrical power plants run, including A/C). I thought I had it diagnosed (a short that was causing the compressor to shutdown/restart) but Arron did a little bit of troubleshooting and determined in was actually a Freon leak (not a short). The Buzzell warranty was for 2 years labor and (from Reem) 10 year parts. Now this is where a grey area occurs. The Freon leak was from a part (covered) but, is the actual Freon also considered a "part". I talked to Mark (the supervisor/manager) who was a major part of my original review. He told me that Reem does normally consider the Freon as a warranty part. However, he offered a discount on the Freon which was probably not much over cost. From my experience (including initial offered prices) I would not hesitate to recommend Buzzell. They have great techs (yeah, Aaron, I mean you) and great management (Mark, if the head gets bigger is going to bust). The guys from Buzzell are all just "hired help". But people can be nasty or they can be nice. With Buzzell, you can want to do business with them again. I like Mark, Aaron and the other people that have come to my house. I think their prices are fair and Mark is something exceptional (again, see my previous review). I am not a Pollyanna. I'm relatively old (65), a Vietnam Era Veteran (married to a Vietnamese). My reviews are scarce (on anything, anywhere). It takes a lot for me to say anything. In fact I'm kind of a negative person. However, this Buzzell review has not changed in 3 years. If it does, I'll let you know.
