The technicians that come out are excellent. I've been using Glendale for a number of years, and they are so much better than the company I had before them. I have a maintenance contract so if I have a problem like my furnace won't go on, they get out here as soon as they can, even on the weekends. I think they really try to do a good job, and compared to past experiences their technicians are highly trained. I think it helps that the owner of their company is local.
