The Owner, Tim, was very nice to deal with. The installers were exceptional, clean, very nice, communicated very well (in person, via text, via phone calls). I am a hands on guy and very picky about the installation and where all the piping, duct work, electrical, and machines were to be placed and run through my home. Whenever I questioned something or asked if something could be routed in another way, they came up with a solution and there was never an argument. I saw no skimping on anything in the installation and they always used the best quality parts and they had the viewpoint that they wanted to do the work so that there wouldn't be any problems with the installation over the years to come. My system is a Trane high tech variable speed system and the installers knew what they were doing and how to install it correctly. The system is unbelievably quiet and smooth. The only complaint is that the install (for 2 systems and a lot of duct work changes) was anticipated to be 4 to 5 days and it took 7 days, but I was OK with that as long as it was being done correctly and meticulously. No additional charges or surprises.
