The old unit left in the…read morecondo was horrible and there were so many things wrong that we didn't realize until it finally stopped working. John, James and Kyle went above and beyond the original scope of the work to do a proper install. Needless to say we now have an amazing unit done correctly. He and his crew are meticulous, neat (cleanup looks like no one was working there) and his recommendations were spot on. A real pleasure to have found him. Hopefully I won't need his services in the future but if I do he'll be my first call. Thanks again.

I understand that this is a very busy season but not a call or email for just an appointment is not good. I do not understand why some companies even offer the option to fill in for a request on their web site. I filled out three other requests and with a day they provided me with an appointment. It's a shame because I liked the puppy sitting with the owner! Update on 07/1 I called again and this time I spoke with Christian who set up an appointment for 7/03 between 1-3pm.
