These guys came out and did a complete install at our new house...the place had no duct work whatsoever, having never had heating or air conditioning prior to our moving in...they came out and gave me an estimate (which was thousands of dollars less than some of the other local contractors I had out), I called them back on a Tuesday and asked if they could be done by that Friday...and they were. I am an Electrician by trade, and I have been on many job sites over the years, I know a clean install when I see one...and I can tell you that these guys did a perfect install...nice and clean...very professional. If youre looking for someone to take care of you on your HVAC, install or otherwise, these guys are good...and they are not out to retire off of just your job - they are not gouging people on pricing like so many others are - I like them, and if youre reading this review, I recommend them to you.You can pay more, sure, but youre not going to get more.... thats a fact.So, call em..check em out.......Mike & SueSan Diego - East County
