With all of the positive reviews I previously saw and still see for this company, perhaps I just had a one-off experience with them, but it was a truly terrible experience. I hired this company to replace my entire A/C unit, duct-work, etc. (everything but the furnace), costing a grand sum of a little under $9,000. The hope was that we would have a great new system that would last many years. Instead, the night following the new installation (this was back in August I believe, so it was very hot), I came home to find that the A/C unit in attic was leaking right through my roof. We were able to get the company to send people back out (it took several trips), though they were very resistant to taking responsibility for repairing the ceiling. Eventually after repeated attempts they agreed to bring out a contractor to fix everything. I was not too upset over the poor installation job, as these things can happen, but the subsequent struggle to get this company to fix the issues and damage caused by them was very frustrating. Since then, we have experienced several subsequent leaks in the attic, and have hired different A/C companies to come out and fix various problems with the initial installation (we did not trust this company to attempt to make these repairs after the bad experiences we have had so far and the fact the problems with the installation continued to rise. We also learned that the reason the A/C sounds so loud on our top floor is because this company did not install some component (a control valve or something) that is supposed to handle the additional pressure caused by only one floor being on versus all three. I debated leaving a bad review on Yelp, as I rarely ever do so, but now that our heater has kicked on for the first time since the installation, we have discussed yet another issue with hot air coming out of the top floor vents whenever lower floors are running, causing the top floor to get very hot and soon require the cool air to kick on and cool it down (causing a constant back and forth). We have spent over $1,000 since the original installation, which does not include the costs of this latest issue, plus ANOTHER leak we discovered a week ago. This is by far the poorest A/C installation job I have ever seen done on a house.
