My wife already gave a review on Facebook but that was when they first installed the new system in March. We love it. We told them what we were looking for and some issues we had with our old system and they fixed them all. Could not be more pleased. Now that we have had the system for a while and had cold and hot temperatures, I can attest to how good it really is. Quiet, Quiet and more Quiet and the distribution is equal throughout the house, which we never had before. No hot spots, no cold spots and you really can't tell the system is on or off. Awesome!! We chose the American Standard Platinum 20 variable speed system with two speed gas furnace and I would highly recommend it. I also highly recommend Tri-County A/C & Heating. Great folks and we will continue to do business with them in the future.!
