Gary came out and completed an energy audit of my sister's home in Phoenix after a new AC system was installed. We chose to have insulation blown in, add another supply duct in the kitchen and replace the old electrostatic filter with a standard fiberglass 20x30 ceiling return. The crew showed up pretty much on time and got to work. It was a 110 degree day. They worked very hard and nearly completed everything in one day. We discovered an issue with the installation that I will not go into detail but Gary had no problems making it right. Gary even went over the top and completed the demo of the electrostatic filter closet and intake. That alone was almost another half days work for him. I have no problem recommending Eco Systems and plan to use them again if the need arises. Good work Gary and team...
