We knew we needed to replace our close to 20 year old unit and after reading reviews on AC4Life decided to give them a try. We had done research on what we thought we needed and when Charlie came to assess our needs, he agreed with our conclusions. He didn't give a hard sell on additional products/services, but rather offered them for consideration. We did end up spending more than we had originally planned, but that was our choice due to deciding that some upgrades were worth the investment. The team showed up as scheduled and all were professional, courteous and thorough. We couldn't be happier with this company and would highly recommend them to anyone. They follow up with phone calls to make sure everything went okay and that we are satisfied. While they may not be the cheapest, my feeling is you get what you pay for and they are worth spending a little more.
