I have been wanting to review a project like this for way to long, and I am excited and ashamed of myself it has taken this long to do so. I have always heard how expensive a complete rip and replace of an old A/C - Furnace System was. I live in McKinney TX and it can and will get both HOT (9 months of the year) and COLD (3 months of the year). My home was built in 1998 and I took ownership as the 2nd owner in 2006. Simple 2 story, 3,100 Sq. FT 4 BR (all upstairs) brick home. From the 1st day of ownership I noticed a little white fluffy floating armada from a Cotton Wood Tree behind my home in a neighbor’s yard zeroing in on my pair of units outside and the battle was on. The fight has been brutal, and I have lost 3 units, all have been the same upstairs machine. I have been limping by the last 2 summers with portable air conditioners in each bedroom and the time had come to fix my old and tired install. I over researched all the options available on the web (price, reviews, products & service) etc. until my head hurt. I asked a few to come out and Green Leaf Air was by far the only company that just felt right. From the consultant that came by to inspect my home, to the owner and project foreman who have OVER communicated throughout the entire process to the ladies in the office who have called and re-called to confirm dates and times along the way. I purchased 2 Carrier 4 Ton 16 Seer complete units. They were installed over 2 days to ensure we had air available to us always. Each install took about 8 hours, and the attention to detail by the crew ensuring carpet was covered and walls and doors looked the same when they left was appreciated. I am 100% satisfied with the final installation. Every appointment was kept and the arrival time for each appointment was meet or exceeded. Thank you for the time, effort and assistance along the way Green Leaf Air. I will recommend you without hesitation.
