After reviewing 8-10 quotes, I picked Air Makers Inc to replace the AC and Furnace of my house. I am absolutely pleased to do business with them due to numerous reasons. (1) - Customer Service. (2) - Product/Industry knowledge. (3) - Honesty. (4) - Quality Workmanship. (5) - After sales support. I got my Carrier Infinity system installed in Oct 2012. I was informed of all the government rebates available at the time. I inquired about multiple system combinations to get the best value. All questions were answered to the point with professionalism. Shabnam is an absolutely outstanding person to deal with. To date, I have had 2 very minor issues that were taken care of by Air Makers Inc right away. I have recommended this company to my friends who have also had positive things to say about them. I strongly recommend Air Makers Inc.
