"This was my second quote and this company is amazing. Quickly identified the issue, changed the motor, provided a filter and made sure everything was working on one trip within a few hours. The previous company (Air Pros, LLC) said it was unfixable and tried to sell me a new unit over $6k which was a huge scam. Don't go to those guys, work with this family owned honest business. Keep in mind HVAC repairs in many cases are not cheap, I own 3 houses and have paid several hundred or more when an HVAC is old and need repairs."

"He was on time first of all, no 4 hour window crap he said "I'll be there at 10.00" and he was there at that time. While he was repairing the furnace I asked him several questions about the unit which he answered in a polite, professional and friendly manner. He made several suggstions on what types of units gave the best and most reliable service and what he would charge to install them. My father is a HVAC tech so we called and asked for his estimate on the part and service and the price we got was for parts and service was 30% BELOW his estimate. This was an all around excellent experience, It's Aire Central all the way from now on !!"

"My husband and I have used Moncrief for nearly 30 years -- ever since we bought this house. The prior owner used Moncrief and recommended them. Over the years we have had this company perform all service/maintenance work on our HVAC system. They are not cheap, but they do good work and are very trustworthy.

"I?ve known Drue Lawrence and his family for years. He is one of the kindest, caring, and responsible guys I know. He treats people with the upmost respect and pays attention to the details. I?ve seen him first hand as a guy who shows up every time and is a hard worker with a heart of gold. I am so excited for him to be in our region as an excellent general manager for Varsity Zone HVAC but even more excited to have him back in ATL as a friend. I would highly recommend him and the team to anyone, he does a great job every single time."
