What customers said about a/c system repair
Bama Air Systems Mechanical Contr…Brandon Busby usually does our work. He’s on time and always very courteous and professional. He does a thorough job and make sure everything is working properly before he leaves and never seems to grow tired of me watching him. Do what he does. His patience is quite remarkable. I would highly recommend him and Bama Heating And Air.
High Caliber MechanicalThey did a great job on both of our houses. I give friends that ask who does my service the company’s name and phone number.
All Around Heating & CoolingBig Shout out to Kevin and Jack for their fantastic service they did this afternoon…quick to come out, fix the AC, courteous, honesty, kindness…great qualities and I will get them to come out again if needed. Check them out next time you need your AC or heating fixed or get on a maintenance program! Thankful for them!
Proper Climate, IncThese guys are awesome! They didn't recommend just replacing the unit, they actually diagnosed the issue and had us back up and cooling in no time! 10/10 will use them again!
Cullman Heating & Air - HVAC Cont…Amazing service, I was able to get my AC repaired same day. Alex quickly identified the problem (locked fan motor) and showed he was extremely knowledgeable when explaining what he was doing to fix it. Highly recommend!
Bama Air Systems Mechanical Contr…They came within a few hours of me calling and the technician knew what he was doing and fixed our AC. I recommend this company to anyone.
