Charleston’s Local Family Built Heating & Air Business

AGL Services has consistently been an excellent repair service, with strong professionalism and technical expertise. On every job they have done for me they have exceeded my expectations, and their repairs last. I appreciate the peace of mind.

Been using AGL for the past 8+ years. They have been incredible to work with. They have performed a wide variety of services ranging from a simple repair to an extremely detailed full system replacement as well as ductwork. Will always use this company. All techs, office employees and the owner are extremely professional.

We love these guys. During our regular maintenance, we mentioned that our heating unit was louder than usual. Sean immediately diagnosed the problem. He and Steven returned 2 days later and replaced the "draft motor." Problem solved. They were punctual on both occasions and super friendly and professional. They know their stuff! And it's a plus that they're dog lovers! Highly recommend.

AGL is an amazing company! I can't speak highly enough of them. All of their employees are very educated, helpful, professional and prompt. Steven C was of great assistance in helping fix my evaporator coil and getting my AC to work. He was also able to help my neighbors with a similar issue. I will always use AGL from now on!

AGL has been a fabulous company for my heating and air. They were able to fix my old system and keep it working for 2 years until I had to replace the unit. The new system they put in has been wonderful. They come and service it twice a year. They are always friendly, courteous, and helpful. I trust them and highly recommend them to my friends and family.

Great company! I called as a new customer - they fit me in that day. Becca, the customer service rep was friendly and polite on the phone. Shawn, the technician was great - professional, on time, and above all else honest. They have a service package that is a great value! I am very happy that I am now considered a customer of AGL Services. I highly recommend them.

AGL has been a great service from day 1 with a full install of a new unit & all ducts replaced. They service 2x a year & keep my HVAC working great. Recently had an issue with my system not working during the hottest month. They came out the same day of call & fixed the issue. I would highly recommend using AGL Services!
