AGL Heating & Air

AGL Heating & Air has served Johns Island and the greater Charleston area since 2004, building a reputation as a family-owned contractor with 881 five-star reviews. The company holds proper licensing and serves communities across the region, including Mount Pleasant, Daniel Island, West Ashley, and the barrier islands such as Folly Beach, Isle of Palms, and Kiawah Island. Their round-the-clock availability during the week and weekend hours reflect a commitment to responding when residents need climate control help most.

What distinguishes AGL from other regional contractors is their dual focus on premium equipment partnerships and community responsibility. As a Trane dealer with access to WaterFurnace geothermal systems, they install some of the most efficient heating and cooling technology available. The company offers a 15% discount for first-time repair customers and donates a portion of all proceeds to charitable causes, reflecting values that extend beyond profit.

Local reviewers highlight specific technicians who resolved problems other companies could not. Stefan Kwasny credits Cory with both performing preventive maintenance and correcting multiple installation errors his builder had made. Mary Lib describes how Sean and Steven diagnosed a noisy heating unit and replaced the draft motor within two days, praising their punctuality and technical knowledge. Michael Jarmusik notes that estimator Shonn recommended a appropriately-sized system rather than upselling a more expensive unit, and that the installation team arrived on time and completed the job professionally.
