AGL Heating & Air

At AGL Heating & Air, we genuinely care about the comfort of the people we serve. We’re a local, family-owned and operated team, and since 2004, we’ve stayed true to our original goal of providing honest, high-quality heating and air conditioning service. Integrity is the foundation of everything we do, from new system installations and routine maintenance to equipment repairs. We serve coastal communities throughout the Greater Charleston Area, bringing dependable workmanship and a commitment to doing every job correctly and safely.

Our certified technicians have more than 100 years of combined experience in heating and ventilation installation, maintenance, and repair. We don’t take shortcuts or rely on inexpensive materials simply because they make a job easier. Instead, we use quality equipment and focus on work we can stand behind. We strive to offer competitive pricing along with honest, reliable, and skilled service. Whether we’re helping extend the life of a heating system, improve its efficiency, or address a repair, we take pride in giving each system the care it needs.

We also have more than a decade of experience providing geothermal heating and cooling systems in Charleston and surrounding communities. As a highly qualified provider of WaterFurnace geothermal products, we can assist with geothermal equipment repairs, routine maintenance, and complete systems. These systems use renewable geothermal energy from the ground around a property and may reduce energy use for heating, cooling, and hot water. We can also address a hot geothermal well with an evaporative cooling tower, which cools air through water evaporation. From conventional HVAC work to geothermal solutions, our goal is to provide thoughtful service grounded in honesty, quality, and care.
