Reliable Heating and Air, LLC

Reliable Heating and Air, LLC has served Summerville and surrounding South Carolina communities with round-the-clock HVAC expertise for over a decade. Holding a 4.9-star rating across 162 verified customer reviews, this contractor operates 24 hours daily, 7 days a week, ensuring residents never face a heating or cooling emergency alone. The company maintains full licensing and insurance, serving Summerville, Charleston, North Charleston, and the greater Dorchester County region with both residential and light commercial capabilities.

What distinguishes Reliable Heating and Air from regional competitors is their in-house sheet metal fabrication shop, a capability most independent HVAC contractors outsource entirely. Their service menu includes commercial refrigeration and specialized indoor air quality solutions such as REME HALO air purification systems, energy audits, and blower door testing to identify duct leakage. The company offers financing options, senior and military discounts, and preventive maintenance service agreements designed to extend equipment lifespan and reduce monthly utility costs.

Customer reviews consistently highlight technician Chris as the face of the company, with multiple homeowners noting he arrived same-day when called and explained every diagnostic step in plain language. One reviewer described how Chris arrived early to prep for a full system installation and stayed past business hours to ensure the new equipment operated perfectly. Another homeowner recounted Chris clearing ice from a failed heater, walking through each repair step, and triple-checking functionality before leaving, all without suggesting unnecessary upsells.
