Alexander Heating & Cooling

Alexander Heating & Cooling operates as a full-service HVAC contractor serving Charleston, South Carolina, and surrounding communities. With a perfect 5-star rating across 430 customer reviews, the company has established itself as a trusted name in residential heating and cooling solutions. The business maintains extended service hours seven days a week, with weekday operations running from 8 AM to 8 PM and weekend availability from 8 AM to 6 PM, ensuring accessibility for homeowners managing urgent climate control needs.

What distinguishes Alexander Heating & Cooling from competing contractors stems from their diagnostic approach and customer communication. Multiple reviewers note that previous companies provided conflicting diagnoses before Alexander's team correctly identified the underlying issue. The company emphasizes transparent pricing, with reviewer Jenna Rae Yates specifically mentioning they beat competitor estimates by thousands of dollars while only recommending repairs that were actually necessary. This honest assessment style resonates particularly with single homeowners who often feel vulnerable to upselling tactics.

Customer experiences highlight specific technicians who deliver exceptional service. Technician Matt earned praise for same-day emergency response during an AC failure, taking time to explain the diagnosis clearly. Reviewer Bob Renna described a seamless new 2-stage HVAC installation handled by Chris, who arrived on time, worked efficiently, and left the home clean. Joey noted Chris and the team have serviced their property for years without a single bad experience, recently completing a full system replacement faster than expected at a fair price.
