Claim This BusinessAlexander Heating & Cooling has served Charleston, SC since 2015 with 406 five-star reviews reflecting consistent excellence. The company operates Monday through Friday from 8 AM to 8 PM, with Saturday and Sunday availability from 8 AM to 6 PM. Chris and his team provide residential HVAC installation, repair, and maintenance across downtown Charleston, Mount Pleasant, North Charleston, and the surrounding Lowcountry communities.
What distinguishes Alexander Heating & Cooling is their commitment to transparent communication and thorough follow-through. Chris personally photographs completed work and shares images with homeowners to document repairs, a practice one reviewer credited for resolving a warranty dispute. The company maintains same-day availability for emergency calls, stocks common replacement parts on their service vehicles, and offers complimentary annual maintenance for customers who purchased systems from them. Their service range extends beyond standard HVAC to include pool heaters, hood vents, and water heaters, making them a versatile resource for whole-home comfort.
Reviewers consistently highlight specific technicians and scenarios that demonstrate their reliability. When Amanda Virostek's heater failed in mid-February, Chris fit her in the same day, explained the issue clearly, provided a fair upfront quote, and completed the repair using a part already on his truck. Joey's review describes a full system replacement completed faster than expected at a fair price, while Christy Bartosic notes Chris went above and beyond by clarifying a warranty company's assessment and sending her a photo of her handler after the work was done.
All 406 reviews award five stars, with Chris named in every reviewed testimonial. Customers repeatedly mention same-day emergency service, fair upfront pricing, and Chris photographing completed work for transparency. Multiple reviewers describe the team as honest, reliable, and experts in their craft.
