About Heating & Air Conditioning
Heating & Air Conditioning has operated in Greensboro for more than two decades, delivering heating and cooling solutions to residents across the Piedmont Triad region. The company, led by Donald Hamm, maintains an A+ rating with the Better Business Bureau and holds state licensing for HVAC installation and repair. With 12 verified customer reviews generating a 3.6-star average, the contractor serves Greensboro, Winston-Salem, High Point, and surrounding communities including Jamestown and Burlington.
The company distinguishes itself through responsive emergency service and transparent pricing on equipment replacements. Donald Hamm and his crew have built a reputation for same-day arrivals during heat waves and holiday weekend emergencies when systems fail unexpectedly. The team handles both routine maintenance and complex system replacements, including heat pump diagnostics and new AC unit installations. Customer reviews frequently mention fair pricing and straightforward explanations of repair options before work begins.
Recent customer experiences reveal a divided service record. Connie Johnson praised the team for arriving within 48 hours of her Saturday call and completing a two-unit installation by early afternoon the following day. However, multiple reviewers including Darrin Mcdowell and Melissa Johnston reported missed appointments and unresponsive communication after receiving confirmations. These contrasting experiences suggest service quality may vary depending on workload and scheduling factors.
