D&A Heating & Cooling

D&A Heating & Cooling has earned a 4.9-star average from 412 reviews, making it one of the most-reviewed and highest-rated HVAC contractors in Prince Georges County. Based in Hyattsville, the company serves homeowners throughout College Park, Greenbelt, and Beltsville. Monday through Friday, their crew handles everything from routine maintenance to full system replacements, leaving Saturday and Sunday for emergency callbacks when needed.

Customer feedback reveals a contractor that earns trust through speed and transparency. Multiple reviewers describe technicians explaining what caused their problem and what steps prevent future breakdowns, rather than simply collecting payment and leaving. The company has handled furnace replacements, humidifier upgrades with Aprilaire equipment, and damaged return ducts in attics. One reviewer specifically noted they replaced a broken humidifier and reported noticing improved comfort throughout the house within a single day of installation.

Chandra Sahajwalla called after one thermostat malfunctioned months after installation, and a technician arrived within 24 hours to resolve it. When Ilze Mohseni reported a furnace failure on an evening before temperatures dropped, D&A scheduled a same-day appointment and sent a knowledgeable technician who explained exactly what caused the failure. Cheyenne Mattu received a diagnosis and working heat in about 30 minutes after an emergency call, with both technicians described as friendly and professional throughout the visit.
