Casteel Heating, Cooling, Plumbing & Electrical

Casteel Heating, Cooling, Plumbing & Electrical has served Marietta homeowners since 1998, building a reputation across Cobb County and the greater Atlanta metro including Roswell, Kennesaw, and Smyrna. The company holds state licensing for HVAC, plumbing, and electrical work, allowing homeowners to make one call for multiple trade needs. With 10,178 verified reviews yielding a 4.8-star average, Casteel operates around the clock seven days a week, a practical feature for a region where summer temperatures regularly exceed 90 degrees and system failures rarely wait for convenient timing.

What distinguishes Casteel is its multi-trade structure under one roof, a convenience that eliminates coordinating separate contractors for interrelated problems. Technicians such as Adam, who guided homeowners through new AC system selection with detailed capability explanations, and Cody, who conducted thorough inspections identifying issues invisible to standard home inspectors, reflect a diagnostic approach that positive reviewers consistently mention. The company provides written warranties on workmanship, though specific terms vary by service.

Customer stories from recent reviews illustrate real scenarios: Harv Hobson's two-AC replacement involved a full installation crew including Junior, Nick, and Mohammad completing the work in a single day with careful attention to cleanup. A reviewer named John arrived on January 24, 2026, demonstrating calm professionalism while diagnosing a complex concern over multiple hours. These named technician references suggest the company maintains experienced staff who build client relationships over repeat service calls.
