E. Dennis Heating, Cooling, Plumbing & Electrical

E. Dennis Heating, Cooling, Plumbing & Electrical has earned a 4.9-star rating across 5,154 reviews while serving Marietta and the greater Cobb County area. This full-spectrum contractor handles heating, cooling, plumbing, and electrical work from a single dispatch, meaning homeowners can call one number for multiple system failures. The company maintains 24/7 availability including weekends and holidays, positioning itself as the primary call when Marietta residents face sudden HVAC failures, burst pipes, or electrical emergencies.

What distinguishes E. Dennis from neighboring contractors is their multi-trade capability combined with same-day service on most calls. Unlike shops that sub out plumbing or electrical work, they field in-house technicians trained across all four disciplines, reducing callback delays and coordination headaches. Their review volume and consistent five-star feedback suggest a systematic approach to training technicians and managing customer expectations around timing and pricing.

Reviewers repeatedly name specific technicians who arrived on the same day during emergencies. Guillermo Lacasa handled a Saturday emergency water line repair that required melting sheared PVC from a brass fitting, completing the job in under two hours. Ian resolved a children's toilet clog by identifying a root cause rather than applying a temporary fix. James arrived on time for a toilet installation, cleaned the workspace thoroughly, and even helped the homeowner with groceries. These named encounters illustrate why the company maintains over five thousand reviews.
