Kellam Mechanical continues to be the best! Just had my fall heating system maintenance completed. My tech was very courteous and professional. He arrived on time with a smile on his face. He took time to ask questions about my heating system performance, to explain the fall maintenance process, and to answer my questions. During the service, Shawn identified a problem with my downstairs system. He quickly initiated the correct actions that resolved the problem and returned my heating unit to full strength. Well done! Just had a water heater replaced. Attic installation. Extremely professional job. Neat and clean. Great company.
