Hartford Mechanical

4.9(100)✓ Google-verified

Julio at Hartford Mechanical consistently arrives on time, diagnoses problems clearly, and solves them right the first time. His approach combines attentiveness to detail, transparency about what needs doing, and respect for customers' homes (cleaning up after sewer work, sourcing parts instead of pushing replacement). Most reviewers praise his knowledge and calm professionalism across emergency heating, water heater repair, and drain clearing. One reviewer noted prices are steep, though the quality and reliability justify the cost for most. No major gaps or service failures appear in the sample.

Delponte Plumbing & Heating

4.9(709)✓ Google-verifiedPublishes prices

Delponte staff solve problems methodically, explain what they find, and leave no mess. Named technicians like Mason, Evan, Landon, Steve, and Derrick appear across reviews handling everything from spigot replacement to mystery leaks and boiler install, praised for patience and knowledge. A three-year customer calls them "professional, timely, fair, organized" and others note quick Monday-morning dispatch even after a holiday weekend. Monthly membership starts at $29.95; one reviewer remarked the emergency response on a heat wave holiday was "expensive but given the response... no one was complaining." Service membership and proactive follow-up stand out. Charisse and Steve signed one customer into their HVAC maintenance program on the first call; Gabe, Dom, and Brian kept a boiler install "spotless throughout" and answered every question. Staff proactively fixed a secondary issue one household hadn't asked for, and another technician rang the doorbell because he'd been told the customer had questions. After-hours contacts get next-day 8 AM slots. The roster includes Mason Candler, Derrick Domina, Joel, Carson, and Landon, each cited for specific strengths.
