A recent customer said DNA Plumbing and Heating was dispatched through a home warranty provider, HomeServe, to replace a water heater, and that the job from first phone call to install was handled within a few hours. That customer said Dewayne and the crew were prompt, courteous and communicative. The company's website lists drain cleaning and unclogging, drain camera inspections, water and sewer line repair, installation and excavation, water heater repairs, emergency plumbing, and water and fire mitigation, and names Meriden, Middletown, Wallingford, Southington, Cheshire and Waterbury as its service area. A 2022 customer said the company changed out an on-demand gas heat and hot water unit, and that Dewayne, the owner, answered his phone on a Sunday to walk them through fixing a minor problem, which the customer said was not due to his work. A 2025 reviewer at a hotel said the company installed 4 boilers with very little shut-off time. A 2025 customer said they came in and fixed the plumbing quickly.

DNA Plumbing and Heating was dispatched to complete a water heater replacement through my home warranty provider (HomeServe). Dewayne and the crew were prompt, courteous, and communicative. The entire process, from initial phone call to water heater install, was seamless and handled within a few hours. Very grateful to the team and won't hesitate to call them with future HVAC needs!
After struggling with a situation at home and not getting any answers this team was there quickly and with the expertise and honesty I was looking for. Would highly recommend.
Dewayne and his crew did a great job! I highly recommend 🫡
