Homeowners who hired Kato in 2026 consistently describe prompt, on-time visits and clear communication about the work being done. Reviewers point to specific jobs: a shower valve leak that had caused ceiling water damage, repaired with minimal drywall cutaways and protected flooring; a water heater installation that corrected an out-of-code condition and included an oil-heating emissions check; a kitchen drain and dishwasher connection fix offered with a free estimate; a backflow inverter installed to feed an irrigation system; and a two-day assist on a mini-split heating project completed around a customer's delivery delay. Every review on file is five stars, and the company's overall Google rating stands at 5.0 from 17 ratings. Kato Plumbing and Heating offers free estimates and states it provides plumbing, heating, boiler, water heater, and drain services throughout Southern New Hampshire. The reviews on file span a variety of job types rather than repeat visits from the same few customers, and each names Aaron directly as the technician doing the work. Kato Plumbing and Heating is a strong option for plumbing and heating work in the Manchester, NH area — homeowners consistently cite prompt, careful, well-communicated service from a state-licensed plumber, and the free-estimate offer makes it easy to get a read on a job before committing.
