K & B Plumbing is a plumbing and HVAC shop, and one customer said Keith came the day they called with an AC problem, was on time and thorough, and has since been retained to take care of their heating and AC. The company's website says it started in 2024 with five technicians and serves Western Massachusetts homeowners, naming Springfield, Chicopee, Holyoke, Agawam, East Longmeadow and Palmer. Keith Bilton's Massachusetts plumber license, number 17691-PL-M, is active on the state registry. On Google it holds a 4.9-star average from 69 ratings. One customer replaced a central air system installed 17 years earlier in an older home and said the job was mishap free; they took time to walk that customer around and show what they did and how to operate it. A customer who woke up to a slight leak on a fridge water line said the company came out the same day, sooner than the time estimate first given, and Seth replaced everything that needed to be replaced. A customer whose 12-year-old hot water tank was leaking at the bottom said owner Keith Bilton quoted a new propane hot water tank, pipes and a bigger vent pipe for the chimney at a reasonable price, then got the tank and everything needed for the job. Griffin diagnosed the problem and George installed a new pump, one customer wrote. A customer said KB removed an old water heater and ran new pex water line under a crawlspace. A 2026 customer said Keith changed out a failed boiler and a horizontal oil tank perched on a ledge in the basement, and wrote that Keith "arrived on schedule, finished on schedule." A 2026 customer who discovered a leak in the basement said Griffin arrived earlier than expected, gave clear, honest quotes for each scenario, and had the toilet fixed and the house dry the same day. A 2026 customer moving from an oil furnace to gas heating with added central AC said KB came in with his team and took care of everything. A 2026 customer said Keith came back to repair something and fix some work and did not charge for either. A 2026 customer said Keith came out the very next day to replace a washing machine valve and hook up a new hose.
