Mac's Plumbing and Heating INC

Mac's Plumbing and Heating INC is a plumbing and heating contractor based in Kingston, on Massachusetts' South Shore, offering residential and commercial work such as water heater installation and repair and thermostat service. The company holds a 4.9-star Google rating from 36 reviews and 5.0-star ratings from 13 reviews each on Angi and HomeAdvisor. Reviewers across all three platforms consistently name Donald, also called Donny or Mac, as the technician doing the hands-on work, with Jennifer handling the office. In a September 2026 review, a customer described the company resolving two after-hours plumbing emergencies, procuring the needed parts quickly and completing both repairs the same night. An August 2026 review credits Donald with tracking down a hard-to-find source of water entering a basement and fixing it on the spot, and a June 2026 review describes the company responding the same day with a reasonable estimate after other plumbers left the customer with only high quotes and unanswered calls. Earlier reviews dating back to 2022 describe similar work and a consistently clean, professional approach: fixing a leaking dishwasher connection and installing a sediment filter, repiping a house and updating its cast iron plumbing, and a customer who called the work environment very neat with pricing spot on. Several reviewers from that period say Donald has serviced their home multiple times at fair, competitive prices and is their first call for plumbing work. The company's own website lists a plumbing license number, MP# 17423; Angi and HomeAdvisor list a different trade license number, 32068, for the business. For a homeowner on the South Shore who needs a plumber for anything from a routine repair to an after-hours emergency, Mac's Plumbing and Heating has a consistent, multi-platform track record of customers who say they would call again.
