Gray Co

Gray Co is a plumbing, heating, air conditioning and geothermal contractor that Michael Gray says he founded in 2002; its site places the office in Billerica and the BBB lists 26 employees. A Bedford neighbor wrote on Nextdoor in June 2026 that the company is very busy but fits them in, recommending Mike. In a December 2022 Google review, a customer said their boiler died five days before Christmas and Gray Co removed it and installed a new system before the holidays. In an October 2021 review, a customer said Mike came the same day they called for a furnace replacement, quoted it the next day, and the crew installed it that Thursday and cleaned up. A December 2022 reviewer called the pricing not the cheapest and not the most expensive. In a February 2024 Google review, a customer said they kept receiving bills they had already paid and could not reach anyone to resolve it, and an August 2025 reviewer said a company truck driver tailgated and yelled at them on the highway. Gray Co holds 4.1 stars from 13 Google ratings and an A+ BBB grade. Michael Gray's Massachusetts plumber license, #12426-PL-M, is active on the state registry.
