Williams Energy

Williams Energy is a heating and cooling company, and one recent customer was able to schedule an AC tech on a 100-degree day and said Kevin took the time to troubleshoot the problem and figure it out. The company lists a service area running from Braintree, Quincy and Weymouth to Plymouth, Carver and Middleboro, and says it has been in business 107 years. It holds 4.8 stars from 316 Google ratings, and its BBB grade is A+. A recent customer who bought a house two years earlier wrote that Williams did all of its electrical and plumbing updating, then responded quickly that winter to a leaking oil tank and a frozen broken pipe, with minimal damage. A customer of almost two decades wrote that the techs price a job out on the spot, and closed with thanks to Ian. In a 2026 review, a customer said Williams replaced a 50-year-old boiler and oil tank with an Energy Kinetics unit and a double-walled tank, and cleaned up afterward. A 2026 customer living in Florida wrote that their oil drum ran out on a Sunday during the coldest weekend of the year, that their service company of 40 years would not help until Monday, and that Williams took care of them even though they were not clients; that 2026 customer thanked Gavin and his team. A 2026 customer with a service contract wrote that they replaced an ailing humidifier, repaired bad wiring within the heating system and left the work area spotless. In a 2025 review, a customer wrote that others had written their boiler off as a lost cause and advised replacing the entire system. That 2025 customer said technician Shaun went over all the previous work and was able to identify and correct the issue. In a 2024 review, a customer whose boiler a national company had tagged as unusable said a Williams technician came that evening, made a few tweaks and got it running enough to take the chill off; that 2024 customer said the estimate in hand the next day was half the national company's price. A 2025 customer said Williams installed central air and splits in a house with a challenging room layout, hid the pipes, kept the furnace for backup heat and took care of the state rebates. A 2025 reviewer, a realtor, wrote that a seller's vacant home in Hingham had dropped to the mid-40s inside and that Williams had someone at the house within 2 hours. A 2022 customer described a single-zone ductless mini-split install in which Dylan and Ian arrived on time, and said Mike Williams called in from vacation at the end of the day to check on how everything went. A 2025 customer who called for propane delivery wrote that after being told 5-7 business days and then 7-10, nothing had been delivered when they posted, and that it took multiple calls to get someone on the line. A 2025 reviewer accused the company of fraud, writing that it charged 500 dollars for 10 minutes of work, never said what it would cost before starting, and used card information given a year earlier to charge them without permission. A 2022 customer wrote that the scheduling, customer support and techs were unhelpful, and that after signing a contract for at least a year they could not wait to leave the company.
