Baystate Energy Services

Baystate Energy Services is an HVAC company in Plymouth, and a recent customer says that when the air conditioning broke down on the evening of a holiday weekend, Jay and his son came to the home in Plymouth very quickly, diagnosed the issue and had the system running again. A recent customer says Jay diagnosed the problem as a switch in the attic and climbed up through a tiny, difficult entrance to fix it. A recent reviewer says Jason spent his Friday night diagnosing an AC issue nobody could figure out, and that his teammate Pete then replaced the compressor and crawled through an attic to trace the lines. A condo resident says Jason stopped by at 10:00pm on a Saturday and worked through the problem, including a phone call with Mitsubishi tech support. A recent customer says Jay fixed a mini split that was still under warranty after ordering the parts. The company's website describes a Plymouth home-comfort company selling heat pumps, furnaces and air conditioning alongside residential electrical and plumbing work, and says it has served the South Shore since 1998. A recent customer says Jay did a full house heat pump install. A recent reviewer with an antique home says Jay and his crew treated it with respect through the installation. In a 2025 review, a customer said that after quotes of $10,000+ from other companies, Jay told them about Mass Save, helped them through the process, and they ended up with an entire new system for free, installed in a day's work. A 2025 customer said Jay and his team installed a whole home heat pump system with ductless mini splits and a ducted system for the second floor in three days. A 2025 reviewer said Jason came back hours later, after a town-wide power outage ended, to finish getting their AC running. In a 2024 Google review, a customer said Jay and his crew converted an old oil heating system to heat pumps with a new water heater, arriving early in the morning and leaving late at night to get the job done, and later converted an oven from natural gas to liquid propane and installed a new gas line. A 2026 customer whose heat was not working said Jason came by that night, his team came back on Saturday, and they sopped up a flooded basement and swept up a mess they had nothing to do with. One 2024 Thumbtack customer gave one star and wrote that the job was "Cancelled morning of."
