Kris Johnson Electrical Mechanical is a Hingham outfit that's grown into heat-pump and ductwork installs as much as electrical work over two decades — the BBB, which does not accredit it but grades it A+, records the company incorporated in 2005 under president Kris T. Johnson. The work reviewers describe is detailed and largely positive. In a 2025 review, a customer had two Bosch heat pumps installed with new zoning and redesigned ductwork in an antique home, and praised the crew for working around the household's schedule and preferences; a 2024 review described technicians who worked diligently for days, cleaned up daily, and walked the homeowner through the finished system. Further back, in a 2021 review, someone called the crew "very skilled electricians" who did a first-class job at a fair price. Two 2025 reviews raise a different issue — both describe a driver of a company pickup truck or van behaving aggressively on the road (obscene gestures, tailgating), and one says the office brushed off the complaint when called. In a 2022 review, a customer said the company came out twice without resolving the problem; in a 2021 review, someone described an estimate process that stalled when they wanted to discuss details by phone and were told the owner prefers email. The BBB's A+ grade sits alongside those driver complaints, which is worth knowing going in — and worth asking directly how they'd handle a follow-up call if something needs a second visit. For a straightforward heat pump or electrical install, though, the written record is mostly people happy with the finished work.
Working with Kris Johnson and his team is truly a pleasure. They are efficient, thorough, knowledgable and most importantly - courteous and kind. Their customer service is OUTSTANDING and they ensure the job is done right - everytime. Shout out to Dan and Mike who recently worked so hard identifying and fixing a complex HVAC issue in record time. Thank you of course to Kris himself for being communicative and helpful. Always a pleasure working with these guys.
Was referred to Kris Johnson through Bosch's website when inquiring on a heat pump. They not only provided the best price but were able to work within the timeline needed to keep our project going. After installation, we did have an issue with the heat pump which they were very reactive to getting resolved under the warranty.
Had a similiar encounter like peter parkman. Driver in one of their white pickup trucks seems to have anger problems on the road and likes to give obscene gestures to other drivers. Called number on side of truck and person who answered seemed to brush off the problem
I haven’t worked with professionally, so I can’t comment on their work. However, this morning I was cut off by one of their vans. The driver cut in front of me as we approached a red light. Seems he was in the wrong lane. I honked, thinking he couldn’t see me, and he flipped me off and yelled obscenities. Once we passed the light, he proceeded to drive about 20mph for several miles despite the speed limit being 35-45mph. The slow down caused me to be late, and likely wasted company time. While I can’t comment on their electrical work, I would never hire a team this petty or that conducts themselves in such an unsafe manner. I can only imagine how they act on a job if things don’t go smoothly.
Couldn’t be more pleased with Kris’s team (Bill, Jimmy, and Mike)! They worked around our schedule and timeline, respected the cleanliness of our home, and adapted the system to work with our antique home (and my preferences!). They installed two Bosch heat pumps, added zoning, and redesigned all new ducting. Very thorough, we’re pleased with the outcomes and will definitely be using for future HVAC projects!
