Six trucks and ten workers in the driveway by 8:00 a.m. on day one, the job substantially done by day three — that is how a June 2026 Google reviewer described an installation by Northern Comfort Heating & Air Conditioning, a Bridgewater HVAC company whose website says it is family-owned, with Eric Costa named as co-owner and service manager. That customer also credited Eric with daily updates, guidance on the Mass Save program and a garage left cleaner than before. Recent Google reviews lean on Eric's availability and on straight talk. In a May 2026 review, a furnace customer said the company told them the older system could still run for a while before recommending replacement, and that honesty is why they went ahead with a new system. Another May 2026 reviewer described two mini splits installed at an older two-floor cape for parents in their late eighties, including showing them how to use the remote. The complaints are about money and disclosure. In a September 2025 Google review, a customer said it took about a week to get a technician out during a July heat wave, the $20,000 replacement quote was never itemized despite repeated requests, and a $300 diagnostic bill arrived without the fee having been disclosed. In a February 2026 review, a property manager said a no-heat call was billed at $800 an hour, $1,600 plus a $300 diagnosis fee, over their objection. The Massachusetts HVAC licence held by Eric J Costa is active, and the BBB lists the company as an accredited A+ business. Google shows 4.2 stars from 10 ratings and Thumbtack 5.0 from 5; the website gives its history as both over 50 and over 20 years.
“Then Aunt Theckla pulled out her furnace cards & called Northern Comfort.”
I’m not sure if there is enough space in this text box to summarize all the outstanding things I have to say about Eric and the team!! From the very beginning, we knew we were in the very best of hands. Eric was kind, approachable, patient with all our questions, and extremely thorough with his explanation of each of the steps of our project - up to and including walking us through best practices for the Mass Save program. Eric was extremely responsive- always a text or a call away - providing proactive updates and recaps every day. My biggest take away from our project was how efficient and clean everything was. Day 1, by 8:00am sharp, I had 6 trucks and 10 guys in my driveway! By day 3, they had substantially completed the job. And by day 4, Eric was showing me how to use my t-stat. All the while not so much as a spec of sawdust was left behind. In fact, my wife was excited (nagging me) that our garage was exponentially cleaner after the project than before!! If possible, I’d give Eric 10 stars. Came in as a vendor and left as a friend; I could not recommend him and the team highly enough!!
Northern Comfort serviced my AC this past season. I can’t speak highly enough about them , the service tech was on time and very courteous. The job was finished on time for a reasonable price. Highly recommend
Unreal service. Company is top notch Eric is one of the easiest guys to talk to and understand. His cell phone is always on and he’s always available. 10/10
Eric, Sandy and the team are fantastic!
Put in 2 mini splits at my elderly parents house last year and was a smooth transition! The house is an older cape with 2 floors. The company took the time to show them how to use the remote too! Which wasn’t easy for my parents as they are in their late eighties! Several phone calls and visits and they are very happy with their system! I would highly recommend this company for any heating/cooling needs you have! Saves money in the heating months to !!
