• Had them come out for a routine gas boiler cleaning. Professional and polite. Easy to talk to and provided useful information for homeowner maintainence. Nick was great.

• I can't say enough great things about Coastal! After years of putting off having heat pumps installed, they have been amazing. They arrived with a full crew (while it was raining, then pouring) were prepared and completed my whole house (and it is no small house, they installed a ducted heat pump system upstairs and wall mounted units downstairs, in a very old house) in one day! They are fair with pricing and incredibly attentive to detail. If I could rate them more than 5, I would!

• We had a mini split system installed by coastal in Dec of 25. We recently turned the system on due to the hotter weather and WOW. It is an amazing system. There are 2 condensers outside running 6 wall units inside. 3 on the first, 2 on the second, and 1 on the 3rd floor. It was a massive amount of work and Coastal got it done in ONE day with 8 guys completing it. The entire crew Mike, Lisa, Nick, Dana, Alex, and everyone else were absolutely phenomenal. I would highly recommend Coastal Air Conditioning for your mini split system Sincerely Jay Quincy Ma.

• We used Coastal to install whole-home heat pumps and had a great customer experience. The team was highly responsive even before installation, answering all of our questions promptly and guiding us through each step of the process. Mike and Lisa were especially helpful and always available, making sure we felt supported and informed throughout. The installation team was professional, respectful of our home and the environment, and completed the entire system efficiently and on schedule within a day. We are very satisfied with our new system and truly appreciate the dedication and service provided by Coastal. Highly recommended.

• We used Coastal before for an emergency fix on the heat pumps in our former home two years ago. Based on their professionalism and prompt service, we knew we would use them for future projects. Mike and his team did a fantastic job installing a Mitsubishi mini split system in our new home recently. The team that did the work were incredibly friendly, efficient and knowledgeable. Lisa in the office was very courteous and helpful. Mike was always available to answer any technical questions or assist with the Mass Save Heat Loan and Rebates. The team installed our system in a day and spent the time showing us how to use the new system as well as the Mitsubishi app. We would 100% recommend Coastal Heating and Air Conditioning to anyone!!!

• Excellent Service from Start to Finish! I recently had a new HVAC system installed in my home, and I couldn't be happier with the experience. From the initial consultation to the final walkthrough, the team was professional, punctual, and knowledgeable. They took the time to assess my home’s specific needs and recommended a system that was energy-efficient and within my budget. The installation was completed on time, with minimal disruption, and the crew left the workspace clean and tidy. They made sure everything was running perfectly before they left. Since the installation, my home has been consistently comfortable, and hope to see a drop in my energy bills. Highly recommend this company for anyone looking for reliable and high-quality HVAC installation!

• 5 stars isn't enough. During a heat wave (105°) I called, and because I wasn't a long-time customer, they just couldn't fit me in. They gave me a couple of phone #s to call, and I got an appointment for the next day. They called me back and said they could squeeze me in, but I said I was all set. That was until I got a quote. To try to keep this short, the quote was outrageous. I called Lisa, and she had her guys out, and they gave me a quote for a full heat pump replacement that was $11,000 cheaper than I had. It got easier after that. Lisa contacted me almost daily to arrange everything. Day of installation everyone was on time, clean and professional. And they were done before their scheduled finish time. The owner Mike was fantastic to deal with. Nick, Alex, and Dana were amazing, but Lisa is special. She doesn't know me from a whole in the wall, but cared about me and everything like we were lifelong friends. This is the Company and People you want to deal with. No exceptions. And I will recommend them to everyone I know.

• *Update- the owner Mike called me and apologized for the poor customer service. He was very kind and understanding and is refunding us for the second visit.* We hired Coastal to fix the AC in our condo. Unfortunately, it stopped working again less than 2 weeks after the initial repair. They came back and told us the entire system needed to be replaced because our R22 refrigerant was low. We were told by the tech, Alex, the second visit would be no charge but ended up getting an invoice anyway, which we did pay. In total we paid ~$750 for the two visits and were unfortunately still without AC. When we called to discuss the estimate for a full system replacement, the customer service experience was very disappointing. We asked if there was any flexibly on pricing given what we had already paid. The woman on the phone responded with hostility and seemed to get angry at me for even asking. She abruptly ended the call with “good luck” and hung up on me. After this upsetting interaction, we got a second opinion. It turns out the R22 levels were in fact not low- the real issue was the internal fan speed setting simply needed to be increased. Our AC now works perfectly, and we avoided spending over $10,000 on an unnecessary replacement. If you’re considering working with Coastal, I strongly recommend getting a second opinion.

• Sent someone out, who said would have quote within week. 2 weeks later I called and they said they don't want the job because no plywood on floor of attic. That is easily remedied and very unprofessional that someone wouldn't contact me to let me know.

  Eric E.★★★★★

• Mike's team at Coastal provided excellent service from the point of first contact to questions following the completion of the work. On both the administrative side, and the labor side, they were courteous, efficient, and performed above expectations. Would highly recommend Coastal Heating, Air Conditioning, and Plumbing to anyone in need!
