Seven boilers: that is how many a recent customer said Coastal Climate Controls has cleaned for them, calling the company thorough and knowledgeable. The company says it has handled heating, ventilation, air conditioning and plumbing in the Sebago Lakes Region since 2018, and a local news site has described it as founded by Sean Thomson. A recent customer who was referred to Sean by neighbors, after a bigger HVAC company blew off appointments and did a lackluster job servicing the boiler, said Sean responded immediately and came out the next day. That customer said that after getting the parts, Sean got the boiler back up and running and installed Ecobee thermostats. A recent customer said Sean walked them through the issue and helped them understand how their boiler operates and what they can do to keep it running well. A recent customer said that in the thick of a heatwave, with their system not keeping up, Sean came out, diagnosed the issue and solved it faster than HVAC techs they had worked with in previous years. On Google the company holds 5 stars from 34 ratings.

“Founded by industry veteran Sean Thomson, Coastal Climate Controls has earned a strong reputation for honest service, expert craftsmanship, and developing positive long-standing customer relationships.”
I’ve had Coastal Climate clean seven boilers for me, and the service has been outstanding every time. They’re thorough, knowledgeable, and clearly take pride in doing the job right. It’s rare to find a company I’d trust with that much work without hesitation, but they’ve earned it. I couldn’t recommend them more highly.
Sean was extremely helpful and knowledgeable. He walked me through the issue and helped me understand better how my boiler operates, and what I can do to keep it running well.
I was referred to Sean from my neighbors after dealing unsuccessfully with a bigger HVAC company who basically blew off my appointments and did a lackluster job servicing my Boiler. Sean immediately responded and came out the next day. After getting the parts today he got the boiler back up and running and installed my Ecobee Thermostats. If you want someone who’s dedicated, who cares, who’s knowledgeable and just a good person call Coastal Climate Controls.
Sean is incredibly responsive and knowledgeable! We were in the thick of a heatwave and our system wasn’t keeping up. Sean came out and was able to diagnose the issue and solve for it faster than HVAC techs we’ve worked with in previous years. Highly recommend Coastal Climate Controls!
