“Worked with them for two different properties. Both times the experience was smooth and easy.”

“I had a ductless mini split installed. Very professional, responsive, excellent quality, and exceptional price. Half the costs of all other bids I got for the job.”
Mike L.
Ductless Mini Split, Brockton, MA
Their pricing is very fair and they rely on great local companies. It's very refreshing! They helped us source and install both a tankless hot water system and a ductless mini split. Life changing.

Excellent all around experience!! Love how easy this entire process was!
Diana E.
Ductless Mini Split, Holbrook, MA
We have had a great experience. They were willing to work around our work-from-home needs, and did a great job. We LOVE the mini-splits. So far, it's a much more comfortable fall, and we anticipate a cozier winter.

Parrish was so helpful, I had sort of a tricky configuration and lots of questions and he was great. Tiago and Matthew were amazing installers! Mike and Joe did an excellent job on the electrical install too,
Adriane E.

Everything was taken care of any issues I had were handled quickly by Tetra. The installers were great to deal with; the clean up could have been better, but over all I can say we are very satisfied with our project.
