Tetra did an amazing job, they were very professional, quick and knowledgeable. The communication throughout the process was great which really put my mind at ease.The installers were a great professional team of 6 guys. only 2 spoke English but everyone sure knew what they were doing and did it extremely well and fast. They finished a 5 unit job with 3 ceiling units (working in a small cramped attic) in just ONE day. Great workmanship, cleaned up after themselves, respected the house and worked efficiently.I would highly recommend this company.

We started working with Melissa while we were exploring options for replacing our oil heating system with a heat pump system in our home. She was kind, empathetic, and always understood our sense of urgency with our particular situation. She was extremely communicative via email, phone, and text, which we very much appreciated. Ultimately we needed to install the system through other means, but we were very impressed by Melissa and her team's professionalism, and would recommend them for anyone searching for a heat pump system for their home.
