"Big shout out to Jon and the Tetra team!"

I got a fair quote, they did the work and kept me apprised throughout the process and problem solved when we hit a few roadblocks. At the end of the day they did a great job on a difficult project. Best of all?
No upsells or extras and they charged exactly what we agreed to.
Thank you!

"Will be using them again!"

Tetra installed a heat pump and a water tank for me. The communication was easy, and the installation was fast and professional. Will be using them again.

"Tetra did a great job and delivered on all the things they said they were going to do."

Tetra did a great job and delivered on all the things they said they were going to do. They helped me out with the Loan process and working with me and my electricians. Jon Legg, Jet Li and Randy Nel were very helpful with any of my concerns. The install crew was great as well. They did 5 heads and my compressor all in one day. Unbelievable. Thank you Tetra

"Tetra did a wonderful job with the mini-split system they installed."

Tetra did a wonderful job with the mini-split system they installed. The install team was very accommodating and willing to work with us in the design stage. The installation itself was quick and painless. Finally, Tetra make is super easy to apply for the rebates and takes away the guess work. I highly recommend them for any heat pump/mini-split work you want done.

"The installation process was very smooth."

Tetra has been wonderful to work with. The installation process was very smooth. The best part, though, has been the ongoing customer service. If we ever have a problem or a question, they are incredibly responsive, and they get it taken care of very quickly. I highly recommend working with them.

This company is exactly what you hope for when investing your money into something which can be hard to find nowadays.
