Tetra HVAC installation reviews

"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!

"It was the most smooth transaction I have ever experienced."

From the minute I inquired about the mini split system it was the most smooth transaction I have ever experienced. Every person though out the process was so helpful and very nice. Customer service was excellent and was there if you needed anything. I would HIGHLY recommend Tetra to anyone that is thinking of installing these amazing units!!! The team that came to install the system were so hard working, and did not even take a break.

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.

"I felt like their staff were truly interested in helping us get the best possible results for our home."

Tetra installed our minisplit system last year. The installers did a great job and Tetra was great to work with throughout. Tetra's staff were immediately accessible when I had questions or needed guidance with documents necessary for rebates, a loan, and warranties. Tetra's experts on mini-splits and hybrid electric water heaters provided essential guidance as I had no prior knowledge regarding these kinds of appliances. I did lots of comparison research and remember in particular how respectfully their hybrid electric water heater expert shared the pros and cons of water heaters that Tetra offered and didn't offer. I felt like their staff were truly interested in helping us get the best possible results for our home. Another way of stating this: I always felt that I was working with expert consultants and not sales people out to make a buck. I recommend this company highly and without reservation.

"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.

Frequently asked questions

How do I know what size furnace is right for my home?

The best way to determine the correct furnace size for your home is to choose a reputable installer. At Tetra, we calculate your home’s heating needs based on industry standards. These calculations take the climate and your home’s size, design, and construction into account. A furnace that’s too small for your home won’t keep your house comfortable in extremely cold weather. Most furnaces are slightly bigger than necessary to avoid this possibility, but a furnace that’s too large will cycle on and off more frequently. This causes wear and on the components, uncomfortable fluctuations in temperature, and noisy airflow—not to mention, it wastes a lot of energy.

What are "zones"?

A zone is an are in your home, which is controlled by its own thermostat. A home can have anywhere from 1-5 zones based on size, layout, or additions. Zoned HVAC uses dampers in the ductwork to regulate and redirect air to specific areas of the home.

What is “heat load”?

Heat load is the amount of heat energy your home needs in order to maintain the desired indoor temperature. Your home’s heat load depends on its size, construction, insulation, number of windows, and other factors. The heat load will also determine the size and model of furnace your home needs. Speak to one of our experts about the new furnace cost and the best furnace for your home.

How long does a furnace typically last?

The lifespan of a furnace can vary depending on factors such as maintenance, usage, and quality of installation. On average, a well-maintained furnace can last 15-20 years or more.
