We had a great experience from start to finish! The installers were professional, courteous, prompt, efficient, as well as clearly knowledgeable and experienced. We appreciated how considerate they were of the fact they were in our home. They took time to answer any questions we had and for whatever explanations were needed. And we love having central AC!!

I am very pleased with the whole process. The people I talked to at Tetra were very helpful, guided me towards a system that was perfectly adapted to my needs (Bryant furnace hybrid gas/heat pump) and AO Smith hybrid heat pump/electric water heater. They also replied to my questions very quickly. The physical installation process was very smooth and very rapid (a few days) once I made my decision, the installers did not take any shortcuts and left the place very clean. The price was very competitive.

I am extremely satisfied with the exceptional service I received from the very beginning when I was asking for information up until the day of installation. I'm very appreciative with the smooth process. Very easy and stress free for me! I just can't say enough good things about Tetra. I would recommend them 100%.
