Great system
September 09, 2025I am very pleased with this unit, it is very silent compared to the system I had previously, you barely know when it is working. More importantly it seems to do a much better job at balancing the temperature in the house which is a two story cottage. Previously there was about 3.5 degree Celsius difference between the first and second floors, now there is barely 0.5 to 1 degree difference. I imagine this might be due to the variable speed blower. Overall, I am very happy with the system this far and anxious to see how it will operate in winter.
Yes, I recommend this product.
