Our house was always too hot upstairs and too cold downstairs (heat goes up) because we had a single zone AC/furnace system. I asked other companies how to solve the problem. One just said to close the upstairs vents, which I had tried but could still hear the air pressure pushing at it all night. Another said it was too difficult in such a small house. However, Sandium came up with a great 2-zone system for a reasonable price. Downstairs and upstairs can now be set to the exact temperatures we want. Thanks so much Sandium. They also did a great job fixing leaks in the attic duct work.
