I purchased this new house over a year ago. It came with a climate master 4ton tranquility 27 with a horizontal loop system in the front yard. This unit runs non stop when the weather drops below 30degrees and it costs me almost 20 dollars a day paying 14 cents a kWh. I have ran with the auxiliary units disconnected and it doesn’t make a difference. My house is 2400 sq feet with high ceilings and I do have a basement. We have 3 zones and use 2 of them through the winter... what am I missing? Why are my winter bills 500 to 600???
