We live in the mountains of western NC. Two years ago January-maybe 3, we replaced a 10 year old heat pump with a Carrier. Our house is about 1900 SQ. Ft. and we payed about $10,000 for the Carrier. The house is abot 13 year old and we enlarged the unit from the previous one which was just on the edge for size of house. It’s been fabulous. Someone else mentioned getting a good installer is crucial and it was. The installer- owner was bright and knowledgeable and always available when needed. That price included an electronic air cleaner and a humidifier. The unit truly keeps the dust down and the marvel of summer air-conditioning is that when we open up in the morning to get fresh air in or at night, when we turn on the air-conditioner, it almost immediately takes the humidity out of the air. We didn’t buy the top of the line but at that time it was the next to the top of the line. Hope this helps. When we had ours replaced in a relatively mild January, We felt lucky since the following winter nobody could have gotten up our icy mountain and we would have been in real trouble.
So, 10,000 for your units. We don’t have the summer humidity that NC would have. Winter heating is important here.
Thanks for your information.
