New Construction Options
Our original bid from the builder has a single stage variable speed 95.5 Carrier gas furnace with a single zone for duct. Our house is a two story (2700 sq ft above grade) with a basement in northern Minnesota. Our builder said that a multi-zone system will not work that great and you can get the same results by closing registers. My question is, are the following options worth the added cost? Any experiences would be helpful.
Is it worth it to do the following?
1. Three zones for heating (upper, main, and basement)
2. Two stage furnace upgrade ($900 more)
3. Basement in floor heat rough-in ($2,700)
