I am trying to pick a system for a new house I am having built. The contractor is trying to get me to install 2 heat-pump units. One upstairs and one in the basement.
I think I only want one unit installed. It would be propane. I do not like electric heat or heat-pumps. It would have a DC blower motor that I would run 24 hours a day to keep the air circulating (it costs almost nothing to run a DC motor), with an electric filter like the clean affects. I think I could have a return air in the basement and upstairs to pull air from both areas. I would also have a 2 stage unit. I am not sure what seer or efficiency rating to get on the furnace. I am thinking maybe 90 % on the furnace and 13 seer 2 stage AC.
The builder is telling me that the walkout basement even though it is well insulated will have a much different temperature than upstairs. I am thinking if I am always moving air that the temperatures would equalize somewhat. I don't want the cost of installing and maintaining 2 HVAC units.
Please I am open to any advise and suggestions.
