I need some help with HVAC planning for a duplex I am currently looking to build. It will be located in South West Manitoba aka Zone 7A from looking at the map.
I have a couple of options…
1) Stick built on site. This would give me the option of a slab foundation aka hydronic radiant heat.
2) RTM moved onto crawl space foundation. This would not allow for hydronic radiant unless I attached the lines to the underside of the RTM flooring (not inside a slab).
I know I could just go baseboard electric heat, but the monthly bills would definitely be higher. I do have access to NG so it would seem like a no brainer to go with NG to reduce monthly bills even further. I am kind of hoping to not run a furnace in each side as they would take up valuable space in the units. I am not completely against it however, if it is the best option.
I am looking for AC for the summers as well. I have been tossing up the idea of a split mini ductless, but they will most likely not suffice in the extreme winters we get (don’t want renters bitching about lack of heat).
What is the best option or combination of options while keeping costs relatively sane? Thanks!
