My fiance and I are building our first home. We purchased some basic house plans that are designed for a slab on grade home. I am really leaning towards slab on grade for the aesthetics, savings, as well as for environmental reasons. I live in New England and our winters are consistently below freezing and our summers frequently hit the high 80s and low 90s with bad humidity. Based on these factors, what type of heating and cooling system should we be looking into? I feel like if we go with a slab on grade we would almost certainly have to get radiant floor heating otherwise the exposed cement would get very cold in the winter. With that said, we would most likely also want to get some form of forced air system to heat our second floor as well as provide cooling to both floors in the summer. The forced air would also help maintain air quality in the home year round.
The above system in my mind would be ideal, but it also seems expensive to have both radiant floor heating AND forced air, especially when one of the reasons we are choosing a slab on grade is to save some money.
