What HVAC would you install?
As we see the duplexes and triplexes arrive here in Toronto. I wonder what HVAC they are installing in those small units? I came across this duplex, with a lower-level separate living unit below a two storey living unit. Heating load for the top is 21,875 BTU/hr, heating load for the bottom is10,487 BTU/hr. Cooling for top (equipment size recommendation not cooling load) 1.5 tons, bottom is 1 ton. Ductwork is available. What HVAC would you install ? For the last 50 years or more in this area ( Toronto, Ontario, Canada) the gas furnace, with forced air fan and ductwork has been the heating system of choice.
