    I originally looked into the Arzel system and only found 1 local contractor that installed them. When I recently went to their website it looks like they dropped Arzel for Emme. The Emme sounded...

    Opinions on Emme zoning system...

    Can anyone comment on how good or bad an Emme zoning system is? It sounds really cool and would work well with my modulating furnace and 2 stage ac unit. Is arzel better or worse?

    Still looking into HV systems but refuse to give up good efficiency. Now I see spacepak makes an Aircell model with an ECM motor. Any experiences or opinions? Is it efficient or still not?

    Ductless mini split question

  33. Ductwork question - starts small then gets bigger
