NJinspector Posted July 26, 2008 Report Share Posted July 26, 2008 When the client booked the inspection, he had never seen this type of heating system. Said the heating unit was outdoor with the a/c unit. Right away, i think heat pump. This is not a heat pump (i think), what is it? How does it work? Anyone have some info I can pass on to the client? thanks in advance Image Insert: 64.65 KB Image Insert: 70.95 KB Image Insert: 69.39 KB Quote Link to comment Share on other sites More sharing options...
Neal Lewis Posted July 26, 2008 Report Share Posted July 26, 2008 Jason, That's gas pack heating/air con unit. The label probably says it's for natural gas. See the gas line? The exhaust is right under the gas shut off valve. Is that flexible gas connector rated for exterior use? Quote Link to comment Share on other sites More sharing options...
Brian G Posted July 26, 2008 Report Share Posted July 26, 2008 Down here we just call 'em "package units". They can be heat pumps or gas heat with AC. They're actually getting a little more popular these days, because all the noise is outside. Brian G.

Richard Moore Posted July 26, 2008 Report Share Posted July 26, 2008 Not seen anything like that. So...I assume that ductwork is split into supply and return air. Filter(s) at the interior return grills or is that the reason for the odd "tent" shape? Is that enough exposed ductwork to be concerned about insulation or is it double-walled? One last question and I promise to shut up...Does that lower section also contain the emergency heat strips? Quote Link to comment Share on other sites More sharing options...
hausdok Posted July 26, 2008 Report Share Posted July 26, 2008 Hi Richard, Think combo gas furnace and AC unit mounted on the roof of a commercial building and it's essentially the same thing. I've done about a dozen of those on various commercial buildings and in one case on the roof of a high end condo. They're not much different than an ordinary gas furnace only they're placed outside and they don't require a chimney. ONE TEAM - ONE FIGHT!!!

Brad Manor Posted July 26, 2008 Report Share Posted July 26, 2008 They're pretty common around here on houses without basements. -Brad Quote Link to comment Share on other sites More sharing options...

Filter(s) at the interior return grills or is that the reason for the odd "tent" shape? Correct again about the typical filter location, but I have no idea what that tent shape is. Is that enough exposed ductwork to be concerned about insulation or is it double-walled? Around here it would just be insulated inside. I'm sure that may vary in other regions. One last question and I promise to shut up...Does that lower section also contain the emergency heat strips? I've not seen a two-tiered unit before, but normally there would be no emergency heat strips in a gas unit. Brian G.

msteger Posted July 26, 2008 Report Share Posted July 26, 2008 Can't say I've ever seen a system like that either. Quote Link to comment Share on other sites More sharing options...
