Hey Guys, Anyone know much about current HVAC? The heat pup at our "shop" [ok - it's really the office] has a bum compressor in the outside unit, and the unit is mis-matched. It's 1.5 ton, and the in

Why? Using an oversize evaporator & air handler should not be a problem, and will actually be slightly more efficient overall. Of course you'll only get 1.5 tons of cooling, so the real question is

Care to expand on that concept, David? Remember the indoor unit is already oversized, so intended to handle more refrigerant flow than the old, inefficient compressor/condenser could produce. AFAIK,

already Lots and lots, it appears. High efficiency systems are just that, systems. They're engineered to work together. In high efficiency systems, the evaporator temperature has to be higher, and su

That would ... it's actually radiation from the sun that creates the ozone in the first place. Ozone quickly decomposes on it's own, so it takes continuous radiation to keep a layer present. And the
