Lets face it, 1 slide chart can not do it all. Don't be fooled by an abridged chart with missing information, tidbits of random formulas and rule of thumb calculations all crammed on to one chart. The HVAC 3-Pack comes with 3 charts. One for sizing ductwork, one for calculating superheat/subcooling on R-22 systems and one for calculating superheat/subcooling on R-410a systems. Duct calculator has diagrams for properly calculating total equivalent length and pressure drop correction factors. A must have for high efficiency systems. Put one chart in your install bag and the others in your service bag.
