HVAC Decoder vs HVAC Superheat & Subcooling

This app will decode the model number nomenclature of most HVAC companies. It has all the major brand names with many thousands of model numbers. It will also decode the serial number for many HVAC companies. It has the ability to email the search results in HTML format via an installed mail client. App is effective at decoding model and serial numbers for packaged units, air conditioners / condensing units, air handlers, evaporator coils, furnaces, heat pumps, boilers, chillers, split systems / mini splits, geothermal systems, and more.  If the model number is not found exactly it will try a close match. If there is no close match it will give you the option to report missing data. The data is constantly updated and purchase of the app gets you free updates forever.
