i can install you a brand new Goodman 2 ton heat pump or gas pack , with full ten year parts warranty the install cost is the same for a 1 1/2 ton heat pump as it is for a 5 ton gas pack The only differance is the unit and shroud cost . These installs are premium installs with real square to round fittings , for better airflow into and out of the unit, not "flat tapped" .a new Honeywell digital thermostat and a new shroud.
