PG heat pump efficiency: 5 outdoor models compared
PG has 5 heat pump outdoor models certified with this refrigerant group, in 5 AHRI-certified combinations. Each model is compared with models of the same size and duct type, so the scores below do not depend on which sizes PG makes. PG has no QMID (IRS Qualified Manufacturer ID) on file, so it is not ranked against other manufacturers.
