Mike, Thanks for the email and your request for a technical review of the Goodman Model GPH15M Packaged Heat Pump. A good friend of mine has a relationship with Goodman dealer as an installing contractor and I forwarded your email to him to let him give his perspective on the Goodman review you requested. Here is his technical review of the packaged heat pump unit:

Goodman GPG15M Package Unit Reviews | Consumer Ratings - The Technical Details

Richard The Goodman GPG15M Packaged Heat Pump comes from a long line of excellent package units. The Goodman line carries a 10-year warranty on parts. Just remember to register it online within 60 days of the installation (except in California or Quebec) to obtain the warranty. The 4 and 5-ton applications bring even greater savings to the table with 2 stage compressors.

All of the units in this line come with an Energy Efficient Motor and are multi-positional. This unit is also running on R-410A refrigerant, as per the new law in effect 01/01/10. That adds an extra dimension to the heating capability of the unit running without auxiliary heat, because of the much higher operating pressures of R-410A as compared to R-22 at the same outdoor ambient temperatures. That translates to a much higher heat of compression output flowing to the indoor coil during the heat mode, which gives you a much warmer register airflow temperature.

Air Source Heat Pump Tips | Dual Fuel Heating

A dual fuel heat pump is a heat pump with a gas furnace for backup heating rather than electric heat strips.

Air source heat pumps have a backup heating source. In most installations, the backup heating source is electric heat strips. Electric heat strips are very cheap to install in most cases. However, while electricity is generally regarded as 100% efficient, producing it is more costly than other heating methods. For a more efficient heat pump, consider a dual fuel heat pump, or a heat pump with a gas furnace for the backup heat source. It will be more costly to install, but your monthly bills will be reduced.

That translates to much less of a “drafty” heat pump feeling, which I can testify to. I upgraded from R-22 to R-410A seven years ago( 7.65 SEER to 13.15 SEER), and noticed a huge difference in the airflow temps. When I upgraded last year from that Lennox unit to an Amana 18 SEER, 2 stage compressor, Variable speed outdoor fan, and indoor blower, with new ductwork, I felt another distinct improvement in airflow temps in heating, and my auxiliary heat strips have yet to come on, even when we were in the upper teens temperature-wise recently.

Even my wife hasn’t been complaining at all and she is quite cold-natured. I think he will be very happy with his new Goodman unit, as long as it is properly installed per the manufacturer’s installation instructions and all local codes as required, to a well-insulated, sized, and sealed duct system. Good Luck
