You can that information directly from the manufacturer of you preference. They want to get this information out to the general public. It's in their best interest to do so. You must first decide which manufacturer to go with and then call them to get the contact info for your local rep. If you’re inquiring about the best efficiencies, it's the ground source geothermal heat pump units. Air source heat pumps lose efficiency when the temperatures goes (roughly) below 45 degrees and must utilize a backup heating source like an electric heating strip coil. Geothermal ground source heat pumps work with the earth’s consistent temperature 3 feet below grade level. This makes it easier to design for the heating/cooling load and it doesn't require a backup heating source, although you can surely add one.
