Dual-fuel heat pumps are truly the "best of both worlds." These pumps take the advantages of both gas powered and electrical powered heat pumps and eliminate the disadvantages. These systems are technically air source electric heat pumps, but they combine that system with a gas furnace. This enables consumers to enjoy cost-efficient and very high temperature heat in practically any season.

One of the primary disadvantages of air source electric pumps is that they do not function quite as well in extremely cold temperatures. If you are living in a below freezing region and have to contend with -35 degree temperatures for months on end, a typical air electric source pump will eventually prove to be too problematic. This device extracts heat from the cold air-naturally, it's going to be unstable, as the weather itself is unstable.
