The geothermal heat pump is considered to be the most efficient type of heat pump available, and also the most expensive. This type of unit uses the constant temperature of the earth as its exchange medium instead of the outside air, and it can have a life span of more than 20 years if properly maintained.
High cooling efficiency heat pumps: Generally speaking, models rated at 18 SEER and above should be considered highly efficient heat pumps. Some of the highest efficiency air-source heat pumps are rated at up to 20.5 SEER.
