Why Air-Source Heat Pumps Work Well In Temperate Climates

The Texas Panhandle’s climate is a perfect one for using air-source heat pumps. Although we occasionally experience bouts of freezing or colder weather, most of the time temperatures are well within the range to take advantage of the energy efficiency of heat pumps. Heat pumps simply move heat from one place to another. In the winter, they take it out of the outdoor air and in the summer, they remove it from your home.

There’s almost always enough heat in the air for heat pumps to work in our climate, since our temperatures are usually above freezing, when some heat pumps lose efficiency. An auxiliary heating coil kicks in, increasing the heat the system delivers.

Systems with higher heating performance can deliver warm air at even lower temperatures without having to use the auxiliary heating coil. Under most circumstances, the heat pump creates three times the heat from one unit of energy, compared to the coil, which has a one to one heating ratio.

In the winter, the pump captures the latent heat outdoors to change the refrigerant from a liquid to a gas. When refrigerant enters the evaporator coil, it absorbs the cold, releasing the heat, which is why your home warms.  In the summer, the cycle reverses and the pump removes the heat, cooling your home in the process.

The minimum energy efficiency of air-source heat pumps currently stands at 13 SEER (seasonal energy efficiency ratio) and a HSPF (heating season performance factor) of 7.5. Upgrades to heat pumps increase their heating and cooling efficiency. Since our cooling season is long, dual speed compressors can lower your energy bills by running the compressor at different speeds, slowing down when less cooling is needed.
