The easiest way to determine your energy efficiency on a heat pump, gas furnace, or air conditioner is to look at the seer rating. The higher the seer rating the more efficient and cost effective the system will be over the long run, be warned though, a more efficient system will also run more up front, make sure to calculate how long it will take for the savings on your utility bill to match the difference in price for a high efficiency unit. Ductless heat pumps will always have the highest efficiency of any heating or cooling unit, followed by heat pumps, and finally air conditioners.
A/C vs Heat Pump
Typically a heat pump is more efficient than an Air Conditioner in the northwest climate, however, there are limitations to heat pumps in temperatures above ninety degrees and below 25 degrees Fahrenheit. Typically in our climate we only spend a couple weeks a year outside of the efficiency range of a heat pump, this is why most contractors recommend heat pumps over air conditioners here. Also the air conditioner is limited in the sense that it can only run cool air and not both hot and cold air like a heat pump.
Efficiency vs wall, ceiling, wood, baseboard, window units
As a general rule, installing a heating and air conditioning system in a home that has wall, ceiling, baseboard, wood, or floor heat and or a window unit will save between 25-50% on your utility bill. Keep in mind that most homes that do not have a system installed in their home have only heating built in, this means that you might spend a little more in summer months than you currently do because you probably aren’t running anything except for a fan in your home.
