The heat pump is effective in many geographies, but especially in the southern United States.
In all electric applications, the heat pump may consume less energy than an electric furnace or air handler with an added electric heater accessory. Why? Because it can deliver the same amount of BTUs as electric heaters using less electrical input. In moderate climates the savings that natural gas yields may not be as advantageous as in colder climates, since there is less frequent use of the furnace in milder climates. Of course, the heat pump can be matched with a gas furnace where preferred. The heat pump is effective by itself down to temperatures around 25 to 30 degrees Fahrenheit. At that point, either a gas furnace or an air handler with supplemental electric heat will kick in and help heat your home. To determine which system would serve your specific needs best, your local Trane Comfort Specialist should perform a load calculation on your home and then estimate the cost of operation for the different combinations of equipment.
