FAQ/Myth
Answer/Response
You will want to check your service panel, or better yet, work with your installation contractor to evaluate your panel. If you have 100-amp electrical service, you will likely need an upgrade. There may be other considerations, such as having space on the panel or a dedicated circuit available, that also require upgrades. Talk to your utility if you are currently participating in a demand response program or want to learn about opportunities to participate, if applicable. Ask your contractor about the heat pump’s capabilities to be used in a demand response program. Yes, but it is much more common to have your thermostat/controller set up to automatically switch between the heat pump and your backup heat (sometimes called supplemental heat). The temperature at which the system switches to backup heat can be determined by your fuel type, your system’s performance capabilities, and the cost of your electricity and backup fuel. See the section on Controlling Your Heat Pump for more information.

You can find an HVAC Trade Ally contractor on the Focus on Energy Trade Ally tool. These contractors will also be able to inform you of any discounts offered.
Older heat pumps were known for cool air being blown during the start of a heating cycle. Modern variable speed or variable capacity heat pumps are designed to vary both the fan speeds and the refrigeration flow to reduce these issues, providing cozy heat at start up and throughout operation. It is true that heat pumps will deliver a slightly lower air temperature when compared to fossil fuel furnaces, but the difference has been getting smaller over time. There are periods of operation called “defrost cycles” designed to prevent frost from forming (or melting frost that does form) on the outdoor compressor coils. Depending on the size, type, brand, and efficiency of the heat pump you select, the method of defrost will differ and you may experience short periods of time, when the outdoor temperature is below 32°F, of cooler air cycling through your system. Work with your contractor to be sure you understand the defrost cycle on your system.
