From The Ask The Expert Mailbox……..

Is it normal operation for my heat pump to turn on and off

constantly during very cold temeratures (5 degrees above zero)?  My heat pump turned off and on all night last night.

Mark,

Thanks for the question. It is not normal for your heatpump to turn off and on, this is called short cycling. If your back-up heat for the heatpump is a gas furnace, your heatpump should not be on at all due to the cold temperatures. If your back-up heat for the heatpump is an electric furnace your heatpump should run continously until the thermostat is satisfied.

Please feel free to call me at 243-3581 or send me other questions you may have.

Thanks,
