Switching from 68 degrees to 70 degrees the heat pump will not shut off but has continued to run for as much as 2 hours before I manually shut the unit off. The 70 degree temp was reached within 20 minutes but the unit continues. The installation company says thus is normal, it is running through its cycle. I lived in Phoenix for 31 years and never had a heat pump do this. I live in Washington state and have only had the heat pump up and running for 4 days. Can you help me? Something is wrong.
