Our heat pump stopped on a Saturday because of a circuit board failure. We had a prompt service call, but had to wait without heat for a new circuit board. This was installed, but the system failed again after approximately 12 hours. Had to wait again for several days for a new circuit board to be obtained. When it came, Greg Funk, the technician on this call, "rebooted" the system before installing another circuit board and our system has now been working for several days. Kudos to Greg!
