No heat upstairs due to a clogged draft inducer motor port. I had to open the draft inducer motor, in order to clear the port. Tested system multiple times, with no issues. Recommend to install an in line switch, to the drain line, to prevent water in the drain pan, and to sign up for home care maintenance program. Home care maintenance program gives two visits for hvac, one free whole house electrical and plumbing inspection, 10% off any repair.
