Damper on room 4 wasn’t opened all the way not allowing enough airflow into the room. Also noticed the thermostat that controls room 4 is also in the sunlight in the waiting room. Mentioned that would also be affecting it to shut off before it actually met temperature. Adjusted damper to allow more airflow & he said he would test it out now that it’s blowing harder in room 4. Other than that no issues to report.
