Today we visited because when the heat was turned on Jennifer experienced a burning smell. We learned the smell was from the supply plenum. The unit was installed without a heat shield/start collar. The odor was from a small portion of the duct board being too close to the heat strips. The supply plenum was repaired using plenum washers and plenum screws. During the diagnosis we learned the airflow was not adjusted when the unit was installed and the system was working with a high static pressure. The high airflow caused mildew growth inside the unit and ductwork. Since the ductwork is not accessible we installed a REME air and surface purification system. The system is working great and the air quality issue is now resolved.
