•Heating issues in Sugar Hill Georgia. •Priority issue is the system needs a new outside defrost board / defrost sensor . Board / sensor is not working properly. •Short on Return air would highly recommend bringing the return intake to speck cfms for better airflow and allow the system to work properly . Will benefit the equipment with better static pressure. •Would recommend a maintenance program on the HVAC equipment to allow us to service the equipment twice a year . •Family is going with replacing the outside board and sensor. Replaced . Will send over the other recommendations.
