Performed a preferred customer furnace cleaning. Cleaned the burners and the flame sensor. Checked the furnace heat exchanger. Wiped down the inside of the furnace. Checked the electrical. Cycled the furnace and performed a furnace combustion test. No issues with the furnace at this time. Looks like the air conditioner hasn’t been serviced in a long time. Recommended getting an air conditioning cleaning to make sure the air conditioner is running properly and efficiently.
