Arrived to do a heating maintenance. Turned on the furnace from the thermostat. Checked the system heat exchanger. Checked the system air filter. Measured a temperature split and set the humidifier to run. Found that the humidifier panel was so heavily coated in calcium buildup, and that was causing water to drip on the floor. Checked blower for cleanliness and play in the bearings. Measured power consumption of each of the motors in the furnace. Verified operation of all mechanical and electronic components. Performed combustion analysis to ensure the system is heating efficiently within factory specifications. Furnace is functioning properly at this time.
