Washington, D.C.

Today, I arrived on site for two scheduled maintenance tasks, including one for heating. Heating System Observations: Upstairs system was not operational. A wet switch had turned off the system. Noticed someone was tampering with the AC. Started the system in heat mode. Burner one tube was fluttering badly, even before blower activation. Performed a combustion test on the furnace; CO levels were within range. Detected CO in breathable air: 7 ppm in the attic and 40 ppm in the flue. Recommended replacement of the furnace due to safety concerns. Additional Recommendations: Scheduled a Comfort Advisor visit for next Tuesday to discuss furnace replacement. Noted that the furnace gas pipe obstructs removal; gas will need to be shut off to the house. Basement Furnace Maintenance: Installed a surge protector for the furnace blower motor and ensured it was grounded. Checked the operation of the basement furnace; it is functioning well at this time. The humidifier is operational

SOMETHING IS MAKING NOISE checked the noise complaint customer pointed at the condensate pump on a heat only furnace and humidifier making noise has a bad float switch that will not shut the pump off, pump needs replacing

Today, I arrived on site for heating maintenance on the boiler. Identified a leak at the expansion tank of the water heater. Informed the owner about the leak and will return to replace the expansion tank. Noticed the water heater requires a new gas shut-off valve. Observed that the boiler back flow and fill valve are nearly 10 years old. Recommended replacing the back flow and fill valve for unit safety and efficiency, as they should be replaced every 5-7 years. Pulled and cleaned the burner tubes and assembly for optimal performance. Customer requested installation of a T6 Pro WiFi thermostat for the boiler. Explained that the thermostat cannot control the boiler without a common wire. Suggested finding a battery-operated thermostat with WiFi capability as an alternative.
