Furnace Operational Safety Check

When we arrive at the home we first talk to the customers and listen to any concerns that they have about the equipment to give us a good idea of how the unit has been working recently. After that we go through a Twenty Point operational safety check check list:

• We visually check the equipment for any major safety concerns
• We look for signs of improper combustion at the burners, heat exchanger and flue pipe
• We check the motors and bearings and oil them if necessary
• We check the filtration system
• We check for gas leaks on the equipment
• We check the igniter or the pilot
• We clean the flame rod
• We check and cycle the thermostat.
• We check for proper ignition at all the burners
• We check the indoor blower time delay
• We check for proper flame composition.
• We check the flue gasses for safe CO, CO2 and O2 levels
• We check for proper vent drafting
• We check the temperature difference between the return and supply ducts
• We check the pressure switch, its hoses and connectors
• We check the fan and limit switches
• We check the unit for proper manufacturer’s sequence of operation
• We check the induced draft motor and its housing
• We check the gas control valve
• We check the ambient CO levels in the house
