10/31/2025- I arrived on site and found the gas valve was faulty, causing the furnace to attempt to ignite but fail due to this faulty gas valve. This unit is covered under a manufacture parts warranty and I have ordered the warranty gas valve. The customer has approved of the labor estimate for the replacement of the valve. Please contact the customer and schedule a timeframe for replacement of the gas valve. This unit will not heat until this valve has been replaced.
