Customer Question

Hi - my name is ***** ***** and I am having a problem with my Lennox HVAC unit - seems as though when there is a demand for heating, the ignitor is not lighting and it is not producing heat
JA: Thanks. Can you give me any more details about your issue?
Customer: the diagnostic code on the furnace has a slow blinking green light, which could mean 1 of 4 things: (1) pressure switch open, (2) blocked inlet/exhaust vent, (3) condensate line blocked (for condensing furnaces only), or (4) pressure switch closed priot to activation of combustion air inducer those are listing on the front of the furnace "Diagnostic codes/status of furnace"
JA: OK got it. Last thing — HVAC Technicians generally expect a deposit of about $18 to help with your type of question (you only pay if satisfied).
