One system tune up in Lawrenceville. Arrived on site, found unit inoperable due to bad ignitor. Customer had a power outage and after the unit wouldn't come back on. Also found a degraded aux drain pan and no water safty, units gas line not up to code with flex line run directly into the gas valve, flue pipe is improperly ran coming out of furnace and and then at a downward angle this unable to properly vent combustible gasses. Blower motor assembly is dirty and motor has a weak capacitor. Evaporator coil is R22, corroded and needs to be cleaned. At this time due to age and condition of system I recommend replacing equipment, plenums and re running flue pipe. Will need to send a consultant out for a quote. Unit is not operational at this time. Turned power to unit off at furnace switch.
