Reschedule the spring pm b/c the customer she didnâ€™t have air filters she needs to be changed.
I went into the attic and basement with the vacuum cleaner and cleaned the drain lines. I used a brush inside the traps and flushed with water to push any debris down the drain line. Both drains are free from obstruction and both have safety devices installed. I checked the filters and they are clean. Coils and blower wheels are clean. I checked the electrical wiring and electrical systems, all are within specification. Both units are cooling with normal delta temperatures. Units are operating normal. I recommended installing hard start kits to each unit outdoors. These devices take the strain at start up off the compressor and greatly help to prevent compressor failure due to shorted out internal windings. Customer will talk to there husband about adding these.
On arrival found system not operating,found gas pressure not set correctly.adjusted gas pressures ,also configured furnace To bring the fan on when heat pump is running .system operating normal
Furnace would fire up when it had set for a while but would not fire back up when it was hot. I checked the pressure being pulled by the inducer and it was under 1.25 unless the furnace had time to cool off. I went through every procedure to rule out causes of low draft pressure, including checking drain tubes to the collector box and the collector box itself. I cut the exhaust pipe to see if the pressure increased and removed the burner compartment door but the draft pressure hardly increased. This lead me to pull as much off to inspect the heat exchanger. Using a scoping camera I was able to go around a bend to find the cause, a cracked heat exchanger in the area with severe discoloration due to overheating. I was able to show the customer the crack. I made the furnace inoperable and turned the gas off. A sales person is coming out tomorrow to quote replacement. Customer does not want this to happen with a new furnace.
