Job Checkin

I found flame sensor current to low. Also, furnace is in need of cleaning. Replaced flame sensor. Tested operation. Temperature rise very high. I replaced customer’s air filter. Checked temperature rise. 56. I found return air duct is open where it is against the wall!! Apparently had a return air vent on the other side of the wall. wall Has been closed off! System is relying on only the return air duct that comes down from the attic. This only remaining ducting is too small for this equipment. Return duct pressure: -.35 inches water column. Suggestions: need to schedule first visit for maintenance plan purchased today. Customer would like a price to replace the furnace and to correct the duct issues.
