Performed annual hvac maintenance 10 yr Rheem package unit ground. Found primary drain line not hooked up correctly. See pictures need fitting pvc 3/4 female and some fitting to get it to drain away from unit. House appears to have been recently stuccoed over spray on unit. Cleaned off as best I could. Recommend outside coil clean. Unit is loosing efficiency with how dirty it is. Indoor coil starting to have build up. Checked dual capacitor ok. 70-10. Control board ok. No burn marks or loose wires. At 10 yrs old system is in need of a good cleaning to help with Efficiency. Can’t get accurate refrigerant numbers until coils are fully cleaned. Cooler day refrigerant numbers look to be ok, house cooling well. Flushed drain line.
