My AC seems to be leaking oil. The charge has been corrected and blower motor replaced. Could it be evap coil?

There is no opening for the evap. coil, the installers seemed to want it to be a mystery. I can't check if it's dirty, I'm assuming yes, it is. We recently remodeled and I'm thinking the dry wall dust did something. It's been running today, now there's a pool of what seems to be oil around the bottom of the unit. Any suggestions?? Thanks!My AC seems to be leaking oil. The charge has been corrected and blower motor replaced. Could it be evap coil?
Evaporator coils (normally located atop an upflow furnace or air-handler) are sometimes very difficult to access for inspection and cleaning purposes. The reason is because it is the inside surfaces of the A-coil that need to be inspected. And this can only be done by looking upwards from the bottom side of the coil.





In order to achieve this it is sometimes necessary to slide the coil outwards from the top of the furnace. To do this sheet metal may need to be removed (and replaced) and it is possible that the two copper lines may be attached to the coil in such a way as to make doing this extremely difficult. A competent HVAC technician can determine if an air movement problem exists by taking several air temperature measurements. Sounds like a job for an HVAC contractor.

I do not think it is leaking oil, it is probably water from condensation.





Is the AC a window (wall) mount or is it central air.





If it is a window (wall) mount, the installers should have mounted the unit at an angle with the bottom rear tilted slightly down. What this does is allow condensation to drain out of the back of the unit and harmlessly outside. Make sure they installed it properly.





If the problem unit is a central unit, call the service company back and have them come back and fix it.
