Service was performed at scheduled time, technician examined both the outside unit and the condenser inside. Lines were flushed and outside unit coils were cleaned. The service performed was explained. I was very satisfied with the service.

The cement connecting the furnace to the AC vents was leaking air in the attic and he put a mesh and tape and cement that sealed it. Eric did a great job!
