A pet hotel in LA County reported that the humidity in their lobby area felt high today. Our A/C technician arrived and inspected the York lobby unit. Found the return grill badly clogged and the unit's coils dirty as well. On the roof, our tech found #2 had a grounded compressor. Compressor and drier will need to be replaced, coils and return grills cleaned. To provide more airflow, we also recommend adding an extra return grill for this unit. Will quote all necessary work and provide options to the customer.
