Performing tune up service on 2002 Bryant and 1998 Rheem package units for Brentwood Press. Thoroughly cleaned units, specifically the condenser coils that were compacted with debris cutting off airflow through units. Airflow is important in keeping the compressor motors from overheating. Systems are running better to keep the hot press offices cool. Tested and inspected all electrical and safety components, tested refrigerant levels and repaired a broken duct.

Diagnostic service on 2013 Carrier condenser for a certified member, not running on arrival. Found a low voltage fuse was blown. Diagnosed failed contactor that had caused the fuse to blow, replaced the fuse and contactor and the system is now up and running! Being certified members got these clients same-day service and discounts on repairs but most importantly gives them peace of mind in knowing that we are here to take care of them quickly and keep their system running as long as possible.
