The controller is the brain of a walk-in, display case or reach-in. It manages temperature, defrost, fans and alarms. A failing or poorly programmed controller can cost you product and energy. Liberty HVAC installs, replaces and programs refrigeration controllers across Brooklyn, Queens, the Bronx, Staten Island, Manhattan, Nassau and Westchester.

Signs of a controller problem
- Temperatures drift even though the system runs
- Defrost doesn't start, doesn't end or runs too long
- Error codes or alarms on the display
- Ice build-up on the evaporator
- Fans or compressor behaving erratically
Why upgrade
Modern electronic controllers give tighter temperature control and smarter defrost, which saves energy and protects product. Some offer alarms that warn you before a small problem becomes a loss.
