Reliable refrigeration service for North Texas businesses

Commercial refrigeration is the backbone of your operation — whether you run a restaurant, a convenience store, a cold storage facility, or a healthcare clinic. When your refrigeration equipment fails, you face product loss, health code risk, and lost revenue by the hour. Rock Hard Refrigeration exists to get your systems back online fast and keep them running reliably long term.

We specialize exclusively in commercial refrigeration and HVAC — not residential calls. Every technician on our team works on commercial equipment every day, which means faster diagnosis, fewer callbacks, and repairs done right the first time.

From emergency refrigeration repair to full walk-in cooler installations and planned preventative maintenance, we cover the complete lifecycle of your refrigeration equipment throughout Aubrey, Frisco, McKinney, Plano, and all of North Texas.

Warning signs your refrigeration system needs service

Catching a problem early prevents a small repair from becoming a full system replacement — and protects your inventory from loss.

Temperature Running High
If your unit is reading above its setpoint consistently — like 42°F climbing toward 53°F — there's a refrigerant, compressor, or airflow issue that needs immediate attention.
Excessive Ice Buildup
Ice accumulation on evaporator coils or the freezer floor is a clear sign of a failed defrost sensor, drain line blockage, or door seal problem.
Water on the Floor
Condensate pooling around or under a refrigeration unit signals a clogged drain line or a defrost system that's not completing its cycle correctly.
Unusual Noises
Banging, clicking, rattling, or a compressor that short-cycles on and off are symptoms of failing components — fan motors, compressors, or loose internal parts.
Running Constantly
A refrigeration system that never cycles off is working harder than it should. This drives up your energy bills and signals low refrigerant, dirty coils, or a refrigerant leak.
High-Temp Alarms
A high-temperature alarm is never a false positive you should reset and ignore. It means your system isn't maintaining safe storage temperatures — call us immediately.
