Supermarkets depend on reliable refrigeration systems to keep food safe, fresh, and appealing to customers. From open display cases to walk-in freezers, these systems run around the clock — which means even small problems can lead to major losses.
At Buffo’s Refrigeration, we’ve worked with grocery stores and supermarkets across Nevada, helping them diagnose, repair, and prevent refrigeration problems before they lead to downtime or product spoilage. Here are some of the most common issues we see — and how to avoid them.
Inconsistent Temperatures
Uneven cooling is one of the most frequent supermarket refrigeration problems. It can cause some sections of a display to freeze while others stay too warm, creating food safety and quality issues.
Common causes:
- Dirty condenser or evaporator coils
- Blocked airflow or overstocked cases
- Faulty thermostats or sensors
- Failing fan motors
Solution:
Routine maintenance from Buffo’s Refrigeration keeps airflow clear, sensors calibrated, and coils clean — ensuring even cooling throughout your displays and storage units.
Ice or Frost Buildup
While some frost is normal, excessive buildup can indicate an airflow issue or a failing defrost cycle. Over time, frost restricts cooling efficiency and makes compressors work harder, leading to higher energy costs and premature wear.
Solution:
Regular defrost cycle checks, proper gasket seals, and coil cleaning help maintain balanced humidity and prevent ice accumulation.
Refrigerant Leaks
Low refrigerant levels reduce cooling capacity and force your system to run longer, increasing both wear and energy consumption. Leaks can also cause uneven temperatures and system failure if not detected early.
Solution:
Buffo’s Refrigeration technicians use advanced leak detection tools to find and repair leaks promptly, then recharge the system with the proper refrigerant to restore efficiency.
Compressor Failure
The compressor is the heart of any refrigeration system. When it fails, cooling stops altogether. Compressor issues often stem from poor maintenance, electrical problems, or restricted airflow.
Solution:
Our team inspects compressors during every maintenance visit, checking electrical connections, refrigerant levels, and component wear to prevent unexpected breakdowns.
Door Seal and Gasket Damage
Damaged or worn door gaskets allow warm air to enter, forcing the system to work harder and leading to temperature fluctuations. This is one of the simplest yet most common causes of poor performance in supermarket coolers and freezers.
Solution:
Replacing gaskets is quick and cost-effective. Buffo’s Refrigeration stocks a wide range of commercial gaskets and seals to ensure an airtight fit for all cooler and freezer types.
Electrical or Control System Malfunctions
Modern supermarket refrigeration relies on digital controls, sensors, and electronic valves. Electrical failures or control board malfunctions can cause temperature errors, compressor cycling issues, or complete system shutdowns.
Solution:
Our technicians are trained in both mechanical and electronic diagnostics. We identify electrical issues, replace faulty components, and verify system calibration to keep everything operating safely and efficiently.
