As a business owner in Arizona, your walk-in cooler is the heart of your operations. Whether you run a restaurant in Phoenix or a floral shop in Tucson, a temperature spike can lead to thousands of dollars in lost inventory. If your unit is struggling to stay cold, you need expert walk-in cooler repair before a minor issue becomes a total system failure.

At Discount AC & Refrigeration, we hold Arizona License ROC 361623 and specialize in keeping commercial systems running efficiently.

1. Frost Buildup on Evaporator Coils

One of the most common reasons a cooler loses its chill is ice. When airflow is restricted, moisture freezes on the coils. This often points to a faulty defrost timer or a clogged drain line. Regular preventive maintenance is the best way to prevent this.

2. Dirty Condenser Coils

Your condenser coils dissipate heat. If they are covered in dust or grease, the system has to work twice as hard, leading to a “warm” cooler. According to ASHRAE standards, dirty coils can increase energy consumption by up to 30%.

3. Damaged Door Gaskets

Check your seals! If air is leaking, your compressor will cycle constantly. This is a critical part of commercial HVAC health.

4. Low Refrigerant Levels

A leak in the lines means your cooler can’t remove heat effectively. If you suspect a leak, contact our emergency repair team immediately.

5. Faulty Evaporator Fan Motor

If the fans aren’t blowing, the cold air stays trapped at the coil instead of circulating throughout the unit.

6. Incorrect Thermostat Calibration

Sometimes the fix is simple. A miscalibrated thermostat might tell the system it’s colder than it actually is.
