Refrigeration Services

Reliable refrigeration is critical to daily operations. When temperatures drift, product quality, safety, and profits are at risk. At E-R HVAC, we specialize in low-temperature and medium-temperature refrigeration systems designed for walk-in freezers, walk-in coolers, and commercial refrigeration equipment located at ground level or indoors. We service, repair, and maintain commercial freezers and coolers—not rooftop units and not evaporative (swamp) coolers.

What Are Low-Temp & Medium-Temp Refrigeration Systems?

Medium-temperature systems are designed to keep products cold, typically between 34°F and 41°F. These systems are commonly used in:

  • Walk-in coolers

  • Reach-in coolers

  • Beverage coolers

  • Food prep and storage areas

Low-temperature systems are designed to freeze and preserve products at 0°F or below. These systems are commonly used in:

  • Walk-in freezers

  • Commercial freezers

  • Ice storage and frozen food areas

Both systems rely on precise refrigeration cycles. Even small performance issues can lead to temperature loss, product spoilage, and equipment strain.

Signs Your Freezer or Cooler Needs Service

Refrigeration problems often start small and worsen quickly. Watch for these common warning signs:

  • Temperature fluctuations or inconsistent cooling

  • Frost buildup on coils or inside the unit

  • Ice forming where it shouldn’t

  • Unusual noises such as buzzing, grinding, or clicking

  • Compressor running constantly

  • Warm air coming from vents

  • Leaking water or refrigerant odors

  • Higher energy bills without increased usage

  • Product thawing or condensation inside the unit

If you’re noticing one or more of these, contact us today!
