Commercial Refrigeration Repair

Reach-ins, prep tables, display cases, and remote racks — back in temperature fast.

When refrigeration goes down in a restaurant, grocery, convenience store, or bar, the clock starts immediately: product at risk, health code exposure, and lost sales. GERARDO HVAC LLC repairs and maintains commercial refrigeration equipment across Fort Dodge, Webster City, Humboldt, and Eagle Grove, Iowa. I service reach-in coolers and freezers, under-counter units, sandwich and pizza prep tables, refrigerated display cases, bar coolers, and remote condensing systems. Every call starts with getting your product safe and ends with an honest explanation of what failed and what it takes to keep it from happening again.

Signs You Need Commercial Refrigeration Repair

Box or case temperature drifting above safe holding range
Compressor running constantly and never satisfying setpoint
Heavy frost or ice buildup on the evaporator coil
Water pooling under or inside the cabinet
Condensing unit short cycling or tripping its breaker
Product spoiling faster than it should
Loud compressor noise, hard starts, or a hot condensing unit
Door gaskets torn, hardened, or no longer sealing

How I Approach Commercial Refrigeration Repair

Refrigeration diagnostics are about the whole system, not just the symptom. I verify the actual product temperature against the controller reading, check the defrost cycle and termination, inspect the evaporator and condenser coils, test the fan motors and defrost heaters, take suction and discharge pressures, and calculate superheat to evaluate the metering device and charge. I check door gaskets, hinges, and heaters since air infiltration is one of the most common causes of an underperforming box, and I look for oil traces that indicate a refrigerant leak. Leaks get found and repaired properly — brazed, nitrogen pressure tested, evacuated, and weighed in — rather than topped off month after month.

Why Choose GERARDO HVAC LLC

Refrigeration is unforgiving of guesswork. A unit that is 'a little warm' can cost you thousands in product and a health inspection headache. I diagnose with gauges and temperature readings rather than assumptions, I give you a straight price before I start, and I will tell you when equipment has reached the point where continued repairs no longer make financial sense. For food-service customers I can usually work around service hours so your kitchen keeps running.

Commercial Refrigeration Repair — FAQs

How fast can you respond to a refrigeration emergency?

Refrigeration failures with product at risk get priority, and same-day service is often available across Fort Dodge and the surrounding towns. Call or text (515) 206-3232 and you reach me directly.

What temperature should my commercial cooler hold?

Coolers should hold product at or below 41°F and freezers at 0°F or colder. If your box is drifting above that, it needs attention before it becomes a health code problem.

Why does ice keep building up on my evaporator coil?

Usually a defrost problem — a failed heater, timer, or termination sensor — or excessive humidity entering through bad door gaskets. Both are repairable, and both get worse if ignored.

Do you service remote condensing units and rack systems?

Yes, along with self-contained equipment. Remote systems get the same approach: full pressure and temperature diagnostics before any part is replaced.

Should I repair or replace an older refrigeration unit?

It depends on the failure. A fan motor or controller on a solid cabinet is worth repairing. A failed compressor combined with a leaking coil on a fifteen-year-old unit usually is not. I will give you the numbers and let you decide.
