Sound familiar?
If any of this is happening, it is worth a call
You do not need to know what failed. Describing the symptom is enough to get a real answer on the phone.
- Walk-in cooler or freezer holding above set point
- Heavy ice buildup on the evaporator
- Compressor short cycling or not starting
- Reach-in or prep table drifting warm
- Condenser fan not running
- Health inspection coming and temps are not holding
What the visit includes
The part most quotes leave out: what you actually get
Four things that separate a proper job from a parts swap. All four happen on every call.
Walk-in coolers and freezers
Charge, defrost cycle, door seals, evaporator and condenser condition, and controls — diagnosed as a system, not part by part.
Reach-ins and prep tables
Self-contained units where a small failure ruins a day of product.
Controls and defrost timers
A defrost cycle out of adjustment ices an evaporator solid and looks exactly like a refrigerant problem. It gets ruled out properly.
Preventive service scheduling
Regular condenser cleaning and gasket checks on a route schedule, so the failure does not happen during service hours.
Questions
Commercial Refrigeration, answered plainly
Do you handle emergency refrigeration calls?
Refrigeration calls with product at risk are prioritized. Call and describe what the temps are doing — that determines the response.
What size accounts do you take?
Light commercial: restaurants, convenience stores, small groceries, bars, and offices. Heavy commercial chiller and chilled water work is a planned expansion.
Can you service equipment you did not install?
Yes, across common commercial refrigeration brands.
