Commercial refrigeration repair and maintenance
Walk-in coolers and freezers, cold storage, display cases, ice machines and compressor racks — repaired and maintained by a licensed C38 refrigeration contractor. When product is at stake, the call goes to the front of the line.
- Licensed C38 refrigeration contractor
- 14 years serving Valley businesses
- Also C20 HVAC & C43 sheet metal
A cooler that's running warm is money leaving the building.
The Central Valley runs on cold storage. Grocers, restaurants, floral shops, dairies, packing houses and processors all depend on refrigeration that holds temperature every hour of the day — through 105° summers, through the weekend, through the one night nobody is watching. When it drifts, inventory spoils, inspections fail and customers notice.
JP Air Conditioning & Heating is a licensed C38 refrigeration contractor serving Fresno and the entire Central Valley for 14 years. We repair and maintain walk-ins, cold rooms, display cases, ice machines, condensing units and compressor racks, along with the electrical, controls and defrost systems that keep them holding temp. Because we also hold C20 HVAC and C43 sheet metal licenses, we can handle the air side and the ductwork on the same visit.

Refrigeration equipment we repair, maintain and replace
Walk-in coolers & freezers
Evaporators, condensing units, doors and gaskets, defrost systems and thermostats for walk-in boxes of every size.
Cold storage & cold rooms
Large cold rooms, produce and floral storage, and staging coolers for packing and processing — with the airflow to hold temp evenly across the room.
Compressor racks & condensing units
Parallel rack systems and remote condensing units — compressors, oil systems, condenser fans, controls and refrigerant circuits.
Display cases & reach-ins
Open and closed merchandisers, deli and meat cases, reach-in coolers and freezers, prep tables and under-counter units.
Ice machines
Commercial ice makers and bins — cleaning, water and refrigeration-side repairs, and replacement when production drops off.
Refrigerant & leak repair
Leak detection, brazing and repair, recovery, evacuation and charging — including questions about older refrigerants and retrofits.
Controls, defrost & monitoring
Thermostats, defrost timers and heaters, pressure controls, alarms and temperature monitoring so a problem is caught before product is lost.
Replacement & new equipment
Condensing units, evaporators, racks and complete walk-in systems sized for the load, installed and started up by our crew.
Refrigeration is a license, not a side job
Plenty of HVAC companies will "take a look" at a walk-in. Commercial refrigeration is its own trade, with its own license — California C38 — and its own failure modes: low-temp systems, defrost cycles, oil return, pressure controls and product that can't wait until Monday. JP holds the license and has worked on heavy commercial equipment since 2000.
- Product-first priorityA box running warm with inventory inside is treated as urgent. Tell us what's at risk when you call.
- Root-cause repairsWe fix why it froze up or lost temp — airflow, defrost, charge, controls — not just the symptom that got you to call.
- One contractor for the whole buildingRefrigeration, HVAC and sheet metal on the same license set means one crew and one number for restaurants, markets and plants.
- Maintenance that prevents the 2 a.m. callCoil cleaning, gasket and door checks, defrost verification and refrigerant checks on a schedule built around your operation.
Call before the product is gone
Refrigeration failures rarely come out of nowhere. These are the symptoms we hear most from Fresno-area operators — and the ones that are cheapest to fix early.
- Box won't hold temperatureLow charge, dirty condenser, failed fan motor, bad door gaskets or a defrost problem — all fixable, none of them wait well.
- Evaporator coil frozen solidFailed defrost heater or timer, low airflow, or low refrigerant. Thawing it out is not a repair — finding the cause is.
- Compressor running constantlyHigh head pressure, a leak, or a box that's been loaded past what the system can do — and a compressor headed for failure.
- Water on the floor or ice on the ceilingClogged drain lines, failed drain heaters and air leaks around doors — slip hazards and inspection problems.
- Ice machine slow or making cloudy iceScale, water filters, dirty condensers or refrigeration faults — most are maintenance, some are the start of a replacement conversation.
- Rising power billsDirty coils, failing gaskets and short-cycling compressors run up the meter long before they finally quit.
From your call to a box that holds temp
Call with what's at risk
Tell us the equipment, the temperature it's holding, and what's inside. Product-at-risk calls are prioritized.
On-site diagnosis
A technician checks charge, pressures, airflow, defrost, electrical and controls and identifies the actual cause.
Straight options
What's wrong, what it costs to fix, and when replacement makes more sense than another repair on an aging unit.
Repair, verify, prevent
The system is repaired and pulled down to temp, and we'll recommend a maintenance schedule so it stays there.
Scheduled service for equipment that can't afford a bad weekend
Condenser and evaporator coil cleaning, door and gasket checks, defrost and drain verification, refrigerant and electrical checks, and ice machine cleaning — on a schedule built around your operation. Fewer emergency calls, lower power bills, and equipment that lasts years longer.
Commercial refrigeration FAQ
Do you work on residential refrigerators?
No — we focus on commercial refrigeration: walk-ins, cold rooms, display cases, ice machines, condensing units and compressor racks for businesses. For a home refrigerator, an appliance repair service is the right call.
My walk-in is warm right now. How fast can you get here?
Call us at (559) 253-3265 and tell us what's inside the box. Product-at-risk calls are put at the front of the schedule. In the meantime, keep the door closed as much as possible and don't load anything new into the box.
How often should commercial refrigeration be serviced?
Most operations do well with quarterly maintenance — coil cleaning, gasket and door checks, defrost and drain verification and a refrigerant check. Dusty or high-heat environments like packing houses and outdoor condensing units in Fresno summers often need more frequent coil cleaning.
Can you replace a compressor, or do I need a whole new system?
Often a compressor or condensing unit can be replaced on its own. We'll look at the age and condition of the rest of the system, the refrigerant it uses and the repair history, and lay out both options with real numbers before you decide.
Do you install new walk-ins and refrigeration systems?
Yes. We size and install condensing units, evaporators, racks and complete walk-in systems for new locations, expansions and replacements, and start them up and verify they hold temperature.
