Commercial & Industrial Refrigeration Installation, Repair and Maintenance
Commercial and industrial refrigeration installation, repair, and preventive maintenance for facilities in Chicagoland, Northern Illinois & Indiana.
What this covers
Scope
- We install, troubleshoot, and repair commercial and industrial refrigeration systems supporting cold storage, processing, and warehouse operations.
- We service compressors, condensing units, evaporators, expansion valves, defrost circuits, and refrigerant piping networks.
- We execute refrigeration retrofits and new system installations for facility build-outs and equipment upgrades.
- We integrate refrigeration temperature monitoring, defrost scheduling, and high-temperature alarm points with facility controls and BAS platforms.
Problems we solve
- Walk-in and process temperature excursions put perishable inventory, stored materials, and active production batches at risk.
- Iced evaporator coils, malfunctioning defrost controls, and moisture infiltration choke airflow and overwork refrigeration compressors.
- Fouled condensers, failing fan motors, and refrigerant charge faults cause high-head-pressure trips during hot weather.
- Recurring piping leaks make older refrigeration systems costly and unreliable to keep online.
Service modes
How we work it
24/7 emergency
Around-the-clock emergency dispatch puts technicians on-site across Chicagoland, Northern Illinois & Indiana when refrigeration failures threaten temperature-sensitive product or production.
Planned work
We sequence new refrigeration installations and retrofits with general contractors and plant managers to protect active storage and process schedules.
Maintenance
Preventive maintenance contracts keep condensers clean, defrost controls calibrated, door and drain heaters verified, and refrigerant circuits tight year-round.
In the shop
Our in-house fabrication shop builds custom structural supports, welded assemblies, and auxiliary cooling skids when standard refrigeration packages do not fit site constraints.
FAQ
Questions facility managers ask
Do you handle emergency refrigeration breakdowns outside normal business hours?
Yes, Pro Tech Contractors provides around-the-clock emergency refrigeration repair for commercial and industrial facilities across Chicagoland, Northern Illinois & Indiana. Technicians mobilize from our Lombard office to diagnose compressor, control, defrost, and leak faults before product loss escalates.
Can you retrofit existing refrigeration equipment?
We assess system condition, piping integrity, and cooling load to determine whether a retrofit or full equipment replacement fits. Once scoped, we schedule the changeout around your inventory and production constraints.
Can refrigeration temperature alarms connect to our building automation system?
Yes, our controls capability lets us tie refrigeration temperature sensors, defrost status, and fault alarms directly into your facility BAS. Central visibility helps facility teams catch drift early rather than discovering a warm box after inventory is compromised.
