Refrigerant Leak Detection — The Delfino Difference

What sets Delfino Refrigeration apart from every other commercial refrigeration repair company is our commitment to finding and fixing refrigerant leaks. Most HVAC contractors will respond to a low-refrigerant call by simply topping off the system and sending a bill. That approach costs you money every time the refrigerant leaks out again — and it does nothing to address the underlying problem.

Delfino Refrigeration goes the extra mile. Our technicians use advanced leak detection equipment and proven diagnostic techniques to locate even the smallest refrigerant leaks in your commercial refrigeration system. We repair the leak at its source, recharge your system to manufacturer specifications, and verify that the repair holds. This approach saves our customers thousands of dollars in repeated service calls, wasted refrigerant, and the hidden energy costs of a system that’s constantly running low.

Commercial HVAC Repair — Frequently Asked Questions

What makes Delfino Refrigeration different from other commercial refrigeration repair companies?

The biggest difference is our approach to refrigerant leaks. While other commercial refrigeration repair companies simply add refrigerant and leave, Delfino Refrigeration goes the extra mile to find and fix the actual leak. This saves our customers from repeated service calls, wasted refrigerant, spoiled products, and the inflated energy bills that come from a system running low on refrigerant. Our EPA-certified technicians use advanced leak detection methods to locate even the smallest leaks and make permanent repairs.

How do I know if my commercial refrigeration system has a refrigerant leak?

Common signs of a commercial refrigeration leak include: your cooler or freezer isn’t maintaining proper temperature, the compressor runs constantly without cycling off, ice buildup on evaporator coils, higher than normal energy bills, or a HVAC technician has had to add refrigerant more than once in the past year. If you’re experiencing any of these symptoms, call Delfino Refrigeration at 847-650-6444 for a thorough commercial refrigeration leak inspection.

How often should commercial refrigeration equipment be serviced?

We recommend commercial refrigeration maintenance at least twice per year — once in spring before summer heat puts maximum demand on your equipment, and once in fall to ensure everything is running efficiently heading into winter. High-use environments like restaurants and grocery stores benefit from quarterly commercial refrigeration maintenance. Delfino Refrigeration offers customized maintenance plans tailored to your specific equipment and business needs.

Can Delfino Refrigeration help reduce my commercial refrigeration energy costs?

Absolutely. Inefficient commercial refrigeration equipment is one of the largest energy drains for businesses. Delfino Refrigeration’s maintenance services include coil cleaning, gasket inspection, refrigerant level optimization, and thermostat calibration — all of which directly reduce energy consumption. We also identify equipment that’s reached the end of its efficient lifespan and provide honest recommendations about repair versus replacement.

What is the warranty on Delfino Refrigeration’s commercial refrigeration repairs?

All commercial refrigeration repairs performed by Delfino Refrigeration are backed by our 45-day parts and labor warranty. This covers the specific repair work performed and the parts installed. We stand behind every job and will return at no additional charge if an issue arises with a repair we’ve completed within the warranty period.
