Waiting for a refrigeration system to fail is expensive. Preventive maintenance is one of the most effective ways to reduce surprise breakdowns, protect product, and extend equipment life. Arctic Spark Controls offers maintenance programs tailored to the type of refrigeration equipment you operate and how critical it is to your business. During a maintenance visit, we clean condenser coils, check evaporator coils and fans, verify defrost operation, inspect and clear drains, check door gaskets, and confirm that controls and sensors are working correctly. We also review superheat, subcooling, and operating pressures to spot developing issues like low charge or restricted metering devices.
