A residential AC system that suddenly stops cooling can be frustrating-especially when the outdoor unit won’t even turn on. In my cases, the issue goes beyond a simple electrical problem.
In this case study, we share how Universal Refrigeration Services LLC diagnosed a non-cooling system and identified a refrigerant leak in the evaporator coil-leading to a full warranty replacement.
The problem
The homeowner reported that the AC system was not cooling and the outdoor condensing unit was not running.
Diagnostic Process
- Verified incoming voltage to the system
- Confirmed thermostat was calling for cooling
- Set up gauges to check system pressures
- Detected low refrigerant levels
- System was not starting due to the low-pressure safety switch
Finding the Issue
After safely shutting down the system, we used an electronic leak detector to inspect the system. A refrigerant leak was found in the evaporator coil.
The Repair
Universal Refrigeration Services LLC verified that the system was still under manufacturer warranty.
We handled the entired process:
- Contacted the manufacturer
- Submitted the warranty claim
- Ordered the replacement evaporator coil
Once the new coil arrived, we completed the installation and tested the system.
The system was restored to proper working condition.
Cost to Client
Since the system was under warranty, the client did not pay for the evaporator coil. The client only paid for labor, refrigerant, and necessary materials.
