At Fast Affordable Air, we recently completed a repair project on a central air conditioning unit located on the roof of a residential building in Las Vegas. The homeowner reported issues with the system’s cooling efficiency and frequent cycling, which led to our HVAC team conducting a full system inspection. Upon investigation, we discovered a refrigerant coil leak that was significantly impacting the unit’s performance.
Diagnosing the Problem
In this case, the refrigerant leak was located in the evaporator coil. The evaporator coil is a critical component of any AC system, responsible for absorbing heat from inside the home to cool the air. When a leak occurs, the system loses refrigerant, which reduces its ability to transfer heat effectively and leads to higher energy consumption and reduced cooling.
You can see from the image (coil damage photo) that the refrigerant leak was caused by corrosion at one of the coil’s joints. This is a common issue with older systems, especially in climates like Las Vegas where dust and high temperatures can accelerate wear and tear on the AC components.
The Repair Process
After identifying the source of the leak, our Fast Affordable Air technicians began the repair process by shutting down the AC system and safely recovering any remaining refrigerant. Proper refrigerant handling is crucial, as these substances can be harmful to the environment.
We then carefully accessed the evaporator coil, as shown in the photos, to clean and prepare the area for repair. The damaged section of the coil was removed, and a high-quality, durable replacement was installed. This ensures the system is restored to optimal performance. After securing the new coil, we conducted a thorough pressure test to verify that there were no remaining leaks and that the new component was fully sealed.
Post-Repair Testing and Benefits
Once the repair was complete, our team recharged the system with the appropriate amount of refrigerant. Proper refrigerant levels are essential for maintaining an air conditioner’s efficiency and ensuring it provides the best possible cooling.
We then tested the unit to confirm it was functioning properly, checking airflow, thermostat response, and overall system operation. As you can see in the post-repair photos, the system is now running smoothly, and the ductwork connected to the AC unit was also inspected and resealed where necessary to avoid any future air leaks.
With the refrigerant coil leak repaired, the homeowners will experience:
- Improved Cooling Efficiency: The AC can now cool the home more effectively without overworking.
- Lower Energy Bills: With the system running more efficiently, energy consumption will decrease, leading to noticeable savings.
- Increased System Lifespan: Repairing the coil leak ensures that the air conditioner won’t have to work harder than necessary, which helps extend its overall lifespan.
