Refrigerant Leak Causing AC Failure in Scottsdale, AZ

At All Seasons Plumbing and Air, we know just how crucial a well-functioning air conditioner is—especially during the scorching summers in Scottsdale, AZ. So when a local homeowner contacted us about an AC unit that was running but not cooling, we jumped into action. After a thorough inspection, we discovered the culprit: a refrigerant leak.

This project involved careful diagnostics, expert leak detection, and a complete system recharge. In this post, we’re breaking down exactly what happened, how we fixed it, and why addressing refrigerant leaks quickly is so important.

The homeowner’s main complaint was that their air conditioner was constantly running, but the air inside the house remained warm and humid. This is a classic red flag for low refrigerant levels, which usually signals a leak somewhere in the system.

Refrigerant is essential for cooling—it absorbs heat from the air and moves it outside. Without enough of it, the AC system struggles to do its job. Even though the fan may still be blowing air, it won’t feel cool. This not only compromises comfort but also forces the unit to work harder, which can drive up energy costs and reduce the system’s lifespan.

Our experienced HVAC technician arrived on-site promptly and began with a complete system inspection. We checked the thermostat settings, air filters, and refrigerant pressure levels. The pressure readings confirmed what we suspected: the system was low on refrigerant.

To pinpoint the exact location of the leak, we used a combination of electronic leak detection tools and UV dye testing. After a detailed search, we found the leak in one of the refrigerant lines located near the condenser coil.

We walked the homeowner through our findings and explained their options. They chose to move forward with a full, permanent repair rather than a temporary fix—a smart decision that ensures long-term performance.

Here’s how we handled the repair:

• Sealed the Leak: We accessed the affected line and performed a precise repair to stop the leak.
• Evacuated the System: We completely evacuated any remaining refrigerant and moisture from the system to prepare it for recharging.
• Recharged with Refrigerant: We added the correct amount of refrigerant, as specified by the manufacturer, to ensure peak performance.
• Tested the System: We ran a full performance check, including airflow, temperature differential, and compressor function, to confirm the repair was successful.

Once the system was repaired and recharged, it began cooling immediately. The homeowner noticed a dramatic improvement in comfort within the first hour. The air coming through the vents was cold and consistent, and the system no longer had to run non-stop to reach the desired temperature.

Not only did we restore the cooling, but the homeowner also gained peace of mind knowing their system was running safely and efficiently again. We also discussed the benefits of enrolling in a seasonal maintenance plan to catch these types of issues before they turn into emergencies.

Refrigerant leaks may seem like a minor issue at first, but they can quickly escalate into major problems. Ignoring a leak can result in:

• Compressor damage – one of the costliest AC repairs
• Increased energy bills due to system overwork
• Poor indoor comfort and inconsistent cooling
• Environmental harm, as many refrigerants are greenhouse gases
• The earlier a leak is detected and fixed, the better the outcome for both your wallet and your HVAC system.
