If you suspect an evaporator coil problem,
+1 (844) 611-2488What Is an Evaporator Coil Leak?
The evaporator coil is located inside your indoor air handler or furnace and plays a vital role in absorbing heat from your home's air. Refrigerant circulates through the coil, allowing your AC system to cool indoor spaces efficiently.When the coil develops a leak, refrigerant slowly escapes. As refrigerant levels drop, your system loses cooling capacity and must work much harder to maintain the desired temperature.
Common symptoms include:
- Warm air coming from vents
- Longer cooling cycles
- Ice forming on the evaporator coil
- Higher electricity bills
- Hissing sounds near the indoor unit
- Poor humidity control
+1 (844) 611-2488Why Do Evaporator Coils Leak?
+1 (844) 611-2488Formicary Corrosion
One of the most common causes is microscopic corrosion caused by household chemicals, cleaning products, and airborne contaminants. Tiny tunnels develop within the copper tubing, eventually allowing refrigerant to escape.
+1 (844) 611-2488Age and Wear
Most evaporator coils last 10–15 years. As they age, repeated heating and cooling cycles weaken the metal.
+1 (844) 611-2488Vibration
Constant operation causes small vibrations that may weaken solder joints or tubing over time.

Although uncommon, some coils develop premature leaks because of production defects.If you're unsure what's causing the issue, professional leak detection is the safest approach. Schedule an inspection today by calling

The refrigerant circuit is tested to confirm leak locations before repairs begin.Professional diagnostics prevent unnecessary repairs and help determine whether repairing or replacing the evaporator coil is the better investment. To book service, call
+1 (844) 611-2488Repair or Replace the Evaporator Coil?
Several factors determine the best solution.Repair May Be Appropriate When:
- Leak is minor
- System is relatively new
- Coil remains under manufacturer warranty
- Refrigerant type is still readily available
Replacement Is Often Better When:
- Multiple leaks are present
- Coil is heavily corroded
- AC system is over 10 years old
- Repair costs approach replacement value
+1 (844) 611-2488Steps to Take If You Suspect a Leak
1. Turn Off Your AC
Running the system with low refrigerant can damage the compressor.2. Check the Air Filter
A clogged filter can worsen airflow problems, although it won't cause refrigerant leaks.3. Inspect for Ice
Frozen coils often indicate refrigerant or airflow issues.4. Schedule Professional Service
Avoid adding refrigerant without repairing the leak. Simply recharging the system is only a temporary solution and does not fix the underlying problem.For prompt HVAC service in Clovis, call
