Evaporator Coils
What Are Evaporator Coils?
Evaporator coils sit inside your indoor AC unit, usually attached to the furnace or air handler. These copper or aluminum coils are filled with refrigerant that absorbs heat from the air in your home. As warm air passes over the coils, the refrigerant cools it down before sending the conditioned air back through your ductwork.
Because evaporator coils are responsible for absorbing heat and moisture, they’re highly vulnerable to dirt, corrosion, and wear. When coils become dirty or damaged, your system struggles to operate efficiently, often resulting in higher utility costs and less comfort indoors.
Common Evaporator Coil Problems
- Frozen Coils – Ice buildup restricts airflow and signals problems with refrigerant levels, air filters, or airflow
- Refrigerant Leaks – Tiny cracks in the coils can cause refrigerant to escape, reducing efficiency and cooling power
- Dirty or Clogged Coils – Dust and debris accumulate over time, making it harder for coils to absorb heat
- Corrosion – Especially in humid climates, coils may corrode, weakening the metal and creating leaks
Signs Your Evaporator Coil Needs Attention
Recognizing warning signs early can save you from costly repairs or full system replacements. Common symptoms include:
- Weak airflow from vents – Even when the fan is running, air feels light or uneven
- Warm air from the AC – Instead of cooling, the system circulates lukewarm air
- Excess indoor humidity – AC isn’t removing enough moisture from the air
- Frequent cycling – System turns on and off more often than normal
- High utility bills – Rising costs with no change in usage often indicate inefficiency
If you notice any of these signs, it’s time to schedule professional evaporator coil service before the problem escalates.
