As summer approaches and temperatures rise, your air conditioner becomes essential for keeping your home cool. One important part of your AC system is the refrigerant coil, which helps transfer heat and cool the air inside your home. However, these coils can develop problems that affect your AC’s performance. Here’s a simple guide to common issues with refrigerant coils and how to handle them.
What Are Refrigerant Coils?
Refrigerant coils come in two types:
- Indoor coils (evaporator coils) are inside the air handler unit and absorb heat from the indoor air.
- Outdoor coils (condenser coils) are in the outside unit and release heat into the air.
These coils are usually made of copper or aluminum tubes with thin fins that help in heat transfer. If they develop issues, your AC may not cool properly, leading to discomfort and higher energy bills.

Common Problems with Refrigerant Coils
1. Refrigerant Leaks
One of the most common problems is a refrigerant leak. This can happen due to corrosion, poor installation, or general wear and tear. Signs of a leak include:
- Weak or uneven cooling
- Hissing or bubbling sounds
- Ice forming on the coils or refrigerant lines
Ignoring a refrigerant leak can damage your AC’s compressor and lead to expensive repairs. It’s best to call a professional technician to fix the leak and refill the refrigerant.
2. Coil Corrosion
Over time, refrigerant coils can corrode due to moisture, chemicals, or pollutants in the air. Corrosion weakens the coils, causing leaks and reducing efficiency. To prevent this:
- Schedule regular AC maintenance
- Keep the coils clean
- Change air filters regularly
If corrosion is found, repairs or coil replacement may be needed to restore efficiency.
3. Coil Freezing
When moisture in the air freezes on the coils, your AC may stop cooling properly. This can be caused by:
- Blocked airflow from dirty air filters or blocked vents
- Low refrigerant levels
- Dirty coils
If you see ice forming on the coils, switch off your AC and allow the ice to melt. Then, check for clogged filters or vents. If the problem continues, call a technician for a full inspection.
Why Regular Maintenance is Important
Fixing refrigerant coil problems early can prevent expensive repairs and keep your AC running efficiently. Neglecting these issues can lead to higher energy bills, poor cooling, and system breakdowns. Scheduling routine AC check-ups with a professional can help detect problems early.
