A struggling AC system in the middle of summer is a serious problem here in Illinois. AC problems don’t go away on their own, and are almost guaranteed to get worse if they aren’t fixed quickly. Knowing what’s going wrong with your system can save you time, stress, and money down the line. Let’s break down five of the most common AC repair problems and what needs to happen if you notice them.
1. Refrigerant Leaks
Low refrigerant is a major culprit when your system isn’t cooling effectively. You might notice longer run times, uneven cooling, or ice buildup on the lines. This isn’t just a refill-and-go situation—leaks need to be located and repaired by a certified professional before the refrigerant is replaced. Ignoring the leak can lead to compressor damage.
2. Frozen Evaporator Coils
If your AC is blowing warm air or not blowing at all, frozen coils could be the cause. Restricted airflow from a dirty air filter or blocked ductwork is often to blame. Turning off the system and replacing the air filter is a good start, but a professional will need to inspect the airflow system to restore proper function.
3. Dirty Condenser Coils
The outdoor unit takes in a lot of dirt and debris, especially during heavy spring pollen or mowing season. Dirty condenser coils limit heat exchange, making your AC work harder and wear out faster. A thorough coil cleaning from a technician helps bring cooling performance back to normal and protects your unit.
4. Faulty Capacitors
Capacitors are small but mighty components that help start and run the motors in your AC. If you hear a clicking noise or your system struggles to start, a bad capacitor could be the issue. These parts can’t be repaired and must be replaced, typically during a routine service call.
5. Thermostat Issues
Sometimes the problem isn’t with the AC unit at all—it’s with the thermostat. If your home feels off from the set temperature or the system short-cycles, the thermostat could be miscalibrated or outdated. A quick inspection or upgrade can fix communication issues between the thermostat and your system.
