Types of Air Conditioners
-
Window AC Unit
A window AC unit is a compact solution that often struggles with extreme heat or heavy usage. If your air conditioner is not blowing cold air but running, filters, coils, or internal fans may be to blame. These units benefit greatly from seasonal tune-ups.
-
Central Air Conditioner
A central air conditioner cools your entire space efficiently. If it is not cooling enough, it typically indicates dirty filters, low refrigerant, or airflow restrictions. Regular maintenance ensures this system operates smoothly, saving you money and energy over time.
-
Mini Split AC
A mini split AC offers zoned cooling and operates quietly. However, if your split AC compressor is not working but the fan is running, the issue may involve refrigerant levels, electrical faults, or sensor failures. These systems require precise, brand-specific diagnostics to restore performance.
Common AC Problems and Their Causes
-
Central Air Conditioner Not Cooling Enough
The most common reason AC stops working is a clogged AC air filter or a low refrigerant level. Dirt restricts airflow, strains your system, and reduces efficiency. Replacing filters and checking refrigerant regularly can prevent these problems before they start.
-
Split AC Compressor Not Working
If your split AC compressor is not working, but the fan is running, it could mean a bad capacitor, refrigerant leak, or complete compressor failure. This kind of issue needs expert attention to avoid escalating damage and increased energy consumption.
-
AC Thermostat Not Working
If your AC thermostat is not working, it could throw off your entire cooling system. The issue may be as minor as dead batteries or as major as faulty sensors and wiring. Accurate thermostat control is essential for both comfort and energy savings.

FAQ
Why is my AC blowing hot air?
Your AC compressor may not be running, or the system could be low on refrigerant. A dirty evaporator or clogged AC condenser can also be the root cause.
Why is my AC leaking water?
This can stem from a blocked drain line, frozen evaporator coil, or loose drainage connections. Dirty filters are another common culprit.
Why is my AC fan not working?
A faulty motor or capacitor may be the cause. If your AC unit fan is not spinning, it's best to call a technician to avoid further issues.
How often should I replace my AC filter?
Every 90 days is standard. A dirty air filter reduces airflow, stresses your system, and can lead to costly breakdowns.
How do I fix my air conditioner?
First, check the thermostat, breaker, and AC air filter. If the issue persists, contact a pro. We'll guide you through what's wrong and how we'll fix it. AC Repair LLC is your trusted partner when your AC is not working. We bring honesty, professionalism, and fast action — every time.
