When the Texas heat is in full swing, the last thing you want is an air conditioner that isn’t doing its job. If your AC is running but not cooling your home effectively, it could be due to several underlying issues. Whether it’s a clogged filter, refrigerant leak, or a faulty thermostat, understanding the root cause can help you determine if a simple fix will do or if it’s time to call for AC repair near you in New Braunfels.
In this guide, we’ll break down the most common reasons your AC isn’t cooling and when you should contact a professional HVAC technician.
Thermostat Issues
Your thermostat is the brain of your AC system. If it’s not set correctly or malfunctioning, your cooling system might not function as intended.
How to Fix It:
- Ensure the thermostat is set to “cool” mode and at the desired temperature.
- If you have a programmable thermostat, double-check the schedule settings.
- Replace the batteries if it’s a battery-operated model.
- If none of these work, the thermostat may be faulty and require professional replacement.
Refrigerant Leak
Refrigerant is essential for cooling your home. If there’s a leak, your AC won’t be able to absorb heat properly, leading to warm air blowing from your vents.
Signs of a Refrigerant Leak:
- AC is blowing warm air instead of cool air.
- Ice buildup on the refrigerant lines or evaporator coils.
- Hissing or bubbling sounds coming from the unit.
When to Call an Expert: Refrigerant leaks require professional repair, as handling refrigerant without certification is dangerous. If you suspect a leak, reach out to an HVAC technician for air conditioner repair in New Braunfels.
Dirty or Frozen Evaporator Coils
Evaporator coils absorb heat from your indoor air to cool it down. However, if they’re covered in dirt or ice, they can’t function properly.
Causes of Frozen Coils:
- Dirty air filters restricting airflow.
- Refrigerant issues causing the temperature to drop too low.
- Blocked vents preventing proper circulation.
How to Fix It:
- Turn off the AC to let the coils thaw.
- Check and replace the air filter.
- If freezing persists, call a professional for further inspection.
Blocked or Leaky Ductwork
Even if your AC is running correctly, cool air won’t reach your rooms if your ducts are blocked or leaking. Gaps or holes in the ductwork can lead to a loss of cooled air before it reaches your living space.
Signs of Ductwork Issues:
- Uneven cooling in different rooms.
- Higher-than-normal energy bills.
- Dust buildup around vents.
When to Call an Expert: A professional HVAC technician can inspect your ductwork for leaks, blockages, and insulation issues, ensuring maximum cooling efficiency.
When to Call a Professional for AC Repairs?
While some minor AC issues can be fixed with basic troubleshooting, there are times when professional intervention is necessary. If your AC is still not cooling after trying these solutions, it’s best to contact a trusted heating and cooling contractor near you.
Call for AC Repair If:
- Your AC runs but doesn’t cool your home at all.
- You hear strange noises such as grinding, hissing, or banging.
- There’s a persistent burning or musty smell coming from the vents.
- Your energy bills have skyrocketed without a clear reason.
- The system cycles on and off frequently or doesn’t turn on at all.
