Hey There! Tony Here!
A reliable air conditioner is essential for keeping your home comfortable, especially in the summer. But even dependable models like the Amana 11,800 BTU Through-the-Wall AC can occasionally run into issues. The good news? Many of these problems are common and can be solved with a little patience and the right approach.
In this guide, I’ll walk you through the most frequent AC issues, how to identify them, and practical fixes you can try before calling a professional.
1. AC Isn’t Cooling Properly
If your Amana isn’t cooling as expected, check the following:
-
Air Filter: A dirty or clogged filter restricts airflow. Clean or replace it every 1–2 months. According to the U.S. Department of Energy, a clean filter can improve efficiency by up to 15%.
-
Thermostat Settings: Ensure it’s set to “cool” and at your desired temperature.
-
Obstructions: Check that the vents aren’t blocked by furniture or curtains.
If it’s still not cooling, the unit might need refrigerant service from a licensed technician.
2. Strange Noises or Vibrations
Your AC should run relatively quietly. If you hear rattling, buzzing, or grinding:
-
Loose Screws: Inspect the mounting and tighten any that have come loose.
-
Debris in the Unit: Sometimes leaves or dirt get inside and cause rattling.
-
Fan Issues: A bent fan blade can cause noise and vibration.
For persistent noises, it may be best to call a professional, as it could indicate a motor or compressor problem. Check resources like HomeTips for deeper DIY repair insights.
3. Water Leaks or Moisture Around the Unit
Seeing water where it shouldn’t be? Common culprits include:
-
Blocked Drain Line: Clear out any clogs to allow proper drainage.
-
Improper Installation: The unit should be slightly tilted to let condensation flow out.
-
High Humidity: Extra condensation is normal during humid days, but puddles aren’t.

4. Unit Won’t Turn On
If pressing the power button does nothing:
-
Check Power Supply: Ensure the AC is plugged in and the outlet works.
-
Circuit Breaker: Reset it if it’s tripped.
-
Remote Batteries: Swap them out—sometimes it’s the simplest fix.
If the unit still doesn’t power on, the internal fuse or control board may be the issue, requiring professional service.
5. Weak Airflow
If cool air is coming out but not strongly enough to reach across the room:
-
Filter & Coils: Dirty coils reduce airflow. The EPA recommends routine cleaning to improve indoor air quality and system performance.
-
Fan Speed: Double-check the remote settings.
-
Obstructions: Ensure there’s at least 2–3 feet of clearance around the unit for ventilation.
Weak airflow that persists after cleaning could point to blower or motor issues.
