Hey, it’s Jake—let’s beat the heat 😎❄️
Nothing’s worse than turning on your Amana 11,800 BTU through-the-wall AC and realizing it’s blowing warm air. Don’t panic! I’ve seen this hundreds of times, and most issues are fixable with a little elbow grease, some smart troubleshooting, and a bit of patience.
Let’s walk through the top cooling problems and how to fix them—Jake style.
1. Check the Thermostat and Settings
First things first: make sure the AC is set correctly.
-
Ensure it’s in cool mode and not fan-only.
-
Check the temperature setting—don’t set it below 68°F and expect miracles!
-
Verify the fan speed—sometimes low speed doesn’t circulate air well.
Pro tip: If your unit has a remote control, check the battery and settings before assuming the AC itself is broken. Sometimes it’s just a communication issue.
2. Inspect and Clean the Air Filter
A clogged filter is one of the most common causes of poor cooling.
-
Remove the front panel and pull out the filter.
-
Wash with warm water and mild detergent if needed.
-
Let it dry completely before reinstalling.
Jake hack: Clean it monthly during peak season to avoid airflow problems. More tips on AC maintenance are in this Homes & Gardens guide.
3. Check for Obstructed Airflow
Make sure nothing is blocking the front or back of the unit.
-
Furniture or curtains in front of the AC? Move them.
-
Outdoor unit blocked? Clear leaves, plants, or debris around it.
Blocked airflow makes the compressor work harder, reducing cooling efficiency and increasing wear.
4. Inspect the Condenser and Coils
Dirty condenser coils reduce cooling power.
-
Turn off the AC and remove the front panel.
-
Gently vacuum or brush the coils to remove dust and dirt.
-
Make sure the coil fins aren’t bent—use a fin comb if needed.
Jake tip: Annual coil cleaning can prevent most cooling complaints. For a full maintenance walkthrough, check Energy.gov’s AC guide.
5. Check the Drain Line
If the unit detects water buildup, some models automatically stop cooling to prevent leaks.
-
Inspect the drain line for clogs.
-
Use a pipe cleaner or mild vinegar solution to clear obstructions.
A clear drain line ensures your AC can operate at full power without interruptions.
6. Listen for Unusual Noises
Rattles, hissing, or squealing could indicate mechanical issues affecting cooling.
-
Loose screws or panels can create vibration—tighten them.
-
Fan or compressor issues may require professional service.

7. Reset the Unit
Sometimes, a simple reset can fix minor electronic glitches:
-
Turn off the unit and the breaker.
-
Wait 5–10 minutes.
-
Turn the breaker and AC back on.
Jake tip: Treat this like your “AC coffee break”—it gives the electronics a chance to recalibrate.
8. Professional Help When Needed
If you’ve tried everything and your AC still isn’t cooling properly, it might be time to call in a pro:
-
Electrical issues or blown fuses
-
Refrigerant leaks
-
Compressor or motor failure
A certified technician can safely handle these problems without risk.
