Hey There, Mike Here!
Your Amana 11,800 BTU through-the-wall AC is designed for long-lasting performance, but like any appliance, there comes a point when DIY fixes aren’t enough. Knowing when to pick up the phone and call a licensed HVAC technician can save you time, money, and frustration—not to mention help keep your home cool and comfortable.
In this guide, we’ll walk through the warning signs that your AC needs professional attention, why delaying repairs can make things worse, and how to choose the right service for your unit.
🔧 Signs You Should Call a Pro
1. Strange Noises and Vibrations
If you start hearing grinding, rattling, or buzzing, it’s a red flag. These sounds could point to loose components, worn-out fan blades, or even failing motors. Unlike minor filter changes, these issues often require a trained hand.

2. Weak or Uneven Cooling
If your Amana unit struggles to keep the room at your desired temperature—or one side of the space is cooler than the other—your AC may be battling a refrigerant leak or compressor problem. Both are serious mechanical issues that need a technician.

3. Frequent Cycling or Constant Running
Does your AC turn on and off too often, or run constantly without ever hitting the right temperature? That’s a sign of faulty thermostats, clogged coils, or electrical issues. These aren’t problems you can solve with a simple filter swap.

4. Water Leaks or Excess Moisture
Through-the-wall ACs naturally produce condensation, but pools of water inside your room or around the wall opening are never normal. Left unchecked, moisture can damage walls and flooring—or lead to mold. A professional can clear the drain lines and fix the root issue.

5. Spiking Energy Bills
A sudden increase in your utility bill—without a change in usage—often means your AC is working harder than it should. Dirty coils, refrigerant loss, or failing motors can all drain efficiency. Only a pro can properly diagnose and fix the source.

🛠 Why DIY Fixes Aren’t Always Enough
Yes, homeowners can (and should) handle basics like cleaning filters, checking vents, and removing obstructions. But electrical repairs, refrigerant handling, and sealed-system work require EPA-certified technicians. Attempting these fixes yourself could:
-
Void your warranty
-
Cause more damage to the unit
-
Pose safety hazards to you and your home
🌟 When in Doubt, Call a Professional
If you’re experiencing any of the signs above, it’s time to schedule an inspection with a qualified HVAC technician. The sooner you act, the less likely you are to face costly breakdowns—or worse, a complete replacement.
Your Amana 11,800 BTU through-the-wall AC is an investment in comfort. Protect it by knowing when to call in the experts.
