When I replaced my bulky window unit with an Amana 11,800 BTU Through-the-Wall Air Conditioner, I didn’t just want colder air — I wanted peace and quiet. I wanted my room to feel open, uncluttered, and comfortable year-round without the constant hum of machinery or a half-blocked window view.
The surprise? Installing an in-wall AC didn’t just improve my cooling — it transformed my living space.
If you’ve ever wondered how an in-wall system looks, sounds, and fits into your home’s aesthetic, here’s what you can expect (and how to make the most of it).
🔇 1. Understanding Noise Levels — How Quiet Is “Quiet”?
The first question every homeowner asks: “How loud will it be?”
Through-the-wall units, unlike window ACs, are designed for permanent installation and better insulation — meaning less vibration, fewer rattles, and quieter operation.
Noise in air conditioners is measured in decibels (dB). Every increase of 10 dB roughly doubles the perceived loudness.
Here’s how common sounds compare:
| Sound Source | Approx. dB | Perceived Loudness |
|---|---|---|
| Whisper | 30 dB | Almost silent |
| Refrigerator hum | 40 dB | Soft background |
| Amana 11,800 BTU (Low Fan) | 54–56 dB | Gentle hum |
| Conversation | 60 dB | Noticeable |
| Window AC (average) | 65–70 dB | Clearly audible |
That means the Amana operates quieter than most standard window models — about the sound level of a modern dishwasher or light rainfall.
When you’re watching TV or working, it blends into the background — consistent, calm, and reliable.

🧱 2. Why In-Wall Installation Is Naturally Quieter
There’s a reason wall units like Amana’s feel calmer than their window counterparts — it comes down to placement and design.
When mounted into a solid wall with a sleeve enclosure, much of the compressor’s vibration and motor noise stays outside.
The wall itself acts as a natural sound barrier.
Three noise-dampening features built into wall installs:
-
The wall’s thickness blocks direct sound transmission.
-
Insulated sleeves absorb vibration between the unit and framing.
-
Exterior extension keeps the loudest components outdoors.
So instead of that sharp, metallic buzz that window ACs often have, you get a steady, softened hum that’s easy to live with.
“It’s the difference between hearing the AC and feeling the comfort.”

📏 3. Space Planning — How Much Room Does It Really Take?
An in-wall unit may sound intrusive, but in reality, it’s far more space-efficient than any portable or window AC.
A standard Amana wall sleeve measures about 26 inches wide × 15.5 inches high × 16–18 inches deep. The faceplate sits nearly flush with the interior wall, while the body extends through to the exterior.
| Component | Dimensions (inches) | Placement |
|---|---|---|
| Wall Opening | 26” × 15.5” | Framed cutout |
| Sleeve Depth | 16–18” | Inside wall cavity |
| Clearance | 3–6” | For air circulation |
Optimal placement tips:
-
Install at 24–36 inches from the floor for even air distribution.
-
Keep 3 ft. clearance around the unit — no furniture, drapes, or artwork directly in front.
-
Position on an exterior-facing wall to vent heat efficiently.
I chose the long wall in my living room — centered between two shelves — and it looks intentionally built in rather than “added on.”
🪟 4. Space Comparison — Wall Unit vs. Window AC vs. Mini Split
Here’s how different systems stack up when it comes to footprint, visibility, and sound:
| System Type | Space Impact | Visibility | Noise Level | Installation |
|---|---|---|---|---|
| Through-the-Wall (Amana) | Moderate | Discreet | ★★★★☆ (Quiet) | Permanent |
| Window AC | Blocks window | High | ★★☆☆☆ (Loud) | Semi-permanent |
| Mini Split | Wall mount + line set | Visible | ★★★★★ (Very Quiet) | Professional |
The big difference?
-
A window AC is temporary and clunky.
-
A mini split is whisper-quiet but requires professional installation.
-
A through-the-wall system balances affordability, performance, and aesthetics — a “set it and forget it” solution for long-term cooling.

🎨 5. Aesthetics That Blend — Design Integration
For many homeowners (myself included), this part matters almost as much as the cooling.
The Amana 11,800 BTU model is designed to disappear into your décor — with neutral white and gray tones, clean grille lines, and a subtle LED display.
Easy ways to make your in-wall AC look intentional:
-
Paint the grille frame to match your wall color.
-
Add wood trim or molding around the unit for a built-in appearance.
-
Symmetry matters: center the AC between furniture or wall art.
-
Hide the cord using cord covers or baseboard channels.
Even better, through-the-wall installation keeps your windows unobstructed — meaning natural light stays, and your room feels larger.

🌬️ 6. Airflow & Comfort Zones
The Amana’s adjustable louvers give you control over airflow direction, allowing both horizontal sweep and vertical tilt.
That means you can:
-
Point cool air across the room, not directly at seating.
-
Create even temperature balance in open spaces.
-
Avoid cold spots in corners or near walls.
For best results, angle vents toward open floor space or the center of the room — never toward drapes or wall corners that block circulation.

🔧 7. Common Noise & Space Mistakes (and How to Fix Them)
Even a high-quality system like Amana’s can make extra noise if installed incorrectly or neglected.
| Issue | Cause | Quick Fix |
|---|---|---|
| Rattling sound | Loose screws or wall sleeve gaps | Tighten fasteners; add foam strips |
| Humming or buzzing | Fan imbalance or dirty coils | Clean filter; vacuum coils |
| Whistling | Air leak around sleeve | Reseal with weatherproof caulk |
| Vibration noise | Wood framing resonance | Add rubber vibration pads |
| Weak airflow | Blocked vent or dirty filter | Move furniture; clean filter monthly |
Pro tip: Always use a level during installation — even a slight tilt can cause water pooling or noise from the drain pan.

💡 8. Samantha’s Quiet Home Setup Tips
After a few months with my Amana, here’s what I’ve learned:
-
Choose placement wisely.
Installing it in the living room wall (instead of near the bedroom) keeps nighttime noise minimal. -
Add vibration-dampening foam.
It costs under $10 and cuts down resonance dramatically. -
Clean your filter monthly.
A dusty filter forces the fan to work harder — and louder. -
Don’t push furniture right up against it.
Air needs space to move. I leave at least a two-foot gap. -
Decorate around, not over.
Hanging light curtains nearby helps it blend visually without blocking vents.
“I used to turn my old AC off to make phone calls. Now, I can barely tell when my Amana’s running.”
🔋 9. Maintenance = Consistent Quiet
Noise often sneaks up on homeowners — not because the system “gets louder,” but because maintenance slips.
Routine checklist:
-
Monthly: Remove and rinse air filter.
-
Seasonally: Vacuum dust from coils and interior grilles.
-
Annually: Check wall sleeve for cracks, corrosion, or insulation wear.
-
After heavy rain: Inspect exterior vent for debris or buildup.
Even a small dust layer can increase noise by 2–4 dB. Preventive care is your best friend for long-term silence.

🧠 10. How Noise Evolves Over Time
A well-maintained Amana wall unit should stay quiet throughout its lifespan. But here’s how performance typically shifts depending on care:
| Condition | Noise Level (dB) | Performance | Comfort |
|---|---|---|---|
| New installation | 54–56 | Peak | Whisper-quiet |
| Dirty filter | 58–60 | Slightly reduced | Noticeable hum |
| Loose sleeve | 62+ | Reduced | Audible vibration |
| Post-maintenance | 54 | Restored | Silent comfort |
Keeping your AC tuned means keeping your peace intact.

🪴 11. The Aesthetic Advantage — Living Space That Breathes
Wall units aren’t just practical — they improve how your room feels.
Here’s why:
-
You regain window space and light.
-
The design blends into your architecture.
-
It feels like part of the wall, not a machine in your room.
Adding a few décor touches can elevate it further:
-
Frame it with matching trim.
-
Use wall colors that complement the grille.
-
Balance the space with a plant or artwork on the opposite wall.
“It’s subtle, it’s modern, and it’s mine — exactly how home comfort should feel.”
🏁 12. Final Takeaway — Quiet Comfort Meets Clean Design
Through-the-wall systems like the Amana 11,800 BTU deliver more than powerful cooling — they bring harmony to your space.
They’re quieter, sleeker, and smarter in how they integrate with your life.
Here’s what to remember:
-
Noise: Expect 54–56 dB — quieter than most window units.
-
Space: Minimal footprint; frees up your windows.
-
Aesthetics: Designed to blend with modern interiors.
-
Maintenance: The key to keeping things peaceful.
If you’re ready to move beyond the rattle and clutter of a window AC, an Amana through-the-wall setup might just be your next upgrade in comfort, calm, and style.
