When you’re trying to stay cool in the summer, choosing the right air conditioner is about more than BTUs or brand names — it’s about long-term comfort.
Two of the most popular options for single-room cooling are through-the-wall air conditioners and window air conditioners. Both deliver powerful cooling, but they differ in installation style, durability, energy efficiency, and long-term performance.
As a homeowner, I (Samantha Reyes) faced the same dilemma last year — do I keep using a window unit or invest in a more permanent wall-mounted system like the Amana 11,800 BTU 115V Through-the-Wall Air Conditioner with Remote?
Here’s what I learned — and what every homeowner should know before deciding.
🏠 1. The Comfort Dilemma: Choosing the Right Type for Your Space
If you’ve ever lugged a window AC in and out each summer, you know the struggle.
At first, it seems convenient — install it in May, store it by October — but over time, the seasonal wear, rattling noise, and window drafts start to add up.
That’s why many homeowners are switching to through-the-wall systems like Amana’s 11,800 BTU model. These units are built for permanence, designed to fit inside an insulated wall sleeve and stay there year-round.
“I wanted a cleaner, quieter solution that didn’t block my window light — and I didn’t want to keep reinstalling it every season.”
Both system types can cool similar-sized rooms, but the long-term comfort, cost, and performance can vary dramatically.
⚙️ 2. What’s the Difference Between Through-the-Wall and Window ACs?
At first glance, the two look similar — box-shaped units that draw in warm air and expel cool air. But their installation method and design focus set them apart.
| Feature | 🧱 Through-the-Wall AC | 🪟 Window AC |
|---|---|---|
| Installation | Built into wall with a sleeve (permanent) | Placed in window frame (temporary) |
| Appearance | Seamless, doesn’t block window | Partially blocks light/view |
| Energy Efficiency | Better sealing, less air leakage | Can leak air around window gaps |
| Noise Level | Quieter (sound isolated by wall) | Louder (vibrations on glass) |
| Security | Fixed in place, harder to remove | Easier to remove from outside |
| Maintenance | Simple, long-term access | Must remove to deep clean |
A through-the-wall unit is ideal if you want permanent comfort, quieter operation, and better energy control. A window unit suits renters or those needing a seasonal, portable option.

🔇 3. Noise & Comfort: Why Wall Units Are Quieter
Noise can be a dealbreaker — especially in bedrooms or home offices.
Through-the-wall ACs win here for a few reasons:
-
The compressor and fan assembly sit behind a thick wall, not against thin glass.
-
Fewer vibration points — wall sleeves absorb sound instead of amplifying it.
-
Many models, like Amana’s, include multi-speed fans for whisper-quiet night modes.
By contrast, window units vibrate within a flexible frame, causing that familiar humming or rattling sound when the compressor cycles.
Typical noise levels:
| AC Type | Average dB (decibels) | Sound Level Equivalent |
|---|---|---|
| Through-the-Wall | 50–56 dB | Quiet conversation |
| Window | 58–65 dB | Background chatter / TV volume |
So, if your goal is peaceful cooling, especially for sleep, a wall unit easily wins the comfort test.

⚡ 4. Energy Efficiency: Small Seals, Big Savings
Did you know that poor sealing around a window unit can waste up to 30% of your cooling energy?
That’s because window frames flex with temperature, allowing warm air in and cool air out.
Through-the-wall systems are better insulated, sitting flush with the wall sleeve. This reduces leaks and keeps your thermostat stable.
🔋 Efficiency Ratings to Know:
-
EER (Energy Efficiency Ratio) – Measures cooling output per watt.
-
CEER (Combined Energy Efficiency Ratio) – A newer, more accurate standard that includes standby power usage.
Many through-the-wall models, like Amana’s 11,800 BTU unit, feature high CEER ratings, meaning they deliver consistent cooling for less energy.
You can save $20–$40 per month in electricity costs compared to a typical window AC, especially in humid climates.

🧱 5. Installation & Space: One and Done vs. Seasonal Setup
One of the biggest differences between the two systems is how you install them.
🧱 Through-the-Wall:
-
Requires cutting a hole in an exterior wall and adding a metal wall sleeve (sold separately).
-
Once installed, it’s permanent — no seasonal removal.
-
Great for homeowners or long-term residents.
-
Keeps windows clear and aesthetically clean.
🪟 Window:
-
Simple installation — fits into existing window frames.
-
Must be removed every winter (for insulation and safety).
-
May require extra sealing foam to prevent drafts.
-
Reduces window light and can compromise view.
| Cost Breakdown | Through-the-Wall | Window |
|---|---|---|
| Upfront Equipment | $$ | $ |
| Installation Labor | $$ (one-time) | $ |
| Seasonal Setup | None | Annual |
| Aesthetic Impact | 👍 Permanent | 👎 Blocks window |
So, while the initial install of a wall unit takes more effort, it pays off with years of convenience.

💰 6. Long-Term Cost of Ownership
Let’s talk dollars and sense.
A through-the-wall AC can last up to 15 years, while a window unit often lasts 5–8 years before efficiency drops or parts fail.
📊 Average Ownership Costs Over 10 Years
| Category | Through-the-Wall | Window Unit |
|---|---|---|
| Initial Cost | $700–$1,000 | $250–$500 |
| Installation | $200–$400 | Minimal |
| Maintenance | Low (washable filter) | Moderate |
| Annual Energy Use | Lower (better sealing) | Higher |
| Expected Lifespan | 10–15 years | 5–8 years |
| Estimated 10-Year Total | ~$1,400 | ~$1,200–$1,400 |
Even though both may cost similar over a decade, through-the-wall systems maintain better comfort and resale appeal.

🧼 8. Maintenance Made Simple
Maintaining your air conditioner properly is key to keeping energy bills low and air quality high.
Through-the-wall systems are easier to maintain because their design is semi-permanent and accessible.
🧱 Through-the-Wall Maintenance
-
Washable filters slide out from the front panel.
-
Drainage system protected by wall sleeve.
-
Coils less exposed to dirt and debris.
-
No need to remove the unit for deep cleaning.
🪟 Window Unit Maintenance
-
Must be taken out for coil cleaning.
-
Exposed to outdoor moisture (risk of corrosion).
-
Seals wear down quickly, causing leaks.
-
More prone to mold growth in humid regions.
💡 Seasonal Tip: Clean filters every 30–45 days for best airflow and to reduce energy consumption by up to 15%.

🌿 9. Design & Environmental Considerations
While it’s not the first factor most people think about, design and environmental impact play a big role in long-term satisfaction.
Through-the-wall ACs are built to last — fewer replacements mean less landfill waste.
They also have cleaner, low-profile fronts that blend into your décor without blocking sunlight.
Window units, while inexpensive, often end up in landfills after only a few years due to corrosion, broken seals, or mechanical wear.
Many modern wall ACs now use R-32 refrigerant, which has a lower global warming potential (GWP) than older R-410A systems, reducing environmental impact.
