🧊 Introduction: Choosing the Right Cooling Solution
If you’re deciding between a through-the-wall air conditioner like the GE 12,000 BTU AKEQ12DCJ and a window air conditioner, it’s critical to understand which system will serve your small space best while maintaining energy efficiency, ease of use, and comfort.
Tony, a practical HVAC technician, says:
“It’s not just about cooling; it’s about what fits your lifestyle, your windows, and your walls.”
This guide will help you make an informed decision by comparing:
-
Installation
-
Energy efficiency
-
Cost
-
Noise levels
-
Aesthetics
-
Heating options
🛠️ Installation: Permanent vs. Temporary
Through-the-Wall AC:
-
Installed directly into an exterior wall.
-
Requires a wall sleeve for support and stability.
-
Permanent installation; frees your windows.
-
Requires cutting into the wall and potential electrical updates (208/230V units).
Window AC:
-
Mounted in a window opening.
-
Easy to install and remove seasonally.
-
Can block natural light and window views.
-
Uses standard 115V outlets.

⚡ Energy Efficiency
Both AC types can be energy efficient if sized properly.
-
Through-the-wall ACs often have higher CEER ratings due to better sealing.
-
Window ACs may leak air around seals if not installed correctly.
-
Units with programmable thermostats, sleep modes, and energy-saving modes save additional energy.

💰 Cost Comparison
| Feature | Through-the-Wall AC | Window AC |
|---|---|---|
| Unit Cost | $$–$$$ | $–$$ |
| Installation | $$ | $ |
| Maintenance | $$ | $ |
| Energy Cost | Similar if sized properly | Similar |
-
Through-the-wall ACs have higher upfront and installation costs but can last longer with fewer seasonal issues.
-
Window ACs are cheaper to purchase and install but may require seasonal removal and reinstallation.
🔊 Noise Levels
-
Through-the-wall units often run quieter as the wall absorbs some operational noise.
-
Window ACs may vibrate against the window frame and amplify sound.
If noise sensitivity is a concern, verify decibel ratings (ideally under 60 dB for bedrooms).
🖼️ Aesthetics and Space Use
Through-the-Wall AC:
-
Frees up window space for light and views.
-
Provides a clean, built-in appearance.
-
No need to remove for winter.
Window AC:
-
Takes up window space and can block views.
-
Visibly protrudes outside the home.
-
Typically removed during off-season to prevent drafts and damage.
🌡️ Heating Capabilities
Many through-the-wall ACs include electric heat (like the GE 12,000 BTU model), making them useful year-round for supplemental heating.
While some window ACs also feature heat, they typically provide lower heating capacity.

🧩 Best Applications for Each System
✅ Through-the-Wall AC is ideal if:
-
You own your home or have landlord approval.
-
You want a permanent solution with heating options.
-
You want to keep your windows clear for light and ventilation.
-
You can invest in professional installation.
✅ Window AC is ideal if:
-
You rent or cannot modify walls.
-
You want low upfront costs.
-
You need seasonal flexibility.
-
You need to cool a small space quickly with minimal investment.
🛠️ Maintenance Considerations
Both types require:
-
Regular filter cleaning.
-
Coil cleaning.
-
Checking for drainage blockages.
Through-the-wall ACs may require periodic resealing around the sleeve to prevent air leaks, while window units may require reinstalling seals each season.

✅ Conclusion: Which Should You Choose?
-
If you prioritize permanent installation, supplemental heat, and clear windows, a through-the-wall AC is the better investment.
-
If you need affordability, ease of installation, and seasonal flexibility, a window AC may be your best choice.
Tony’s Tip:
“If you plan to stay in your home long-term and want a clean look without blocking your windows, go through-the-wall. If you’re renting or on a tight budget, stick with a window unit.”
If you need personalized sizing or compatibility checks for your space, consult your local HVAC expert or The Furnace Outlet’s support team before purchasing.
