Essential Factors to Consider When Selecting Your Ideal Through-the-Wall Air Conditioner
- Cooling Capacity (BTUs): Look for the British Thermal Units (BTUs) rating to determine the unit’s cooling capacity. A higher BTU rating means more cooling power, but it’s important to choose a unit that matches the size of your room. Generally, you’ll want about 20 BTUs per square foot of living space
- Energy Efficiency: Check the Energy Efficiency Ratio (EER) or the Seasonal Energy Efficiency Ratio (SEER). The higher the rating, the more efficient the unit will be, which can save you money on energy bills. Look for ENERGY STAR certified models for better efficiency
- Noise Level: Look at the decibel (dB) rating of the air conditioner. A quieter unit will make your space more comfortable, especially if you plan to use it while sleeping or during quiet activities. Aim for models with a lower dB rating for a more peaceful environment
Step-by-Step Guide to Installing and Operating Your Through-the-Wall Air Conditioner
- Install Properly: Make sure your air conditioner is installed securely in a wall sleeve, ensuring that it’s level and that any insulation is properly placed to prevent air leaks. This will help it run efficiently and effectively
- Set the Temperature: Use the thermostat to select your desired temperature. Start with a moderate setting and adjust as needed. Most units have a “cool” mode for hot days and a “fan” mode for circulating air without cooling
- Regular Maintenance: Clean or replace air filters regularly (usually every month) to keep your unit running smoothly. Also, check the exterior for debris and ensure the drainage system is clear to prevent water build-up
- These tips will help you get the most out of your through-the-wall air conditioner! Enjoy your cool space!

I have to say, I really love my Midea 8000 BTU 3-in-1 AC Unit! It’s so versatile with the heating and fan options. Plus, it doesn’t take up much space at all. It’s been a lifesaver during the heatwaves this summer. How do you think it stacks up against the other LG options?
Great to hear you love the Midea! It’s definitely a compact and efficient choice. The LG units are often praised for their durability and cooling power, but the Midea’s 3-in-1 functionality is a huge plus, especially for smaller spaces. Each has its strengths, so it really comes down to what features matter most to you!
Thanks for the list! I was wondering if you could dive a bit deeper into the noise levels of these units? I’ve heard mixed reviews about certain models being a bit loud, which is a dealbreaker for me when I’m trying to sleep. Would love your insights on that!
Absolutely, I totally get your concern about noise levels! The LG units tend to be on the quieter side, while the OLMO models might have a bit more sound output, especially on higher settings. I’ll look into providing more detailed info on noise levels in future posts. Thanks for the suggestion!
