What to Look for Before Buying the Best Through The Wall Air Conditioners
Choosing the right through-the-wall AC unit is a long-term investment in your comfort. To ensure you make the best choice, consider these crucial factors before making a purchase.
Find Your Need - Compatibility and use case considerations
First, measure the existing wall sleeve if you have one. Through-the-wall units come in standard sizes, but it’s essential to verify the height, width, and depth to ensure a proper fit. If you’re creating a new opening, you have more flexibility but should still choose a standard size for future replacement ease. Next, calculate the cooling power (BTU) you need. A unit that is too small will struggle to cool the room, while one that is too large will cycle on and off too frequently, failing to dehumidify the air properly. A general rule is 20 BTUs per square foot of living space. For a 400 sq. ft. room, you would look for an 8,000 BTU unit.
Budget - Setting realistic price expectations ($450-$900 ranges)
Through-the-wall air conditioners typically range in price from around $450 for basic, smaller models to over $900 for powerful, feature-rich units with heating and smart capabilities. Set a realistic budget based on your needs. A standard 8,000-10,000 BTU cooling-only unit from a reputable brand will likely fall in the $500-$700 range. If you want advanced features like inverter technology, Wi-Fi control, or a heating function, expect to be at the higher end of that spectrum. Remember to also factor in the potential cost of professional installation if you’re not comfortable doing it yourself.
Key Features - Most important technical specifications
Beyond BTU, look at the Energy Efficiency Ratio (EER). A higher EER means the unit is more efficient and will cost less to run. Look for models with an EER of 10.0 or higher. Consider the control options: do you want a simple digital panel, a convenient remote control, or the advanced flexibility of Wi-Fi and voice control? Also, check for different operating modes like Energy Saver, Sleep Mode, Dehumidify, and a programmable timer. These features add significant convenience and can help reduce energy consumption.
Quality & Durability - What to look for in construction
A through-the-wall AC is a semi-permanent fixture, so durability is key. Look for units with a slide-out chassis, which makes installation and cleaning much easier. A washable and reusable filter is another must-have feature, as it saves you money on replacements and is better for the environment. Check user reviews for comments on the unit’s build quality, noise levels, and longevity. A solid, well-constructed unit will provide reliable cooling for many years.
Brand Reputation - Importance of established manufacturers
Stick with well-known, reputable brands like LG, Frigidaire, Whirlpool, and Midea. These companies have a long history of making reliable appliances and typically offer better customer support and warranty coverage. While a lesser-known brand might offer a lower price, it could come at the cost of reliability, performance, and access to replacement parts down the line. Investing in a trusted brand often provides peace of mind.
Portability/Size - Considerations for space and storage
While not portable, the size of the unit is a critical factor. Ensure the unit’s dimensions (width, height, and depth) will fit your wall opening or sleeve. The most common width is around 24 inches, but it’s crucial to measure precisely. Also, consider the unit’s weight, especially if you plan to install it yourself. These units can be heavy, and you may need assistance to lift it safely into place.
Is it A Wise Decision to Buy through the wall air conditioners?
Investing in a through-the-wall air conditioner is a very wise decision for homeowners seeking a permanent, efficient, and aesthetically pleasing cooling solution. Unlike window units, which block your view and can pose a security risk, through-the-wall models are securely installed, creating a weather-tight seal that prevents drafts and energy loss. This superior insulation leads to greater efficiency and lower utility bills over time compared to their window-mounted counterparts.
When compared to central air conditioning, a through-the-wall system offers significant cost savings, both in initial purchase price and installation. It also provides excellent zoned cooling, allowing you to cool specific rooms or areas without wasting energy on unoccupied parts of the house. This is particularly beneficial for larger homes or for supplementing a central system in a room that tends to get too hot, like an upstairs bedroom or a sunroom.
The long-term benefits are substantial. These units are built for durability and, with proper maintenance like regular filter cleaning, can last for a decade or more. They add value to your home by providing a built-in comfort feature. While the initial cost and installation may be higher than a portable or window AC, the superior performance, energy savings, and seamless integration make a through-the-wall air conditioner a smart and valuable home improvement investment.
What Is the Best Way to Choose through the wall air conditioners?
Choosing the best through-the-wall air conditioner involves a methodical approach to ensure you get the right unit for your specific needs. Follow this step-by-step guide for a confident purchase.
1. Measure and Assess Your Space: First, if you are replacing an old unit, carefully measure the existing wall sleeve’s height, width, and depth. This is the most critical step to ensure a new unit will fit. If you’re creating a new opening, decide on a location that allows for optimal airflow and is near an appropriate electrical outlet.
2. Calculate Your BTU Requirements: Determine the square footage of the room you want to cool (length x width). Use a BTU calculator or the general rule of 20 BTUs per square foot to find your target cooling power. Don’t oversize the unit; a properly sized AC is more effective and efficient.
3. Check Your Electrical Supply: Most units up to 12,000 BTUs run on a standard 115V outlet. However, more powerful models (typically 14,000 BTU and above) often require a 230V outlet. Check your available power source before you fall in love with a high-powered model you can’t use.
4. Compare Key Features and Efficiency: Look for a high Energy Efficiency Ratio (EER) to save on long-term running costs. Decide which features are most important to you: a remote control, a programmable timer, multiple fan speeds, energy-saving modes, or smart Wi-Fi controls. If you live in a climate with four distinct seasons, a unit with a supplemental heating function can provide excellent year-round value.
5. Read Reviews and Choose a Reputable Brand: Once you’ve narrowed down your options, read user reviews to get real-world feedback on performance, noise levels, and reliability. Sticking with trusted brands known for quality appliances is always a safe bet.
Common Mistakes to Avoid:
- Guessing the size: Never estimate your sleeve dimensions or room size. Always measure accurately.
- Ignoring the EER: A cheaper unit with a low EER will cost you more in electricity bills over its lifespan.
- Forgetting about maintenance: Choose a unit with an easily accessible, washable filter to ensure you can keep it running efficiently.
