Your Essential Guide to Buying a Through-the-Wall Air Conditioner
Through-the-wall air conditioners offer a neat way to cool a room. They fit right into a hole in your wall. This means no window space is taken up. They are often quieter than window units. This guide helps you pick the best one for your needs.
Key Features to Look For
When shopping, keep these important features in mind. They make a big difference in how well the AC works for you.
- **Cooling Capacity (BTUs):** This is how much cooling power the unit has. You need the right size for your room. Too small, and it won’t cool well. Too big, and it wastes energy. Check the square footage of your room first.
- **Energy Efficiency (SEER Rating):** Look for a high Seasonal Energy Efficiency Ratio (SEER). A higher number means the unit uses less electricity to cool. This saves you money on power bills.
- **Noise Level (Decibels):** Since these units are in your wall, quiet operation is important. Lower decibel (dB) ratings mean quieter cooling. This is great for bedrooms or offices.
- **Smart Features:** Many modern units have Wi-Fi control. You can adjust the temperature from your phone. Some also have sleep modes or programmable timers.
- **Air Filtration:** Good filters keep dust and allergens out of your room. Look for washable or easily replaceable filters.
Important Materials in Construction
The quality of materials affects how long your AC lasts.
The outer casing is usually durable plastic or painted metal. Metal resists dents better. Inside, the coils are key. Copper coils transfer heat very well. Aluminum coils are cheaper but might not last as long. Look for units with corrosion-resistant coatings, especially if you live near the coast.
Factors That Improve or Reduce Quality
Good design makes for a better AC. Poor design leads to problems later.
Improving Quality:
- **Sturdy Frame:** A solid metal frame keeps the unit steady in the wall. This reduces rattling noises.
- **Inverter Technology:** Inverter compressors adjust their speed instead of just turning fully on or off. This keeps the temperature steady and saves energy.
- **Easy Access Panels:** If you can easily reach the filter and coils for cleaning, you will maintain the unit better. Good maintenance improves performance.
Reducing Quality:
- **Thin Plastic Housings:** These can crack or become brittle over time with sun exposure.
- **Basic On/Off Compressors:** These cycle on and off frequently. This uses more power and causes temperature swings.
- **Poorly Sealed Vents:** Gaps around the vents let outside air leak in, making the unit work harder.
User Experience and Use Cases
Through-the-wall ACs shine in specific situations.
They are perfect for apartments or condos where window units are not allowed. They also work well in additions or sunrooms where you need dedicated cooling. Users often praise how clean they look compared to window units. Installation is permanent, so it requires cutting a hole in the exterior wall. This usually means professional help is needed.
For a bedroom, prioritize low noise (under 50 dB). For a living room, focus on high cooling capacity and smart controls so you can manage it from the couch. Remember, these units vent heat directly outside through the back, so make sure the exterior wall area is clear.
Through-the-Wall Air Conditioner: Top 10 FAQs
Q: What is the main difference between this and a window AC?
A: A through-the-wall unit is permanently installed in a hole in the wall. A window unit sits in the window frame and takes up window space.
Q: Do I need professional installation?
A: Yes, almost always. You must cut a precise, framed opening in an exterior wall. This requires carpentry and electrical knowledge.
Q: How much electricity do they use?
A: It depends on the size (BTUs) and the SEER rating. A high SEER unit uses much less electricity than an old, low SEER unit.
Q: Can I install this unit myself?
A: While some handy people try, it is not recommended. Incorrect installation can lead to leaks, poor efficiency, or structural issues.
Q: Are they louder than mini-splits?
A: Generally, yes. Through-the-wall units have the compressor outside, but the fan and mechanics are all inside the room. Mini-splits keep the noisy parts entirely outside.
Q: What is a “sleeve”?
A: The sleeve is the metal housing that slides into the wall opening. The AC unit slides into this sleeve. You must buy the correct sleeve for your specific AC model.
Q: How often should I clean the filter?
A: You should check the filter monthly during heavy use seasons. Wash or replace it when it looks dusty to keep the air clean and the AC running efficiently.
Q: Can I use this to heat my room too?
A: Some models are “heat pump” versions. These can provide both cooling in summer and heat in winter. Check the product description for heating capability.
Q: What happens if I move? Can I take it with me?
A: No. Since these are permanently installed into the structure of the house, you leave the unit behind when you move.
Q: Will this unit fit in any wall opening?
A: No. Standard sizes exist, but you must measure the existing opening or plan the new opening based on the exact dimensions of the unit and its required sleeve.
