This efficiency can lead to lower energy bills, especially during peak usage seasons.
- Space Saving: These units do not occupy window space, allowing for unobstructed views and natural light. This is particularly advantageous in smaller rooms or apartments, where maximizing available space is crucial.
- Noise Reduction: Through-wall units typically produce less noise than window-mounted air conditioners because the compressor is located outside the living space. This results in a quieter indoor environment, making it more comfortable for activities like sleeping or working.
- Security: Installing an air conditioner through the wall can enhance security compared to window units, which can be easily removed or damaged. A through-wall unit is fixed in place, making it more difficult for intruders to access your home through that opening.
- Consistent Temperature Control: These air conditioners provide more consistent temperature control throughout a room, as they are designed to cool or heat larger spaces effectively. This can lead to improved comfort levels, especially in larger rooms or open-concept layouts.
- Less Maintenance: Through-wall air conditioners often require less maintenance than window units, as they are designed for long-term use and have fewer components exposed to the elements. This can save time and effort in upkeep over the lifespan of the unit.
What Features Should You Consider When Choosing a Through-Wall Air Conditioner?
When choosing the best air conditioner through wall, it is essential to consider several key features to ensure efficiency and comfort.
- Cooling Capacity: The cooling capacity, measured in BTUs (British Thermal Units), determines how effectively the air conditioner can cool a space. It’s crucial to select a unit with the right BTU rating for the size of the room to avoid under or over-cooling, which can lead to discomfort and increased energy costs.
- Energy Efficiency Rating: The energy efficiency ratio (EER) or seasonal energy efficiency ratio (SEER) indicates how efficiently the unit operates. Higher ratings mean lower energy consumption, which can lead to significant savings on utility bills over time, making it an essential consideration for cost-conscious consumers.
- Noise Level: The noise level of a through-wall air conditioner can impact your comfort, especially in quiet environments. Look for units with a low decibel (dB) rating, as quieter models tend to provide a more pleasant indoor atmosphere, particularly during nighttime use.
- Installation Requirements: Different models may have various installation processes, including the need for additional framing or electrical work. It’s important to assess whether the installation requirements fit your capabilities and if professional installation is necessary, which can add to the overall cost.

How Do You Properly Install a Through-Wall Air Conditioner?
Properly installing a through-wall air conditioner involves several key steps to ensure optimal performance and efficiency.
- Choose the Right Location: Selecting a suitable location for your air conditioner is crucial. Ensure that the chosen wall is structurally sound, has access to electrical outlets, and allows for proper airflow without obstruction.
- Measure the Wall Opening: Accurate measurements are essential for a successful installation. You need to measure the height and width of the unit to cut the appropriate-sized opening in the wall, typically around 24 inches wide and 14 inches high.
- Cut the Wall Opening: Use a reciprocating saw or a jigsaw to cut the wall opening. Make sure to do this carefully to avoid damaging electrical wiring or plumbing that may be behind the wall.
- Install the Support Frame: A support frame is necessary to securely hold the air conditioner in place. This frame should be level and sufficiently sturdy to support the weight of the unit, helping to prevent any sagging over time.
- Insert the Air Conditioner: With the support frame in place, gently slide the air conditioner into the opening. Ensure that it is tilted slightly toward the outside to facilitate proper drainage of condensation.
- Seal the Edges: After positioning the unit, seal the edges with insulation foam or weather stripping. This helps to improve energy efficiency by preventing air leaks and keeping the unit anchored securely.
- Connect the Electrical Supply: Follow the manufacturer’s instructions to connect the electrical supply safely, ensuring that all wiring complies with local codes. If you’re unsure, it’s advisable to hire a licensed electrician to handle this step.
- Test the Air Conditioner: Once installed, turn on the air conditioner to test its functionality. Check that it cools the space effectively and that there are no unusual noises or leaks, indicating a successful installation.
What Maintenance Tips Will Help Extend the Life of Your Through-Wall Air Conditioner?
Maintaining a through-wall air conditioner properly can significantly extend its lifespan and improve its efficiency.
- Regular Cleaning of Filters: Clean or replace the air filters every month or as recommended by the manufacturer. Clogged filters can restrict airflow, causing the unit to work harder and potentially leading to overheating and breakdowns.
- Check and Clean the Condenser Coils: The condenser coils should be inspected and cleaned at least once a year. Dirty coils reduce the unit’s ability to cool effectively and can lead to increased energy consumption and wear on the compressor.
- Inspect and Seal the Installation Area: Ensure that the area around the unit is sealed properly to prevent air leaks. Gaps can allow outside air to enter, making the unit work harder to maintain the desired temperature and increasing energy costs.
- Drainage Maintenance: Make sure the condensate drain is clear and functioning correctly. A blocked drain can lead to water build-up, causing mold growth and potentially damaging the unit and surrounding areas.
- Seasonal Maintenance Checks: Before and after the cooling season, perform a thorough check of the unit. This includes testing the thermostat, checking refrigerant levels, and ensuring that all components are in good working order to prevent issues during peak usage times.
- Professional Servicing: Schedule professional maintenance at least once a year. A technician can identify and resolve issues that may not be apparent during regular inspections, ensuring the unit operates efficiently.
- Avoid Obstructions: Keep the area around the air conditioner clear of furniture, curtains, and other obstructions. This ensures proper airflow and prevents the unit from overheating due to restricted air intake and exhaust.
