You can run mini split refrigerant lines in walls, but you need to be careful about a few things. First, make sure that the wall is thick enough to accommodate the lines. Second, be aware of any potential condensation issues.
Third, make sure that the wall is properly insulated. Finally, consult with a professional before attempting to do this yourself.
- Drill a hole in the wall where you want to run the refrigerant lines for your mini split system
- Run the suction line (larger diameter) through the hole and connect it to the outdoor unit
- Run the discharge line (smaller diameter) through the hole and connect it to the indoor unit
- Use wall straps or other fasteners to secure both lines in place so they don’t vibrate or move around too much
- Insulate both lines with foam pipe insulation to help prevent heat loss/gain and condensation from forming on the lines
Can You Run Mini Split Refrigerant Lines in Walls
Refrigerant lines for ductless mini splits are most commonly installed along the perimeter of a room, near the ceiling. While it is possible to run the lines through walls, this is generally not recommended. Running the lines through walls can create issues with air flow and can also make it more difficult to service the unit in the future.
What are the Benefits of Running Mini Split Refrigerant Lines in Walls
There are many benefits to running mini split refrigerant lines in walls, including:
1. Increased Efficiency: When compared to traditional methods of ducting, mini splits suffer far less heat loss thanks to their more direct routing. This can lead to significant energy savings, particularly in colder climates.
2. Improved Air Quality: Because there are no large ducts circulating air throughout your home, there is also no opportunity for dust or other particles to become trapped and circulated as well. This can help improve indoor air quality, especially for those with allergies or respiratory sensitivities. 3. Greater Flexibility: Mini split systems offer a much greater degree of installation flexibility than forced-air systems.
For example, they can be used in homes with multiple levels or in areas where adding ductwork would be impractical or impossible. 4. Enhanced Comfort: Not only do mini splits tend to be more efficient than traditional HVAC systems, but they also provide targeted heating and cooling that can better meet your specific needs and preferences. Additionally, many models come equipped with features like built-in air filtration and humidity control that further improve comfort levels indoors.
Are There Any Drawbacks to Running Mini Split Refrigerant Lines in Walls
Yes, there are a few drawbacks to running mini split refrigerant lines in walls. One is that it can be more difficult to properly insulate the lines, which can lead to heat loss and decreased efficiency. Additionally, if there is a leak in the line, it can be more difficult to locate and repair.
Finally, running the lines through walls may slightly decrease the overall capacity of the system.
Where To Mount a Mini Split Indoor Wall Hung Unit
Yes, you can run mini split refrigerant lines in walls, but there are a few things to keep in mind. First, the length of the line should be no more than 50 feet. Second, the line should be insulated with an R-value of at least 3.5.
Third, the wall thickness should be at least 4 inches. Finally, make sure that the area around the mini split is well ventilated so that the condenser can function properly.
