7 best smallest mini split air conditioner

The smallest mini-split air conditioner is a type of cooling and heating system designed for individual room or zone climate control. These systems are often referred to as "mini-splits" due to their compact size compared to traditional HVAC systems. Here's what you need to know about the smallest mini-split air conditioner:

  1. Split System: Mini-split air conditioners are a type of split system, meaning they consist of two main components: an indoor unit and an outdoor compressor/condenser unit. The indoor unit is installed inside the room, while the outdoor unit is placed outside the building.

  2. Cooling and Heating: Mini-split systems provide both cooling and heating capabilities. They use a refrigerant cycle to transfer heat from one location to another. In the summer, they extract heat from inside and release it outside to cool the room, and in the winter, they reverse this process to provide heating.

  3. Size and Capacity: The term "smallest mini-split" refers to the compact size of the indoor unit. These units are designed to be unobtrusive and take up minimal space on the wall or ceiling. They are ideal for small rooms, apartments, or areas with limited installation space.

  4. Zoning: Mini-split systems offer zoning capabilities, allowing you to control the temperature in individual rooms or zones independently. This is achieved by installing multiple indoor units connected to a single outdoor unit. Each indoor unit can have its own thermostat and settings.

  5. Energy Efficiency: Mini-split air conditioners are known for their energy efficiency.They often come with inverter technology, which adjusts the compressor's speed to maintain the desired temperature, reducing energy consumption.

  6. Installation: Installing a mini-split system typically requires professional installation. The indoor unit is mounted on the wall, floor, or ceiling, and the outdoor unit is placed outside. The two units are connected by refrigerant lines and electrical wiring.

  7. Remote Control: Many mini-split systems come with remote controls or can be controlled through smartphone apps, making it convenient to adjust the temperature and settings from a distance.

  8. Quiet Operation: Mini-split systems are designed to operate quietly, with indoor units producing minimal noise levels. This makes them suitable for bedrooms, living rooms, or any space where noise may be a concern.

  9. Home Kitchen Use: While mini-split air conditioners are more commonly associated with bedrooms, living rooms, and offices, they can also be installed in kitchens to maintain a comfortable temperature during cooking and meal preparation.

  10. Maintenance: Like all HVAC systems, mini-split air conditioners require regular maintenance to ensure optimal performance and efficiency. This includes cleaning or replacing filters and scheduling annual inspections.

When considering the smallest mini-split air conditioner for your home or specific room, it's essential to consult with an HVAC professional to determine the appropriate size and capacity needed for your space. Additionally, consider factors such as energy efficiency, installation requirements, and your specific cooling and heating needs.

User questions & answers

Question: how do i order the 25' lineset
Answer: Hi, Amazon also sells longer line sets. The system comes with 16 feet lines but if you are looking for longer lines any lines that are 1/4" x 3/8" would work for the 9000 BTU system.
Question: what is the HSPF for the 9000btu unit
Answer: Thank you for your question. Covac's Series-4 9000 BTU has a HSPF4 of 10.
Question: Can you cool multiple rooms
Answer: We use this particular mini-split to cool an area about 16 x 24. It would probably handle two adjacent rooms, up to 400 square feet. It works great.
Question: Would I need vaccum pump
Answer: Yes, it is recommended to vacuum the lines after installation. After checking for leaks, you can release the refrigerant inside the pre-charged condenser.

User questions & answers

Question: How many runs or ducts can you have off of this unit? The pictures show 3 rooms, I need to run
Answer: You make your own supply plenum box using fiberglass duct board and attach duct collars based on CFM air flow for each room and run the round ducts accordingly. Simply consider you have 400 CFM air flow per 12000 BTU capacity available and distribute that as needed for each of the spaces. Approximately 0.8 to 1 CFM per square foot. The diameter of the ducts you use will determine the amount of the air flow it can transport.
Question: it shows in the photo's that unit is installed in an attic , can this unit be used outside , rather than inside. seems like less heat build up
Answer: Indoor unit is an indoor unit. It must be installed inside. It can be installed in the attic, or inside a soffit or in a crawlspace, or in the ceiling cavity.This is a concealed ducted system just like your central AC.
Question: does this unit come charged with freon
Answer: All oour systems bring sufficient refrigerant for up to 25' line set lengths. The refrigerant is factory charged into the outdoor unit. After installation and evacuation of the line set, it is released by opening 2 service valves. See the installation manuals at www highseer com (DOCUMENT LIBRARY).
Question: What size (diameter) of the ducts can i use to get better performance out of this unit. Lets say i have 5 rooms, square footage is about a
Answer: You will need a minimum 24000 BTU unit. That will give you 800 CFM. A 6" duct delivers 125 CFM, 8" duct delivers 240 CFM. Distribute tot total based on square footage of each zone. You can also use dampers to restrict the flow for a zone.
