When it comes to DIY mini split ACs, one size does not fit all.

It is crucial to correctly size the unit according to the specific needs of your space. A unit that is too small will struggle to cool or heat your room effectively, while a unit that is too large may result in wasted energy and higher utility bills.

Here are a few factors to consider when sizing a ductless AC:

– Room Size: The size of your room plays a crucial role in determining the BTU (British Thermal Units) capacity required for your DIY mini split AC. A general rule of thumb is to estimate around 20 BTUs per square foot.

However, factors such as ceiling height, insulation, and sun exposure should also be taken into account. – Climate: The climate in your area will also impact the sizing of your ductless AC.

For hotter climates, a higher BTU capacity may be necessary to effectively cool your space. Similarly, colder climates may require a higher BTU capacity to adequately heat your room.

– Occupancy: The number of occupants in a room can affect the cooling or heating load. More occupants will generate additional heat, thus requiring a higher BTU capacity for your DIY mini split AC.

By correctly sizing your DIY mini split AC, you can ensure optimal comfort and energy efficiency in your home. Best DIY Mini Split ACs – Full Reviews:

Pros and Cons of DIY Ductless AC Systems

DIY ductless AC systems have gained popularity in recent years as a cost-effective and convenient solution for achieving personalized comfort in homes. These systems offer many benefits, such as lower energy consumption and ease of installation.

However, there are also drawbacks that should be considered before opting for a DIY ductless AC system. In this section, we will delve into the pros and cons of these systems to help you make an informed decision.

Pros of DIY Ductless AC Systems:

1. Cost Savings: One of the primary advantages of DIY ductless AC systems is the potential for cost savings.

These systems typically have a lower upfront cost compared to traditional central air conditioning systems. Additionally, ductless ACs operate on precise temperature control, allowing you to cool or heat specific zones of your house instead of wasting energy cooling or heating the entire space.

2. Energy Efficiency: DIY ductless AC systems are known for their energy efficiency.

By delivering cooled or heated air directly to the desired areas, these systems eliminate the energy losses associated with ductwork. Furthermore, many models come with built-in features like programmable timers and energy-saving modes, allowing you to further optimize energy consumption and reduce your utility bills.

3. Easy Installation: As the name suggests, DIY ductless AC systems are designed to be installed by homeowners.

Compared to traditional AC systems, which require professional installation and ductwork, ductless systems are much simpler to set up. They consist of an outdoor unit connected to one or more indoor units via refrigerant lines.

The ease of installation saves time and money, as you won’t have to hire an HVAC technician. 4.

Zoning Options: Another advantage of DIY ductless AC systems is the ability to create customized zones within your home. This means that different rooms or areas can be set to different temperatures, allowing for individual comfort preferences.

Zoning options are particularly beneficial if certain areas of your house are seldom used or if there are members of the family who prefer different temperature settings. 5.

Improved Indoor Air Quality: Traditional ducted HVAC systems often accumulate dust, allergens, and other contaminants within the ductwork. DIY ductless AC units bypass this issue as they do not rely on ducts to distribute air.

Instead, they utilize individual air handlers that filter and circulate air directly in the rooms, leading to improved indoor air quality. Cons of DIY Ductless AC Systems:


Upfront Cost: While DIY ductless AC systems can be cost-effective in the long run, they may require a significant upfront investment. The initial cost of purchasing and installing the units can be higher compared to traditional window or portable AC units.

However, it is important to consider the long-term energy savings and increased efficiency, which can offset the initial expense. 2.

DIY Installation Challenges: While the installation of a DIY ductless AC system can be straightforward, it is not without its challenges. Homeowners may encounter difficulties mounting the indoor air handlers or properly sealing the refrigerant lines.

Improper installation can negatively impact the performance and efficiency of the system. It is crucial to carefully read and follow the manufacturer’s instructions or seek assistance from a professional if needed.

3. Limited Brand and Model Options: While DIY ductless AC systems do offer a variety of brand and model options, the selection is still more limited compared to traditional central air conditioning systems.

This can limit your ability to find the exact specifications or features you desire. However, as the popularity of DIY ductless ACs continues to grow, more brands and models are entering the market, providing consumers with additional choices.

4. Aesthetics: While DIY ductless AC units offer flexibility in terms of installation location, they can present challenges when it comes to aesthetics.

Indoor air handlers are typically mounted on walls or ceilings, which some homeowners may find visually unappealing. However, many manufacturers are now designing units with sleek and modern aesthetics to blend seamlessly with various interior styles.

5. Maintenance and Repairs: DIY ductless AC systems require regular maintenance to ensure optimal performance.

This includes cleaning or replacing filters, as well as checking for any leaks or refrigerant issues. While these maintenance tasks are relatively simple to perform, it is essential to stay on top of them to avoid potential problems.

Additionally, if repairs are needed, it may be necessary to contact a professional technician with experience working on ductless AC systems. In conclusion, DIY ductless AC systems offer several advantages, including cost savings, energy efficiency, easy installation, zoning options, and improved indoor air quality.

However, homeowners should also consider the upfront cost, potential installation challenges, limited brand options, aesthetic considerations, and the need for regular maintenance and repairs. By weighing the pros and cons, you can determine if a DIY ductless AC system is the right choice for your home, providing you with personalized comfort and energy savings.
