Ductless air conditioning systems have been gaining popularity for their energy efficiency and affordability. In this article, we will review the best mini split AC units and help you choose the perfect model for your home.

Choosing the Best Mini Split for You

If you're considering a ductless mini split AC, it's important to understand the key factors to consider.

Seasonal Energy Efficiency Ratio (SEER)

SEER measures how efficiently your device uses energy to cool your home. Higher SEER ratings indicate greater energy efficiency.

Heating Seasonal Performance Factor (HSPF)

HSPF measures how efficiently your device heats your space. Similar to SEER ratings, higher HSPF numbers indicate better efficiency.


You should also consider the square footage of the area you want to treat. Here is a chart showing the ideal square footage ranges for the mini splits mentioned in our best-of list.

Capacity (BTU/hour) Square footage
9,000-12,000 350-550
18,000-24,000 750-1,500

Single-Zone and Multi-Zone Systems

Ductless mini split ACs come in single-zone or multi-zone configurations.

Single-Zone Ductless Mini Split

This system consists of one condenser (outdoor unit) and one air handler (indoor unit). It is ideal for homeowners who want to cool or heat a specific space, such as an add-on or converted garage.

Multi-Zone Ductless Mini Split

A multi-zone system has one condenser that controls multiple air handlers. These systems can connect with up to eight air handlers. If you have a larger space or want to cool multiple rooms, a multi-zone system is the way to go.

Mini Split Cost

The cost of a ductless AC mini split installation can range from $2,000 to $14,500, depending on various factors such as the number of indoor units and the type of system. Some companies offer bundled packages, while others allow you to mix and match condensers and air handlers for a customized solution. Wall-mounted air handlers are usually the most affordable option.

Why Choose a Ductless Mini Split AC?

A ductless mini split system cools and heats your home without the need for HVAC ductwork. It consists of an outdoor unit, an indoor air handler, and refrigerant lines that connect the two.

Here are some reasons why ductless mini split ACs are becoming increasingly popular:

  • Ductless ACs save more energy compared to ducted systems, with potential energy savings of up to 30%.
  • With regular maintenance, a ductless system can last 20 years or more.
  • Ductless mini splits are quieter than ducted systems and window ACs, thanks to the near-silent operation of indoor air handlers.
  • Many ductless systems also function as dehumidifiers, helping to remove excess moisture from your space.

Is a Ductless Mini Split Worth It?

Regardless of where you live, a ductless mini split can be a fantastic investment for your home. They offer greater efficiency, customization, and quieter operation compared to traditional ducted systems.

In recent years, the American mini split market has seen significant growth, with a wide range of high-quality products available. There has never been a better time to consider a ductless mini split AC for your home.

FAQs on Ductless Air Conditioners

Q: How does a ductless AC work? A: A ductless AC works similarly to a central air conditioner or heat pump in cooling mode, but without the need for ductwork. Conditioned air is distributed through indoor air handling units installed on ceilings or walls.

Q: How expensive are ductless air conditioners? A: The cost of ductless air conditioners can range from as low as $2,000 for a smaller unit with a single indoor air handler to as high as $14,500 for a large, highly efficient system with multiple indoor air handling units. The national average cost is around $3,000.

Q: How many square feet does a ductless mini split cover? A: A 12,000 BTU ductless mini split can cover approximately 550 square feet. If you need to cool a larger area or your entire home, you can opt for a system with a higher capacity.

Remember, when choosing a ductless mini split AC, consider factors like SEER and HSPF ratings, capacity, and the type of system that suits your specific needs. With the right unit, you can enjoy efficient and customizable cooling and heating for many years to come.
