Selection Criteria

Mini Split

In addition to the unit’s features, factors such as the climate or the layout of the space where the 24,000 BTU mini-split is going to be installed can prompt you to choose one model over the other.

We’ve used a wide range of parameters to select the best 24,000 BTU mini-splits, so let’s take a look at some of the most important ones.

  • Energy efficiency ratings - Most brands use energy efficiency ratings to highlight the power-saving features of their ductless mini-split systems. We’ve used these ratings to find the models that don’t consume vast amounts of power during the heating or cooling season.

  • Price range - Units that have 24,000 BTU output capacity are more expensive than 1.5-ton or 1-ton models. We’ve included both affordable and expensive mini-splits in this article so that you can choose the option that best fits your budget.

  • A maximum number of zones - Having the ability to divide the unit’s output into multiple zones can lower your monthly utility bills since you don’t have to regulate the temperature in all zones at the same time. Units that have just one zone are a better choice for a large space that doesn’t contain barriers that prevent the cold or hot air from spreading through the room.

Types of 24,000 BTU Mini-Splits

All ductless mini-split systems operate on the same principle. The cold or hot air is generated by using line sets to move the refrigerant between the unit’s outdoor and indoor components.

Depending on the number of indoor components in a system, you can choose between the following types of 24,000 BTU mini-splits.

  • Single-zone - The unit treats the entire coverage area as a single zone because it has just one indoor air handler. This type of mini-split isn’t an ideal solution for two-story houses since walls, and other types of barriers limit their coverage range.

  • Multi-zone - 24,000 multi-zone mini-splits usually feature two indoor air-handlers with identical power output capacities. So, in most cases, you’ll get a pair of 12,000 BTU indoor air handlers since models that split the unit’s cooling, or heating output unevenly are rare. You need to get a mini-split with a higher output capacity if you’re searching for a three-zone system.

The Coverage Area of 24,000 BTU Mini-Splits

Under ideal conditions, you’re going to need 20 BTU to heat or cool a 1sq/ft of floor space. But, the indoor and outdoor conditions are rarely perfect, which makes it difficult to estimate the coverage range of 2-ton mini-split systems.

Depending on the climate in your region, these units can heat or cool between 1000sq/ft and 1,200sq/ft of floor space which makes them a good choice for 4-room apartments.

All types of ductless mini-splits have an operating temperature range, and extremely hot or cold ambient temperatures can reduce their coverage range.

The position of the indoor air handlers also affects the unit’s coverage range since installing them in poorly insulated spaces is going to limit their cooling and heating capacities.

Moreover, you need to check if the unit’s cooling and heating outputs are identical since some models cannot heat a 1,200sq/ft space. Read our guide to residential insulation to find out how to prevent heat transfer in your home.

The Power Efficiency of 24,000 BTU Mini-Splits

Mini Split

Estimating the costs of using a 24,000 BTU unit to regulate the temperature in your home shouldn’t be too difficult since most brands include energy efficiency ratings in descriptions of all their products.

The average cost of using a 2-ton mini-split for an hour is $0.32, but the unit’s actual power consumption depends on its SEER, EER, and HSPF ratings.

Each of these ratings is calculated at specific outdoor temperatures, and it might change if the current ambient temperature is higher or lower than the one used to measure the unit’s energy efficiency.

Energy Star certified models have the best power-saving features, but they’re more expensive than the models that don’t have this certificate. 2-ton mini-splits with SEER ratings above 18 and EER ratings above 8.5 are considered energy efficient even if they don’t have the Energy Star certification.

You should opt for a 24,000 BTU mini-split that has an HSPF rating above 9.5 if you’re planning to use this system for heating. Browse through our guide to furnaces if you need a heating system for an entire house.

The Essential Features of 24,000 BTU Mini-Splits

Heating and cooling aren’t the only functions mini-split systems offer. In fact, most units have the same set of features regardless of their size, and you can use them to regulate air humidity levels or filter out allergenic particles.

Here are some of the most important features a 24,000 BTU mini-split should have.

  • Auto clean function - Units equipped with this feature eliminate the moisture from the indoor air handler automatically. This prevents different types of microorganisms from damaging the system’s components.

  • Dehumidification - Mini-splits absorb the moisture from the air while operating in this mode. Some models can absorb more than 100 pints of moisture in one day.

  • WiFi compatibility - Getting a WiFi-enabled mini-split will allow you to adjust its settings from your phone. Keep in mind that WiFi adapters are usually sold separately from the mini-split.

  • Timer - This function lets you program when and for how long the unit is going to be running.

The Most Important Factors to Consider While Choosing a 24,000 BTU Mini-Split

Mini Split

Even though you can choose from hundreds of 2-ton mini-split models, most options will offer a similar set of features. The unit’s energy efficiency rating and your budget limitation are probably the most important factors that will ultimately determine which model you’re going to choose.

We’ve listed several additional factors that might make your search for a 24,000 BTU mini-split easier, so let’s take a closer look at them.

Single-Zone vs Multi-Zone System

The number of indoor air handlers a mini-split system has isn’t going to affect its coverage range.

Multi-zone systems allow you to use air handlers independently from each other, and in doing so, they lower the amount of power the system needs to regulate the room temperature in a specific part of your home.

Single-zone models might struggle to achieve and maintain an equal room temperature across the entire coverage area if the weather is extremely hot or cold.

Heating Capacity

Mini-splits are primarily cooling systems which is the reason why some models don’t have the heating mode. The unit’s heating output isn’t always the same as its cooling output since a 24,000 BTU mini-split can supply you with 24,500 BTUs or just 12,000 BTUs of heating power, depending on the model.

These systems need more power to increase the room temperature for 1F than to lower it for 1F.

Air Filter Type

All 2-ton mini-splits have air filters that safeguard the system from insects and particles in the air that can damage its components.

Units equipped with HEPA filters capture allergenic particles like pollen or pet dander, and you should opt for a mini-split that features this type of air filter if one or more members of your family members suffer from allergies.

You should choose a model with a washable filter to avoid having to install a new filter every few months.

Noise Levels

Depending on the model, 24,000 BTU mini-splits make between 20db and 60dB of noise. Models that produce up to 30dB of noise are a great fit for bedrooms, while units with a higher noise level are better suited for shared spaces in your home or your office.

Air filters for mini-splits cost between $20 and $80, while the filter replacement service costs around $100.

Overall Cost and Warranty Length

The price of 24,000 BTU mini-splits ranges from $1,250 for entry-level models to approximately $3,000 for a high-end model. You should also add installation costs to your expenses since most 2-ton mini-splits require professional installation.

The compressor warranty is usually longer than the warranty for other parts of the system, so the model you choose might have a 7-year warranty for the compressor and a 5-year warranty on all other components.

Bear in mind that the duration of the unit’s warranty depends on the brand you choose.

The Advantages of 24,000 BTU Mini-Splits

Variety of Functions

Besides heating and cooling, 24,000 BTU mini-splits offer functions that allow you to improve your home’s ventilation system or regulate the air humidity levels. These features increase the quality of air in your home and create a healthier environment for your family.

Multiple Airflow Direction Options

2-ton mini-splits allow you to choose the direction of the airflow by changing the position of their louvers. This enables you to direct the airflow to maximize their cooling and heating capabilities or direct the air towards a specific area of the room.

Power-Saving Performances

The cost of using a 24,000 BTU mini-split for an hour is just $0.32, so your utility bill isn’t going to increase significantly even if you use the unit for several hours every day. Most models have high SEER, EER, and HSPF ratings that guarantee moderate power consumption.

The Disadvantages of 24,000 BTU Mini-Splits

Limited Coverage Range

The average size of a household in the United States is well above 2,000sq/ft, which means that 24,000 BTU mini-splits aren’t powerful enough to be the only source of heating and cooling in most homes in the United States.
