Mini Splits are growing in popularity as the most efficient and effective device for cooling homes. Thanks to their design, you can use these units to carry out zonal cooling of your home. The units have multiple evaporators that are connected to a single outdoor air unit or compressor.
You can control every evaporator independently of the others and achieve effective control of temperature in the rooms you use. However, choosing the right mini split for your home is not an easy task.
You need to be sure about the size of the home to get the right device. In this guide, we will take you through the process of selecting the right mini split for your home. We will also review the best mini splits for 1500 square feet spaces.
How Many BTU to Cool 1500 sq ft
You need about 24,000 BTUs to effectively cool and warm the air in a 1500 square feet space. The actual number of BTUs that you need to condition the air in such a space varies with other factors.
If your house’s ceiling is higher than the standard 8 feet, you will have to adjust the total number of BTUs upwards. Also, if your house is poorly insulated, increase the number of BTUs by a small percentage.
Homes that are in areas where the climate is exceptionally high need extra BTUs for cooling. If your home is in such an area, it may be wise to go for a mini split with a higher BTU value. Such a mini split will adequately heat and cool the air in your house.
How Many Watts does a 24000 BTU Mini Split Use?
A 24000 BTU mini split will draw about 2400 watts of power when running under ideal conditions. The actual number of watts that such a mini split draw varies from 2300 to 2800.
New units tend to be more energy-efficient than older ones. Also, large mini splits with a BTU rating of 24,000 and above are less energy-efficient than smaller ones with lower BTU ratings.
Also, mini splits that have high EER values are more efficient than those with low EER ratios. Thus, if your 24000 BTU mini split has a high EER ratio of about 12.5, it will consume fewer watts than one with a lower EER ratio.
Most brands of mini splits function when connected to 110v to 120v circuits. Typically, homes have 110v to 120v circuits. Matching the voltage of your mini split with that of the home is important. Connecting your mini split to a circuit that has a high voltage may lead the circuit to break or cause fires.
What Size Breaker do I Need for a 24000 BTU Mini Split?
It would be best to have a 20-amp or 25-amp size breaker for your 24000 BTU mini split. This amp breaker size is powerful enough to accommodate the voltage and wattage that a 24000 BTU mini split draws when functioning.
Installing a breaker with less amperage may pose various risks. It is always safe to use the exact specifications that the manufacturer recommends. You will always find the details on the manual that comes with your mini split.
Mini splits vs. Central Air Conditioners
It is not easy to choose between mini splits and air conditioners. While mini splits provide personalized cooling and heating of the air in small homes, they lack the power associated with central air conditioners. Standard central air conditioners are perfect for large homes and commercial buildings.
Mini splits do not use ductwork. This means that if you have a mini split, you will have conveniently overcome the need to purify the air of allergens and other impurities. Ductworks of central heating systems commonly contribute to the distribution of germs in the air. Moreover, the lack of ductwork in mini splits means that you will not waste energy through leakages and cracks that occur along central heating system’s ductwork.
Level of Control
Mini splits afford users a higher level of control than traditional central heating systems. You can use a mini split to cool or heat specific rooms at any given time. Every indoor unit operates independently of the others.
This level of control is important because it lets you create a comfortable indoor environment. However, central heating systems do not have this level of control. The systems automatically heat or cool the entire house. Thus, there is considerable wastage of heating or cooling energy when one uses a central heating system.
It is easier to install a mini split than a central air conditioner. Mini splits require a small hole to be drilled on the wall. The wall provides space for passing the refrigerant lines. Installation of a central air conditioning system takes a long time because of the complex processes involved.
One must lay the ductwork and maintain it for a long time. Maintenance of the ductwork involves continually checking them for leakages and cracks. This additional cost of maintenance is unheard of when one uses a mini split.
However, remember that whether you use a mini split or a central air conditioning system, it is a good idea to have a professional technician do it for you. Your device’s warranty will be valid if you let a professional and certified technician do the installation for you.
How to Use Mini Split Systems Efficiently
You can get the best out of your mini spits by following these simple recommendations.
- Regular cleaning. Remember to clean the air filters in the indoor units at least once per month. Some brands have an indicator system that alerts you when you need to clean the filters.
- Use the auto control features. once you have selected the ideal temperature for every room, let the air split fans automatically adjust the performance to maintain the temperature in an ideal range.
- Insulate your home correctly. It is cheaper to warm and cool a house that is insulated adequately than one which is not. Keep your rooms adequately insulated to minimize wastage of energy used to cool or warm the air.
