U.S. Split Units Market Size

U.S. Split Units Market Trends and Growth Drivers

Adoption of Inverter Technology Is Key Market Trend

• The adoption of split ACs with the inverter technology is a key trend in the U.S., as it makes split units more suitable and reliable.
• Additionally, these units have the binary on/off mechanism, and they use variable-speed compressors, which make them preferred in locations with regular power cuts.
• Furthermore, these systems are quieter than the standard split ACs, thereby increasing comfort and offering advantages in low-noise areas, such as residential colonies, schools, libraries, and hospitals.
• Power consumption decreases with the use of inverter split ACs.
• The inverter technology converts DC power to AC, which helps in increasing energy efficiency and decreasing electricity bills.
• Moreover, inverter-driven split systems come with modern microprocessors, which help take temperature readings from various parts of the room.
• This helps in providing uniform cooling across the room.

Rise in Housing Development Is Key Market Driver

• With the rise in the population, infrastructure development is picking up.
• People are moving to the country from around the world for better employment opportunities and education.
• Over 80% of the population of the country lives in cities, making the U.S. one of the most-urbanized nations in the world.
• With the growth in the number of built structures in cities, there is an increasing need for efficient cooling solutions, such as split air conditioners.
• In 2023, the federal government directly funded construction projects worth USD 44.8 billion and distributed an additional USD 81.5 billion to states.
• These units provide optimal climate control, while occupying minimal space, which makes them popular in smaller spaces, which are becoming the norm in cities.
• Furthermore, many historical buildings in the country are being renovated with modern amenities, to attract tourists.
• Split units are a good fit for these buildings as they were not designed for central air conditioning.
• Additionally, developers are focusing on green building practices, due to which there is a rise in the adoption of energy-efficient technologies, especially in commercial and residential buildings.
• The Energy Star ratings and the LEED certification are highly sought-after by both real estate developers and building owners.
• As per studies, there are over 124,000 green-certified buildings in the U.S., the most anywhere in the world.
• Split units provide a reliable solution for the same by producing a low carbon footprint, by consuming less power.

Regulatory Compliance Is Key Market Challenge

• Regulatory compliance, such as the mandates for energy efficiency, consumer safety, and environmental sustainability, act as the key market challenges.
• With the rise in global warming levels, the Government of the U.S. is mandating strict compliance for split units.
• This means that the units that do not comply will either need to be overhauled or replaced, both of which will be expensive.
• In February 2024, the Department of Energy announced new regulations, SEER2, which state that the minimum efficiency should increase by 8–10%.
• This means that roughly 70% of the current products in usage fail to meet these new guidelines.
• Moreover, there are now mandates for using cleaner and low-GWP refrigerants, such as ammonia and CO2.
• Compliant systems consist of an array of smart controls, which will require a high initial investment.
• This means that their adoption could be limited to major commercial and industrial entities.
