U.S. HVAC Unitary Heaters Market Size & Share Analysis - Trends, Drivers, Competitive Landscape, and Forecasts (2025 - 2032)

U.S. HVAC Unitary Heaters Market Growth Factors

Integration of Artificial Intelligence and Machine Learning Is Key Trend

HVAC system manufacturers are increasingly integrating AI and ML tools into unitary heaters. This helps in improving the performance of the systems, allowing them to run more efficiently. They also help control energy use, save money, and improve system efficiency. With AI and ML, HVAC systems can become more autonomous, adjusting their settings with the help of real-time data. Additionally, IoT connectivity allows people to control them from wherever they are, via a mobile app.

Growing Focus on Sustainability and Eco-Friendly Heating Options Is Growth Drivers

As environmental concerns continue to grow, more consumers are choosing eco-friendly heating options. Low-emission systems and those powered by renewable energy sources are gaining traction. This is why electric unitary heaters are becoming popular as a cost-saving option over those that burn natural gas (propane), wood, coal, and crude oil. Additionally, electrical appliances are being designed for higher energy efficiency, often with smart features. Hence, while these systems might be expensive in the short term, the long-term electricity bill reduction and regulatory compliance they offer offset the purchase price. Therefore, people are increasingly replacing their outdated unitary heating systems with new-generation electric ones, thus driving sales revenue for the players.

Competition from Alternative Heating Solutions Is Key Challenge

Ductless heat pumps, radiant heating systems, and geothermal heat pumps compete with unitary heaters as they are more energy-efficient and cost-effective in some applications and climates. This somewhat reduces the demand for traditional unitary heaters, thus hampering the growth of the market to some extent. Similarly, traditional furnaces are quite popular in the country as they efficiently heat large spaces and are compatible with centralized HVAC systems. Moreover, heat pumps are energy-efficient because they merely transfer heat, rather than creating it with a coil.

U.S. HVAC Unitary Heaters Market Segmentation Analysis

Operation Insights

The gas-fired category held the largest market share, of 55%, in 2024. This is because gas-fired unitary heaters are widely used in both residential and commercial applications due to their reliability and cost-effectiveness. These systems have higher heating efficiency and lower operational costs compared to other heating methods.

The electric category will grow at the highest CAGR, of 4.7%, during the forecast period. This is because consumers are becoming more aware of the environmental damage caused by fossil fuels. Thus, electric systems, especially those powered by renewable energy sources, are seen as more eco-friendly. Electric units are also easier and cheaper to install compared to others. In October 2023, Modine launched the Amp Dawg, an electric unit heater designed to deliver efficient and quiet heating for smaller spaces.

The operations analyzed in this report are:

• Gas-Fired (Largest Category)
• Electric (Fastest-Growing Category)
• Hydronic
• Oil-Fired

Type Insight

The horizontal category held the largest market share, of around 50%, in 2024. Horizontal units are used in the residential and commercial sectors due to their versatile and easy-to-install features. They are best for areas where floor space is limited, because they are installed along walls or ceilings.

The suspended category will grow at the highest CAGR, during the forecast period. This is because suspended units are installed on ceilings, which saves floor space, making them ideal for the commercial and industrial sectors. Further, these units now include advanced technology that improves energy efficiency, making them a popular choice for businesses looking to lower their operational spending.

The types analyzed in this report are:

• Horizontal (Largest Category)
• Vertical
• Suspended (Fastest-Growing Category)

End Use

The residential category held the largest market share, in 2024. This is because houses in most parts of the country need efficient heating systems because of the cool summers and long, harsh winters. The category’s dominance is also attributed to the increasing energy efficiency awareness and the adoption of smart technologies.

The industrial category will grow at the highest CAGR, of 4.8%, during the forecast period. This is because of the rising need for space-saving, energy-efficient heating systems in large industrial spaces, especially suspended and horizontal units. As industrial operations expand and evolve with the rise of e-commerce, Industry 4.0, and warehousing, the demand for cost-effective and reliable heating solutions is surging.

The end use analyzed in this report are:

• Residential (Largest Category)
• Commercial
• Industrial (Fastest-Growing Category)

U.S. HVAC Unitary Heaters Market Regional Outlook

• The northeast region held the largest market share, of 40%, in 2024 because the northeast region experiences cold winters with temperatures regularly below freezing. Many aging buildings in this region require replacements or upgrades, which increases the demand for more-efficient heating systems to reduce energy consumption.
• Gas-fired unitary heaters are highly common in the Northeast due to the widespread availability of natural gas.
• The Midwest region will grow at the highest CAGR, during the forecast period. This is because the Midwest is undergoing significant economic growth, especially in manufacturing and warehousing, which propels the demand for efficient heating systems for large facilities. With more construction projects, both in the residential and commercial sectors, the need for new unitary heaters is escalating in the region.

The regions analyzed in this report are:

• Northeast (Largest Category)
• Midwest (Fastest-Growing Category)
• West
• South

U.S. HVAC Unitary Heaters Market Competitive Landscape

The U.S. HVAC unitary heaters market is fragmented as it is composed of numerous players. They offer a wide variety of unitary heaters, catering to both residential and commercial sectors. Further, companies specialize in specific fuel types and technologies, and the lack of comprehensive portfolios holds any one company from clear dominance. With the increasing focus on energy efficiency and sustainability, a large number of startups are entering the market as well.
