U.S. HVAC Rooftop Units Market Growth & Trends

The U.S. HVAC rooftop units market size is expected to reach USD 13,870.1 million by 2033, registering a CAGR of 4.9% from 2026 to 2033, according to a new report by Grand View Research, Inc. Rising construction spending in the U.S. coupled with the maintenance & replacement operations related to HVAC rooftop units is anticipated to fuel the demand for energy-efficient heating. The U.S. construction industry focuses on the development of sustainable and energy-efficient buildings. Leadership in Energy and Environmental Design (LEED) is a green building certification system developed by the U.S. Green Building Council (USGBC) that focuses on increasing energy consumption to lessen the environmental impact of excessive energy usage. These factors are expected to drive the demand for HVAC rooftop units in the U.S.

The U.S. HVAC rooftop unit market is witnessing a high demand from the commercial sector for various applications such as retail stores, restaurants, warehouses, and healthcare. Further, there is a high demand for integrated solutions to control different parameters, such as temperature, humidity, airflow, and more, remotely and from various devices. Several companies are developing solutions that offer integrated control of HVAC equipment throughout the building. The U.S. HVAC rooftop units (RTUs) market is expected to increase sales due to the availability of tax credits and rebate programs associated with purchasing energy-efficient systems. To improve the efficiency of HVAC rooftop units, various governments in the U.S., including federal and state levels, have implemented regulations such as the U.S. Department of Energy (DoE) energy conservation guidelines.

These regulations are designed to encourage the production of energy-efficient appliances while minimizing environmental risks and carbon emissions. The surging demand for replacement equipment is significantly propelling the market for HVAC rooftop units. As older systems reach the end of their operational life, industries and building owners look to upgrade to more efficient, modern units that offer better performance, energy savings, and compliance with current environmental regulations. This can be a key opportunity for the market, as it not only involves direct replacement of outdated equipment but also encourages the adoption of advanced technologies that offer superior control, integration, and sustainability features.

Manufacturers of U.S. HVAC rooftop units are adopting several strategies, such as acquisitions, mergers, joint ventures, new product launches, and geographical expansion, to enhance market penetration and cater to changing technological demands from various end-use applications, including residential, commercial, and industrial applications. For instance, in May 2024, Lennox International, Inc. unveiled its new series of HVAC offerings with a low global warming potential (GWP), highlighting its commitment to sustainability, adaptability, and high-quality performance. This residential collection will feature the eco-friendly R-454B refrigerant in Lennox-brand heat pumps and air conditioners. For the commercial sector, the entire range of rooftop units and ducted splits, including the prestigious Model L and Enlight series, will come equipped with R-454 B refrigerant.
