North America Dedicated Outdoor Air System Market To Reach $2,166.7 Million By 2033

North America Dedicated Outdoor Air System Market Growth & Trends

The North America dedicated outdoor air system market size is anticipated to reach USD 2,166.7 million by 2033, expanding at a CAGR of 5.5% from 2025 to 2033, according to a new report by Grand View Research, Inc. The North America Dedicated Outdoor Air System (DOAS) market is primarily driven by the growing focus on energy-efficient HVAC technologies, expanding commercial and institutional construction, and heightened awareness of indoor air quality (IAQ) and occupant well-being. The increasing adoption of green building certifications, such as LEED (Leadership in Energy and Environmental Design) and WELL, has reinforced the implementation of DOAS, as these systems ensure compliance with strict ventilation and humidity control standards while helping buildings reduce their overall energy consumption.

Market opportunities are emerging from the integration of smart controls, variable refrigerant flow (VRF) systems, and advanced heat recovery technologies, which enhance system performance and reduce operational costs. Additionally, the retrofitting of existing HVAC infrastructure in offices, healthcare facilities, and educational buildings to meet modern ASHRAE and energy code requirements presents a substantial opportunity for market expansion across the U.S. and Canada.

The market is further shaped by regulatory frameworks emphasizing sustainability and IAQ-particularly ASHRAE Standard 62.1, U.S. Department of Energy (DOE) efficiency mandates, and state-level building energy codes. These standards promote the installation of ventilation systems that provide precise control over temperature, humidity, and air quality in both new and existing structures.

Leading players, such as Carrier, Daikin Applied, Trane Technologies, Johnson Controls, and LG Electronics, are expanding their portfolios with smart-enabled, modular DOAS solutions featuring variable-speed compressors and intelligent sensors, while strengthening their regional manufacturing and distribution networks to better serve local market demand. For instance, in July 2025, Greenheck Fan Corporation expanded its DOAS product line with the RV-220 model, offering up to 29,200 CFM of airflow, 50–100 tons of packaged DX cooling, and 2,000 MBH of indirect gas heating.

North America Dedicated Outdoor Air System Market Report Highlights

• Based on capacity, the up to 20 tons capacity segment led the market in 2024 as it is commonly used in small to mid-sized commercial buildings, educational institutions, and healthcare facilities where limited space and moderate ventilation requirements favor the use of compact, energy-efficient DOAS systems.

• Based on end use, the commercial segment led the market in 2024, supported by strong demand from offices, educational institutions, healthcare centers, and hospitality facilities focused on improving indoor air quality and energy performance.

• Based on equipment type, the packaged DOAS units segment led the market in 2024, driven by their compact design, simplified installation process, and reduced maintenance needs compared to split-system configurations.

• Based on country, the U.S. market led North America in 2024, driven by expanding commercial construction, stringent indoor air quality (IAQ) regulations, and rising demand for energy-efficient HVAC solutions.

• In April 2025, Johnson Controls announced its decision to divest its global HVAC (Heating, Ventilation, and Air Conditioning) solutions business for residential and light commercial buildings, including its stake in the Johnson Controls-Hitachi joint venture, to Bosch for USD 8 billion. This transaction marks a strategic move by Johnson Controls to streamline its business portfolio.
