TLDR

• Daikin Applied expanded its Phoenix facility from 58,000 to 191,000 square feet, boosting production capacity for modular hydronic and electric HVAC systems by about 150%.
• These factory-built, pre-tested systems reduce onsite installation time and improve quality, making them ideal for commercial, industrial, and data-center cooling projects.
• The modular design allows staged capacity upgrades, helping contractors, property managers, and owners manage tight schedules and growing cooling demands more efficiently.

Daikin Applied has tripled its modular HVAC manufacturing space with a new 191,000-square-foot facility in Phoenix, opening on October 14, 2026. This expansion more than triples the previous 58,000-square-foot footprint and boosts production capacity by about 150% for custom hydronic (water-based) and electric modular systems. These factory-built, pre-tested units are designed to cut onsite installation time and improve quality. The growth supports rising demand for scalable cooling solutions in commercial buildings and data centers, helping contractors, property managers, and facility owners manage projects faster and with less disruption.

Compliance and approvals to line up early

Modular HVAC units often come with UL or ETL safety listings, which show they meet strict safety standards. They also usually carry AHRI performance ratings, meaning their energy efficiency and output have been tested. Be sure to confirm exactly which certifications come with each system you order. Since these systems are built offsite, inspections can be faster and simpler. However, local rules vary, so check with your authority having jurisdiction (AHJ) to know what approvals you’ll need. Don’t wait until installation to verify energy codes, seismic requirements, wind loads, and noise limits. Planning these details early helps avoid delays and costly changes. Proper documentation will be needed to prove compliance, so gather all paperwork upfront. Staying ahead with permits and paperwork keeps your project on track and ensures your modular system meets all safety and performance rules.

What this means for contractors and facility teams

For contractors, the larger modular manufacturing footprint means less onsite assembly. This helps manage tight labor by making installation schedules more predictable. Property and facility managers can benefit from phased upgrades that keep buildings occupied during work. Modular systems allow shorter cutovers, which means less downtime and disruption. Owners and buyers will find more capacity for custom HVAC gear, reducing lead times and cutting project delays. This boost in production supports growing demand, especially for mission-critical cooling in commercial and data-center settings. Overall, the expansion offers practical advantages that simplify planning and execution for everyone involved.

How modular hydronic and electric systems scale

Modular HVAC systems are designed to grow in stages as your cooling needs increase. This is especially useful for data centers, where computing equipment generates more heat per rack over time. You can add more modules step-by-step, matching capacity with demand without a full system overhaul. Each module is factory tested before shipment. Factory testing means the system is checked for performance and quality in a controlled setting, which lowers the risks during commissioning. Commissioning is the process of starting up the system and verifying it works as intended on site. Modular systems also come with clear connection points for power, water, and controls. These tie‑ins make it easier to link new modules with existing HVAC plants and building automation systems (BAS), which manage heating and cooling automatically. This streamlined integration helps keep everything running smoothly as you expand your system.

Steps to capture the modular advantage now

Contractors should start by pre-qualifying sites for crane access, rigging paths, and utility connections. This helps lock in installation schedules and avoids delays. Property managers need to plan phased capacity upgrades carefully. Mapping out downtime windows and coordinating with tenants well in advance ensures spaces stay operational during work. Building owners and facility managers should engage vendors early. Ask about lead-time options and consider factory witness testing, which means observing system tests before shipment. This process helps catch issues early and smooths commissioning. Taking these steps can maximize the benefits of modular HVAC systems, making projects more predictable and efficient from start to finish.

Frequently Asked Questions

What is the significance of Daikin Applied's new Phoenix modular HVAC facility?

Daikin Applied expanded its Phoenix facility from 58,000 to 191,000 square feet, tripling its modular HVAC manufacturing space. This growth boosts production capacity by about 150%, helping meet rising demand for custom hydronic and electric systems, especially for commercial and data-center projects.

How do modular HVAC systems benefit contractors and property managers?

Modular HVAC systems arrive factory-built and pre-tested, reducing onsite assembly and installation time. This leads to more predictable schedules for contractors and allows property managers to phase capacity upgrades with less disruption to occupied buildings.

What does it mean that these HVAC modules are factory-tested?

Factory testing means each HVAC module is fully assembled and checked before shipping. This reduces risks during commissioning, which is the startup and performance verification phase, ensuring better quality and fewer delays on site.

How can modular HVAC systems adapt to changing cooling needs, like in data centers?

Modular systems are designed to scale in stages as cooling demands grow. For data centers, this means adding more modules as computing density increases, allowing capacity upgrades without major redesigns or extended downtime.
