Why choose York RTUs for Rialto facilities

• High-efficiency options to reduce demand charges and operating costs
• Factory‑available economizers for free cooling during cooler Inland Empire mornings and evenings
• Robust construction and serviceability that shorten maintenance windows
• Broad model range to match both like‑for‑like swaps and modernization projects

Our team is factory‑trained with Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). We apply that advanced training to installation quality, airflow management, and controls—ensuring your York rooftop unit performs to spec without shortcuts.

Our engineered installation process

Every building is different. We start with right‑sizing and a clear sequence of operations that fits your business hours and safety requirements.

• Survey & Design: load calculations, duct static review, curb/roof assessment, electrical capacity, gas piping, and condensate management
• Submittals & Approvals: equipment selections, curb adapters, economizer strategies, and Title 24 acceptance testing plans
• Crane Day: rigging, traffic/parking coordination, roof protection, and old‑to‑new swap with debris haul‑away
• Controls Integration: smart thermostat or BACnet, sensor placement, DCV/CO₂ setup, and economizer configuration
• Commissioning: verify airflow (CFM/ESP), charge, superheat/subcool, safeties, and sequence validation

Expect clear communication, daily updates, and documented checklists. We finish with owner training and a maintenance plan to lock in your efficiency gains.

Compliance and documentation

We handle permitting and inspections for Rialto and the surrounding Inland Empire, including Title 24 documentation and acceptance testing. Our installations follow California energy code best practices, manufacturer specifications, and applicable safety standards to protect warranties and ensure reliable operation.

Healthy air first

Our mission is healthy air in your building for a healthy life. We evaluate filtration levels, outside air rates, and ventilation controls to support better IAQ without sacrificing energy efficiency. If needed, we can incorporate enhanced MERV filtration, UV-C, and air quality monitoring as part of your RTU strategy.

What to expect on crane day

We coordinate crane arrival, rigging, and a safe lift path. Your old unit is removed, curbs are adapted or replaced, and the new York RTU is set and secured. Electrical, gas, and controls are connected; ducts are sealed and insulated; and the roof area is cleaned before we leave. Most single‑unit replacements complete within a day; multi‑unit projects may span several days with phased scheduling to keep critical areas conditioned.

Ongoing support and lifecycle value

• Preventive maintenance tuned to manufacturer specs
• Proactive monitoring options to catch issues before they become downtime
• Filter and belt programs, coil cleaning, and economizer verification
• Performance reporting so you can verify energy savings over time

We design for the total cost of ownership—lower energy, fewer breakdowns, and longer equipment life.
