Engineered for Complex Pasadena Roofs

Every commercial roof is unique. We perform detailed load calculations, evaluate ductwork and curb conditions, select the right Midea packaged RTU, and design seismic anchorage and vibration isolation appropriate for local codes. Our engineers plan crane logistics, roof protection, and safe rigging, coordinate with property managers, and streamline Pasadena permitting to minimize downtime.

• Right-sized capacity using industry-standard load calculations
• Curb adapters or new curbs for clean, weather-tight fit
• Seismic bracing and anchorage aligned with California requirements
• Electrical, gas, and condensate routed neatly and safely
• Controls integration for thermostats and BMS where applicable

Why Choose Midea Rooftop Units

Midea commercial packaged RTUs are designed for dependable performance, strong efficiency, and straightforward service. Paired with our commissioning process, your system delivers comfort with lower lifecycle costs.

Our factory training includes Midea (China), Fujitsu (Japan), Mitsubishi Electric (Thailand), Gree (China), and Haier (China). This depth of manufacturer training helps us handle complex retrofits, mixed-brand sites, and multi-unit strategies with confidence.

Our RTU Installation Process

• Site assessment and load calculation to right-size equipment
• Equipment selection with a clear, itemized proposal
• Permits, Title 24 documentation, and crane day coordination
• Rooftop preparation, curb adapter fit-up, and weatherproofing
• Gas, electrical, and controls connections performed to code
• Startup, airflow balancing, and manufacturer-level commissioning
• Owner training, maintenance plan options, and documentation

We verify static pressure, temperature split, and control sequences so your system starts strong on day one. Proper commissioning protects warranties and maximizes efficiency.

Healthier Air Is Our Mission

Clean air supports productivity and well-being. We design for balanced ventilation, appropriate filtration, and correct economizer settings. If needed, we can evaluate duct sealing, outside air pathways, and CO2-based ventilation strategies to meet comfort and indoor air quality goals.

Safety, Compliance, and Care

From traffic control and crane lifts to rooftop protection and fall prevention, we prioritize a safe, orderly jobsite. Our installs follow applicable codes and best practices, with thorough leak checks, electrical verification, and weatherproofing. We finish with a clean roof, labeled equipment, and a walk-through so you know how to operate your new Midea RTU.

Proactive Maintenance for RTUs

• Seasonal inspections, filter and belt service, and coil cleaning
• Economizer and controls checks for efficiency and comfort
• Refrigerant charge verification and electrical testing
• Documented reports to anticipate issues before they impact uptime

A maintenance plan stabilizes comfort, lowers operating costs, and extends equipment life—especially vital for busy Pasadena retail, office, and hospitality environments.
