Commercial, Hospital & Lab Ventilation in Los Angeles — Midea Solutions

Our core mission—healthy air for a healthy life—drives every commercial healthcare and laboratory project we touch. As #1 AC Guys, a fourth-generation family of engineers with 80+ years in engineering, we specialize in large, complex ventilation systems that must perform flawlessly. We pair Midea dedicated outdoor air and energy recovery technologies with precise room pressure control, high-efficiency filtration, and intelligent controls to achieve clean, stable, and efficient airflow in critical spaces across Los Angeles and surrounding counties.

Engineered ventilation for hospitals and labs

From emergency departments and operating rooms to BSL labs and ISO-classified cleanrooms, our team designs to the intent of leading healthcare and lab standards to help you meet compliance and operational goals. We focus on air change rates, pressure relationships, temperature and humidity stability, and filtration that matches your risk profile and process needs.

• Isolation/AIIR rooms with stable negative pressure and monitored anterooms
• Operating rooms with positive pressure, low-turbulence airflow, and tight control
• Pharmacy cleanrooms (USP 797/800) with segregated ante and buffer spaces
• Cleanrooms (ISO 14644) with HEPA/ULPA filtration and documented airflow performance
• BSL labs, vivariums, and fume hood make-up air with safe exhaust strategies
• Instrument reprocessing, decontamination, and sterile storage pressurization

Midea technologies we implement

Midea solutions allow decoupled ventilation for outstanding control and efficiency. We integrate:

• DOAS units sized for required ACH with hot-gas reheat and dehumidification
• Energy Recovery Ventilators (ERV) to capture energy while maintaining cleanliness
• Make-up air and rooftop units for reliable, maintainable outdoor air delivery
• Air handlers with high-static fans, HEPA/ULPA filter banks, and UV-C options
• Integration with Midea VRF where appropriate for sensible/latent load decoupling
• BACnet/Modbus controls for BMS integration and room-pressure monitoring

Our engineers have trained at the factories of Fujitsu (Japan), Mitsubishi Elektrik (Thailand), Midea (China), Gree (China), and Hier (China), giving us deep product insight for robust, maintainable installations.

Compliance-minded design that works in the real world

We align designs with the intent of ASHRAE 170 for healthcare ventilation, California Title 24 energy requirements, HCAI (formerly OSHPD) expectations, CDC guidance, NFPA 99, and applicable cleanroom and pharmacy standards. We produce clear calculations and submittals to streamline approvals and deliver field results that match the design.
Airflow is verified via commissioning and TAB, with pressure relationships and ACH documented for your compliance records.

• Engineered load and ventilation calculations with room-by-room criteria
• Seismic bracing and vibration control appropriate for California facilities
• Room pressure monitors with local display and BMS alarms
• MERV 13+ prefiltration with HEPA/ULPA terminal filters where required
• Sound and energy optimization to reduce operating cost without sacrificing safety

Clean, safe installation around active operations

Hospitals and labs cannot stop. We plan work in phases, coordinate after-hours when needed, and follow infection control risk assessment (ICRA) protocols to protect your staff, patients, and research. Our crews maintain clean containment, negative work zones, and meticulous documentation from demo to closeout.

Proven process from assessment to handoff

• On-site assessment and goals definition, including risk, process, and uptime needs
• Basis of design with ACH, pressure maps, filtration and controls strategy
• Detailed submittals and permitting support to accelerate approvals
• Installation by healthcare-experienced technicians with rigorous QA/QC
• Functional performance testing, commissioning, and TAB with clear reports
• Training for facilities teams and maintenance plans to sustain performance

Lifecycle value and measurable IAQ

Beyond first cost, we target lifetime reliability and verifiable indoor air quality. We deploy sensors for pressure, temperature, humidity, CO2, and particles to trend performance and alert your team before issues affect operations. Energy recovery, proper heat recovery bypass, and high-turndown fan control reduce energy while maintaining strict ventilation and pressurization.

Service area

We proudly serve Los Angeles County and nearby Orange County, Ventura County, and Western Riverside County. Whether it’s a single isolation room retrofit or a multi-building modernization, our engineers bring the same precision and accountability to every project.
