Commercial Hospital HVAC Sterilization in Ontario, CA

Hospital HVAC Sterilization Specialists Serving Ontario, CA

When uptime, infection control, and survey results are non‑negotiable, hospitals in Ontario, CA rely on #1 AC Guys. We engineer, install, and maintain HVAC systems that help reduce airborne pathogens, control contaminants, and maintain required air changes per hour (ACH), temperature, humidity, and pressure relationships in critical care spaces.

Our mission is simple: healthier indoor air for healthier lives. As a family business in its 4th generation, we bring 80+ years of engineering discipline to every commercial healthcare project—pairing precision design with field‑proven installation and continuous support.

What We Engineer for Healthcare Facilities

• Operating rooms with laminar airflow, temperature/humidity control, and proper pressurization.
• Isolation rooms (AIIR/negative pressure) and positive pressure suites for sterile environments.
• ICUs, NICUs, procedure rooms, and imaging suites with stable ventilation and filtration.
• Pharmacy and cleanroom HVAC with high‑efficiency particulate capture and pressure zoning.
• Dedicated outdoor air systems (DOAS) and energy recovery serving large campuses.
• Central plant optimization and BMS integrations for reliability and visibility.

Core Sterilization and Air Quality Technologies

• HEPA/ULPA filtration at appropriate stages to capture fine particulates and bioaerosols.
• UV‑C germicidal irradiation in air handlers or upper‑room applications to inactivate microbes.
• Negative and positive pressure room controls with continuous differential monitoring.
• Precise ACH targets, temperature/humidity control, and dehumidification strategies.
• IAQ sensors, room pressure monitors, and remote alarms for real‑time verification.
• Cleanable, accessible coil and drain designs with scheduled coil sanitization protocols.

Our designs align with ASHRAE 170 ventilation requirements for healthcare facilities and current CDC guidance, while meeting California Title 24 and local authority requirements. We deliver the documentation, test data, and controls graphics your facilities team needs for survey readiness.

Our Process for Critical Environments

• Assessment and planning: site survey, risk review, and airflow mapping of critical zones.
• Engineering and submittals: sealed drawings, sequences of operation, and equipment selections.
• ICRA planning: infection control risk assessment coordinated with facility teams.
• Permitting and phasing: construction phasing that protects patients and staff.
• Installation with QA/QC: licensed techs follow strict clean‑build protocols.
• Commissioning and TAB: verification of ACH, pressure relationships, and controls.
• Validation and training: turnover packages, O&M manuals, and staff training.
• Planned maintenance: proactive PM, filter schedules, UV‑C lamp replacement, and calibration.

From rapid retrofits to ground‑up builds, we deliver repeatable results that stand up to audits and daily operations.
