Glendale Commercial Hospital & Lab Ventilation — Lennox Systems

Healthcare and laboratory environments demand ventilation that is reliable, verifiable, and energy aware. In Glendale, #1 AC Guys provides design‑build and retrofit solutions that help your teams deliver excellent care and high‑quality research, while managing lifecycle costs and uptime risk. We work seamlessly with general contractors, facility managers, and compliance consultants to move projects from concept to commissioning.

Hospital & lab ventilation services

• Isolation rooms (AIIR/negative pressure) and protective environment rooms (positive pressure).
• Operating rooms and procedure suites with temperature/humidity and ACH targets.
• Sterile processing and clean support areas—pressure cascades and exhaust management.
• Laboratories and research spaces, including BSL‑2/BSL‑3‑capable designs with your certifier.
• Compounding pharmacies—ventilation solutions aligned with USP 797/800 parameters.
• Lennox commercial AHU/RTU replacements, retrofits, and redundancy planning.
• DOAS/ERV for outside air loads, heat recovery, and code‑driven ventilation rates.
• Filtration upgrades (MERV‑13+ to HEPA), UV‑C options, and corrosion‑resistant coils.

Our team understands the realities of hospital campuses and active lab buildings in Glendale—limited shutdown windows, infection prevention protocols, and tight construction schedules. We plan phasing carefully, maintain clean work practices, and coordinate closely with your infection control and EHS teams.

Lennox in healthcare and lab applications

We service and retrofit Lennox commercial rooftop units and air handlers to deliver the outside air volumes, dehumidification, and control accuracy healthcare and labs require. From high‑capacity economizers and energy recovery to upgraded filter racks and variable‑speed fan arrays, we configure Lennox equipment to meet target ACH, pressure, and temperature/humidity envelopes—while improving resilience and serviceability.

• High outside‑air operation with proper conditioning and reheat strategies.
• Enhanced filtration pathways for MERV‑13+ and HEPA housings where applicable.
• Fan arrays and VFDs for stable pressurization and redundancy.
• BACnet integration for alarms, trends, and proof‑of‑performance reports.

An engineering‑first process

• Assessment & Planning: Field survey, airflow baselining, risk and compliance gap review.
• Design: Load calculations, ventilation modeling, pressure zoning, equipment selection, and drawings.
• Build & Integrate: Clean installation practices, controls programming, and BMS tie‑in.
• Commissioning & Verification: Functional testing, trending, and balancing coordination.
• Training & Support: O&M guidance, PM schedules, and rapid‑response service.

Beyond Lennox, our specialists are factory‑trained by Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). This multi‑platform expertise helps us integrate VRF/mini‑split zones for staff areas, imaging suites, or offices alongside your central plant—without compromising pressure regimes or code‑driven ventilation.

Standards, documentation, and permits

We align designs with ASHRAE 170 ventilation guidelines, CDC recommendations, and California Title 24 energy code. Our team prepares clear submittals and permit‑ready drawings and coordinates with the City of Glendale and HCAI (formerly OSHPD) as needed. We provide owner training and documentation to support audits, accreditation, and ongoing compliance checks.
