Downey laboratories choose #1 AC Guys for dependable environmental control that protects research quality, productivity, and compliance. We unite 80+ years of engineering experience with AC PRO commercial solutions to deliver accurate temperature, tightly managed humidity, stable room pressurization, and cleanroom‑grade filtration. Our fourth‑generation team designs for your exact process loads, integrates with your BMS, and implements redundancy for continuous operation. We specialize in complex commercial projects—cleanrooms, biotech suites, aerospace test labs, pharmacies, and university research spaces. Trained at manufacturer facilities in Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China), we build systems that are efficient, serviceable, and future‑ready. Count on rapid deployment, meticulous commissioning, and proactive maintenance across Los Angeles County and surrounding areas.
Your laboratory environment is a controlled ecosystem. We design and implement integrated systems that align airflow, temperature, humidity, pressure, and filtration to your specific protocol. Whether you operate an ISO 14644 cleanroom, a USP 797/800 compounding pharmacy, a BSL prep room, or an aerospace QA lab, our approach ensures data integrity, operator safety, and compliance readiness.
We specify and integrate AC PRO commercial‑grade components, controls, and accessories to create robust, maintainable systems. Paired with our engineering, AC PRO solutions enable fast serviceability, parts availability, and long‑term reliability—critical in mission‑critical lab environments.
Our engineers are trained at manufacturer facilities in Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China), giving us deep platform knowledge for high‑efficiency equipment and advanced controls that meet demanding lab sequences.
We thrive on complexity. From greenfield facilities to phased retrofits in occupied spaces, we model load profiles, air change rates, pressure cascades, and filtration strategies to deliver a complete, code‑aligned solution.
We align with ASHRAE guidance, ISO 14644 principles, USP 797/800 requirements for sterile compounding, and applicable OSHA/CDC recommendations. Our designs also consider local codes, AQMD guidance, and California Title 24 energy standards to balance compliance with lifecycle cost.
The result: stable conditions, audit‑ready documentation, and predictable operating budgets.
A healthy lab starts with healthy air. Our family business is in its fourth generation, and we bring 80+ years of engineering knowledge to every project. From Downey to greater Los Angeles County—and into Orange County, Ventura County, and Western Riverside County—we provide responsive service and long‑term partnership.
Expect transparent scopes, clear timelines, and measurable outcomes: tighter control bands, fewer alarms, and higher uptime.
If your Downey laboratory requires precise environmental controls—temperature, humidity, pressure, and filtration—partner with a team that builds for accuracy and uptime. We’ll assess your facility, define performance targets, and deliver a clear plan from design through commissioning and maintenance.
