Commercial Chiller Installation in Downey (Air‑Cooled & Water‑Cooled)

Why Downey businesses choose #1 AC Guys

#1 AC Guys is a family business in its fourth generation with more than 80 years of engineering know‑how. We specialize in complex commercial HVAC, delivering purpose‑built chiller plants that improve reliability, energy efficiency, and indoor air quality. Our mission is healthier air for healthier lives—supporting the comfort, productivity, and well‑being of everyone in your building.

Air‑Cooled vs. Water‑Cooled Chiller Installation

Air‑Cooled Chillers: Ideal for tight timelines and sites without a cooling tower. They offer lower first cost, simplified maintenance, and fast installations on the roof or at grade. Great for mid‑size office buildings, retail, schools, and light industrial facilities in Downey.

Water‑Cooled Chillers: The workhorse for larger loads and central plants. Paired with a cooling tower, pumps, and variable frequency drives, water‑cooled systems deliver excellent part‑load efficiency and quieter operation—perfect for hospitals, manufacturing, labs, hotels, and mixed‑use campuses.

Our engineers evaluate load profiles, redundancy (N+1), acoustics, spatial constraints, lifecycle cost, and utility incentives to recommend the right technology for your building and budget.

End‑to‑End, Turnkey Delivery

We handle everything: detailed load calculations, equipment selection, Title 24 compliance, seismic restraints, rigging and crane plans, piping and pumping, cooling towers, glycol loops if needed, water treatment coordination, insulation, controls integration (BAS/BMS), start‑up, test and balance, and commissioning. You get a single accountable partner from concept to sign‑off.

Design‑Build Expertise for Complex Projects

Whether you’re upgrading an aging chiller in Downey, converting to a central plant, or phasing a live‑facility retrofit, our design‑build team minimizes downtime and risk. We tailor staging and tie‑ins around your operations, provide temporary cooling where required, and document a clear safety and communication plan for every milestone.

Controls, IAQ, and Energy Optimization

Smart controls make chillers far more efficient. We integrate setpoint reset, condenser water optimization, chilled water delta‑T improvement, pump VFDs, and demand‑based sequencing. We also support enhanced filtration and ventilation strategies that help improve indoor air quality—aligning with our core mission of healthier air in every space.

Factory‑Trained, Brand‑Agnostic

Our engineers have trained with leading global manufacturers, including Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea, Gree, and Haier (China). This foundation, combined with extensive field experience, helps us select and integrate the right air‑cooled or water‑cooled chiller, pumps, towers, and controls for your application—without brand bias, and always to your performance goals.
