Commercial Chiller Maintenance in Downey, CA

Commercial chiller maintenance in Downey—done by engineers

When your building or facility relies on chilled water, reliability is non‑negotiable. #1 AC Guys is a fourth‑generation family business with 80+ years of engineering experience, focused on high‑stakes commercial HVAC across Downey, Los Angeles County, Orange County, Ventura County, and Western Riverside County. Our mission is healthy, stable indoor environments—delivered through disciplined maintenance that minimizes downtime, reduces energy use, and extends asset life.

What our maintenance program includes

• Seasonal inspections and functional testing: starters, VFDs, safeties, controls, sensors, and setpoints
• Refrigeration circuit care: leak checks, superheat/subcooling assessment, oil condition review
• Mechanical integrity: bearings, belts, alignment, vibration/noise diagnostics
• Condenser/evaporator performance: approach temperature checks, tube/coil cleaning schedules
• Water quality coordination: condenser water treatment alignment and scale/corrosion mitigation
• Controls and BAS: sequence verification, trend review, reset strategies, alarm rationalization
• Energy optimization: kW/ton benchmarking, part‑load tuning, night purge and economizer strategies
• Documentation: service reports, performance baselines, capital planning recommendations

Every visit is engineered to produce measurable results—lower kW/ton, stable leaving‑water temperatures, and fewer nuisance trips—so your building runs smoothly during peak demand.

Chiller types and plant components we service

• Air‑cooled and water‑cooled chillers (centrifugal, screw, and scroll)
• Cooling towers, pumps, strainers, separators, and expansion tanks
