Commercial Centrifugal Chiller Service in Calabasas

When uptime, efficiency, and occupant comfort are mission‑critical, you need a chiller partner who understands the entire plant—compressors, drives, controls, hydronics, and the building they serve. #1 AC Guys delivers end‑to‑end commercial centrifugal chiller solutions in Calabasas, built on 80+ years of engineering experience and four generations of family craftsmanship. Our mission is healthy air and stable, efficient cooling for healthier, more productive buildings.

What We Service & Support

We support single‑chiller sites and multi‑chiller plants across offices, retail, hospitality, healthcare suites, education, and mixed‑use properties. Our team is trained at the manufacturers’ factories of Fujitsu (Japan), Mitsubishi Elektrik (Thailand), Midea (China), Gree (China), and Hier (China), and we service all major centrifugal chiller makes commonly found in Southern California facilities.

• Centrifugal chiller diagnostics, repair, and overhaul
• Start‑ups, commissioning, and seasonal optimization
• Water‑side services: tube cleaning, eddy‑current testing, leak remediation
• Oil and refrigerant analysis, purge unit service, bearing and seal work
• VFD tuning, soft‑starter optimization, and control retrofits
• Integration with BMS and plant sequencing

Deep‑Dive Diagnostics

We resolve chronic issues at the root to prevent repeat failures. Our engineering‑driven approach combines field instrumentation with data trending to validate every fix.

• Vibration analysis and impeller balance checks
• Laser alignment and motor megger testing
• Approach temperature, lift, and capacity verification under load
• Oil acidity, metals, and moisture analysis for early warning
• Refrigerant sampling, leak detection, and charge optimization
• Control logic review, safeties verification, and sensor calibration

Results are documented with clear before/after metrics so you can see the performance gains and risk reduction in writing.

Preventive Maintenance Program

Our PM plans are tailored to Calabasas climate, your load profile, and Title 24 goals. We focus on reliability and efficiency—reducing emergency calls and energy waste.

• Quarterly inspections with trending of approach temps and kW/ton
• Condenser and evaporator tube cleaning, as needed by fouling index
• Eddy‑current testing on a strategic schedule to extend heat‑exchanger life
• Oil and filter changes per condition, not just calendar, to cut cost
• Strainer service, purge unit checks, and refrigerant management logs
• Cooling tower coordination: water treatment alignment and setpoint tuning

Expect a clean, consistent chilled‑water supply that supports healthier indoor air quality and stable humidity for occupant comfort.

Repairs & Overhauls

From minor seal leaks to major component replacement, we execute repairs with precision and clear timelines.

• In‑place tube repairs and tube bundle services
• Seal, bearing, and motor work with OEM‑grade components
• Control board and sensor replacements, recalibration, and trending
• VFD and soft‑starter diagnostics, harmonics mitigation, and tuning
• Legacy refrigerant system updates and responsible recovery

We plan around your schedule to protect critical operations, offering night or weekend windows when needed.

Retrofits, Controls & Energy Projects

Modern controls and right‑sized retrofits can deliver double‑digit energy savings and better comfort. We prioritize measures with the strongest ROI.

• Plant re‑sequencing, demand‑based setpoints, and reset strategies
• VFD optimization on compressors, condenser fans, and pumps
• Advanced sensors and analytics for predictive maintenance
• Heat‑recovery strategies and waterside economizer opportunities
• Low‑GWP refrigerant conversions where appropriate (e.g., R‑513A, R‑1234ze)

All work is documented to support utility incentives and compliance reporting. We keep your stakeholders informed with clear, actionable data.

Compliance, Safety & Documentation

We align with industry best practices and California requirements to keep your plant audit‑ready and safe.

• Title 24‑minded tuning and reporting
• ASHRAE‑aligned maintenance procedures and checklists
• EPA refrigerant management: leak checks, recovery, and logs
• Lockout/tagout and jobsite safety protocols
• Commissioning and retro‑commissioning documentation

You receive detailed service records, performance snapshots, and recommendations that make budgeting and capital planning straightforward.
