Commercial Centrifugal Chiller Maintenance in Calabasas

When uptime matters, proactive centrifugal chiller maintenance pays off. We stabilize capacity, reduce kW/ton, extend equipment life, and help maintain consistent comfort across offices, retail centers, schools, hospitality, and medical spaces in Calabasas. Our engineering‑first approach blends precise measurements with practical service that fits your operating hours and budget.

What’s Included in Our Centrifugal Chiller PM

• Compressor and motor health checks, vibration baselining, and alignment verification
• Oil sampling with lab analysis (viscosity, acid number, particulates) and filter replacement
• Refrigerant sampling and moisture indicators; leak inspection and documentation
• Condenser/evaporator tube inspection, brushing or chemical cleaning as needed
• Approach‑temperature trending (condenser and evaporator) and performance benchmarking
• Controls calibration, sensor verification, safeties testing, and setpoint optimization
• VFD inspection (where equipped), starter contact checks, and electrical tightening
• Purge unit inspection (if applicable), run hours logging, and non‑condensables management
• Pump, strainer, and seal checks plus chilled/condenser water flow verification
• Cooling tower check (fans, basins, drift eliminators) and water treatment coordination

Every visit concludes with a clear, actionable report: findings, photos, trend data, and prioritized recommendations. You see what we see, so you can plan repairs, budget replacements, and document performance improvements.

Predictive Diagnostics and Reporting

Beyond standard PM, we focus on the metrics that forecast risk. We track kW/ton, pressure differentials, approach temperatures, and delta‑T across coils, while comparing to your historical baselines. Abnormal vibration signatures, rising oil acidity, or a slowly degrading approach indicate fouling or mechanical wear long before a failure. This lets us schedule targeted service during low‑impact windows, not during a heat wave.

Our logs are structured for quick decision‑making. Need a simple executive summary for stakeholders? You’ll get that, alongside detailed data for your facility team. Where small improvements add up—like condenser water setpoint strategies tied to outdoor wet‑bulb—we’ll note them, plus the expected energy impact.

Water‑Side Optimization for Calabasas Conditions

Calabasas sees hot, dry summers and coastal influence via Malibu Canyon. We tune tower operation, verify treatment effectiveness, and target condenser approach to keep efficiency high as weather swings. Clean tubes and balanced water chemistry can save significant energy and reduce compressor loading.
When required, we coordinate advanced tube testing (such as eddy‑current) and partner with your water‑treatment vendor to align chemistry, filtration, and tower cycles of concentration.

Indoor Air and Mission‑Critical Comfort

Our mission is healthy indoor air for healthy living. Stable chilled water enables correct humidity and temperature control at your air handlers, supporting filtration efficiency and occupant comfort. For facilities sensitive to heat or humidity excursions—medical suites, labs, or data rooms—we design maintenance intervals to reduce risk and maintain steady conditions.

Energy, Compliance, and Budget Planning

Well‑maintained chillers operate closer to design efficiency, supporting Title 24–driven energy goals and internal sustainability metrics. We identify low‑cost optimizations first, then plan capital items (e.g., controls upgrades, VFDs, or tower refurbishments) when ROI makes sense. Need documentation for audits or benchmarking? Our reports help demonstrate maintenance diligence and performance progress.

Local Expertise in Calabasas and the West Valley

From the Calabasas Park area to offices near The Commons and along Parkway Calabasas, we understand local load profiles, wildfire smoke seasons, and after‑hours retail schedules. We coordinate access cleanly, protect finishes, and leave mechanical rooms organized so your team can work efficiently between visits.

Industries We Support

• Corporate offices and campuses
• Retail centers and mixed‑use properties
• Hospitality and entertainment venues
• Healthcare clinics and medical office buildings
• Private schools and higher education
• HOA common facilities and amenity centers

Whether you manage a single mid‑rise or a multi‑building portfolio, our program scales. We can align service windows with tenant needs and coordinate closely with your facility director or property manager.

Maintenance Plans Built Around Your Facility

Choose seasonal start‑up/shutdown service, quarterly PM, or a custom plan with priority response options. We map tasks to your equipment list—chillers, towers, pumps, AHUs—and lock in a schedule that minimizes disruptions. If sensors are missing or unreliable, we can recommend cost‑effective upgrades to improve monitoring and catch issues earlier.
