What to Do If Your Building’s Chiller Isn’t Working: A Guide for Greensboro, NC Facility Managers
When your building’s chiller
stops working, the impact can be immediate and severe—especially during Greensboro’s hot and humid summers. Whether you manage an office, healthcare facility, or retail center, a malfunctioning chiller means discomfort, possible equipment damage, and unhappy tenants or customers. Here's a practical guide on what to do if your chiller breaks down, and how to find reliable Commercial HVAC repair
in Greensboro, NC.
Step 1: Check the Basics
Before calling for emergency service, there are a few things you can check:
Power Supply: Ensure the unit is receiving power and that no breakers have tripped.
Thermostat and Controls: Verify that settings are correct and that there are no display errors or alarms.
Airflow Restrictions: Check for blocked vents or dirty air filters, which can trigger a system shutdown.
Water Flow Issues: For water-cooled chillers, ensure the condenser water system is circulating properly.
If nothing obvious stands out, it's time to bring in the professionals.
Step 2: Contact a Trusted Commercial HVAC Contractor in Greensboro
Don't let a malfunctioning chiller
disrupt your business operations. It's essential to call a licensed contractor who specializes in Commercial HVAC services and understands the complexity of chilled water systems.
At SBS-NC, LLC, we’ve been providing fast, expert Commercial HVAC repair in Greensboro, NC since 1991. Our team of certified technicians can quickly diagnose and repair your chiller system, restoring comfort and efficiency.
Step 3: Schedule a Professional Diagnosis
A trained HVAC technician will inspect:
Refrigerant
Levels: Low refrigerant due to a leak can cause the chiller to shut down or operate inefficiently.
Compressors
and Condensers: These critical components can fail due to age or lack of maintenance.
Sensors and Control Boards: Faulty electronics often cause operational failures that require precise troubleshooting.
Pumps and Valves: Malfunctioning hydronic components can affect system pressure and flow rates.
Getting a thorough diagnosis from a commercial HVAC expert ensures that repairs are effective—and not just temporary fixes.
Step 4: Consider Preventative Maintenance
Chillers
are complex systems that require regular upkeep. Once the issue is resolved, ask your contractor about ongoing Commercial HVAC services such as:
Seasonal inspections
Performance testing
Coil and filter cleaning
Vibration and refrigerant leak
checks
A proactive maintenance
plan can prevent future downtime and extend the life of your system.

is more than 15–20 years old and repairs are becoming frequent or costly, it may be time to consider replacement.
