Common Commercial HVAC Issues We Solve
A disruption in your heating and cooling can stem from a wide range of issues. Our technicians have seen it all and are equipped with the diagnostic tools and expertise to pinpoint the root cause of the problem, not just treat the symptoms. We routinely handle complex repairs for Chula Vista businesses, including:
- Complete System Failure: The unit will not turn on, leaving your facility without heating or cooling.
- Insufficient Cooling or Heating: The system is running, but it cannot reach the desired temperature, leading to uncomfortable conditions.
- Strange Noises or Vibrations: Grinding, squealing, or banging sounds often indicate serious mechanical problems, such as a failing motor or worn-out belts.
- Refrigerant or Water Leaks: Leaks can signal a compromised coil or drain line, reducing efficiency and potentially causing significant water damage.
- Electrical and Control Malfunctions: Faulty wiring, failed capacitors, or malfunctioning thermostats can prevent your system from operating correctly or safely.
- Poor Airflow: Clogged filters, blocked vents, or issues within the ductwork can restrict airflow, straining your system and diminishing air quality.
- Frequent System Cycling: A system that turns on and off too frequently is a classic sign of an oversized unit, a thermostat issue, or a clogged filter.
We Service All Types of Commercial HVAC Systems
The complexity of commercial HVAC equipment requires specialized knowledge. Unlike residential units, commercial systems are larger, more powerful, and often integrated into the building’s infrastructure. Our team is factory-trained and highly experienced in servicing the full spectrum of commercial heating, ventilation, and air conditioning equipment found in Chula Vista properties.
Our expertise includes:
- Rooftop Packaged Units (RTUs): These all-in-one systems are common in retail centers, single-story offices, and industrial buildings. We are proficient in repairing all major brands and configurations.
- Commercial Split Systems: Ideal for smaller commercial spaces, these systems require a precise understanding of both the indoor and outdoor components for effective repair.
- Chillers and Cooling Towers: We have deep expertise in repairing the complex water-cooled systems used in large office buildings, medical facilities, and industrial plants.
- VRF and VAV Systems: Variable Refrigerant Flow and Variable Air Volume systems offer incredible efficiency but demand advanced diagnostic skills. Our technicians are experts in troubleshooting their intricate control systems and components.
- Commercial Boilers: For reliable heating, a functional boiler is essential. We provide expert boiler repair services to keep your facility warm and operational through the cooler months.

Protecting Your Investment with Preventative Maintenance
