Common Commercial HVAC Issues

December 5, 2025
common commercial hvac issues

Commercial HVAC systems, like any complex mechanical systems, can experience various issues over time.  Addressing common commercial HVAC issues promptly is essential to ensure optimal performance, energy efficiency, and occupant comfort. In this article we discuss common commercial HVAC issues and solutions.

Poor Airflow

Insufficient airflow can result from clogged filters, blocked ducts, or issues with the blower motor. This can lead to uneven heating or cooling throughout the commercial space. Regularly replace or clean air filters as part of commercial HVAC maintenance. Ensure the blower motor is functioning correctly and consider upgrading to more efficient fans if necessary.

Refrigerant Leaks

Leaks in the refrigerant lines can cause a drop in system efficiency and lead to inadequate cooling. Identifying and repairing leaks promptly is crucial for maintaining optimal performance. Conduct regular inspections and address any refrigerant issues to maintain system efficiency. A professional HVAC technician should handle refrigerant-related tasks, contact us for commercial AC repair.

Thermostat Malfunctions

Faulty thermostats can lead to inaccurate temperature readings and improper system operation. Calibrating or replacing thermostats may be necessary to maintain precise temperature control. Consider upgrading to programmable or smart thermostats for better control and energy savings.

Electrical Problems

Electrical issues such as faulty wiring, capacitor problems, or issues with the electrical components of the HVAC system can lead to system failures or malfunctions. Regularly inspect and maintain electrical components. Address faulty wiring, capacitors, or other electrical issues promptly. Schedule regular professional commercial HVAC service to catch potential electrical problems early.

Compressor Failures

The compressor is a critical component of the HVAC system. Overheating, electrical problems, or refrigerant issues can lead to compressor failures, resulting in a lack of heating or cooling. Monitor refrigerant levels and address any imbalances. Regularly maintain and clean the coils. If a compressor failure occurs, consult with a qualified HVAC technician for repairs or commercial HVAC replacement.

Frozen Coils

Freezing coils may occur due to issues such as low refrigerant levels, dirty coils, or problems with the airflow. This can reduce the system's efficiency and hinder its ability to heat or cool effectively. Identify and address the root cause, which could be low refrigerant levels, dirty coils, or airflow issues. Regularly clean and maintain coils to prevent freezing.

Dirty or Clogged Filters

Neglecting to replace or clean air filters regularly can reduce airflow, strain the system, and lead to increased energy consumption. It's essential to maintain clean filters for optimal performance. Establish a routine filter replacement or cleaning schedule. Consider using high-efficiency filters. Regular maintenance helps prevent reduced airflow and system strain.

Uneven Temperature Distribution

Issues with the ductwork, zoning, or system balance can result in uneven temperatures throughout the commercial space. This can affect the comfort levels of occupants. Balance the system and inspect ductwork for leaks or blockages. Consider zoning systems for better temperature control in different areas of the commercial space.

Noisy Operation

Unusual noises such as banging, clanking, or squealing may indicate problems with components like the blower motor, bearings, or belts. Timely identification and repair are essential to prevent further damage. Identify the source of the noise, whether it's the blower motor, bearings, or belts. Replace or repair the affected components. Regular lubrication and maintenance can reduce noise levels.

System Cycling Problems

Rapid or frequent cycling of the HVAC system can be caused by issues with the thermostat, sensors, or improper system sizing. This can lead to increased wear and tear on components. Ensure the thermostat is functioning correctly and is properly calibrated. Address issues with sensors or system sizing. Regularly inspect and maintain the system to prevent cycling problems.
