- Energy bills have increased noticeably without a change in usage or occupancy.
- There are unusual sounds coming from the equipment, such as banging, rattling, or grinding.
- Certain areas of your building are significantly warmer or cooler than others.
- There is a musty, burning, or otherwise unusual odor coming from the vents.
Your system is cycling on and off more frequently than normal. - Airflow has decreased and the space feels stuffy or poorly ventilated.

Common Commercial HVAC Problems We Resolve
Over five decades in the Dallas area, we have seen every type of commercial HVAC issue. Some problems come up repeatedly, particularly given the demands of the local climate. The most common issues we address include:
- Condenser coils clogged with dirt and debris, which reduces the system’s ability to release heat effectively in hot weather.
- Frozen evaporator coils caused by low refrigerant, poor airflow, or a failing blower motor.
- Drainage problems that lead to water damage, mold growth, or system shutdowns.
- Overloaded systems that were undersized for the building or have not been maintained.
- Belt and bearing wear in older equipment that creates noise and reduces efficiency.
- Thermostat and sensor failures that cause the system to behave erratically or run inefficiently.
