Frequently Asked Questions

What is the biggest factor driving high energy costs in a commercial HVAC system?

The biggest factor is typically poor system maintenance, leading to decreased efficiency due to dirty coils, clogged filters, and worn components that force the unit to run longer and harder.

How often should commercial HVAC filters be changed compared to residential ones?

Commercial filters generally need to be checked and changed quarterly or even monthly due to the higher volume of airflow and more rigorous operating schedules.

What are common commercial HVAC safety checks performed during maintenance?

Safety checks include verifying proper combustion/ventilation, inspecting electrical connections and wiring for wear or hazards, and ensuring adequate refrigerant levels to prevent system failure.

How is a refrigerant leak typically detected in a large commercial system?

Technicians use specialized tools such as electronic leak detectors and often a process of applying fluorescent dye into the refrigerant system to visually pinpoint the exact location of the leak.
