Commercial rooftop equipment operates under high thermal loads. Our licensed refrigeration and gas technicians resolve critical failures fast to protect tenant comfort and revenue.
Stuck outside air dampers can starve the building of fresh air or force the compressors to overwork during free-cooling conditions, raising utility bills significantly.
Worn or snapped drive belts cause airflow loss instantly, resulting in frozen evaporator coils during summer or heat exchanger limit trips during winter months.
Low refrigerant levels cause long run times and insufficient cooling. We perform precise electronic leak detection and nitrogen pressure testing before recharging.
Annual inspection of gas-fired heat exchangers is vital. A cracked exchanger leaks dangerous carbon monoxide into the airstream and requires immediate licensed repair.
