Make-up Air

Managing large commercial properties or high-volume kitchens demands precision oversight of your roof membrane assets. We specialize in the deep-dive diagnostic inspection, air balancing, and structural care of rooftop Make-Up Air Units (MAU) and supply fans. Our technicians evaluate complete rooftop configurations to verify that your outdoor air intakes are positioned away from exhaust streams, clear of debris, and operating with perfect fan wheel alignment to ensure a seamless, non-disruptive flow of fresh air down into your building infrastructure.

True kitchen comfort requires a continuous, calculated cycle of fresh outdoor air to displace the intense heat and grease vapors rising off your cooking line. We integrate high-performance evaporative swamp coolers and fresh air supply plenums directly with your Type I grease hoods and Type II vapor hoods. By introducing conditioned, oxygen-rich air exactly where your exhaust line pulls it, we eliminate severe draft issues, protect your dining areas from negative pressure, and maintain strict compliance with local California mechanical codes.

Clean airflow is impossible without proactive filter and cooling pad maintenance. We provide expert preventative maintenance programs for industrial swamp coolers and premium Breezair systems, focusing heavily on the scale removal, water distribution, and filter changes your system needs. Saturated cooling media and clogged intake filters choke your supply fan motors, driving up energy costs and cutting your fresh air volume in half. We swap out worn components, clean water lines, and maximize filtration to keep your air clean and code-compliant.

Mechanical issues don’t wait for business hours, and neither do we. We provide 24/7 emergency repair services to keep your fresh air infrastructure operational through your busiest dining shifts. Utilizing precise diagnostic instruments like professional clamp meters, our technicians trace complex electrical faults inside your air handler control boxes. We rapidly analyze voltage drops, test magnetic contactors, troubleshoot variable frequency drives, and resolve electrical failures to restore your air supply before your kitchen conditions become hazardous.

The cooling capacity of an industrial swamp cooler relies entirely on the condition of its evaporation pads. We supply and install premium, rigid evaporative cooling media engineered for maximum thermal efficiency and water retention. Replacing old, crushed, or mineral-choked pads with advanced, high-airflow blue cooling media prevents restrictions in your fresh air stream. This targeted upgrade slashes energy draws, prevents water carry-over into your ductwork, and ensures maximum temperature reduction across your hot cooking line.

When older air supply infrastructure becomes uneconomical to constantly repair, we execute clean, turnkey equipment changeouts. We configure side-by-side rooftop ventilation layouts, specializing in ultra-reliable Breezair cooling systems and industrial swamp coolers. Our mechanical team manages the entire process—including structural curb adaptation, water line configuration, and final air-balancing verification. Upgrading to advanced, corrosion-proof fresh air units guarantees steady building pressure and massive utility savings for your commercial property.
