Expert commercial kitchen hood fabrication and installation for San Antonio restaurants, food service facilities, and commercial kitchens. LG Mechanical specializes in custom-built ventilation systems including Type I grease hoods, Type II steam hoods, exhaust ductwork, and complete kitchen ventilation solutions. As a Master HVAC Contractor with 30+ years of commercial kitchen experience, we design and fabricate code-compliant hood systems that pass health department inspections, ensure food safety, meet fire codes, and keep your San Antonio restaurant operating efficiently and legally.
Commercial kitchen ventilation is critical to restaurant operations—proper hood systems remove smoke, grease, heat, and steam while preventing dangerous grease buildup and fire hazards. LG Mechanical doesn’t install generic, off-the-shelf hoods. We custom-fabricate kitchen ventilation systems built to your exact kitchen layout, cooking equipment, and San Antonio health department requirements. Our comprehensive commercial hood services include on-site fabrication, NFPA 96 code-compliant installation, make-up air system design, exhaust fan sizing, fire suppression integration, and complete documentation for health inspections. We work with new restaurant construction, kitchen remodels, equipment upgrades, and existing hood replacements throughout San Antonio’s diverse food service industry.
Our veteran-owned company brings precision engineering and commercial kitchen expertise to every hood installation. We understand that downtime costs restaurants thousands in lost revenue—that’s why we provide efficient installations with minimal business disruption, often working nights and weekends to meet your opening deadlines. From food trucks and small cafes to large restaurant kitchens and commercial cooking facilities, LG Mechanical delivers professional kitchen hood solutions that protect your business, satisfy health inspectors, and provide reliable ventilation for years of safe food service operations.

LG Mechanical custom-fabricates commercial kitchen hoods on-site for your exact specifications and kitchen layout. Unlike contractors who install generic pre-made hoods that never quite fit properly, we bring metal fabrication equipment directly to your San Antonio restaurant to build ventilation systems matched precisely to your cooking equipment, ceiling height, and space constraints. Our custom fabrication capabilities allow us to create Type I grease hoods and Type II steam hoods in any size or configuration—from small single-line cooking setups to large multi-station commercial kitchens. We fabricate hoods for gas ranges, char-broilers, fryers, griddles, ovens, steamers, and any commercial cooking equipment requiring ventilation. Every hood is built from commercial-grade stainless steel with proper slopes for grease drainage, welded seams for fire safety, integrated grease cups, sealed electrical connections, and professional finish that matches your kitchen aesthetics. Custom fabrication ensures optimal capture efficiency, code compliance, and long-term durability.
Commercial kitchen hood installations must meet NFPA 96 fire safety codes—the national standard for ventilation control and fire protection in commercial cooking operations. LG Mechanical’s Master HVAC Contractor brings expert knowledge of NFPA 96 requirements to every San Antonio restaurant hood installation. We ensure code-compliant construction including proper clearances from combustibles, UL-listed hood construction, minimum 18-gauge stainless steel, welded joints and seams, grease duct slope requirements (minimum 1/4 inch per foot), accessible grease removal points, proper fire suppression system integration, and approved exhaust fan installation. Our installations pass fire marshal inspections because we build hood systems correctly from the start—using code-compliant materials, proper construction methods, and thorough documentation. We also coordinate with fire suppression contractors to integrate Ansul or other fire suppression systems, ensuring your complete kitchen fire protection meets all safety requirements.
Effective commercial kitchen ventilation requires more than just a hood—it needs properly designed exhaust ductwork, adequate exhaust fan capacity, and balanced make-up air to replace exhausted air. LG Mechanical designs complete kitchen ventilation systems for San Antonio restaurants including custom exhaust ductwork fabrication with proper slope and grease drainage, exhaust fan sizing based on cooking equipment BTU output and hood type, make-up air unit installation to prevent negative pressure problems, proper ductwork routing to rooftop exhaust termination, grease duct access panels for required cleaning, and complete system balancing for optimal performance. Many restaurants experience problems from improperly designed ventilation—exhaust fans that can’t overcome building pressure, make-up air systems that create uncomfortable drafts, or undersized ductwork that restricts airflow. Our engineering approach calculates required CFM (cubic feet per minute) based on your specific cooking equipment, designs duct sizes to handle exhaust volume, and ensures proper air balance so your kitchen maintains comfortable working conditions while effectively removing smoke, grease, and heat.
San Antonio Metropolitan Health District requires proper commercial kitchen ventilation for all food service permits—failed hood inspections delay restaurant openings and threaten existing operations. LG Mechanical ensures your commercial kitchen hood passes health department inspections the first time. We provide complete installation documentation including equipment specifications, NFPA 96 compliance certification, as-built drawings showing hood placement and ductwork routing, exhaust fan performance data, make-up air system specifications, and professional certification of code-compliant installation. Our experience working with San Antonio health inspectors means we know exactly what documentation they require and what installation details they examine. We also coordinate inspection scheduling, attend inspections with you, and address any inspector questions or concerns. For existing restaurants facing hood-related violations, we provide expert assessment, correction plans, and professional repairs or upgrades to bring your kitchen ventilation into compliance and protect your food service permit.
When your commercial kitchen hood system fails, every hour of downtime costs your San Antonio restaurant money and potentially violates health codes. LG Mechanical provides emergency commercial hood repair services to get your kitchen back in operation quickly. We diagnose and repair exhaust fan failures, damaged ductwork, grease buildup causing fire hazards, failed fire suppression systems, broken hood lighting, damaged filters and grease cups, and ventilation problems affecting kitchen air quality. Our veteran-owned company responds quickly because we understand restaurant operations can’t wait—a non-functioning hood means you cannot legally operate your kitchen. We maintain relationships with parts suppliers for fast component replacement and keep common repair materials in stock for immediate service. Beyond emergency repairs, we provide preventive maintenance programs that catch problems before they cause shutdowns, scheduled filter cleaning and replacement, exhaust fan belt and motor maintenance, and regular inspections to ensure your hood system maintains health department compliance year-round.
