Six Core Services


General Contracting for Large-Scale Air Conditioning, Refrigeration, and Ventilation Projects

We specialize in turnkey HVAC projects for all types of commercial, industrial, and specialized low-temperature facilities. We work closely with our clients to meet their specifications and budget requirements, providing full-cycle project management that encompasses “professional design, equipment installation, and precision commissioning” until the entire project achieves peak performance and is successfully handed over.

Renovation and Upgrade of Air Conditioning and Ventilation Systems

We provide services to support office and retail space renovations or interior layout modifications. We handle the structural modifications, ductwork adjustments, installation of additional air vents, and equipment upgrades for our clients’ existing air conditioning and ventilation systems based on their actual needs, achieving maximum operational efficiency at the lowest possible cost.

Year-Round Maintenance and Repair of Buildings, Shopping Malls, and Commercial Facilities

We provide annual maintenance contracts for the air conditioning and ventilation systems of entire commercial buildings, large shopping malls, office towers, and restaurant chains. Through professional inspections and component checks, we prevent problems before they arise, creating a consistently comfortable, efficient, and stable work and business environment for our clients.

Design and Installation of Various Types of Air Conditioning and Ventilation Systems

Our licensed team provides professional airflow and air conditioning layout design services. Our scope of services includes: central air conditioning (chillers), large-scale duct systems, multi-split (VRV/VRF) inverter air conditioning systems, split-type units, and kitchen exhaust systems, ensuring proper indoor air circulation and a comfortable indoor environment.

Drawing Revision Rules, Annual Ventilation Inspections, and Statutory Certifications

We specialize in the statutory licensing procedures for the opening and license renewal of restaurants and commercial establishments. Our services include preparing compliance ventilation drawings, conducting on-site inspections, testing fire dampers and ventilation rates, and issuing air conditioning system certificates, Fire Services Department Form F.S.251 certificates, and Class II Certificates of Compliance in accordance with the law.

Professional Deep-Cleaning Service for Air Conditioners

We provide thorough sanitation and cleaning. The process includes: removing the pig cage fan and motor, deep-cleaning the dust filter and drain pan, and unclogging the drain pipe; we consistently use high-pressure water jets and specialized chemical solutions to completely remove stubborn grime and mold from the interior of the unit, thereby improving cooling efficiency.
