The principles of building environment design are generally established by the International Organization for Standardization. According to ISO, a reputable HVAC service should maintain design industry standards in air quality control, for safety and comfort, throughout all phases of the system design process.
Typically, HVAC engineers are members of the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE), and EPA Universal CFC certified. Alternatively, engineers can be state certified. Most HVAC organizations participate in ASHRAE because it is a global society that aims to benefit from the shared cooperative bank of knowledge and technical expertise of its HVAC members. The most acceptable and recognized standards are based on ASHRAE data. Additionally, HVAC contractors are members of NADCA, whose mission focuses primarily on developing quality companies, who perform a high quality of customer service. Learning that your potential HVAC contractor is a member of these organizations should bode well in assuring you of their reputable service.
Granted, all the technical jargon, titles, certifications and licensing requirements become cumbersome and, perhaps, overwhelming. So, begin your quest for a local commercial HVAC service by asking for several customer recommendations from your potential contractor. Can the company show proof of organizational memberships and certifications? Do that maintain Worker’s Compensation and General Liability business insurance coverage? How does the company rate in compliance with OSHA standards and are safety requirements implemented? It is always a good idea to check with your city and state official to ensure that the contractor is properly licensed to do the work they are planning to perform. Asking these questions will help in your selection of a top commercial HVAC contractor to handle your commercial HVAC system maintence, service and repair, retrofit or new installation project.
