In an increasingly competitive business environment, the capacity to control air quality in the workplace becomes more than a matter of comfort. The higher your payroll, the higher the down-time costs related to insufficient fresh air and undesirable temperature and humidity levels brought about by deficient systems.

The cost of air-conditioning equipment in commercial and industrial buildings can reach into the hundreds of thousands of dollars. Properly maintained, these systems can without difficulty exceed their average design life, which can range in the order of 15 years for small modular units to 25 years for large custom-built systems. Proper maintenance can reduce real annual depreciation costs by half and eliminate unexpected and unnecessary breakdowns.
