OSHA estimates that poor indoor air quality costs employers fifteen billion dollars annually due to worker inefficiency and sick days.  Not enough emphasis is placed on indoor air quality and its impact on workforce productivity.  Simply by improving the quality of indoor air, employers can boost performance by up to 10%.  At Lea Heating & Air Conditioning, we recognize the importance of a safe and healthy workplace, and strive to deliver cost-effective and convenient options.

Cleaning products, pest control solutions, personal care products, and even carpets and furniture contribute to degraded air quality.  Printers and copiers emit volatile organic compounds, small particles and ozone.  Computers and other electronics generate heat and accelerate emissions from plastics, circuitry and adhesives used in the design of these products.  It might be impossible to eliminate all potential sources of contaminants, but improving the air you breathe is both simple and feasible.  Through proper ventilation and humidity control, Lea Heating & Air Conditioning can create a healthier, cleaner and more productive work environment for you, your workers and customers.
