As a business owner or facility manager, it’s crucial to ensure the smooth functioning of your commercial building’s HVAC system. It is responsible for regulating the indoor air quality, temperature, and humidity levels, which, in turn, affects the comfort of your employees and customers. But, what happens when your HVAC system isn’t maintained regularly? The answer is simple – a decline in energy efficiency, a decline in employee productivity, poor indoor air quality, and a shorter lifespan of the equipment.
