One of the most important aspects of indoor air quality is mechanical ventilation, and yet many HVAC contractors still do not sell or install it. This needs to change! As HVAC distributors and sales reps, it is our job to teach contractors the benefits of selling mechanical ventilation. By doing so, we can help improve the indoor air quality for homeowners and office workers alike. Not only does mechanical ventilation help to remove contaminants from the air, but it also helps to regulate temperature and humidity levels. In other words, it is a win-win for both contractors and their customers. So let's make it our mission to promote mechanical ventilation among HVAC contractors. It's good for business and it's good for public health.
