As homes are designed and built to be tighter and more efficient than ever before, they often cannot "breathe" on their own any more. And, especially on the commercial side, codes and standards are beginning to mandate ventilation in buildings. As a result, HVAC contractors are turning to various ventilation solutions to exhaust stale air and bring in fresh, healthy air.

Helping Customers Select Adequate HVAC Filtration

In a residential forced-air system, the filter shields HVAC equipment from becoming dirty and damaged while also protecting occupants from problems associated with poor IAQ. Replacing filters regularly and properly can help minimize or even eliminate IAQ concerns, yet many homeowners forget to do it or simply aren't aware they should be changing their filters between maintenance visits. To remedy that, forward-thinking HVAC contractors are training technicians, educating customers, and even providing filter-delivery services on behalf of maintenance customers.

Why Dirt Streaking Occurs Around Vents

Have you ever noticed dirt streaking out of the sides of any of the supply vents on the HVAC systems you service? Dirt streaking on supply vents is a common problem HVAC professionals encounter on a daily basis. The underlying cause is often blamed on the HVAC system's air filtration and is never considered again. In this scenario, no solutions are truly offered, and the streaking often continues. Is it possible there is more to dirt streaking around supply vents than just the quality of the air filter being used?
