Unfortunately, there is no one-size-fits-all solution to mechanical ventilation, so we contacted leading ventilation and indoor-air-quality experts to help you understand HRV- and ERV-based ventilation systems, as well as help narrow down options for an HRV or ERV system that will meet your home’s unique demands. Lennox home ventilation systems in Reinholds, Pennsylvania, provide an energy-efficient option: replacing flat inside air with renewed outdoor air. They’re created to work with any heating and cooling system. Plus, they don’t create any ozone, a toxic gas that can aggravate your lungs. On the installation side, MEV systems require less ducting because air is being drawn one way only: out. With an MVHR system there is a further set of ducting to take the air from the unit into rooms. This also has a direct impact on the level of commissioning required. Commissioning involves marrying the unit’s performance to the actual air flow passing through the valves situated throughout the property. As MEV systems have extract valves only this is a relatively straightforward process, unlike MVHR systems which must balance the extract and supply rates.
