Creating a healthy and comfortable living space is essential for every homeowner in Marin, Contra Costa, and Alameda counties. However, our climate in the East Bay can vary significantly throughout the year, making it difficult to find a reliable solution to improving indoor air quality in every season. 

Heat Recovery Ventilators (HRVs) and Energy Recovery Ventilators (ERVs) have become popular in the area because they offer a way to replace unhealthy indoor air with fresh air from outside, all while minimizing energy loss. At Hassler, we offer HRV and ERV installation and specialize in providing building science based solutions for any style of home. 

How Recovery Ventilation Systems Work 

Fresh air exchange systems, like HRVs and ERVs, ensure efficient airflow by drawing in fresh air from outside, filtering pollutants, allergens, and other contaminants in the process. Simultaneously, they expel stale indoor air to remove excess moisture, odors, and airborne pollutants found inside your home, ensuring a healthy living environment. 

Though they operate similarly, HRVs and ERVs have one key difference between them:

  • Heat Recovery Ventilators (HRVs) - A heat exchanger transfers heat from the outgoing indoor air to the incoming outdoor air, pre-conditioning it to match the temperatures and reduce the workload on heating & cooling systems.
  • Energy Recovery Ventilators (ERVs) - In addition to heat transfer, ERV systems also help balance indoor humidity levels by transferring moisture between the incoming and outgoing air. This is achieved through a moisture-permeable layer that extracts moisture from the incoming air in the summers and keeps it inside during the winter.

The Importance of Home Ventilation 

From improving indoor air quality to enhancing comfort and energy efficiency, a well-designed ventilation system can make a significant difference in your daily life. 

  • Air Quality - Ventilation helps remove indoor pollutants, allergens, and moisture to deliver fresh, clean air throughout your home.
  • Health - Home ventilation systems, such as HRVs and ERVs, circulate fresh outdoor air and expel stale indoor air, promoting a healthier living environment.
  • Comfort - Adequate ventilation reduces the likelihood of hot spots, cold drafts, and stuffy rooms—helping you maintain comfortable indoor temperatures and humidity levels year-round.
  • Energy Efficiency - By recovering heat from outgoing air and pre-conditioning incoming air, HRVs and ERVs help reduce usage of your heating & cooling systems.
  • Moisture Control - HRVs and ERVs get rid of excess moisture throughout your home to help prevent moisture-related issues and ERVs also control the moisture of the fresh air that comes inside.
