Humidity is a big deal when it comes to a healthy indoor environment. Seasonal changes in humidity can be the cause of high or low indoor humidity levels.

When indoor humidity is high, you can end up with health problems related to respiratory infections, asthma and allergies, and the house can have mold growth problems that can even lead to structural damage. When indoor humidity is low, you can end up with a different set of health problems related to increased exposure to bacteria and viruses. The structure of a house doesn’t suffer much from low humidity levels, but wood floors and other natural materials can shrink and crack as they dry out. Obviously, neither situation is ideal.

Many homeowners are looking for ways to improve indoor health, promote home comfort, and avoid allergy and asthma triggers with clean indoor air. Zehnder heat recovery ventilators (HRVs) and energy recovery ventilators (ERVs) promote healthy home air by exhausting pollutants and excess moisture while supplying fresh, filtered air.Properly commissioning an HRV or ERV is essential for optimum system operation.

In fact, improperly installed or commissioned ventilation systems are significantly less effective in improving home air quality. Imbalanced systems can decrease the efficiency of an HRV from around 90 percent to around 60 percent, resulting in four times more energy loss. Commissioning a Zehnder system with a trained professional can promote the life of the system and reduce operating costs for years to come!Why Commission a Zehnder HRV?
