What is an Air Exchanger?

An air exchanger, also known as an air-to-air heat exchanger, is a device used in home renovation to improve indoor air quality. It works by exchanging stale indoor air with fresh outdoor air, while also recovering heat in the process.

How does an Air Exchanger work?

Air exchangers use a series of fans to draw in fresh outdoor air and expel stale indoor air. As the two air streams pass each other, heat is transferred from the warmer air to the cooler air, making it more energy-efficient than simply opening a window.

Benefits of using an Air Exchanger

One of the main benefits of using an air exchanger is the improvement in indoor air quality. By constantly bringing in fresh air from outside, it helps to reduce the build-up of pollutants, allergens, and moisture inside the home.

Types of Air Exchangers

There are two main types of air exchangers: heat recovery ventilators (HRVs) and energy recovery ventilators (ERVs). HRVs transfer heat between the two air streams, while ERVs also transfer moisture, making them ideal for humid climates.

Installation of an Air Exchanger

Installing an air exchanger typically involves cutting a hole in an exterior wall for the unit to be mounted. Ductwork is then used to connect the unit to the rest of the HVAC system, allowing for the exchange of air to take place.

Maintenance of an Air Exchanger

Regular maintenance of an air exchanger is important to ensure it continues to operate efficiently. This includes cleaning or replacing filters, checking for any blockages in the ductwork, and inspecting the fans for any signs of wear and tear.

Cost of an Air Exchanger

The cost of an air exchanger can vary depending on the size and type of unit chosen, as well as the complexity of the installation. However, the energy savings and improved air quality it provides can make it a worthwhile investment for many homeowners.

Conclusion

In conclusion, an air exchanger is a valuable addition to any home renovation project, offering improved indoor air quality and energy efficiency. By understanding how it works and the benefits it provides, homeowners can make an informed decision about whether to install one in their own home.
