Does an Air Exchanger Require a Lot of Maintenance?

Does an Air Exchanger Require a Lot of Maintenance? – Comprehensive Guide by AirGreen

When it comes to maintaining healthy indoor air quality in your home, air exchangers are invaluable allies. These systems ensure a constant flow of fresh air while removing stale and polluted air from your home. However, like any other household appliance, the efficiency of an air exchanger largely depends on appropriate maintenance. So, does an air exchanger require a lot of maintenance? We will tackle this question in-depth in this article.

Understanding the Importance of Air Exchanger Maintenance

The importance of regular and adequate maintenance of your air exchanger cannot be overstated. A well-maintained air exchanger not only operates more efficiently but also extends its lifespan, saving you money on long-term replacements.

Maintenance of an air exchanger is not only essential for the functioning of the appliance, but also for the health of those living in the house. A poorly maintained air exchanger can become a source of indoor air pollution, counteracting its initial purpose of providing fresh and clean air.

What is the Level of Maintenance Required by an Air Exchanger?

Now that we understand the importance of maintenance, let's address the main question: does an air exchanger require a lot of maintenance? The answer to this question largely depends on the type of air exchanger you have installed and its usage.

As a general rule, air exchangers do not require intensive maintenance, but rather regular and consistent upkeep. Typical maintenance tasks may include:

  • Filter Cleaning: The filters of the air exchanger need to be cleaned regularly to ensure efficient operation. This can be as simple as vacuuming the dust and debris from the filters.
  • Duct Inspection: It is essential to inspect the ducts of the air exchanger to ensure they are clean and clear.
  • Fan Checking: The fans of the air exchanger need to be inspected to ensure they are working correctly.
  • Core of the Exchanger Control: The core of the exchanger, the place where indoor and outdoor air cross, must be checked to ensure it is not obstructed.

Scheduling Your Air Exchanger Maintenance

At AirGreen, we recommend scheduling the maintenance of your air exchanger at least twice a year, typically in spring and autumn. This ensures that the device is ready to operate efficiently during the warmest and coldest months of the year in Montreal.

If your air exchanger is used more intensively, for example, if you live in a larger home or have specific air quality needs, more frequent inspections may be necessary.


While air exchangers require regular maintenance to ensure their optimal operation, this should not be perceived as a chore. In fact, the required maintenance tasks are usually straightforward and can be carried out by homeowners themselves. However, for deeper inspections or if you are not comfortable maintaining the appliance, it is always recommended to call a professional.
