Is Your Air Exchanger Working Correctly? A Comprehensive Guide by AirGreen

AirGreen, as a leading HVAC company based in Montreal, often receives inquiries about the performance and functioning of air exchangers. "How can I tell if my air exchanger is working correctly?" is a frequently asked question by homeowners who want to ensure the best air quality in their living spaces. This article provides an in-depth examination of this topic.

Understanding Air Exchanger Functionality

Before delving into the details, it's essential to understand the basic functionality of an air exchanger. An air exchanger works to regulate your home's indoor air quality by replacing stale indoor air with fresh outdoor air. This process involves balancing temperature and humidity levels within the house, contributing to a healthier and more comfortable environment.

Signs of a Properly Functioning Air Exchanger

A well-functioning air exchanger makes a significant difference in your home's air quality and comfort. Here are some key signs that your air exchanger is working correctly:

  1. Stable Indoor Humidity Levels: One of the main roles of an air exchanger is to regulate humidity levels. If your indoor humidity is stable and within a comfortable range (between 30% and 50%), it's likely your air exchanger is functioning correctly.
  2. Lack of Stale or Musty Odors: An efficient air exchanger will effectively ventilate your home, preventing the buildup of stale or musty odors.
  3. Comfortable Indoor Temperature: A properly working air exchanger should help maintain a comfortable indoor temperature by assisting in heating and cooling.
  4. Absence of Condensation on Windows: Excessive window condensation can indicate high humidity levels in the home. If you don't notice this issue, your air exchanger is probably doing its job well.
  5. Reduced Allergy Symptoms: By filtering outdoor air, an air exchanger can reduce allergens in your home. If you or your family members have fewer allergy symptoms, this can be a positive sign.
