The 3 Fatal Mistakes When Buying an Air Exchanger That Only Experienced Technicians Know

Stop Falling Into the Trap: Choose Your Air Exchanger with Essential Advice from AirGreen

At AirGreen, our years of experience in HVAC installations across Montreal, Laval, Longueuil, as well as the North Shore and South Shore, have enabled us to identify three common mistakes homeowners frequently make when purchasing an air exchanger. These mistakes, unknown to most people, are well understood by our experienced technicians, and avoiding them will ensure an efficient, economical, and beneficial installation for your respiratory health.

Here we detail these three critical pitfalls to avoid, accompanied by concrete solutions to help you make the best possible choice.

Mistake #1: Choosing an Incorrectly Sized Air Exchanger

Selecting an air exchanger suited precisely to your home's size and particularities is essential. Unfortunately, homeowners often make uninformed decisions or are rushed into choosing the wrong-sized model by an unscrupulous salesperson, leading to disastrous outcomes.

Consequences of Incorrect Sizing:

  • Inefficient humidity control.

  • Accumulation of allergens in indoor air.

  • Premature wear of motor and ventilation systems.

  • Unnecessary increases in energy costs.

Real-Life Example in Montreal:

In Montreal, our AirGreen team recently corrected a complicated issue for a client in the Rosemont neighbourhood. This client had installed a Venmar EVO5 500 HRV, recommended by an unqualified salesperson. Upon inspection, we quickly determined that this device, intended for a much larger home, was oversized. We replaced it with a more suitable model (Venmar AVS S10 ERV), delivering optimal performance and significantly reducing the client's energy bill.

Mistake #2: Overlooking Local Climate Specifics

Each region has its own unique climate characteristics. Therefore, an air exchanger that’s ideal for Montreal might not necessarily be the best choice for Longueuil or Laval. Unfortunately, many homeowners choose a device without considering these geographic subtleties, an oversight with significant repercussions.

Why Considering Local Climate Is Crucial:

  • Variations in humidity differ significantly from one region to another.

  • Impacts the device’s performance and durability.

  • Directly affects indoor comfort due to unsuitable choices.

Case Study in Laval:

We assisted a Laval family whose air exchanger consistently produced excessive humidity during winter. After careful analysis, our expert team found the homeowner was using a standard HRV (Heat Recovery Ventilator), whereas the region's high humidity levels required an ERV (Energy Recovery Ventilator). We replaced the unit with a Zephyr ZVP-200 ERV, specifically designed to manage frequent humidity fluctuations in Laval. The result: rapid elimination of excessive humidity problems and a noticeable improvement in family respiratory comfort.

Mistake #3: Ignoring Eligibility for Available Grants

Many homeowners still overlook the fact that they can benefit from substantial grants for purchasing and installing an air exchanger. At AirGreen, we frequently see this omission costing homeowners significant amounts of money.

Advantages Not to Overlook:

  • Significant reductions in total installation costs.

  • Increased return on investment.

  • Easier access to high-performance, energy-efficient devices.

Successful Example in Longueuil:

Our technicians recently assisted a homeowner in Longueuil with the installation of a high-performance air exchanger (Lifebreath RNC155 HRV). By leveraging Hydro-Québec's LogisVert program, the client substantially reduced his initial investment, fully enjoying the energy and health benefits of a top-of-the-line device.
