Calculation: 0.35 air changes per hour over the living volume, with 9 ft ceilings. Our estimator sets the exact airflow room by room, following CSA F326.
What it does, in numbers
$14.64
Electricity per year
Less than a 60 W light bulb
Bulbs left on day and night. Same calculation for every line: wattage × 8,760 h × 11.142 ¢/kWh.
Meets the Québec Construction Code everywhere in the province. The Code requires 54% at −25 °C below 6,000 degree-days (Montréal, Laval, Longueuil and both shores) and 60% above that. This unit is rated at 60% at 66 cfm.
Airflow and efficiency: manufacturer's data; airflow at 0.4 in and power draw from the V150E75NT spec sheet. Cost: 15 W over 8,760 h at Hydro-Québec's Rate D second tier (11.142 ¢/kWh).
What you should know about this one
Published, verifiable facts, not brochure claims.
6 inAbove 130 cfm, move up to 6 in ducts
The top collars are 5 in, but the guide recommends 6 in ducting on the 150E75NT/NS units once the required airflow exceeds 130 cfm, to avoid excessive static pressure.
No RECNo recirculation mode on the 150 NT/NS
Venmar's guide states recirculation mode is not offered on the 150 NT/NS units, so this ERV's intermittent mode only alternates 20 min at MIN speed with 40 min on standby (STB setting).
60%What it still recovers at −25 °C
The only efficiency figure that matters for a Québec winter, and the one the Code uses. An efficiency quoted without its temperature means nothing; this one is measured at a test airflow of 66 cfm.
ExhaustIt defrosts by pausing the fresh air for a few minutes
In cold weather, the supply fan stops for a few minutes while the exhaust keeps running, so warm indoor air thaws the core. During the cycle the house is briefly under negative pressure; if you have a fireplace or a naturally vented combustion appliance, mention it to our estimator.
ERVIt moves moisture too, not just heat
An ERV transfers some moisture between the two airstreams. Useful in a house that gets too dry in winter or takes on a lot of humidity in summer. The trade-off: it generally recovers less heat than a comparable HRV.
−9 cfmWhat the ducts cost it
Between a nearly unrestricted test bench (0.2 in) and a real duct system (0.4 in), it drops from 138 to 129 cfm. Most spec sheets show only the first number, precisely because it looks better.
15 WMeasured at the airflow it actually runs at
Its 82% at 0 °C is measured at 36 cfm, the continuous airflow of a typical home. At that setting it draws 15 W, or about 131 kWh a year.
5 yearsThe core warranty
The core does the work and is the most expensive part to replace. Motors and parts: 5 years. We register the warranty in your name at commissioning.
5 inWhat it needs on site
5 in ducts, top connection. It weighs 37 lb, and it needs enough clearance to slide the core out once a year.
What it needs on site
In a condo with no floor drain, or with little ceiling clearance, we usually look at a side-port model instead. Our estimator checks the location, the drain and the duct route before ordering.

Venmar AVS N Series A150E75NT ERV – residential air exchanger 138 CFM with vertical connection
At AirGreen, we know that a comfortable home depends not only on heating or air conditioning. Indoor air quality plays a vital role in daily well-being, especially in modern well-insulated homes where air can quickly become stagnant, humid, or particle-laden.
The Venmar AVS N Series A150E75NT ERV is an energy recovery ventilator designed to ensure effective air renewal in residential homes. With its 138 CFM / PCM airflow at 0.4”, maximum sensible recovery efficiency of 82.0%, vertical connection, and ventilation defrost cycle, this model offers a reliable solution to improve indoor comfort while limiting energy losses.
The Venmar A150E75NT is an excellent choice for homeowners looking for a compact, efficient air exchanger well suited to the realities of homes in Montreal, Laval, Longueuil, the North Shore, and the South Shore.
An effective ventilation solution for Quebec homes
In Quebec, homes are often very well insulated to retain heat during winter and improve energy efficiency. This insulation is beneficial but can also reduce the natural renewal of indoor air.
Without adequate ventilation, humidity, odors, CO₂, fine particles, cooking vapors, and stale air can remain trapped inside. Over time, this can create a feeling of heavy air, moisture buildup, or general discomfort in the home.
The Venmar AVS N Series A150E75NT ERV helps address this issue by exhausting stale indoor air and bringing in fresh air from outside. At the same time, it recovers some of the energy contained in the outgoing air to reduce energy losses.
Unlike simple mechanical ventilation, an ERV not only expels air from the house. It also recovers some of the energy already present in the indoor air, making it a smarter solution for homes located in a climate like Greater Montreal.
Why choose the Venmar A150E75NT ERV?
The Venmar A150E75NT is designed to offer an excellent balance between airflow, efficiency, compact size, and ease of installation. With a capacity of 138 CFM, it is suitable for several residential applications where reliable and constant ventilation is necessary.
Its vertical connection is particularly practical when ducts need to be oriented upwards. This configuration can facilitate the integration of the device in a basement, mechanical room, technical space, or when replacing an old air exchanger already installed with a vertical configuration.
Important point: the right choice of an air exchanger always depends on the home itself. The area, number of occupants, insulation level, humidity rate, duct configuration, and actual ventilation needs must be evaluated before choosing the model.

A flow rate of 138 CFM for reliable residential ventilation
With its flow rate of 138 PCM / CFM, the VRE Venmar A150E75NT offers an interesting capacity for several types of residences. This level of ventilation allows for effective indoor air renewal when the device is properly sized and correctly installed.
A flow rate that is too low may be insufficient to remove moisture, odors, and stale air. Conversely, an overly powerful device may be unnecessarily oversized for some homes. The A150E75NT therefore represents a balanced choice for many residential installations.
At AirGreen, we always assess the actual needs of the home before recommending a model. Good ventilation starts with proper sizing.
Maximum sensible recovery efficiency of 82.0%
The Venmar A150E75NT offers a maximum sensible recovery efficiency of 82.0%. This performance indicates that the device can recover a significant portion of the heat contained in the exhausted air before releasing it outside.
In winter, this recovery is especially useful. It allows fresh air to enter while limiting heat loss. The result is a better-ventilated, more comfortable, and more energy-efficient home.
Good energy recovery is essential to ventilate a Quebec home without unnecessarily wasting the energy already produced by the heating system.
A VRE designed for indoor comfort
The A150E75NT is a VRE, meaning an energy recovery ventilator. This type of air exchanger is designed to recover part of the energy contained in the outgoing air before it is expelled outside.
In a well-insulated house, a VRE helps maintain better indoor balance. It helps bring in fresh air, expel stale air, and improve the overall comfort of the home.
This type of device is especially interesting for owners who want to improve ventilation without installing a simple air extraction system that expels indoor air without energy recovery.
Virtuo technology for smarter balancing
The Venmar AVS N Series A150E75NT benefits from Virtuo technology, designed to facilitate airflow calibration and the device’s self-balancing.
Balancing is a very important step when installing an air exchanger. If the incoming and outgoing air are not properly adjusted, performance can be reduced and indoor comfort affected.
Virtuo technology helps maintain a more stable and better-controlled airflow throughout the device’s lifespan. For owners, this means more consistent ventilation. For installers, it allows for more precise and efficient startup.
Built-in LCD screen and convenient diagnostics
The Venmar A150E75NT is also designed to simplify installation, adjustment, and maintenance. Its built-in LCD screen allows selecting the desired airflow and obtaining useful information about the device’s operation.
The integrated diagnostic system is also a significant advantage. It makes it easier to identify certain anomalies or adjustment needs, simplifying checks and helping maintain good long-term performance.
An intelligent air exchanger not only facilitates installation but also maintenance and system monitoring over time.
PMSM ECM motors for reduced consumption
The VRE Venmar AVS N Series A150E75NT is equipped with PMSM ECM motors, designed to provide efficient ventilation with reduced electrical consumption.
These motors maintain reliable airflow while using less energy than a traditional motor. In a home where the air exchanger runs regularly, motor quality is an important factor.
Efficient motors contribute to comfort, system durability, and better operational stability.
Ventilation defrosting: an important function for winter
The ventilation defrost cycle is an important feature for an air exchanger installed in a cold climate like Quebec’s. When outdoor temperatures are low, an air exchanger can be exposed to frost formation.
Defrosting protects the recovery core and maintains proper system operation. This function helps the device maintain more stable performance during cold periods.
For the winters in Montreal, Laval, Longueuil, the North Shore, and the South Shore, well-designed defrosting is essential to ensure reliable and durable ventilation.
MERV 8 filtration to protect the system
The Venmar A150E75NT is designed with MERV 8 filtration, which helps capture certain airborne particles and protect the internal components of the device.
Good filtration helps maintain stable airflow and consistent performance. As with any air exchanger, regular filter maintenance is essential. Dirty filters can reduce airflow, increase motor strain, and decrease overall system efficiency.
At AirGreen, we always recommend checking and cleaning filters according to the actual use of the device and the manufacturer's recommendations.
A convenient vertical connection for multiple configurations
The vertical connection of the Venmar A150E75NT allows for convenient installation in many homes. In some mechanical spaces, ducts must be directed upward rather than sideways. A model with a vertical connection can then simplify duct routing and make the installation cleaner.
This setup is especially useful in basements, mechanical rooms, technical spaces, or replacements of old air exchangers where the existing layout favors a vertical outlet.
At AirGreen, we always check the site configuration before recommending a device. The right model must meet both ventilation needs and installation constraints.
A compact and easy-to-integrate size
With its dimensions of 16.30 × 21.00 × 21.50 in, the VRE Venmar A150E75NT offers a compact size that facilitates integration into many residential environments.
It can suit installations where available space is limited while offering a good ventilation capacity. However, it is important to allow enough clearance around the unit for access to filters, the recovery core, ducts, and internal components.
A well-planned installation makes future maintenance easier and helps extend the air exchanger’s lifespan.
