What is the average cost of ventilation hrv erv install in New Brunswick in 2026?

HRV/ERV installation in New Brunswick typically runs $2,500–$5,500 installed, with most mid-range projects landing around $3,000–$3,800 for a standard home. That said, your actual cost depends heavily on whether you're adding a unit to an existing forced-air system or doing a full standalone ducted installation from scratch.

Here's how the pricing breaks down across the market:

Low end ($2,000–$2,800): A basic HRV unit (Lifebreath, Venmar, or equivalent) connected to an existing forced-air furnace in a newer home with accessible ductwork. Labour is minimal when the contractor can tap into existing ducts. More common in post-2000 Dieppe, Riverview, or Hanwell homes where the mechanical room is accessible and the layout is straightforward.

Mid-range ($3,000–$4,200): The most common scenario — a quality unit (Renewaire, Fantech, or Lifebreath 195 ECM range) with some new dedicated ductwork, fresh air intake and exhaust penetrations through the exterior wall or rim joist, and proper balancing. Expect this range for most 1,500–2,500 sq ft homes built in the 1980s–2000s.

High end ($4,500–$6,500+): Full standalone ducted HRV/ERV system with dedicated supply and exhaust runs to multiple rooms — common in older Saint John or Fredericton homes that lack central forced air entirely, or in new builds targeting NBC 2020 Tier 2 compliance where the mechanical design is more complex.

HRV vs. ERV — which one for New Brunswick? This matters more than most people realize. NB's winters are long and cold (regularly -25°C inland), which makes an HRV the standard choice — it transfers heat without retaining excess moisture, which prevents core icing and handles our cold snaps better. ERVs transfer both heat and moisture, making them better suited for dry climates or very tight new builds where you want to retain some humidity. If you're in a newer, well-sealed home in Moncton or Fredericton, an ERV can work well — but your HVAC contractor should do a humidity load assessment first.

On the permit and inspection side, mechanical ventilation systems connected to electrical require a wiring permit through NB Power (1-800-615-0522) if the electrical work exceeds the threshold, and the installation must comply with NBC 2020 ventilation requirements (Part 9, Section 9.32). For new builds submitted after May 1, 2025, Tier 2 energy efficiency applies and controlled mechanical ventilation is a key component of meeting those requirements — worth discussing with your contractor during the design phase.

NB Power rebates are worth checking before you commit to a unit — their Total Home Energy Savings Program has offered rebates on qualifying ventilation equipment in the past, particularly when bundled with insulation or heat pump upgrades. Confirm current eligibility at nbpower.com or call them directly, as program details change year to year.

This is firmly a hire-a-professional job — proper HRV installation requires balancing airflows (typically 0.15 L/s per m² of floor area minimum under NBC), correct exterior penetration placement to avoid recirculation of exhaust air, and electrical hookup. A poorly balanced or incorrectly located unit can actually increase moisture problems rather than solve them.

Your best next step: Get two or three quotes from licensed HVAC contractors in your area — be specific about whether you have existing forced air or not, and ask each contractor whether they'll commission and balance the unit after installation (many skip this step, and it matters). You can find HVAC contractors serving your area through the New Brunswick Construction Network directory.
