FAQ
What is an ERV system and how does it work?
An ERV (Energy Recovery Ventilator) is a mechanical fresh air system that continuously exchanges stale indoor air with filtered outdoor air. Unlike a simple fan, a VanEE ERV uses an enthalpy core to recover both heat and up to 70% of indoor moisture from the outgoing air stream — transferring that warmth and humidity into the incoming fresh air. This means you get fresh, oxygen-rich air all winter without freezing drafts or bone-dry indoor conditions.
How is an ERV different from an HRV?
Both ERVs and HRVs (Heat Recovery Ventilators) recover heat from exhaust air to reduce energy loss. The key difference is moisture. An HRV only transfers heat, so it exhausts indoor humidity outside — leaving Toronto homes dangerously dry during winter. An ERV transfers both heat and moisture, keeping indoor humidity in the comfortable 30–40% range year-round. For Toronto's climate — cold, dry winters and hot, humid summers — an ERV is the better all-season choice.
Why do I need a fresh air system if my home already has a furnace filter?
Your furnace filter only traps airborne particles when the system is actively heating or cooling — and it does not bring fresh outdoor air into your home. During Toronto's long winters, homes are sealed tight for months with no fresh air exchange. That traps CO₂, VOCs from furniture and cleaning products, and airborne viruses indoors. An ERV runs independently of your furnace, continuously supplying fresh, filtered air and exhausting pollutants, regardless of whether your furnace is on.
Will an ERV make my home colder in winter?
No. A properly installed VanEE ERV recovers up to 75% of the heat from outgoing air before it leaves your home. The incoming fresh air is pre-warmed by that recovered heat — typically arriving within a few degrees of room temperature. You get fresh air without the cold draft you'd feel from opening a window. Your furnace works less, not more.
Does an ERV help with allergies and asthma?
Yes. An ERV continuously exhausts indoor allergens — pollen, dust mite debris, pet dander, and mould spores — that would otherwise keep circulating inside a sealed home. At the same time, it pre-filters incoming outside air before it enters your living space. Many allergy sufferers notice significant relief within days of ERV installation, especially during Toronto's spring and fall pollen seasons.
How much does it cost to run an ERV year-round?
ERVs are remarkably efficient. The fan motors draw about as much power as a 60-watt light bulb. The real savings come from heat recovery: by capturing warmth that would otherwise escape through bathroom fans or open windows, an ERV reduces heating costs in winter. In summer, it reduces dehumidification load on your air conditioner. Most GTA homeowners find the energy savings offset the operating cost over a full year.
How often do I need to clean or replace the filters?
VanEE ERV filters should be vacuumed or washed every 3 months, and replaced approximately every 6 months — more frequently if you have pets or live near construction. The enthalpy core should be checked annually and cleaned as needed. Filter costs are modest (typically $30–60 per set), and replacement takes under 5 minutes. We walk every client through the simple maintenance routine during installation.
Can an ERV be installed in an older Toronto home?
Absolutely. We install ERVs in homes of every age — from century red-brick Victorians in Leslieville to 1980s back-splits in Scarborough. Our licensed technicians design a custom ducting plan that works with your existing framing, whether you have a basement, crawl space, or attic access. The installation is minimally invasive, and we never cut into load-bearing beams or compromise your home's structure.
How long does installation take, and will it disrupt my family?
A typical full ERV installation takes 1 to 2 days. We drape work areas with protective sheeting, vacuum dust as we work, and keep the disruption to a minimum. Most rooms remain fully usable during the process. You'll have clean, balanced fresh air running through your home by the end of day 2.
Does an ERV also help with basement dampness and musty smells?
Yes — this is one of the most overlooked benefits. Finished basements in Toronto homes often trap moisture and odours because they lack proper airflow. An ERV draws stale, damp air out of your basement while supplying dry, fresh air. Within days, that musty "basement smell" disappears, and humidity levels stabilize — helping prevent mould growth and protecting any renovations you've invested in.
Is an ERV worth it if I already use a dehumidifier and air purifier?
An ERV does what those devices can't — it replaces stale indoor air with fresh outdoor air. A dehumidifier removes moisture but doesn't bring in fresh air. A portable air purifier filters particles but can't remove CO₂ or VOCs. An ERV handles humidity control and air exchange in one integrated system, often allowing you to retire or reduce reliance on standalone appliances — saving floor space and electricity.
