How much you get
Heat recovery ventilators sometimes appear as an eligible measure inside broader HRSP retrofit packages in other Ontario cities, but we haven't confirmed a specific Guelph rebate amount for HRV on its own. Check the official program directly before budgeting for one.
HRV / ventilation rebate
Our Guelph hub page doesn't have a specific dollar figure for this category yet.
Check the official program directly
Since we don't have a confirmed Guelph-specific number for HRV or ventilation upgrades, your best next step is the official homerenovationsavings.ca program site, or the assessment-required tier described on our Guelph rebate hub, which covers air sealing and several insulation measures that a home energy assessment might bundle alongside ventilation work. We'll update this page as soon as we confirm real numbers for Guelph.

Local context
Utilities: Alectra Utilities (electricity) and Enbridge Gas (natural gas). Alectra took over Guelph's electricity system when Guelph Hydro merged in on January 1, 2019.
Typical heating: Mostly natural gas, which affects which heat pump tier a household lands in.
Permits & timeline: 6–10 weeks quote to installation for solar, faster for a heat pump swap. City building permit and ESA electrical inspection where required.
Understanding your HRV/ERV
An HRV is a box of ducts and a fan pair that does one simple job well: it pulls stale, humid air out of your Guelph home and pushes fresh outdoor air in, while running the two airstreams past each other inside a core that transfers most of the heat from the outgoing air onto the incoming air. Your furnace or heat pump isn't starting from scratch heating freezing intake air — it's topping up air that's already been partly warmed.
The need shows up as a side effect of doing everything else right. Sealing and insulating a Guelph home cuts heating bills, but it also seals in stale air, humidity, and indoor pollutants that used to escape through the building's natural leaks. Mechanical ventilation replaces that lost airflow deliberately, on a schedule you can control.
HRV or ERV — which one
The difference that actually matters when choosing between them: an HRV moves heat only, while an ERV moves heat and moisture together. In a humid climate, or a very cold one where indoor air can get uncomfortably dry in January, an ERV's moisture transfer is usually the better call. A straight HRV tends to suit drier, more moderate climates just fine.
Real-world efficiency, not the marketing number
The honest efficiency picture is a range, not a fixed number. Expect roughly 60-75% heat recovery through moderate cold snaps, falling off in the coldest stretches when the unit needs longer, more frequent defrost cycles to keep its core from icing over — which also means more runtime and slightly less fresh air moving through the house during those stretches.
Should you turn it off in winter?
Homeowners often ask whether it's fine to just turn the HRV off once it gets cold, since the incoming air feels chilly. It isn't, at least not fully off. That chilly-feeling air has already had most of its heat recovered before you feel it — the unit isn't wasting what it looks like it's wasting. Running it on a lower or intermittent setting through winter is the standard professional recommendation; killing it entirely in a tightly sealed home lets humidity build up, which tends to show up first as condensation on windows and can lead to mould if it goes unchecked. It's also worth knowing that an HRV doesn't replace bathroom exhaust fans. The airflow an HRV moves is spread across the whole house on a continuous, modest schedule — it can't clear a steamy bathroom the way a dedicated exhaust fan can, so skipping the fan because the HRV is already running is a mistake worth avoiding.
Checking a unit before you buy
Not every HRV or ERV on the market performs the same, so it's worth checking a unit against Natural Resources Canada's ENERGY STAR certified HRV/ERV products list before you buy — and NRCan's own explainer, "What's a heat/energy recovery ventilator and do you need one?", is a good plain-language starting point if you're new to the category.
Common questions
Is there an HRV rebate in Guelph?
We don't have a confirmed Guelph-specific dollar figure for HRV or ventilation rebates on our hub page. Check the official Home Renovation Savings Program site directly, since this may be bundled into the broader assessment-required retrofit tier rather than offered as its own standalone rebate.
Your utility: Alectra Utilities
Alectra Utilities is the local electric utility for Guelph, since Guelph Hydro merged into Alectra on January 1, 2019. The HRV rebate above comes from a province-wide program, so which utility bills you doesn't change what you qualify for. Where it can matter: Alectra is who to contact about your home's electrical service capacity if your installer flags an upgrade, and who bills the electricity your new equipment uses once it's running. Some utilities layer their own incentive on top of the province rebate — worth a quick call to Alectra to ask directly.
Why ventilation matters more in Guelph's winters
Guelph's average January daily low over the last 10 winters (2015-2024) has been -9.3°C, with a coldest recorded day of -30.8°C. Colder outdoor air holds less moisture, which is exactly why a well-sealed Guelph home needs mechanical ventilation in the first place — without an HRV, that sealed-up house traps humidity indoors instead of exchanging stale air for fresh air without losing the heat you paid for.
