Heat Recovery Ventilators (HRV) & Energy Recovery Ventilators (ERV) in Nanaimo & Parksville
Starting at $15 a week
An HRV or ERV brings fresh outdoor air into a tightly sealed home while removing stale indoor air, without losing the heat you’ve already paid for. As homes get better insulated and more airtight, indoor air quality drops unless something is actively exchanging it. That’s what these systems are built for.
Coastal Energy installs Carrier ventilation systems across Nanaimo, Parksville, and Qualicum. An Energy Recovery Ventilator (ERV) is typically the better fit for our milder coastal climate, since it manages both temperature and humidity as air exchanges. A Heat Recovery Ventilator (HRV) is better suited to colder, drier regions. Both quietly filter incoming air and remove dust, allergens, and particle buildup, so your home stays fresh without sacrificing the energy efficiency of a well-sealed house.
If your home feels stuffy, has lingering humidity, or you’re noticing more dust and allergens than usual, an HRV or ERV addresses the cause instead of masking the symptom.
Why Carrier Is The Brand We Partner With For Heat Recovery Ventilators (HRVs)
Improved Air Quality
A powerful centrifugal blower replaces stale, unhealthy air with a steady stream of fresh air from outside. Works with your central ductwork to deliver whole home comfort in every room.

What's the difference between an HRV and an ERV, and which one do I actually need?
Great question, and honestly it’s the one we get asked the most. Both units do the same basic job: they pull fresh air in from outside and push stale air out, without just opening a window and losing all your heat. The difference comes down to humidity. An HRV, or heat recovery ventilator, transfers heat between the outgoing and incoming air but doesn’t touch moisture. An ERV, or energy recovery ventilator, transfers both heat and humidity. Here on the coast, where we deal with damp winters and humid summers, we usually recommend an ERV because it helps balance moisture levels instead of drying out your home in winter or letting extra humidity in during summer. If you’re further inland or somewhere with drier, colder winters, an HRV tends to be the better call. Our team looks at your specific home and climate exposure before recommending one over the other, so you’re not guessing.
How much does it cost to have one installed?
It really depends on your home, but I can give you a starting point. Financing through us starts at around $15 a week, and we’ve got 0% interest for 18 months if you’d rather spread the cost out than pay it all up front. The total project cost comes down to things like whether you’ve already got ductwork in place, how accessible your mechanical room is, and which unit size fits your square footage. The best thing to do is book a free estimate. Someone comes out, looks at your actual setup, and gives you a real number instead of a ballpark that might not apply to your house.
Is a heat recovery or energy recovery ventilator required by BC building code?
If you’re building a new home in BC, this isn’t optional. It’s been required under the BC Building Code since 2014. Homes are built tighter and better insulated than they used to be, which is great for your heating bill, but it also means the code requires mechanical ventilation to make sure your indoor air actually gets replaced instead of just recirculating stale air. If you’re in an existing home, especially one built before the 90s, there’s a good chance you don’t have one, or you’ve got an older, underperforming unit that’s been ignored for years. In that case it’s not code-mandated retroactively, but it’s still one of the highest-impact upgrades you can make for air quality and comfort. If you’re doing a renovation that involves re-insulating or air sealing your home, it’s worth having us look at your ventilation at the same time, since tightening up a house without addressing air exchange is exactly what the code is trying to prevent.

How often does it need maintenance, and is that a big hassle?
It’s low maintenance, honestly. The core filters on the intake and exhaust just need a rinse or a swap every few months depending on your household and how much dust or pet hair you’re dealing with, and most of that is tool-free, so it’s something you can do yourself in a few minutes. Beyond that, we recommend having it looked at during a regular HVAC service visit just to make sure everything’s balanced and running the way it should. It’s nowhere near as demanding as people expect.
What's covered under warranty if something goes wrong?
We install Carrier units, and they come with a strong warranty behind them. Depending on registration, you’re looking at either a 10-year parts-only limited warranty or a 5-year parts plus 3-year labor option, and that’s on the original owner for eligible residential installs. We walk you through the registration process after install so you’re not missing out on coverage just because a form didn’t get filled out.
Can this help with allergies or how dusty my house feels?
Yes, and this is one of the best side benefits people don’t expect going in. Because the unit is constantly filtering incoming air and cycling out stale indoor air, it reduces the buildup of dust, allergens, and general indoor pollutants that otherwise just get trapped and recirculated in a tightly sealed home. A lot of our customers with allergies notice a real difference within the first few weeks of having one running.
How long does installation take and will it disrupt my whole day?
For most homes, especially ones with existing ductwork, we’re in and out in a day. If you don’t have ductwork and we’re running new duct for the unit, it can take a bit longer, but we’ll give you a clear timeline before we start so there’s no surprise. Either way, we work efficiently and clean up after ourselves, so you’re not stuck living around construction for a week.
Are there any rebates available right now for installing one of these?
Sometimes, yes, it depends on what’s currently active through FortisBC and provincial programs, and that changes throughout the year. Rather than quote you something that might be outdated by the time you call, we check what’s currently available and confirmed at the time of your estimate, so you get accurate numbers instead of a rebate promise that might not still be valid. Give us a call or book your free estimate and we’ll tell you exactly what you qualify for right now.
