Are Your HRV Ducts Dirty? Here’s How to Clean Them the Right Way

Living in Nanaimo, we get used to the rhythm of coastal life. The salty breeze, the cedar pollen in spring, the damp winter air; it’s all part of living on Vancouver Island. But those same conditions can put a strain on the air inside our homes. That’s where your Heat Recovery Ventilator (HRV) system comes in.

Here’s the problem: if your HRV ducts are dirty, you’re no longer breathing in fresh, filtered air; you’re recycling dust, allergens, and even moisture that encourages mold. And for many of us, the first sign is subtle: a bit more dust on the coffee table, a stale smell after a rainy week, or even a tickle in the throat that lingers indoors.

At Capital City Power Vacuum, we’ve helped many Nanaimo homeowners who didn’t realize how much their HRV needed attention until things got uncomfortable. So let’s dig into what you can do about it, from how to clean HRV filters yourself to when it’s time for a full HRV duct cleaning.

Why HRVs Are Essential in Nanaimo Homes

Our coastal climate is damp and salty. Houses here are built tight to keep the heat in, but without proper ventilation, moisture builds up fast. That can mean condensation on windows, mold growth in hidden corners, and stale air indoors.

An HRV helps prevent that by:

  • Swapping stale indoor air with fresh outdoor air
  • Recovering heat to keep your energy bills down
  • Reducing indoor humidity

But an HRV can only do its job if it’s clean. Clogged ducts and filters work against you, making the system strain harder while circulating dust and allergens around your home. That’s why HRV duct cleaning should be part of your regular home maintenance.

How Do You Know Your HRV Ducts Need Cleaning?

Not sure if your system is due for a clean? Here are some of the most common signs we see in Nanaimo homes:

  • The air feels stuffy or damp indoors, especially in winter
  • There’s a musty or stale odour coming from the vents
  • You’re dusting furniture more often than usual
  • Family members with allergies or asthma notice flare-ups
  • Your HRV is noisier or seems to be running constantly

If even one of these rings is true, it’s a good idea to take a closer look.

How Often Should You Clean Your HRV?

It depends on your lifestyle, but in general:

HRV Component

Cleaning Frequency

Notes for Nanaimo Homes

Filters

Every 3–6 months

More often, if you have pets or allergies

HRV Ducts

Every 2–3 years

Ocean air brings salt and pollen indoors

Heat Exchanger Core

Once a year

Best done during annual service

Think of it like changing your car’s oil. You might not notice issues right away, but skipping maintenance shortens the life of the system and costs you more in the long run.

How to Clean HRV Filters Yourself

If you’ve never done it before, learning how to clean HRV filters is one of the easiest steps you can take for better air quality.

Here’s how:

  1. Turn off the HRV unit.
  2. Open the access panel.
  3. Slide out the filters; there are usually two.
  4. Rinse them gently under lukewarm water. Avoid hot water or harsh cleaners.
  5. Let them air-dry completely.
  6. Reinstall and close the panel.

This simple task takes less than half an hour and can make a noticeable difference in airflow. Many Nanaimo homeowners schedule it with the change of seasons, right before the cold, damp winters, and again before the spring pollen arrives.

How to Clean HRV Ducts: DIY vs Professional

When it comes to cleaning HRV ducts, things get more complicated. You can do a light refresh yourself, but deeper cleaning requires professional equipment.

Here’s a comparison:

Task

DIY Cleaning

Professional Cleaning (Capital City Power Vacuum)

Vent covers

Remove and wash in soapy water

Included

Visible dust in openings

Vacuum with brush attachment

Full removal deep inside the duct system

Duct interiors

Limited reach, usually first 1–2 ft

High-powered vacuums and rotary brushes reach the entire duct

Airflow improvement

Minimal

Significant, restores efficiency

Allergen removal

Partial

Comprehensive

While doing the basics yourself can be helpful, for a thorough, professional clean, opting for a full service is the way to go.

What We Do During Professional HRV Duct Cleaning

At Capital City Power Vacuum, we follow a careful process to make sure your HRV is cleaned safely and thoroughly:

  1. Inspect the ducts and HRV system.
  2. Seal off areas to prevent dust from escaping.
  3. Connect specialized vacuums to the ductwork.
  4. Use rotary brushes to loosen debris.
  5. Remove dust, pollen, and allergens completely.
  6. Check and clean the HRV core and filters.
  7. Test the system to ensure airflow is back to normal.

It’s a detailed job, but the results are immediate: cleaner air, quieter operation, and better comfort at home.

Everyday Tips to Keep Your HRV in Top Shape

Between professional cleanings, you can keep your HRV running smoothly with a few simple habits:

  • Check and clean filters every few months.
  • Keep the area around the HRV unit dust-free.
  • Inspect outdoor intake and exhaust vents for leaves, snow, or debris.
  • Listen for unusual noises, which can signal blockages.

Staying consistent with small tasks means less build-up in the ducts over time.

FAQs

Most homes benefit from HRV duct cleaning every 2–3 years, depending on factors like pets, smoking, or allergies. Filters should be cleaned more often, every 3–6 months.

You can handle basic tasks like washing vent covers and vacuuming near the openings. But deeper duct cleaning requires specialized equipment. For a full clean, it’s best to hire professionals like Capital City Power Vacuum.

Dirty ducts reduce airflow, make your HRV work harder, and circulate dust and allergens throughout your home. Over time, this can lead to higher energy bills, poor indoor air quality, and even mold growth.

Not when done properly. At Capital City Power Vacuum, we seal off the system and use powerful vacuums to keep dust contained. Most homeowners are surprised by how tidy the process is.

If the filters look grey or dusty, or if airflow feels weaker than usual, it’s time to clean them. Cleaning HRV filters is a simple process that can be completed in under 30 minutes.
