HRV Cleaning & Maintenance in Cornwall, Ontario
At SDG Duct Cleaning, we provide professional HRV cleaning and maintenance in Cornwall, SDG and surrounding Eastern Ontario communities.
Your Heat Recovery Ventilator (HRV) plays an important role in your home's ventilation system by exhausting stale indoor air while bringing fresh outdoor air into the home.
Like other HVAC equipment, an HRV requires regular cleaning and maintenance. Filters, the heat-recovery core, fans, drain pan and other components can accumulate dust and debris over time.
At SDG Duct Cleaning, we're HVAC technicians—not just cleaners, so our service goes beyond simply washing the filters.
What Does an HRV Do?
A Heat Recovery Ventilator exchanges stale indoor air for fresh outdoor air while transferring heat between the two air streams.
During the winter, an HRV helps recover heat from the warm air being exhausted from your home before that air is discharged outside.
The incoming and outgoing air streams pass through a heat-recovery core without directly mixing.
Because an HRV is continuously moving air, its filters and internal components require regular cleaning to maintain proper airflow and operation.
Why Does an HRV Need Maintenance?
HRVs are often forgotten because they're usually installed beside the furnace or tucked away in a mechanical room.
However, they're moving both indoor and outdoor air through the unit.
Over time, dust and debris can accumulate on:
- HRV filters
- Heat-recovery core
- Fan blades
- Interior cabinet
- Drain pan
- Intake and exhaust openings
Dirty filters or a dirty heat-recovery core can restrict airflow through the HRV.
Natural Resources Canada recommends cleaning or replacing HRV filters every 1–3 months, inspecting and cleaning the heat-exchange core and condensate system every six months, and general professional servicing annually unless the manufacturer specifies otherwise.
What Is Included in Our HRV Maintenance?
The exact maintenance required depends on the make, model, installation and condition of the HRV.
A typical SDG Duct Cleaning HRV maintenance can include:
- Removing and cleaning the HRV filters
- Removing and cleaning the heat-recovery core as appropriate
- Cleaning accessible fan blades
- Cleaning the inside of the HRV cabinet
- Inspecting and cleaning the drain pan
- Checking the condensate drain
- Inspecting accessible intake and exhaust connections
- Checking the exterior intake and exhaust openings when accessible
- Checking HRV operation
- Inspecting the controls
- Checking for visible problems inside the unit
The manufacturer's cleaning instructions always take priority because different HRV and ERV cores can require different cleaning methods.
HRV Heat-Recovery Core Cleaning
The heat-recovery core is one of the most important components inside an HRV.
As air passes through the unit, dust can accumulate on the core over time.
During maintenance, the core can be carefully removed and inspected. Depending on the manufacturer's instructions, an HRV core may be vacuumed, rinsed or washed before being allowed to dry and reinstalled.
Cleaning methods matter.
Some cores should not be cleaned using harsh chemicals, pressure washers or other aggressive cleaning methods. We follow the appropriate cleaning method for the equipment we're servicing.
HRV Filter Cleaning
Most residential HRVs contain filters on the incoming and outgoing air streams.
These filters protect the heat-recovery core and other internal components from excessive dirt and debris.
They should be inspected and cleaned much more frequently than the HRV itself receives professional maintenance.
The Canada Mortgage and Housing Corporation recommends cleaning or replacing HRV filters regularly and notes that clogged filters can reduce ventilation efficiency and create unbalanced airflow.
If your HRV has washable filters, homeowners can usually perform this basic maintenance themselves by following the manufacturer's instructions.
HRV Condensate Drain Cleaning
Many HRVs produce condensation during operation, particularly during colder weather.
That water needs to drain properly from the unit.
During maintenance, we can inspect the drain pan and condensate drain for visible buildup or blockage and confirm that water can drain properly when applicable.
A blocked condensate drain can allow water to accumulate inside the HRV.
HRV Fan Cleaning
The HRV contains fans that move fresh air into the home and stale air outside.
Dust can accumulate on the fan blades over time.
When accessible and appropriate for the equipment, we clean accumulated material from the fan blades and inspect the fans while the HRV is open.
Don't Forget the Outside HRV Vents
Your HRV has exterior openings for fresh-air intake and exhaust.
Leaves, insects, snow, frost and other debris can sometimes obstruct these openings.
CMHC recommends regularly checking exterior HRV intake and exhaust hoods and removing material that may restrict airflow.
During appropriate HRV maintenance, these openings can also be inspected when they're safely accessible.
How Often Should an HRV Be Maintained?
Different parts of an HRV require maintenance at different intervals.
Filters generally require attention every few months, while the core, condensate system and other components require less frequent cleaning.
For the complete system, having your HRV professionally inspected and maintained approximately once per year is a good general guideline.
Natural Resources Canada's HRV maintenance schedule recommends annual general servicing by a qualified contractor, while individual components require more frequent homeowner attention.
Always follow the maintenance requirements provided by your HRV manufacturer.
Signs Your HRV May Need Cleaning or Maintenance
Consider having your HRV inspected if you're noticing:
- Extremely dirty filters
- Visible dirt inside the HRV
- Reduced airflow
- Unusual noises
- Water accumulating inside or around the HRV
- A blocked condensate drain
- Dirty intake or exhaust openings
- The HRV hasn't been maintained in a long time
Not every HRV problem is caused by dirt. Controls, motors, dampers, sensors and other components can also develop problems.
Because we're HVAC technicians, we can recognize when a problem may extend beyond routine cleaning.
HRV Maintenance by HVAC Technicians
This is one of the biggest differences between SDG Duct Cleaning and someone simply offering HRV cleaning.
We're HVAC technicians—not just cleaners.
An HRV is part of your home's complete heating and ventilation system.
We understand how the HRV interacts with your furnace, ductwork, controls and ventilation system.
If we notice something that doesn't look right during maintenance, we'll let you know.
Combine HRV Maintenance With Duct Cleaning
If you're already having your home's air ducts professionally cleaned, it's a good opportunity to consider the condition of your HRV as well.
Your HRV has its own filters, fans and heat-recovery core, which aren't automatically cleaned simply because your home's main ductwork has been cleaned.
SDG Duct Cleaning can provide HRV maintenance and duct cleaning during the same visit when scheduling allows.
You can also ask us about combining HRV maintenance with furnace maintenance or other HVAC cleaning services.
