ERV & HRV Maintenance

Keep fresh air flowing and energy costs down. We service in-suite energy recovery ventilators (ERVs) and heat recovery ventilators (HRVs) in Toronto condos—filters, cores, motors, and controls—with photo reporting for residents and property managers.

Modern Toronto condos rely on ERVs for ventilation and indoor air quality. Dirty filters and clogged cores block fresh air, increase humidity, and force the unit to work harder. Regular maintenance keeps air quality high and energy recovery efficient.

Fresh air & IAQ focus

Clean filters and cores ensure proper ventilation, reducing stuffiness, odours, and humidity buildup in sealed condo suites.

Energy recovery optimization

A clean core transfers heat efficiently between incoming and outgoing air, cutting heating and cooling costs year-round.

Photo-backed reporting

Filter condition, core status, and airflow notes in the resident and manager portal after every visit.

Our ERV maintenance process

  1. Suite prep & access: Protect finishes, access the unit (ceiling, closet, or mechanical chase), and isolate power.
  2. Filter service: Remove, inspect, and replace or clean supply and exhaust filters.
  3. Core cleaning: Inspect and vacuum or wash the heat/energy recovery core per manufacturer specs.
  4. Condensate care: Clear the drain, inspect the pan, and treat for algae if needed.
  5. Motor & blower check: Inspect fans, bearings, and wheels for dust buildup and vibration.
  6. Controls & airflow: Verify settings, test boost mode, and check damper operation.
  7. Reporting: Upload photos, filter status, and recommendations to the Hudson portal.

Why ERV maintenance matters in Toronto condos

Toronto's building code requires mechanical ventilation in modern high-rises because suites are sealed tight for energy efficiency. ERVs and HRVs bring in fresh outdoor air while recovering heat (or cooling) from exhaust air. Without maintenance, these units can't do their job—and residents suffer from poor air quality, humidity problems, and higher energy bills.

  • Residents: Better air quality, reduced odours, and lower humidity.
  • Property managers: Fewer complaints, program tracking, and compliance documentation.
  • Boards: Summaries, recurring issues, and upgrade recommendations.

What we check

  • Supply and exhaust filters (replace or clean)
  • Heat/energy recovery core (inspect, clean, or flag for replacement)
  • Condensate drain and pan (clear blockages, treat if needed)
  • Fan motors and blower wheels (dust, vibration, noise)
  • Controls, defrost settings, and boost modes
  • Ductwork connections and damper operation

Pricing factors (no surprises)

  • ERV/HRV model, location, and accessibility (ceiling, closet, chase)
  • Filter type and size (standard vs. HEPA, washable vs. disposable)
  • Core condition and cleaning requirements
  • Condensate drain accessibility and treatment needs
  • Bundled suites or building-wide scheduling for managers

Why Hudson for condo ERV service

  • Condo-focused technicians familiar with in-suite ERV/HRV brands and installations
  • Photo and status reporting for residents, PMs, and boards
  • Manager portal for stack scheduling and completion proofs
  • In-suite protection: drop sheets, shoe covers, and post-service wipe-down
  • Toronto & GTA coverage with same-day support for urgent IAQ issues

For property managers & boards

We coordinate building-wide ERV maintenance with resident notices, stack sequencing, and filter inventory. Post-visit summaries include suites completed, filter status, core condition, and any flagged deficiencies. Pair this service with fan coil maintenance or dryer vent cleaning for comprehensive suite care.

Transparent reporting: Every suite gets photo proof and noted issues in the portal for boards and property managers.

FAQs

Most Toronto condo ERVs need filter changes every 3–6 months and full maintenance (including core cleaning) annually. High-dust environments, allergy-sensitive residents, or suites near construction may need more frequent service.

Both bring fresh air in and exhaust stale air out while recovering energy. ERVs (Energy Recovery Ventilators) transfer both heat and moisture, making them ideal for Toronto's humid summers and dry winters. HRVs (Heat Recovery Ventilators) transfer only heat. Most newer Toronto condos use ERVs.

Toronto building code requires mechanical ventilation in modern high-rises because suites are built airtight for energy efficiency. ERVs provide fresh outdoor air while recovering energy from exhaust air, keeping suites healthy and reducing heating/cooling costs.

Yes. A clogged filter or dirty core reduces airflow and can trap moisture inside the suite. In winter, this often shows up as condensation on windows. Regular maintenance keeps humidity balanced.

Yes. We inspect the core during every maintenance visit and vacuum or wash it per manufacturer specs. Heavily soiled cores may need deep cleaning or replacement, which we'll flag and quote.

We stock standard filters for most common condo ERV models and can source HEPA or specialty filters for allergy-sensitive residents. Filter type and size depend on the specific unit installed in your suite.

Absolutely. We run stack-by-stack schedules, send resident notices, manage filter inventory, and provide post-program summaries with completion rates and deficiencies for property managers and boards.

Yes. Every visit includes photos of filters, core condition, and any issues—all uploaded to the Hudson portal for residents and property managers to review.

In most Toronto condos, the in-suite ERV is the owner's responsibility (filters, cleaning, repairs). The condo corporation typically maintains any shared fresh air intake or exhaust systems. Check your building's declaration or ask your property manager.

Yes. We offer after-hours and weekend scheduling for building-wide programs or individual suites. Let us know your building's quiet hours and access requirements.

Yes. Bundling services reduces disruption and often lowers per-visit cost. Many buildings schedule ERV filter changes alongside seasonal fan coil or heat pump maintenance.

Yes. We cover Toronto core and the broader GTA, including Mississauga, Etobicoke, North York, and Scarborough for both individual calls and building-wide programs.
