Protect Indoor Air With HRV and VAC Cleaning

In modern homes — particularly in cold climates like Calgary — proper ventilation and clean air-delivery systems are more important than ever. Two systems that often get overlooked are the HRV (Heat-Recovery Ventilator) and the Central VAC (central vacuum system). At The Ductibles we offer cleaning and maintenance for both, alongside duct-work, furnace, and other services. Let’s unpack what these systems are, why they matter, and how you can maintain them.

What is an HRV system?

An HRV is designed to exchange stale indoor air with fresh outdoor air while recovering heat from the outgoing air — so you don’t lose energy in the process. It helps reduce stale-air buildup, remove indoor pollutants, and maintain more consistent air quality and humidity levels.

What is a Central VAC system?

A central vacuum system pulls dust, debris, and other pollutants from living areas via in-wall piping to a central collection canister (often in a garage or utility room). Because the motor and exhaust are outside the living space, central VAC systems typically reduce airborne dust compared to portable vacuum units.

Why cleaning these systems matters

• Over time, HRV filters and cores may accumulate dust, mould, or biofilm — reducing ventilation efficiency, spreading stale air, or worse contributing to indoor air-quality issues.
• Central VAC piping can collect blockages, accumulate fine dust, allow motor strain, or cause loss of suction. If left unchecked, it reduces performance and may require costly repairs.
• Because these systems are “behind the walls” they’re out-of-mind but they contribute significantly to the indoor-environment performance of your home.

Maintenance checklist & when to call professionals

For HRV:

• Change or clean filters every 6-12 months (or sooner if you have pets or high dust load).
• Clean the heat-exchange core at least annually.
• Inspect and clean intake/outlet grilles.
• Ensure condensation drainage is clear and functioning.
• For best performance, schedule a professional deep-clean every 2-3 years (or annually in heavy-usage homes).

For Central VAC:

• Empty the collection canister when it’s ~50-70% full (to maintain suction).
• Inspect hose and attachments for blockages or kinks.
• Once a year (or every few years) have the piping inspected/cleaned by a pro (we at The Ductibles can perform this).
• Listen for drop in suction, unusual motor noise, or frequent full-canister issues — these may signal system blockage or failure.

Why choose The Ductibles for this work

• We’re already set up for duct and vent services, so adding HRV or central VAC cleaning is a natural extension.
• We bring experience, high-quality equipment, and documentation of the work performed — so you know your system was properly maintained.
• As local Calgary specialists, we understand the airflow, dust, and indoor-climate conditions particular to the region. theductibles.com+1

Final words

Your home’s comfort and air quality rest on more than just the furnace or the vents you can see. Hidden systems like HRV units and central vac piping play a key role — and keeping them clean and functioning means a healthier, more efficient home. Want a quote or inspection?
