Spring Guide to HVAC Filter Changes & Duct Cleaning in Ottawa

 
HVAC system with filters and ducts

Maintaining your home’s HVAC system is one of the most effective ways to improve indoor air quality, reduce energy bills, and ensure long-lasting comfort—especially in a climate like Ottawa’s, where systems work overtime in both winter and summer. Spring is the ideal time to give your HVAC system a fresh start, focusing on two key areas: filter changes and duct cleaning.

This guide explains what to do, when to do it, and whether duct cleaning is worth it for your home.

I. Understanding HVAC and Indoor Air Quality

 
Your HVAC system affects far more than temperature — it impacts your comfort, health, and energy savings. When filters clog or ducts become contaminated, your system works harder, costs more to run, and circulates debris back into your living space.
 

The History Behind Air Filtration


Air purification has evolved dramatically:
 
  • Ancient civilizations used charcoal and smoke-filtration concepts.
     
  • The Roman hypocaust system was an early form of controlled indoor heating.
     
  • WWII’s Manhattan Project led to major advancements in filtration for radioactive particulates.
     
  • The 1960s–70s gave rise to the household filters we use today.

II. DIY Air Filter Changes Why Filter Changes Matter

 

  • Health: Reduces allergens, dust, pet dander, and respiratory strain.
     
  • Savings: Can lower energy use by 5–15%.
     
  • Longevity: Prevents strain that shortens HVAC lifespan.
     
How Often Should You Change Filters?
 
Every 30–90 days, depending on:
 
  • Pets in the home
     
  • Allergies or asthma
     
  • Recent renovations
     
  • Heavy heater or AC usage (typical in Ottawa)
     
Light Test: Hold the filter up to a light source.

If light barely passes through, replace it.
 
How to Replace Your HVAC Filter
 
1. Turn off the HVAC system.

2. Locate the filter slot (furnace or air handler).

3. Remove old filter and note the airflow arrow direction.

4. Insert a new filter with the correct arrow orientation.

5. Vacuum around the slot.

6. Turn the system back on.
 
Choosing the Right Filter
 
  • Fiberglass: Budget, minimal filtration
     
  • Pleated: Good balance of price & filtration
     
  • HEPA: Highest filtration (often requires compatible systems)
     
  • MERV Rating: Stick to MERV 8–13 for best airflow + filtration

III. The Duct Cleaning Debate

 

Duct cleaning is one of the most misunderstood HVAC topics.
 
Why Some Experts Recommend It
 
Supporters argue ducts can harbor:
 
  • Dust and allergens
     
  • Mold growth
     
  • Pest debris
     
  • Post-renovation particles
     
These can circulate through your home and impact air quality.
 
Why Others Disagree
 
Organizations like Consumer Reports and even the EPA note limited proof that routine duct cleaning improves health or efficiency unless specific issues exist.
 
When Duct Cleaning Is Recommended
 
  • Visible mold inside ductwork
     
  • Persistent musty odors
     
  • Evidence of rodents or insects
     
  • Excess dust blowing from vents
     
  • Recent construction or drywall work
     
  • Unexplained increases in energy bills
     
DIY Duct Cleaning?
 
Not recommended.
Household vacuums lack the power and can loosen debris without removing it.
