Your Local Air Duct Experts — Cleaning, Repairs & Sealing
From cleaning, to repairs and duct sealing, Alberta Indoor Comfort is your local air duct expert. We're one of the few Calgary companies certified to offer Aeroseal duct sealing — an innovative method that finds every crack and crevice in your air ducts and seals it shut from the inside, preventing air loss without opening a single wall. This non-toxic application can eliminate up to 30% of air duct loss, and it's safe and easy to apply, usually in less than a day.
Have You Cleaned Your Air Ducts Lately?
If the answer is no, you and your family could be breathing contaminated indoor air on a daily basis. Regular air duct cleaning is as important as replacing your HVAC filter — if your air ducts are dusty and dirty, the air being circulated by your HVAC system will be just as full of airborne contaminants. This can mean a higher energy bill, and it can affect your health: breathing polluted indoor air has been linked to common respiratory diseases, asthma, and allergies, and people with impaired immune systems are particularly sensitive to it.
Call Alberta Indoor Comfort for a thorough air duct cleaning that will have you breathing a sigh of relief — you'll notice the difference in how you feel when the air in your home is clean and safe to breathe.
Not Sure If You Need Cleaning or Sealing?
Book a free duct inspection — a licensed Calgary technician measures your actual duct leakage and shows you the data before recommending anything.
Why You Should Be Concerned About Duct Losses
Duct loss is the term for air that blows through the ducts of your HVAC system leaking out through cracks and crevices before it reaches your living space. That's not only a waste of conditioned air — it's a significant cause of energy inefficiency.
Just as conditioned air escapes through damaged ducts, dust, debris, and other allergens make their way in and get distributed throughout your home. Left unresolved, duct loss doesn't just raise your energy costs — sometimes by half — it also poses a real threat to your health and your family's.
Call Alberta Indoor Comfort for an honest evaluation of your air ducts. A licensed technician can determine whether you're experiencing duct loss and how to prevent it, then present you with options to resolve it.

Match Your Problem to the Right Service
Dusty Air or Allergy Symptoms
Dust, dander, and mold spores circulating from contaminated ducts — addressed by professional duct cleaning with Benefect disinfection. Recommended every 3–5 years, or annually for households with pets or allergy sufferers.
Uneven Temperatures or High Bills
30–50% of conditioned air can escape through duct leaks before reaching its destination — resulting in hot/cold spots and HVAC systems that run longer than they should. Addressed by Aeroseal duct sealing.
Musty Odours from Vents
Musty or stale odours from registers indicate biological contamination (mold, bacteria) in the duct system. Duct cleaning combined with Benefect disinfection removes both the debris and the contamination at the source.
Post-Renovation Air Quality
Construction releases drywall dust, fiberglass insulation fibres, and VOCs into the duct system. Post-reno duct cleaning removes construction contamination that standard filters can't capture — critical before extended occupancy.
Why Aeroseal Duct Sealing Is the Way to Go
When dirt and dust enter your air vent system, it follows that not all of the conditioned air from your system is making it to your living spaces — just as dust seeps into your air ducts through cracks, conditioned air seeps out of those same cracks. Aerosealing your air ducts is the solution: it's been reported by the U.S. Department of Energy as a proven, effective sealing technology that can eliminate up to 30% of air duct loss. Aerosealing isn't new — it's been used for more than twenty years to improve air quality in homes and commercial buildings like hospitals, hotels, and schools.
Aerosealing is also safe for our planet. It's recommended by both the U.S. Department of Energy and the Environmental Protection Agency (EPA) — whose research found indoor air can be up to one hundred times more polluted than outdoor air. Their studies confirm the techniques and materials used in aerosealing are safe to apply without harming the environment. It's a simple yet powerful application that finds every nook and cranny in your air ducts and seals them shut — non-toxic, safe, and done in less than a day.

Air Duct Service Questions
Should I clean or seal my ducts first?
If your ducts have significant contamination, cleaning first is typically recommended. Heavy debris can interfere with Aeroseal particle travel during sealing. In most cases, we assess the duct condition at the consultation and recommend the appropriate sequence — many homes can go straight to sealing without a prior clean.
How do I know if my ducts need cleaning vs. sealing?
If your primary complaint is air quality, allergy symptoms, or dusty air — cleaning is the starting point. If your primary complaint is uneven temperatures, cold rooms, high energy bills, or visible gaps in accessible ductwork — sealing is the priority. Many homes benefit from both. We measure duct leakage at the consultation and show you the data before recommending anything.
Can ductwork be repaired rather than replaced?
Yes, in most cases. Disconnected joints, crushed flexible duct, and gaps at register collars can all be repaired without replacing the entire duct system. Aeroseal seals gaps from the inside that are too small or inaccessible for manual repair. We recommend replacement only when ductwork is structurally compromised, severely undersized, or showing extensive deterioration.
