Condo Fan Coil Mold in Toronto: Causes, Risks, and What To Do
Mold inside a condo fan coil is one of the most common — and most dangerous — hidden HVAC problems in Toronto condominiums. Every week, Hudson technicians discover mold growing inside fan coil units, drain pans, coils, insulation, and ductwork.
If you are searching for condo mold in Toronto, fan coil mold, or HVAC mold remediation, this guide will explain what causes it, why it is dangerous, and how it should be properly removed.

Why Mold Grows Inside Condo Fan Coils
Fan coils create the perfect environment for mold:
- Warm air
- Moisture from cooling
- Condensation
- Dust and organic debris
- Dark, enclosed spaces
In Toronto’s humid summers, every air conditioner produces condensation. If that water does not drain properly, it stays inside the unit and feeds mold growth.
Common mold sources include:
- Rusted drain pans
- Clogged drains
- Wet insulation
- Corroded coils
- Leaking valves
- High humidity
These problems are extremely common in condo HVAC systems.

How Mold Spreads Through Your Condo
A fan coil is not just a machine — it is the air distributor for your entire suite. When mold grows inside the unit, it is blown into:
- Bedrooms
- Living rooms
- Bathrooms
- Closets
- Hallways
You may not see mold on the walls, but it is circulating in the air every time your AC or heating runs.
Health Risks of Fan Coil Mold
Condo HVAC mold can cause:
- Chronic coughing
- Sinus infections
- Headaches
- Fatigue
- Asthma flare-ups
- Skin irritation
- Eye irritation
Many residents think they have allergies or a cold — when the real cause is mold inside their fan coil.
This is especially dangerous for:
- Children
- Seniors
- Anyone with asthma
- Anyone with weakened immunity
Warning Signs of Mold in Your Fan Coil
You should have your HVAC system inspected if you notice:
- Musty or damp smells when the air runs
- Black dust coming from vents
- Visible mold inside the cabinet
- Water or rust in the drain pan
- Increased allergy symptoms
- Worsening air quality

Mold Is Usually a Symptom of Bigger HVAC Problems
Mold rarely appears on its own. It is usually caused by:
- Failed actuators keeping chilled water flowing
- Leaking valves
- Blocked drains
- Corroded drain pans
- High humidity inside the cabinet
These mechanical problems must be fixed or the mold will come back.

Why Wiping Mold Is Not Enough
Many residents try to clean visible mold themselves. This does not work.
Mold hides:
- Inside insulation
- Under coils
- In drain pans
- In duct connections
If the unit is not disassembled and professionally cleaned, mold will regrow within weeks.
This is why Hudson performs full HVAC mold remediation, not surface wiping.

Why Toronto Condos Have Higher Mold Risk
Toronto condos are especially vulnerable because:
- Buildings run chilled water for long periods
- Suites have sealed windows
- High indoor humidity is common
- Drain systems are aging
- Fan coils are rarely cleaned
Without professional maintenance, mold growth is almost guaranteed.
