With scorching heat and humidity gripping Connecticut this summer, your air conditioner might be doing more harm than good—by silently spreading mold through your home.
At Mold Master Pro, we’re seeing a spike in calls from West Hartford, Manchester, and Windsor Locks where homeowners are reporting musty smells, worsened allergies, and mold buildup in AC vents and ductwork.
Why 2025 Is a Perfect Storm for HVAC Mold
Connecticut’s summer 2025 is on track to break records with back-to-back heatwaves and consistently high dew points. That means AC systems are running around the clock—and collecting condensation in ducts, coils, and filters.
Without proper drainage or maintenance, this moisture becomes a breeding ground for mold spores. As air circulates, mold spreads into bedrooms, living rooms, and even attics.
Warning Signs Your AC Might Be Spreading Mold
- Musty odors when the system turns on
- Visible black or green spots on vents
- Recurring allergy symptoms indoors
- Increased dust or moisture near vents
- Condensation on AC coils or air ducts
These signs often indicate hidden mold growth inside HVAC systems or connected spaces. Learn more in our Top 5 Signs Your Hartford County Home Needs Professional Mold Remediation.
Where Mold Hides Inside Your AC System
Even if your vents look clean, mold could be lurking deeper inside:
- Evaporator coils
- Condensate drip pans
- Blower fans
- Fiberglass duct liners
- Reusable AC filters
These areas are often warm, dark, and damp—ideal conditions for mold colonies to grow unchecked.
Is It Making You Sick?
Yes. Mold in your HVAC system can worsen indoor air quality dramatically. You may experience:
- Fatigue, headaches, or dizziness
- Worsening asthma or respiratory infections
- Itchy eyes, throat, or skin

How to Stop AC Mold Before It Spreads
Here are five things every Connecticut homeowner should do this summer:
- Change HVAC filters monthly—especially during heavy use
- Install a programmable thermostat to prevent overcooling
- Inspect and clean coils, pans, and ducts regularly
- Use dehumidifiers to keep indoor humidity below 60%
- Get a professional mold inspection if you suspect contamination
