Signs You Need Duct Cleaning or Replacement

Musty or moldy smell when the AC runs — mold in the ductwork
Visible dust or debris blowing from vents
Uneven cooling — some rooms hotter than others
Increased energy bills — leaky or blocked ducts waste 20-30% of conditioned air
Allergy symptoms worsen indoors — trapped pollen, pet dander, dust mites
Pest evidence — droppings, nesting materials, or dead insects in vents
Ducts over 15 years old — duct material degrades, joints loosen, insulation fails
Recent renovation — construction dust and debris inside duct system

Duct Cleaning vs. Duct Replacement

Duct Cleaning

Best for: Ducts in good condition with dust, allergen, or mold buildup.

Process: High-powered vacuum + rotary brush system cleans every vent, return, and trunk line.

Cost: $300–$700 for a typical Florida home.

Frequency: Every 3-5 years in Florida (humidity accelerates buildup).

Duct Replacement

Best for: Damaged, disconnected, or aging ductwork (15+ years). Ducts with major mold or pest contamination.

Process: Remove old ducts, install new insulated flexible or rigid ductwork, seal all connections.

Cost: $2,000–$6,000 depending on home size and duct type.

Lifespan: New ducts last 15-25 years with proper maintenance.

Why Duct Service Matters More in Florida

Florida's climate creates unique challenges for ductwork that homeowners in drier states don't face:

Year-round humidity causes condensation inside ducts → mold growth
Attic temperatures exceeding 150°F degrade duct insulation and tape faster
AC runs 8-10 months per year → more wear on duct joints and connections
Hurricane damage can disconnect or crush ductwork in attics
Pest intrusion — rodents and insects enter through gaps in attic ductwork

The EPA estimates that leaky ducts waste 20-30% of conditioned air. In Florida, where AC accounts for 40-60% of your electric bill, that's hundreds of dollars per year wasted. Professional duct sealing and cleaning pays for itself.

Duct Cleaning & Replacement — Frequently Asked Questions

How much does duct cleaning cost in Florida?

Professional duct cleaning in Florida typically costs $300–$700 for a standard home (2,000-3,000 sq ft). Larger homes or systems with severe contamination may cost more. Beware of $99 whole-house specials — they usually clean only the main trunk line, not individual runs.

How often should I clean my ducts in Florida?

In Florida, we recommend duct cleaning every 3-5 years due to our high humidity and year-round AC usage. If you have pets, allergies, or notice musty odors, clean more frequently. After any renovation, clean ducts immediately.

How much does duct replacement cost in Florida?

Complete ductwork replacement costs $2,000–$6,000 for a typical Florida home. The price depends on home size, duct material (flex vs. rigid), accessibility, and whether you're also replacing the air handler. Financing is available.

Can dirty ducts make you sick?

Yes. Dirty ducts can circulate mold spores, dust mites, bacteria, and allergens throughout your home. Florida's humidity makes mold growth in ducts especially common. If family members have unexplained allergies, asthma flare-ups, or respiratory issues that improve when away from home, dirty ducts may be the cause.

What is HVAC duct sealant and do I need it?

HVAC duct sealant (mastic or Aeroseal) seals leaks at duct joints and connections. Most Florida homes lose 20-30% of conditioned air through duct leaks. Sealing is less expensive than replacement ($500–$1,500) and can reduce your energy bills by 15-20%.
