Ductwork
Duct replacement in Tampa Bay
New, right-sized and well-insulated ducts when the old runs are too leaky, crushed or undersized to save.
The short answer
Duct replacement is the right call when the old runs are past sealing: cracked duct board, undersized branches, crushed flex, or insulation that has given out in a humid attic. FL HVAC Team designs and installs a new duct system sized to your equipment and your rooms, sealed and insulated for Florida attics, so your cooling actually reaches the house. Done right, new ducts fix uneven rooms, cut the power bill, and let a good system finally perform the way it should.
Sometimes sealing is not enough. Older Tampa homes often have deteriorated duct board, runs that were undersized from day one, or decades of rodent and moisture damage that no patch can fix. Mismatched ducts also choke a new, efficient air conditioner and rob it of the performance you paid for. We design the replacement around a proper load, size the runs to each room, and insulate and seal them for the attic they live in.
What we handle
Common ductwork jobs
Full system replacement
New supply and return runs when old duct board or flex is too deteriorated, leaky or moldy to keep.
Right-sizing undersized ducts
Many homes were built with ducts too small for comfort. We resize the runs so airflow and cooling reach every room.
Ducts for a new or bigger system
A new high-efficiency AC or heat pump needs matching ducts. We replace runs that would otherwise choke the equipment.
Additions and remodels
New runs and returns for added rooms, converted garages and remodels that the original system never covered.
How it works
Our process
Step 01
Assess and design
We inspect the current ducts, measure the home, and design a right-sized layout that fits your equipment and rooms.
Step 02
Remove and install
We remove the old runs, install new insulated ductwork, and seal every connection for a hot attic.
Step 03
Balance and verify
We balance the airflow room to room and confirm the whole house is cooling evenly before we finish.

Upfront about pricing
What affects the cost
Every job is quoted flat-rate before work starts. Here is what moves the number.
Scope of the replacement
Replacing a few runs costs less than a full redesign of the whole system. We scope exactly what needs to change.
Attic access and layout
Tight spaces, long runs and complex layouts add labor compared with an open, accessible attic.
Material and insulation level
The duct type and insulation rating you choose affect both the price and how well the system holds cooling in the heat.

Before you book
When should I replace my ducts instead of sealing them?
Replace when the ducts are badly deteriorated, crushed, undersized, or mold prone, or when they cannot keep up with a new system. If the runs are sound but leaky, sealing is usually enough. We give you both options.
How much does duct replacement cost?
It depends on the size of your home, the attic access and how much of the system you replace. We assess first and put a clear, written price in front of you before any work.
How long does a duct replacement take?
Many homes are completed in a day or two depending on the layout and access. We give you a realistic time estimate before we start.
Will new ducts lower my power bill?
Usually yes. Sealed, right-sized and well-insulated ducts stop wasting cooling in the attic, so the system runs less and your monthly cost drops.
Do I need new ducts with a new air conditioner?
Not always, but old or undersized ducts can choke a new efficient system and waste what you paid for. We inspect the ducts when we quote a new unit so you know before you buy.
Can new ducts fix rooms that never cool?
Often yes. Undersized or disconnected runs are a common cause of hot rooms. A right-sized, balanced design sends the airflow where it was missing.
Will replacement help with attic humidity and sweating?
Yes. New runs with proper insulation and sealed connections do not pull in humid attic air or condense the way worn-out ducts do, which improves comfort and protects your home.
Do you offer financing on duct replacement?
Financing is available for qualified buyers so a larger duct project fits a monthly budget.
