Ductwork
Duct repair and sealing in Tampa Bay
Find and seal the hidden leaks that let your cooling vanish into a hot attic, so rooms cool evenly and your power bill drops.
The short answer
Duct repair and sealing is the highest-value fix most Tampa homeowners never think about. FL HVAC Team inspects your runs, finds the leaky joints, loose connections and gaps in the insulation, then seals them with mastic and proper materials so your cooling reaches the rooms instead of the attic. The result is rooms that finally match the thermostat, a system that stops running nonstop, and a noticeably lower summer bill.
A typical duct system loses a meaningful share of its air to leaks, and in Florida those leaks sit in an attic that bakes past 130 degrees. Every gap dumps cold air into the heat and draws hot, humid air back toward your rooms. We seal the connections at the plenum, boots and branch takeoffs, reconnect runs that have pulled apart, and repair or replace failed insulation so the ducts hold the cooling you are paying for.
What we handle
Common ductwork jobs
Leak sealing at joints and boots
We seal the plenum, branch connections and register boots with mastic where most of the air loss happens.
Reconnecting and supporting runs
Flex runs that sag, kink or pull loose choke airflow and leak. We reconnect, straighten and support them properly.
Insulation repair
Torn or thin duct insulation sweats and wastes cooling. We repair or upgrade it so the ducts stop condensing in humid attics.
Rodent and age damage fixes
Older Tampa homes often have chewed or crushed sections. We patch or replace the damaged runs to restore the system.
How it works
Our process
Step 01
Inspect and test
We walk the duct system, locate leaks, crushed runs and failing insulation, and show you what is costing you cooling.
Step 02
Seal and repair
We seal connections with mastic, reconnect loose runs, and repair or replace damaged insulation and sections.
Step 03
Verify airflow
We check that rooms are getting the airflow they should and confirm the fixes before we leave.

Upfront about pricing
What affects the cost
Every job is quoted flat-rate before work starts. Here is what moves the number.
Number and location of leaks
A few accessible joints are a quick seal. Widespread leaks or hard-to-reach runs take more labor, which we quote up front.
Attic access and layout
Tight crawl spaces and long, complex runs take longer to seal than an open, walkable attic.
Condition of the insulation
Ducts with intact insulation need only sealing, while torn or missing insulation adds repair or replacement to the job.

Before you book
How do I know my ducts are leaking?
Rooms that never cool, high power bills, a system that runs nonstop, and dusty registers are all signs. We inspect the runs to confirm where the air is being lost.
How much does duct sealing cost?
It depends on how many leaks there are and how accessible the ducts are. We inspect first and give you a clear, written price before any sealing begins.
Is duct sealing worth it in Florida?
Very often yes. Because Tampa ducts run through a scorching attic, sealing the leaks stops you cooling that attic and usually pays back through lower bills and more even rooms.
Will sealing my ducts lower my power bill?
Typically yes. Keeping your cooled air inside the ducts means the system reaches the set temperature faster and runs less, which lowers your monthly cost.
What do you seal the ducts with?
We use mastic and proper materials at the joints and connections, which hold up in a hot attic far better than standard tape that dries out and peels.
Can you fix ducts chewed by rodents?
Yes. Older Tampa homes often have chewed or crushed sections. We patch or replace the damaged runs and seal the connections to restore the system.
Why are my ducts sweating?
Ducts sweat when humid attic air hits a cold surface through torn or thin insulation. We repair or upgrade the insulation so they stop condensing and dripping.
Will sealing help with uneven room temperatures?
Usually. Many uneven rooms are caused by a leaking or disconnected branch starving that run. Sealing and reconnecting it sends the airflow back where it belongs.
