Cleaning, Repairs, Sealing and Modifications for Better Airflow
Your HVAC system can only deliver conditioned air as well as the ductwork allows. Mighty Air provides duct cleaning and ductwork services for residential and light commercial properties throughout Jacksonville and surrounding Northeast Florida communities.
Duct cleaning and ductwork repair solve different problems. Cleaning removes built up dust and debris from inside the ducts. Repairs, sealing and modifications fix ducts that are damaged, leaking or not moving enough air where it's needed. We inspect the system first, tell you which service fits what we find, and explain your options before any work begins.
Call Mighty Air, Inc. at (904) 292-0636 to schedule duct cleaning or a ductwork estimate in Jacksonville.Mighty Air uses professional Rotobrush duct cleaning equipment to help remove accumulated dust and debris from accessible ductwork when cleaning is appropriate. A rotating brush loosens debris inside the ducts while a vacuum pulls it out of the system.
Before any cleaning starts, our team checks the condition of the duct system and walks you through the cleaning process we recommend.

No single sign proves your ducts need cleaning. It's worth having them looked at if you notice:
Debris inside accessible ductwork or coming from supply vents.
Buildup that returns quickly after you wipe it away.
Smells that seem to come from the vents when the system runs.
Work near the duct system can leave drywall dust and debris inside it.
Some ducts are full of debris and cleaning makes a real difference. Others are clean, and the dust is coming from somewhere else. The inspection comes before the recommendation, every time.
BeforeAfterDamaged runs, leaky joints and undersized supply or return ducts need a repair or a modification. We find where the air is being lost and fix that.
Mighty Air does more than clean existing ductwork. When ducts are damaged, leaking or laid out in a way that limits airflow, we repair, seal, modify or replace them. Our ductwork services include:
When duct connections or sections leak, some of the conditioned air escapes into the attic or walls before it reaches your rooms. If we find leaks, duct sealing may help reduce that air leakage and improve how conditioned air is delivered through the system. Results depend on where the leaks are and the overall condition of the ductwork.
Some airflow problems stem from how the duct system was designed or installed, and no amount of cleaning or sealing will fix them. A room that never gets enough air may need a larger or added supply run. A system that struggles to pull air back may need a larger or added return.
We measure and diagnose the airflow first, then explain what change would correct it and why.
Damaged ductwork repair
New supply and return installationDamaged or disconnected sections can often be repaired. Replacement may make more sense when the duct system itself has become the problem, especially in older homes.
Signs it may be time to replace
Ductwork that leaks or restricts airflow also makes your HVAC equipment work harder to keep up. We'll look at the whole duct system and tell you whether repair or replacement is more practical. If you're replacing your equipment, we also check whether the ductwork needs changes to work with the new system. Learn more about AC Installation & Replacement.
Uneven temperatures can result from duct restrictions, improper supply or return airflow, damaged ductwork, insulation problems or other HVAC conditions. Sun exposure, room layout and thermostat location can also play a part.
Mighty Air evaluates the airflow and the existing system before recommending modifications or repairs. When the ductwork is part of the cause, the fix may be sealing, a repair, or a supply or return modification. Some temperature differences have other causes, and if that's what we find, we'll tell you.


Duct cleaning is only one part of addressing indoor air quality concerns. Filtration, humidity, ventilation and the condition of the HVAC system all affect the air in your home. If your main concern is dust, odors or humidity, our Indoor Air Quality Services look at the whole system instead of assuming clean ducts will solve it.
Indoor Air Quality Services
Mighty Air provides duct cleaning and ductwork services for homes and light commercial properties. Qualifying light commercial HVAC installations, including rooftop and packaged equipment, sometimes need duct modifications so the new system can move air correctly.
Commercial HVAC ServicesOur name is on every van and every invoice. That's why we inspect the ducts before recommending anything, and quote the work the system actually needs.

Quick answers to the questions Jacksonville homeowners ask us most about duct cleaning and ductwork.

Cleaning removes dust and debris from inside the ducts. Repair, sealing and modifications fix ducts that are damaged, leaking or not delivering enough air. Many airflow problems need ductwork repair, not cleaning.
Damaged, disconnected or restricted ducts can cause it, but so can a dirty filter, a blower problem or an indoor coil issue. If airflow is weak in every room, the cause is often different than when only one or two rooms are affected. We diagnose the system to find where the problem starts.
Often, yes. When the duct layout is the cause, a supply or return modification can correct the airflow. We evaluate the system first, since insulation, sun exposure and other factors can also cause uneven temperatures.
It can. When cooled air escapes before reaching your rooms, the system may run longer to reach the set temperature. Equipment condition, insulation and other factors affect run time too, so we look at the whole system.
It depends on the extent, location, age and condition of the ducts. Isolated damage is often repairable. Widespread deterioration or a layout that doesn't fit the system may make replacement more practical.
Yes. Mighty Air provides ductwork services for residential and light commercial properties, including duct modifications for rooftop and packaged equipment.
Whether your ducts need cleaning, a repair or a change to fix airflow, Mighty Air will inspect the system and tell you what it needs before any work begins.
