Ductwork Repair & Sealing in Sarasota, FL

Signs of duct problems

Rooms that never cool, weak airflow from some vents, dust, high power bills, musty smells, and condensation or stains on ceilings near vents.

Leaks and disconnections

Ducts can come apart at joints, get crushed or torn, or have tape that has failed in the heat. Sealing with mastic or approved tape and repairing damaged sections restores airflow.

Condensation

Cold ducts in a hot, humid attic can sweat if insulation is missing or damaged. Dripping water stains ceilings and can lead to mould.

Balancing airflow

Rooms far from the air handler, or with lots of west-facing glass, may need larger ducts or adjusted dampers.

Return air

Too few or too small return vents starve the system of air. Adding returns can improve comfort and efficiency.

Duct cleaning

Cleaning can help after renovations, pest problems or visible mould. It isn't a fix for leaks or poor design.

With a new system

Replacing an AC is a good time to test and repair ducts so the new equipment works as rated. See AC replacement.

Duct testing

A duct leakage test pressurises the system and measures how much air escapes. It shows whether sealing will help and gives a baseline to compare against after repairs.

Insulation

Ducts in an attic should be wrapped in insulation in good condition. Torn or missing insulation lets the duct sweat and heat up the cooled air before it reaches the room.

Frequently asked questions

How much air do leaky ducts lose?
It varies widely. Testing shows how much air is escaping and where.
Can ducts cause humidity problems?
Yes. Leaky return ducts in a hot attic pull humid air straight into the system.
