Air Duct Repair Baltimore, MD

Professional Air Duct Repair Services in Baltimore, MD

Uneven airflow from room to room is often a sign of leaking or damaged air ducts. Baltimore Air Duct Cleaning Pro repairs leaking and damaged air ducts so air reaches every room. A pressure test comes first, so we know how much air the ducts are losing and where. We straighten crushed or kinked sections so air can move freely again. Each repair is checked for a tight seal before we move to the next one. After the work, we inspect every repaired section and show you the results. Below are the specific air duct repair services we offer for residential and commercial properties.

Air Conditioning Duct Repair in Baltimore

When an AC system cools some rooms and leaves others warm, the cause often sits in a damaged supply branch between the air handler and the weak room. Our technician measures airflow at each register, then follows the branch serving the weak room through the attic with a camera and flashlight. Common finds include a kinked flex run, a split inner liner, or a branch that slipped off its takeoff. We replace the damaged length with new insulated duct, fasten each end with a tie band, and seal the connections with mastic. The branch gets strapped at close intervals so it cannot sag again. The weak room reaches its set temperature along with the rest of the house.

Air Duct Leak Repair in Baltimore

Duct leaks form at seams, joints, and takeoffs when cloth tape dries out and metal edges pull apart. Our air duct cleaning services team pressurizes the duct system with a calibrated duct leakage tester and uses a smoke pencil to locate each leak. We clean dust and old tape from every leaking seam and brush on a thick coat of water-based mastic, embedding fiberglass mesh tape across wider gaps. Loose takeoffs and collars get screwed back in place before sealing. A final pressure test measures the drop in leakage so you see the result in numbers. Your system delivers more cooled air to each room, and less attic dust enters through the return.

Air Duct Cleaning and Repair in Baltimore

Damaged ducts often hold the most dust, because leaks on the return side pull in attic insulation and debris through every gap. Baltimore Air Duct Cleaning Pro inspects the full system with a camera and marks both the dirty sections and the damaged ones before starting. We clean the ducts first, placing the system under negative pressure with a HEPA vacuum and running rotary brushes through each branch. Once the ducts are clean, the crew repairs torn flex, reconnects loose joints, and seals each seam with mastic. Handling both jobs in one visit keeps new debris from entering a freshly cleaned system. You get clean air from every vent through ductwork that no longer leaks.

Flex Duct Repair in Baltimore

Flexible duct sags between hangers, kinks at tight bends, and tears when someone steps on it in the attic, and each of those problems chokes airflow. Our technician walks each flex run in the attic, noting sags, crushed sections, and rips in the outer vapor jacket. Torn inner cores get cut out and replaced with a new section joined by a sheet metal coupling, tie bands, and mastic. When damage is too extensive for a patch, we recommend air duct replacement for the full run. We re-hang sagging runs with wide straps and pull each run straight to remove excess length. Tears in the outer jacket get sealed with UL 181 foil tape to keep humid attic air off the inner core. Air moves through each flex run at full strength, and condensation on the duct jacket stops.

Disconnected Duct Repair in Baltimore

Ducts pull loose at the plenum, takeoff, or register boot when old tape fails in attic heat or when a worker bumps a run during other attic work. Our air duct installation team checks each room for weak or missing airflow and traces the matching branch back to find the separated joint. We clean both ends, slide the duct back over its collar, and secure the inner core with a tie band. Rigid metal joints get fastened with sheet metal screws before sealing. Every reconnected joint gets a coat of mastic, and the outer jacket gets pulled over and strapped. Air returns to the room right away, and your AC stops cooling the attic.

Duct Insulation Repair in Baltimore

Duct insulation compresses, tears, and falls away over time, and bare duct in a hot attic both loses cooling and forms condensation. Our technician inspects the ductwork for exposed metal, wet insulation, and water stains on the ceiling below. We remove soaked or moldy insulation and let the duct surface dry before rewrapping. New foil-faced duct wrap goes on with overlapping seams taped with UL 181 foil tape so the vapor barrier stays continuous. Rigid trunk lines get fitted with insulation rated for attic temperatures. Every repaired section gets checked with a thermal camera to confirm no bare spots remain. The ducts stop sweating onto the ceiling, and air leaves each vent colder.

Sheet Metal Duct Repair in Baltimore

Sheet metal trunks and plenums develop leaks where seams split, screws back out, or rust eats through the metal in damp areas. Baltimore Air Duct Cleaning Pro inspects rigid trunks, elbows, and transitions for open seams, rust holes, and loose hangers. We patch small holes with sheet metal plates fastened by screws and sealed with mastic. Badly rusted sections get cut out and replaced with new galvanized fittings fabricated to match the existing duct size. Loose trunks get re-hung on proper supports so their joints stay tight. Each repaired seam gets a pressure check before the technician moves to the next section. The trunk line carries air to every branch without whistling or leaking at the seams.

Supply and Return Plenum Repair in Baltimore

The plenums attach directly to the air handler, so vibration and high air pressure at those connections loosen seams faster than anywhere else in the system. Our home ventilation cleaning team inspects the supply plenum, the return plenum, and the flange joints at the air handler cabinet. We tighten or replace loose fasteners, reseal the flanges with mastic, and replace duct board plenums that have crumbled or delaminated. Return plenums in closet platforms get sealed at every framing joint so the system stops pulling air from wall cavities. A static pressure reading confirms the air handler works within its rated range after the repair. The system runs quieter, and airflow increases at every vent in the house.
