Air Duct Installation and Repair Service

Ductwork is the network of pipes that carries air between your furnace or air conditioner and the rooms of your home. Supply ducts deliver heated or cooled air to the registers, and return ducts bring air back to the system to be filtered and conditioned again. Well-designed, sealed ducts give every room even airflow and help keep indoor air clean.

Common signs include rooms that are always warmer or cooler than the rest of the house, weak airflow from some vents, rising energy bills, extra dust around registers, and whistling or rattling when the system runs. You may also see crushed, disconnected or damaged ducts in the basement or attic. If you notice any of these, book a ductwork consultation.

Uneven temperatures are often caused by the ductwork rather than the furnace or air conditioner. Leaky or disconnected ducts, undersized runs, long runs to rooms far from the equipment, closed dampers and missing return air can all starve a room of airflow. We measure airflow and inspect your ducts to find the cause before recommending a fix.

We take a pressure reading to measure how much air your duct system is losing, then inspect the ducts we can reach for gaps and loose joints. Depending on what we find, we seal the joints, repair damaged sections or replace ductwork that's beyond repair. You get a plain explanation of your options and an estimate before any work starts.

Yes. Undersized ducts restrict airflow, which can cause noisy registers, weak heating and cooling in some rooms and extra strain on your blower motor. Oversized ducts can leave air moving too slowly to reach the far end of the run. Properly sized ducts are planned around each room's heating and cooling needs and the equipment's airflow.

Whistling usually means air is being forced through a restriction, such as an undersized duct, a closed or blocked register, a dirty filter or a gap in a joint. Rattling often comes from loose duct sections, hangers or registers. Check your filter and make sure registers are open first. If the noise continues, we can find the cause and fix it.

Not always. Many homes can keep their existing ducts, but a new system may need modified or larger ducts if the old ones are undersized, leaky or damaged, or if the new equipment moves more air. We check your ductwork during the replacement quote and tell you honestly whether changes are needed.

Plan the ductwork before the walls and ceiling go up. A finished basement usually needs its own supply and return air so it stays comfortable, and existing ducts may need to be rerouted to fit the new layout. Keep access to dampers and joints where you can. In Hamilton, new or replacement ductwork needs a building permit, and we'll confirm what your project requires.

No. Duct sealing and repair fix leaks and damage so air reaches the rooms it's meant for. Duct cleaning removes dust and debris from inside the ducts to improve indoor air quality. They solve different problems, and some homes benefit from both: sealing for comfort and efficiency, cleaning for air quality.
