Duct design & sizing
Trunk and branch layout sized to the design airflow, not fitted to the space left over.
Ductwork & Lineset Services
Duct and refrigerant-line design, sealing, and balancing to real airflow targets, so no room is starved and no energy is paid for twice.

Ductwork & Lineset · AirPrime
Overview
Most comfort complaints that reach a property manager are airflow problems, not equipment problems. Rooms that never balance, hot floors, and high bills usually trace back to undersized, leaky, or badly routed ductwork and refrigerant lines.
We size, install, modify, and seal ductwork and linesets to the design airflow, with pressure-tested refrigerant lines and proper insulation. The result is a system that delivers the capacity it was sized for, to every room.
What we deliver
Scope of the service
Sealing & insulation
Sealed joints and insulated runs, so conditioned air reaches the room instead of the cavity.
Lineset install
Correctly sized and routed refrigerant lines, brazed, insulated, and pressure-tested.
Airflow balancing
Measured and balanced, so each zone gets the airflow it was designed for.
Retrofit & repair
Modification and repair of existing duct and lineset without tearing up the whole building.
Designed by calculation, documented for sign-off.
Size
Sized to airflow
Ducts and lines are sized from the load and the airflow targets, not from what fits the chase.
Seal
Sealed and insulated
Sealing and insulation are done properly, so you are not paying to condition the framing.
Balance
Balanced and verified
Airflow is measured room by room and balanced, so the design capacity actually lands.
Common questions
Do you size ducts to airflow or to the space left over?
To the design airflow. Trunk and branch layout is sized from the load, not fitted to the chase.
Do you seal and insulate the runs?
Yes. Sealed joints and insulated runs, so conditioned air reaches the room instead of the cavity.
Can you modify existing ductwork without tearing up the building?
Yes. We retrofit and repair existing duct and lineset with minimal disruption.
