Ductwork & airflow

Rooms that never cool down are often an airflow problem. We check ducts, filters, and returns.

Know the signs

Airflow problems look like this

A new AC can’t fix a duct problem. If some rooms are always hot while others are cold, the air may not be getting there.

We look at the whole path the air takes, from the return grille through the system and out to every supply vent.

  • One or two rooms are always hotter or colder than the rest
  • Weak airflow from some vents
  • Whistling vents or doors that slam when the system kicks on
  • Dust building up quickly after cleaning
  • Upstairs stays hot all summer
The work

What we check and fix

Leaks & disconnects

Torn or disconnected duct runs in the attic that blow cooled air into the heat.

Returns

Too little return air starves the system. We check return size and add returns where needed.

Filters & grilles

The wrong filter or a blocked grille can choke airflow on a healthy system.

Duct sizing & repair

Crushed, undersized or poorly routed runs repaired or replaced.

From real jobs

When the duct seal fails

Ducts don’t only leak in the attic. Here is a connection we found on a rooftop unit.

Cracked and peeling sealant where an insulated duct joins a rooftop unit

Cracked sealant at the duct connection

Where the supply and return duct meets the unit, the sealant and roof coating have cracked and are peeling away. Gaps like this leak cooled air outside and let rain into the duct and the building.

How we fix itWe strip the loose coating, seal the seams with mastic and foil tape, recoat it to stand up to the weather, check for water damage inside, and measure airflow when we’re done.

Questions we hear

FAQ

Will fixing ducts lower my bill?

Leaky ducts in a hot attic waste cooling you already paid for. Sealing and repairing them usually helps comfort first, and often the bill too. We show you what we find before recommending work.
