AC Repair Services › Ductwork Inspection and Sealing

Ductwork Inspection and Sealing in Plano, TX

Ductwork is the delivery system for everything your AC produces. When sections pull apart or develop gaps, conditioned air bleeds into the attic instead of reaching the rooms. In older Plano homes, this is common and often undiagnosed — the AC runs fine but the house never cools evenly because the air isn't going where it's supposed to.

When to Call

When You Need Ductwork Inspection and Sealing

Some rooms in the house are always warmer than others regardless of the setting.
Your energy bills increased significantly but the AC hasn't changed.
You can feel weak airflow from certain vents even when the system runs hard.
The attic gets extremely hot and you've never had the ductwork inspected.
You have a home built before 2000 and ductwork has never been evaluated.
After foundation repair work, your airflow pattern changed noticeably.

How It Works

Our Process for Ductwork Inspection and Sealing

1

Airflow assessment at registers

We check airflow at each supply and return register to map which rooms are receiving adequate air and which are noticeably short. This gives us a target before we enter the attic.
2

Attic inspection of duct runs

A technician walks the accessible attic sections and physically checks each duct run, connection, and flex duct segment for gaps, disconnections, and collapsed sections.
3

Document problem areas

We photograph or note every location where the ductwork has separated, where insulation has degraded, or where a section has pulled away from a boot or plenum.
4

Written scope of repair

We provide a written list of what needs to be sealed, reconnected, or replaced before any work begins. You know exactly what we're doing in the attic.
5

Sealing and reconnection

Gaps at joints get mastic sealant or metal tape. Disconnected flex duct sections are reconnected and secured properly, not just pushed back together and taped with household tape.
6

Recheck airflow

After sealing, we verify that the rooms that were short on airflow have improved. This confirms the leaks we sealed were the actual cause of the problem.

What's included

Visual inspection of accessible attic duct runs and connections.
Airflow check at registers before and after sealing work.
Sealing of gaps and joints with mastic or appropriate metal tape.
Reconnection of any sections that have pulled away from boots or plenums.
Written documentation of what was found and what was repaired.

What's not included

Full duct replacement if sections are too degraded to seal — that is a separate scope and cost.
Crawlspace ductwork is a different access situation and quoted separately if applicable.
Duct balancing for new construction or major remodels is outside this scope.

Real Situations

Common Scenarios in Plano

A homeowner in a 1994-built Plano home has one bedroom that's always 8 degrees warmer than the rest of the house.

We check that room's supply duct run from the plenum to the register. In homes that age, flex duct often pulls apart at the connection point near the plenum due to attic heat cycling. We reconnect and seal it, which usually solves the imbalance immediately.

A homeowner notices their energy bills have crept up over three years even though they've kept up with filter changes.

We inspect the duct system because gradual bill increases with no equipment change often point to duct degradation. Slow separation at joints bleeds conditioned air into the attic, making the AC work harder without delivering more cooling to the living space.

After a foundation leveling job on a home near Plano's older Preston Road corridor, the homeowner notices the airflow pattern in the house has shifted.

Foundation work moves the house. That movement can pull flex duct connections loose or shift rigid duct boots away from registers. We inspect the full system after that kind of work to find anything that shifted.

Plano Context

Why this matters in Plano

Plano has a large stock of homes built between 1985 and 2000, and most of them have flex duct systems that have never been inspected. The attic temperatures here regularly exceed 140 degrees in summer, which degrades duct insulation and causes flex duct to stiffen and pull apart at joints. The clay soil movement that causes foundation shifting in this area also stresses duct connections over time.

Straight Talk

About pricing & scope

The scope of duct sealing depends entirely on what we find in the attic. A few loose connections is a straightforward job. Widespread flex duct degradation across multiple runs takes more time and may require partial duct replacement rather than just sealing. We document what we find before quoting the repair so you know what you're looking at.
