Compare Airflow Between Rooms at the Same Time

Uneven cooling between rooms — especially rooms far from the air handler — is one of the clearest signs of duct leakage or poor design, rather than an AC unit problem itself.

Feel airflow at vents in different rooms at the same time of day.
Rooms with consistently weaker airflow often sit at the end of a leaking duct run.
A 15%+ difference in comfort between rooms usually points to ductwork, not the AC unit.

Why Houston Ductwork Fails Faster

What Makes Houston Attics Hard on Ducts

ATTIC HEAT

Extreme attic temperatures

Houston attics regularly exceed 130°F, stressing duct materials and seals.

HUMIDITY

Condensation issues

Poorly insulated ducts can sweat in humid conditions, promoting mold.

AGE

Aging duct connections

Older homes often have deteriorated duct tape and disconnected joints.

PESTS

Rodent & pest damage

Attic pests are a surprisingly common cause of duct punctures.

Questions

Frequently Asked Questions

How do I know if my ducts are leaking?

Uneven cooling between rooms, higher-than-expected bills, and dusty rooms are all common signs.

Is duct sealing worth the cost?

Leaky ducts can waste 20-30% of conditioned air — sealing often pays for itself in energy savings.

Do you clean ducts, not just seal them?

Yes, we offer both cleaning and sealing, either separately or as a complete service.

How long does duct sealing take?

Most residential duct sealing is completed in a single day.

Will duct repair lower my energy bills?

In most cases yes, since less conditioned air is lost to leaks before reaching your rooms.
