Is Your Ductwork Working Against You?
Leaky ducts pull hot, humid attic air into your home every time the AC runs. These are the signs most San Antonio homeowners overlook for years.

Let Goettl Take Care Of It
We don’t just vacuum your ducts and move on. We find out why they’re dirty and then we fix it.
Duct Cleaning
We clean every supply and return line in your San Antonio home and document what we find. If your ducts are excessively dirty, there’s usually a leak problem behind it.
Duct Sealing
Duct tape fails in San Antonio attic heat and humidity. We use a permanent liquid sealant that bonds from the inside so the repair lasts for good.
Duct Replacement
Aging or undersized ductwork can’t keep up no matter how good your system is. We calculate the right size, replace the system, and balance airflow room by room.

Attic Insulation
Sealing ducts without insulating is only half the fix. We pair duct work with proper insulation so South Texas heat and humidity stay out and your system runs as efficiently as possible.

We Fix the Ducts.
And the Reason They Failed.
Good duct systems don’t get excessively dirty. If yours does, something else is wrong. We find it.
We run a camera before we touch anything.
We inspect your ductwork with a camera so you see exactly what’s inside. Leaks, damage, buildup, and blockages are all documented before any work begins

We use liquid sealant, not tape that fails.
Standard duct tape fails in San Antonio’s temperature extremes. We use a permanent liquid sealant that bonds to the duct from the inside, so the repair actually lasts.

We make sure every room gets the right airflow.
After cleaning and sealing, we balance airflow room by room so every space in your home gets the comfort it needs. No more hot spots, no more fighting over the thermostat.

We look at your whole system, not just the ducts.
Ducts work with your insulation and your equipment. We make sure everything is sized and sealed correctly so your system runs efficiently and your home stays comfortable.
