Follow the air into every room.

Every sag, crushed elbow and unsealed collar in that attic is cooling you paid for and never felt. We photograph it before anyone quotes it.

You get the readings either way
Camera inspection
01
✓Camera inspection

Photos from inside your own ducts before anyone quotes anything.

Leakage pressure test
02
✓Leakage pressure test

How much of your cooling ends up in the attic. This is the number that moves the bill.

Collars, plenum, boots
03
✓Collars, plenum, boots

Mastic where tape has failed. Every unsealed collar is paid-for air.

Sag, kinks, crushed flex
04
✓Sag, kinks, crushed flex

Runs supported and straightened; airflow balanced room to room.

Return path & filter cabinet
05
✓Return path & filter cabinet

Starved returns make a whole house feel weak. A media cabinet fixes the filter you forget.

Coil & plenum condition
06
✓Coil & plenum condition

Where moisture and biology actually live. Targeted UV only if it earns it.

Symptom → cause → fix

What it usually is, and what we do about it.

The common patterns we see across Bexar County. Yours gets diagnosed with gauges, not this table — but it tells you what to expect.

Tell us your symptom
SymptomUsual causeOur fix
Dust at registers Leaky return pulling attic air Seal returns, media filter
Musty when it kicks on Wet coil, plenum biology Coil clean, drain, targeted UV
One room always hot Long run, kink, missing return Re-route or add return
Bill high, air fine Supply leaking to attic Pressure test, mastic, re-insulate
Renovation dust Debris in trunks Clean once, then filter cabinet
02 / When it helps

Cleaning, sealing, or neither.

Duct cleaning is worth real money in some houses and worth nothing in others. We will tell you which one you are — with photos from inside your own ducts, not a stock brochure.

03 / The bigger number

Leaky ducts cool the attic, not you.

Cleaning makes the air nicer. Sealing makes the bill smaller. Every unsealed collar, crushed elbow and sagging run in that attic is cooling you paid for and never felt.

01
Seal and balanceMastic at the collars and plenum, runs supported and straightened, airflow balanced room to room, static pressure verified.
02
FiltrationA media cabinet moves you from a one-inch filter you forget to a filter that actually catches cedar pollen — without starving the blower.
03
Disinfection & UVFor coil and plenum biology, UV plus a coil cleaning. It is a targeted fix, not something every home needs.

Air quality questions, answered straight.

More of them, with numbers, on the questions page →

How often do ducts need cleaning?+

Most homes, rarely — and only when there is a reason: renovation dust, pests, water, or visible buildup. Anyone who tells you every year is selling, not diagnosing.

Will cleaning my ducts lower my bill?+

No. Sealing them will. Cleaning is about what you breathe; leakage is what you pay for.

What filter should I use?+

A pleated filter changed every 30 to 90 days, or a media cabinet if you want longer intervals. Higher MERV is not automatically better — a filter too restrictive for your blower starves airflow and ices the coil.

Does UV actually do anything?+

On a coil and in a plenum, yes — that is where moisture and biology live. It is not an air purifier for the whole house, and we will not sell it as one.

Can you fix one room that is always hot?+

Usually. It is normally a duct problem — length, sizing, a crushed run or a missing return — and it is fixable without touching the equipment.
