Local conditions

Selma ducts have Selma problems

A duct system in Selma cools through a brutal, months-long season from inside a superheated attic. This is what we actually find here, and what we check on every visit.

Cedar, oak and grass pollen

Texas pollen is famous for a reason - cedar in winter, oak in spring, grasses after that. Return ducts store each wave and recirculate it between seasons, so the house keeps a pollen reserve long after the outdoor count drops.

Construction dust in booming suburbs

Growth around Selma means subdivisions going up fast, and systems routinely run during drywall and paint to keep crews working. New ducts start life loaded with construction dust, and owners in fresh homes often notice gritty dust within the first year.

Dust storms and dry wind

Dry, windy stretches blow fine soil dust across Guadalupe County and into every house, through door gaps, attic vents and the system itself. It is abrasive, it loads filters quickly, and what passes the filter settles in the low spots of the trunk and returns.

Two systems, twice the ductwork

Two-story Selma homes usually carry separate upstairs and downstairs systems, which means two trunks aging on their own schedules. The upstairs system - all attic, all heat - almost always needs attention first, and it is the one driving the summer comfort complaints.

Questions

Asked the way Selma asks

Why does my AC run all day and still not cool?

Before blaming the unit, check the ducts. In Selma, separated attic joints and leaking returns are behind a large share of weak-cooling calls: the system loses cooled air overhead and pulls hot attic air in its place. An inspection shows both on camera, and sealing plus repair often restores cooling the equipment always had.

How do you clean the ducts - what is the process?

Our negative-air machine seals onto the main trunk duct and puts the whole system under suction first. Then each individual run is scrubbed on its own, so loosened dust travels toward the trunk and into the machine - never back into your rooms. We finish at the registers and show you the before-and-after on camera.

Why is the far bedroom always hot?

It sits at the end of the longest attic run, and that run sags, kinks or leaks on the way in most Guadalupe County homes. Air arrives weak and warmed. Tracing the run on inspection, then repairing, re-strapping and sealing it, is the usual fix - no larger AC required.

What are the signs my ducts are leaking?

Rooms that never reach the set temperature, an AC that runs long cycles on ordinary days, dust that returns quickly after cleaning and an attic hatch that feels cool when the system runs. Failed tape in attic heat is the standing Selma culprit, and mastic sealing is the lasting repair.

Do you clean ducts in commercial buildings here?

Yes - offices, restaurants, retail, medical suites and multi-unit buildings across Selma, scheduled around your hours. Commercial systems get the same method: the negative-air machine sealed onto the trunk, every run cleaned individually, and a camera record of condition.

Do you give prices over the phone?

No — and be wary of anyone who does. Every duct system is a different size and condition, so a phone price is a guess that changes at your door. Our inspections and estimates are free: a tech looks inside your actual ductwork first, then gives you one clear price before any work starts.
