Attic ducts are a San Marcos problem because of how the houses were built. A mix of smaller older homes and standard suburban attic systems. Some rentals have been ‘repaired’ with the cheapest available part. Humidity near the river corridor makes moisture control as important as the thermostat number.
San Marcos has campus rentals, older houses, and newer subdivisions on the edges. River-corridor humidity means an oversized system can hit the setpoint and still leave the house damp. Rentals add deferred maintenance: filters, drains, and contactors that should have been replaced a year ago.

Systems that cool the thermostat and leave the air damp
Short-cycling equipment does not dehumidify. In San Marcos that feels like a failed air conditioner even when the supply air is cold.
What the visit includes

- Visible flex, splices, and plenum connections

How we handle the job
01Map the unhappy rooms
We need to know which supplies serve them, not just which thermostat is on the wall.
02Measure, then recommend
A disconnected branch, a crushed run, and a system that is simply too small look different once we test.
03Repair the duct and retest the room
The job is done when the room is closer to the rest of the house, not when a length of flex has been replaced on principle.

We need to know which supplies serve them, not just which thermostat is on the wall. A disconnected branch, a crushed run, and a system that is simply too small look different once we test.

If rooms are uneven, start with repair and leakage. Cleaning does not reconnect a supply or un-kink a run. If the ducts are intact and you want debris removed, we will say whether cleaning is useful in that system.
No. A new condenser still has to push air through the same attic. We quote needed duct work with the replacement so you are not surprised after the install.
Closing a lot of supplies raises static pressure and can freeze a coil or make the blower loud. Tell us which rooms you want unused and we will look at a better way to balance them.
