A duct system in Leon Valley 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.
From spring to well past the start of football season, Leon Valley systems run daily. That runtime moves a dust load through the house more times in one summer than a northern system manages in three years - which is why duct condition shows up here as dust on everything, all the time.
With no basements, Leon Valley ductwork lives entirely in the attic - long flex runs snaking over joists, sagging between straps and kinking at turns. A sagging run traps dust and slows airflow; a kinked one starves the room it feeds, usually the far bedroom.
Two-story Leon Valley 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.
Converted garages, casitas and room additions across Leon Valley often get ductwork tied in as an afterthought - undersized, unsealed or fed from the end of a trunk. Those rooms never match the house temperature until the run is sized, sealed and balanced properly.

Before blaming the unit, check the ducts. In Leon Valley, 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.
They hold the reservoir. Cedar, oak and grass pollen collect in the returns across their seasons and keep recirculating between them, so a Leon Valley house can feel pollinated in a month when nothing outside is blooming. Cleaning the trunk and returns removes that stored load.
It sits at the end of the longest attic run, and that run sags, kinks or leaks on the way in most Bexar 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.
In Leon Valley, sealing is usually where the savings live: cooled air leaking into an attic is a direct loss on every cycle of the longest cooling season in the country. We leak-check on every inspection and tell you plainly which work would pay off.

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.
