A duct system in Terrell Hills 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.
When attic joints separate, a Terrell Hills system spills cooled air into the one space that never needs it. The rooms below drift warm, the unit runs near-constantly on the hottest days, and the cause sits overhead: leaks that sealing fixes for good.
Two-story Terrell Hills 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.
A leaking return in an attic pulls superheated, dust-laden attic air into the system every cycle, bypassing the filter. The AC fights hotter return air than it should ever see, rooms cool slowly, and the fix is sealing the return - a duct job, not an equipment job.
Converted garages, casitas and room additions across Terrell Hills 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.

Every few years for most Terrell Hills homes - sooner in new builds with construction dust, homes with pets, or households fighting cedar and oak allergies. The runtime here is so long that loads build faster than in most of the country. We camera-inspect free and show you your own trunk before recommending anything.
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.
They hold the reservoir. Cedar, oak and grass pollen collect in the returns across their seasons and keep recirculating between them, so a Terrell Hills house can feel pollinated in a month when nothing outside is blooming. Cleaning the trunk and returns removes that stored load.
In Terrell Hills, 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.
