Air Duct Cleaning
Our negative-air machine seals onto the main trunk duct and puts the whole system under suction first. Then each run is scrubbed individually, so years of dust and debris travel one way only — out of the ducts and into the machine. The visit also covers the returns, where a leaking return has often been pulling attic dust straight into the system. That is air duct cleaning in LaCoste, TX, done the way it should be.

A duct system in LaCoste 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.
A LaCoste attic on a summer afternoon is one of the harshest places any building material works. Flex duct jackets age fast, tape dries and lets go, and straps stretch - so joints separate quietly overhead while the AC runs longer every year to hold the same temperature.
From spring to well past the start of football season, LaCoste 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.
Dry, windy stretches blow fine soil dust across Medina 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-story LaCoste 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.

Before blaming the unit, check the ducts. In LaCoste, 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.
Every few years for most LaCoste 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.
It sits at the end of the longest attic run, and that run sags, kinks or leaks on the way in most Medina 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.
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 LaCoste culprit, and mastic sealing is the lasting repair.
In LaCoste, 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.
