The Little Alsace of Texas — Castroville's historic Alsatian homes and newer subdivisions alike run AC nearly year-round this far south.
Castroville sits where Hill Country pollen meets South Texas heat and humidity. That combination loads ductwork with allergens, feeds mold in damp sections, and makes your system push harder for the same comfort — which is exactly why local homeowners stay on a regular service rhythm.
Simple, honest, and done in one visit.
We inspect your duct system and show you photos of the leaks and disconnected joints we find.
You get a clear, itemized quote. Nothing is sealed — or charged — until you approve it.
We seal joints, seams, and connections with mastic systems built to last in Texas attic heat.
We re-check airflow room by room so you can feel the difference where you actually live.
Every home is different, so we inspect first — free — show you photos of what we find, and give you one firm written quote. The price we quote is the price you pay.

What Castroville homeowners ask us most.
It can — and booking sealing together with your $99 duct cleaning in Castroville is the most efficient route, since the system is already open and inspected.
The U.S. Department of Energy estimates typical duct systems lose 25–30% of the air they carry through leaks and poor connections. In a Castroville home running AC most of the year, sealing those leaks is often the fastest payback in the whole system.
Every Castroville home is different, so we inspect first and give you an honest written quote before any work. The inspection itself is free, with photos and zero pressure.
Often, yes. Leaks on the return side pull attic and wall-cavity dust straight into your air stream. Sealing those gaps in your Castroville home can noticeably cut the dust that settles on furniture.
