Why It Matters Here

Air Quality
in San Marcos

Master-planned communities like Blanco Vista and the 55-plus Kissing Tree brought a wave of new construction with builder-grade systems. Same story as everywhere — sized to a price, weak in a Texas August. We run a load calculation and fix the airflow once the warranty runs out.

That is why indoor air quality is not an upsell to us — it is part of keeping a San Marcos home genuinely comfortable. We measure humidity and airflow, then recommend only the equipment that earns its place.

Indoor Air Quality in San Marcos — Questions

The AC controls temperature, not air quality. Hays County humidity, dust, and pollen need dedicated equipment — a dehumidifier, better filtration, duct sealing, or a UV light. We measure what your San Marcos home actually needs instead of selling all of it.
It depends on the symptom. Sticky air points to a dehumidifier; a musty smell to a UV light on the coil; dust and allergies to filtration or duct cleaning; stale air in a tight new home to an ERV. We will tell you the one that fixes your problem, not the whole catalog.
Both. Cleaning clears built-up dust and allergens; sealing stops conditioned air from leaking into a San Marcos attic. They solve different problems, and we are honest about which one yours needs.
For the right problem, yes — a dehumidifier that fixes a clammy house, a UV light that stops recurring mold, sealing that cuts the bill and evens the rooms. We quote it flat and only recommend what earns its place in your San Marcos home.

“Bought a 1920s home near the Square and the wiring was a patchwork. Moorhead brought it up to code, kept all the original charm, and pulled the permit. They clearly respect old houses.”

Eleanor B.

“I manage rentals by the university and Moorhead is the only crew that tells me straight what needs fixing and what does not. Saved me from a new system a tech at another company swore I needed.”

Greg P.
San Marcos, TX

“Our house by the river was always muggy. They added a dehumidifier and sealed the ducts, came up from Seguin same week, and the price matched the quote exactly. Comfortable for the first time.”
