AC Installation & Replacement by Moorhead Service Company in San Marcos, TX Right-sized, not oversized
Sized to Your Home

The Right Size Beats the Big Size

An oversized AC short-cycles, never pulls the humidity, and wears out early. An undersized one runs forever and never catches up. We measure your San Marcos home — square footage, windows, insulation, ductwork — and size the system to it.

Then we quote it in writing, all-in, before any work starts.

AC Replacement in San Marcos, Done Right

A new system is a 15-year decision. Here is how we make sure yours fits your San Marcos home instead of the installer's schedule.

A Real Load Calculation

We run a proper load calculation, not a rule-of-thumb guess off the old unit's label. Half the systems we replace were oversized to begin with — which is exactly why the house felt clammy and the bills ran high.

Written, All-In Pricing

You get the price in writing before we start — equipment, labor, permit, and haul-off of the old unit. No "starting at," no surprise add-ons when the truck shows up in San Marcos.

High-Efficiency Options That Pay Off

A higher-SEER system can meaningfully cut the cooling side of your bill through a Hays County summer. We show you the real payback math and let you decide — we are not working a quota.

Repair vs. Replace, Honestly

If your system is repairable and worth repairing, we say so. We are not going to push a $9,000 replacement on a unit that needs a $275 contactor. Replace when it is 10+ years old and the repair tops half the replacement cost — otherwise, fix it.

Why San Marcos Homes in Particular

The older neighborhoods around Belvin Street and downtown have homes that predate central air entirely. That means undersized panels, two-prong outlets, ungrounded circuits, and sometimes knob-and-tube still in service. We modernize it safely and pull the City of San Marcos permit so it is documented for resale.

AC Installation & Replacement in San Marcos — Questions

It varies too much by system size and home to quote a fixed number honestly — which is why we do a free in-home load calculation first, then put an all-in price in writing. What we promise is no "starting at" games and no surcharge for San Marcos.
A real load calculation — square footage, windows, insulation, ductwork, orientation. We measure rather than copy the old label, because a lot of older San Marcos systems were oversized, and that is what made them uncomfortable.
Rule of thumb: if it is 10+ years old and the repair costs more than half a replacement, replace it. Under that, we fix it. You will get the honest call, not the bigger invoice.
Yes. A proper AC change-out is permitted and inspected, and we handle it. Skipping the permit is how it comes back to bite you at resale.

“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.”

“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.”
