The Right Size Beats the Cheapest Quote

The most common installation mistake isn’t a bad unit — it’s the wrong size. We run a proper load calculation on every install.

Oversized short-cycles and never dehumidifies; undersized runs all day and never catches up. We size it to your actual home.

When to Replace vs. Repair

The rule of thumb: multiply the system's age by the repair cost. Over $5,000 — replacement is worth a conversation. Under — repair is usually right. Moorhead will tell you the honest answer. If the system has life left in it, we say so — even when repair means a smaller invoice for us.

A customer in Schertz called because another company told them their 9-year-old system needed full replacement — $9,000 installed. Justin went out. Failed capacitor and refrigerant leak at a service valve fitting. Total repair cost under $300. Three to five more summers. That's a $8,700 difference, and the honest diagnosis was the repair.

Right-Sizing Matters

An oversized AC short-cycles — runs in quick bursts instead of long steady cycles. It cools but doesn't dehumidify, wears out faster, and costs more to run. An undersized unit runs constantly and never quite gets there. We do a proper load calculation before recommending any system. The right size is the right size, not whatever's most profitable.

What's Included in Every Install

Full system, all refrigerant, whip and disconnect, thermostat calibration, written performance test after startup. Permits pulled where required. We register the equipment warranty on your behalf at installation.

Brands We Install

All major brands — Carrier, Trane, Lennox, Rheem, Goodman, American Standard, and others. We don't push brand loyalty. We recommend what's right for your home's square footage, insulation, and ductwork.
