The half of the install you never see.

A right-sized coil and blower in a 140° attic decide the efficiency on the label — not the box in the yard. This is what a real install includes before the first screw.

You get the readings either way
Manual J load calc
01
✓Manual J load calc

Square footage, glass, orientation, insulation, duct condition. The size comes from your house.

Duct pressure test

✓Duct pressure test

How much of the new system will leak into the attic before we start.

Matched coil & blower
03
✓Matched coil & blower

Condenser, coil and air handler as the rated pair, so the label efficiency is what you get.

Acid from a dead compressor kills a new one. We do not gamble with it.

By scale against the nameplate, then verified with superheat and subcooling.

Mechanical permit pulled, inspection booked, warranty registered in your name before we leave.

Symptom → cause → fix

What it usually is, and what we do about it.

The common patterns we see across Bexar County. Yours gets diagnosed with gauges, not this table — but it tells you what to expect.

Tell us your symptom
SymptomUsual causeOur fix
Two quotes, thousands apart One skips the list above Line-item both, then decide
Cold but clammy house System oversized Manual J before a new box
New unit, old bill Unmatched coil or leaky ducts Match pair, pressure-test ducts
Upstairs never cools Duct sizing or no return Fix ducts before adding tonnage
Quote without a permit Not cheaper — inherited at sale We pull it and book inspection
02 / What a real install includes

Nine things a cheap quote leaves out.

Two quotes for “a 3-ton system” can differ by thousands, and the difference is almost never the box in the yard. It is this list.

03 / Sizing

Sized for your house, not for our invoice.

Bigger is not better. An oversized system satisfies the thermostat before it has run long enough to pull humidity out of the air, so you get a house that is cold and clammy, plus a compressor that short-cycles itself to an early grave.

05 / Frequently asked

Installation questions, answered straight.

More of them, with numbers, on the questions page →

How long does it take?+

A straight changeout is typically one day. Ductwork, electrical, a new pad or a difficult attic access can add time — you hear which applies before you sign.

Do you pull the permit?+

Yes, and we schedule the inspection. A quote that skips the permit is not cheaper; it is a problem you inherit when you sell.

Can I just replace the outdoor unit?+

Rarely a good idea. Modern condensers are rated with a specific coil and blower; mixing old and new gives up the efficiency you paid for and can void the warranty.

What about financing?+

In-house plans approved by us, plus Synchrony, Service Finance, Wisetack and GoodLeap with terms up to 15 years. Wisetack shows options on a soft credit pull.

Is a higher SEER2 worth it here?+

More often than up north. San Antonio runs its systems most of the year, so the efficiency tiers have far more hours to pay themselves back.
