HVAC installation and ductwork
Furnace, AC, and ductwork sized to the actual space — not to whatever was there before.
Oversizing is the most common mistake in this city
San Antonio summers make people want the biggest unit they can afford. That is usually the wrong call. An oversized air conditioner cools the air to the thermostat setpoint fast and then shuts off — before it has run long enough to pull humidity out. You end up with a house that is cold and clammy, a compressor that short-cycles itself toward an early failure, and a bill that is worse than a correctly sized system would have produced.
The fix is a load calculation that accounts for your square footage, insulation, window area and orientation, and duct condition. It takes longer than reading the label on the old unit. It is the difference between a system that works and a system that merely runs.
The ducts matter as much as the box
A new high-efficiency system attached to leaking ducts in a 140-degree attic delivers a fraction of what you paid for. Duct leakage, crushed flex runs, and missing insulation are extremely common in older San Antonio homes, and they are usually cheaper to correct than the efficiency upgrade people reach for first.

Common questions
- What size air conditioner do I need?
- The only honest answer comes from a load calculation on your specific house — square footage, insulation, windows and their orientation, ceiling height, and duct condition all change it. A contractor who sizes off the old unit is repeating whatever mistake was made last time. Bigger is not better here; oversized units cool without dehumidifying and cycle themselves to death.
- Should I replace my ducts when I replace the system?
- Often yes, and it is worth checking before you decide. Leaking or crushed ducts in an uninsulated attic can throw away a serious fraction of your capacity, which means you paid for efficiency you never receive. We inspect the duct system as part of the quote so the decision is based on what is actually up there.
- How long does an AC replacement take?
- A straightforward changeout is typically a single day. Adding ductwork, relocating equipment, or correcting returns extends it. We tell you which of those apply after looking at the system rather than quoting a day and discovering otherwise.
