HVAC System Replacement in Acadiana

Replacement is the one recommendation a contractor has the most incentive to push, so here is our honest rule of thumb: if the repair costs more than a third of replacement and the system is past about twelve years, replacement usually wins — especially given how many run-hours Louisiana puts on equipment. Below that, repair almost always wins. The other thing worth knowing is that sizing matters more than brand. An oversized system short-cycles, never runs long enough to pull humidity out of the air, and leaves a house that is cold and clammy at the same time — a genuinely common outcome here. We measure rather than match whatever was there before.

HVAC System Replacement questions

Our rule of thumb: if the repair exceeds a third of replacement cost and the system is 12 or more years old, replacement usually wins. Under that threshold, repair generally does. We give you both numbers and no pressure — the $99 diagnostic answers the question either way.

Regulation has moved the industry off R-410A onto lower-global-warming A2L refrigerants such as R-454B, which is what new equipment now ships with. It is mildly flammable, so it requires different handling, tooling and certification. Our technicians are EPA-certified for it, and any system we install is A2L-ready.

No, and this is the most common sizing mistake we find. An oversized unit satisfies the thermostat quickly, shuts off before it has removed meaningful humidity, and leaves you cold and clammy while cycling itself to an early death. Correct sizing comes from a load calculation on your actual home.

A straightforward changeout is typically a single day. Jobs involving ductwork modifications, a different equipment configuration or attic access can run into a second day. We tell you which one yours is at the estimate, not on the morning of.
