Expert AC Installations in Gramercy, LA

Big Chief’s takes the guesswork out of the process by sizing your system correctly, installing it properly, and backing it for the life of the unit.
As an independent Trane dealer, we have access to some of the most reliable, energy-efficient equipment available. We also work with other brands, so if you have something specific in mind, we’ll let you know whether it’s a good fit for your home and get it installed the right way.

How Big Chief's Handles an AC Installation
Getting an AC installation right starts well before the equipment shows up. Our process begins with a proper load calculation to determine the exact size system your home needs, based on square footage, insulation, layout, and local climate. Skipping this step is one of the most common mistakes in the industry, leading to systems that wear out faster and cost more to run.
Once the right system is chosen, our NATE-certified technicians handle the full installation, from setting the equipment and running the refrigerant lines to wiring the thermostat and testing the system before we leave. Every installation is backed by Big Chief’s for the life of the system, so your investment is protected long after the job is done.

AC Installation FAQs
Here are some of the questions we hear most from homeowners getting ready for a new AC installation.
Most AC installations are completed in a single day. Larger homes or more complex setups can occasionally take a bit longer, but your technician will give you a realistic timeline before work begins.
We’ll also make sure the system is fully tested and running correctly before we leave, so you’re not left with questions on day one.
The cost of an AC installation depends on several variables. A few of the biggest ones include:
We’ll walk you through all of this during your free estimate, so there are no surprises when the job is done.
The right size depends on more than just square footage. Factors like ceiling height, insulation quality, window placement, and the layout of your home all play a role in determining what size unit will keep your home running efficiently.
Our technicians perform a full load calculation before recommending a system, which is the only reliable way to make sure you’re getting the right fit. A system that’s too large will short-cycle and wear out faster, while one that’s too small will run constantly and still struggle to keep up.
Not always, but sometimes. If your ductwork is old, leaky, or poorly designed, a new AC system won’t perform the way it should, regardless of how good the equipment is. Here’s what we look at when evaluating your ducts:
If duct replacement is needed, we’ll let you know upfront and explain why before any additional work is added to the project.
Trane has a strong reputation in the industry for building reliable, long-lasting equipment, and that reputation holds up in the field. Their systems tend to run efficiently, handle heavy use well, and come with solid manufacturer warranties.
That said, the best system for your home depends on your specific needs and budget. As an independent Trane dealer, we can walk you through their lineup and help you decide if it’s the right fit, with no pressure either way.
