Furnace Installation & Replacement in Gramercy, LA
Louisiana winters are short, but that doesn’t mean your furnace gets a pass on performance. When temperatures drop, and your heat needs to fire up after months of sitting idle, the last thing you want is a system that’s on its last legs — or worse, one that was never properly sized for your home in the first place. A furnace replacement done right sets you up for years of reliable heat without emergency calls, climbing energy bills, or repairs that keep adding up.
Big Chief’s handles furnace installations and replacements across the River Parishes with the same approach we bring to every job: proper sizing, quality equipment, honest pricing, and workmanship we’re willing to stand behind. We service all makes and models, and as an independent Trane dealer, we can set you up with some of the most dependable heating equipment available.
Fast Financing Available
A new furnace is a real investment, and timing isn’t always on your side. Big Chief’s offers financing through Wells Fargo so you can move forward with a replacement without having to wait until the budget lines up perfectly.
Signs It's Time to Replace Your Furnace
Most furnaces don’t fail without warning. They slow down, get noisier, get less efficient, and start needing more attention before they finally give out. If your system is showing any of these signs, a replacement conversation is worth having:
A cracked heat exchanger in particular is something we take seriously — it’s a safety issue, not just a performance one, and it often makes replacement the only responsible path forward. Whatever the situation, we’ll give you a straight assessment and let you make the call.
How Big Chief's Handles a Furnace Installation
A furnace replacement starts before any equipment shows up at your door. The first step is making sure we’re recommending the right size system for your home — one that’s matched to your square footage, your ductwork layout, your insulation, and how your home actually behaves in cold weather. Skip that step, and you end up with a furnace that either short-cycles because it’s too powerful or runs nonstop because it can’t keep up.
Once we’ve confirmed the right fit, our NATE-certified technicians handle the full installation — removing the old unit, installing the new equipment, making all necessary connections, and thoroughly testing the system before we call the job done. Every furnace we install is backed by Big Chief’s for the life of the system. That’s not a line in a contract somewhere — it’s how we’ve operated since 2001, and it’s not changing.

Furnace Installation & Replacement FAQs
Here are the questions we hear most from homeowners getting ready for a new furnace.
Age and repair history are usually the clearest indicators. A furnace that’s under 15 years old and well-maintained is often worth repairing, depending on the problem. One that’s older, has needed repeated repairs, or is facing a major component failure, like a cracked heat exchanger, is usually better off replaced.
A good rule of thumb: if the repair cost is approaching half the price of a new system, replacement is almost always the smarter long-term investment. We’ll walk you through the math honestly and help you make the call that actually makes sense for your situation.
Several things go into the final cost of a furnace installation. The most significant ones include:
We’ll cover all of this during your free estimate, so there are no surprises when it’s time to get started.
Most furnace replacements are completed in a single day. A straightforward swap — same location, existing ductwork in good condition, no major modifications needed — typically goes smoothly and quickly. More involved installations may take longer, particularly if ductwork adjustments or electrical upgrades are included.
Your technician will give you a realistic timeline before work begins, so you know what the day will look like.
Furnace sizing isn’t something you want to guess at. A unit that’s too large will short-cycle — turning on and off too frequently — which wastes energy and shortens the system’s lifespan. One that’s too small will run constantly, leaving parts of your home cold. Factors that go into proper sizing include:
Our technicians perform a proper load calculation before recommending any system, which is the only reliable way to make sure you’re getting a furnace that actually fits your home.
Yes. When Big Chief’s handles your furnace replacement, removing and disposing of the old unit is part of the job. You won’t be left trying to figure out what to do with a decommissioned furnace sitting in your utility room.
We handle the full process, start to finish — out with the old, in with the new, tested and running before we leave.
