How much does it cost to swap an old gas insert for a new one?
Swapping an old gas insert for a new one typically costs meaningfully less than a first-time installation, because the expensive groundwork — the gas line, the chimney route, the electrical — already exists. Your real costs are the new insert itself, liner work if the old liner doesn't match, and finish trim. An exact number takes a free in-home estimate, and ours are genuinely free.
Why a swap beats starting from scratch
The costly parts of any gas insert project are the ones you can't see: running a licensed gas line, establishing the liner path up the chimney, getting power to the unit. In a swap, all of that was paid for the first time around. What's left is the appliance, the labor to set and connect it, and whatever it takes to make the new unit look at home in your masonry opening. That's why we tell folks a swap is mostly an appliance decision, not a construction project.
The three things that move a swap quote
First, the liner. Every insert we install gets a correctly sized chimney liner, and if the existing one is the wrong diameter for the new unit or has deteriorated, replacing it is the biggest variable in the job. Second, fit and trim — old and new inserts rarely share exact dimensions, so faceplates and surround panels bridge the difference, and larger gaps mean more finish work. Third, fuel: on the natural-gas mains through Asheville, Hendersonville, Fletcher, and Arden it's usually plug-and-play, while propane setups out toward Fairview, Candler, and Brevard need the right orifices and pressures dialed in from the start — get that wrong and the new unit soots.
What two decades of insert progress buys you
If your insert dates to the 2000s, a modern replacement is a real upgrade: sealed units commonly run 70 percent efficient or better, ignition systems are smarter, and the flame presentation has come a long way. In our lineup, the Napoleon Oakville X4 and the Kozy Heat Chaska 25L — blower standard — are the two we walk people to most.
