Gas Inserts for Older Central New York Homes

Why Families Choose Gas Inserts

A gas insert slides into the masonry fireplace you already have and turns an open, drafty firebox into a sealed heater with a real flame. Central New York is full of farmhouses and village homes with original brick fireplaces that look wonderful and heat nothing—an open fireplace can pull more warm air up the chimney than it puts into the room. An insert closes that loop. Gas fires are consistent and controllable by design. You choose the fire's intensity.

Fit is the whole game. An insert is sized to your opening—height, width, and depth—and finished with a surround that covers the gap between the unit and the brick, so measure your firebox before you shop, or bring photos to the showroom and we’ll measure with you. Inside-fit models and slim trims keep the original brick or stone visible. The goal is to give an old fireplace its fire back, never to cover it up.

Every insert vents up the existing chimney through a new flexible liner, and every one needs a gas line to the firebox. Natural gas is piped directly to your home by a gas utility. Propane gas is stored on site in an above or below ground tank which is refilled by an LP gas provider. Our trained in-house team handles the liner, the gas, and a safe, code-compliant installation, and we service what we sell—the people who put it in keep it running. Price any insert below, then come see them burning in the showroom.

We purchased a propane fireplace from Hearths A'Fire and had little to no experience with installation or maintenance. The customer service here is exceptional. I cant say enough about a gentleman by the name of Brian. He has gone far above and beyond for me in any time of need. He's about as professional and personable as anyone I've encountered and has truly shown he cares. He recently came with another very helpful gentleman by the name of Luke, even when their schedules are packed, to help me resolve a maintenance issue. Im truly thankful for the customer service I've received from these folks. Highly recommended!

Common Questions

Common Questions About Gas Inserts

The questions every Central New York fireplace project runs into, answered the way we'd answer them on the showroom floor.

More questions & answers

How much does a gas insert cost installed?

Less than a built-in fireplace, usually, because the opening and the chimney already exist—the variables are the unit, the liner length, and the gas run. Every insert on this page carries a price tier, and the instant estimate narrows it to your project in about two minutes. Your in-home evaluation makes it exact.

Can you convert my wood-burning fireplace to gas?

Almost always. A gas insert drops into most masonry fireboxes and vents up the old chimney through a new liner, turning a drafty opening into real, controllable heat. We confirm the fit, the flue, and the gas supply at your in-home evaluation before anything is ordered.

Will an insert ruin my original brick or stone?

Not if it’s done right. Inside-fit inserts and trims measured to your opening keep the original surround visible—the insert sits inside the firebox, and the finishing panel covers only the gap. Bring photos to the showroom and we’ll show you what it would look like in your fireplace.

Does a gas insert need electricity?

Most light without it. The blower is the one part that needs power, so during an outage you get radiant heat without the fan. If that matters to you—and in Central New York it usually does—tell us and we’ll show you the models that do it.

Who installs it, and what about service afterward?

We install what we sell—our trained in-house team handles a safe, code-compliant installation with attention to detail—and we service what we sell, so we’ll be here long after installation to make sure everything works the way it should.
