Real flame, real ambiance for Keller homes.

Because most Keller homes already have an existing masonry firebox—and often a gas stub already run to it from original construction—install costs here tend to land on the lower-to-middle end of what's typical nationally. A vented gas log set into an existing wood-burning fireplace runs roughly $1,500 to $3,500 installed. A full direct-vent gas insert—sealed, glass-front, and considerably more efficient—typically runs $3,500 to $7,000 depending on the unit and whether the gas line needs resizing. New construction or a remodel that requires framing a fireplace from scratch, with no existing gas line, can run $6,000 to $11,000. A local dealer will give you a firm number after seeing your firebox and gas line in person.

This is the single most common gas fireplace project in Keller. Most subdivisions built from the 1990s through today came standard with a masonry wood-burning fireplace, and a large share of homeowners never actually burn wood in them—Keller's mild winters, with an average low near 36°F, don't create much demand for it. Converting to a vented gas log set is the simplest path, usually $1,500 to $3,500, using the existing chimney as the vent. Upgrading to a sealed gas insert costs more but delivers real heat output and a tighter seal against North Texas summer humidity finding its way down an open flue.

Natural gas is the standard here—Atmos Energy serves essentially all of Keller, and the great majority of homes already have gas service for the water heater, range, or furnace. Propane shows up occasionally on larger, more rural-feeling lots at the fringes of the city or in unincorporated pockets of Tarrant and Denton counties where gas mains haven't been extended, but it's the exception rather than the rule. Almost every gas fireplace or insert on the market can be configured for either fuel, so availability rarely limits your choices.

Yes—most modern gas fireplaces with IPI (intermittent pilot ignition) run on a small battery backup that kicks in automatically if the power drops, which matters in Keller given that spring storms, hail, and occasional ice events knock out power more often than the cold itself does. Valor units take a different approach: their pilot generates its own electricity through a thermocouple, so there's no battery to remember or replace. Either way, ask your local dealer which ignition system a given unit uses before you buy.

A gas fireplace is a fully built-in unit framed into a wall—the right call for new construction or a room without an existing hearth. A gas insert is built to slide into an existing masonry firebox, which describes the vast majority of homes in Keller's established subdivisions, and it uses the existing chimney as its vent path. A gas stove is a freestanding cabinet-style unit that sits on the floor, more common in smaller rooms or additions with no existing masonry opening. Given how many Keller homes already have a builder-standard wood-burning firebox, an insert is usually the fastest and least invasive upgrade.

Yes—the City of Keller requires a building permit for gas fireplace installations, and any new or modified gas line work has to be performed by a licensed gas contractor as part of that permit. Most local hearth dealers handle the permit application and inspection scheduling as part of the installation, so it's rarely something a homeowner has to manage directly. Because there's no regional air-quality curtailment program here—unlike the wood-burning restrictions you'd find in some Western cities—the permit process is mostly about gas line safety and venting clearances, not emissions.

Vented (direct-vent) units draw combustion air from outside and exhaust it back outside through a sealed pipe—they're the most common choice and work in essentially any room. Vent-free gas fireplaces and log sets burn without any exterior venting, and Texas permits their use as long as the room meets minimum square footage requirements and the unit includes an oxygen depletion sensor. Vent-free units are popular in Keller specifically because they're cheaper to install into an existing masonry firebox that isn't already set up for direct venting—no need to run new pipe through the chase. That said, direct-vent units burn cleaner and put no moisture or combustion byproduct into the room, which matters more in a tightly sealed newer home. A local dealer can walk you through both for your specific fireplace opening.

An annual inspection is worth doing even though gas fireplaces need far less maintenance than a wood-burning setup. A technician checks the burner, pilot assembly, gas connections, and glass seal, and confirms the venting is clear—birds and wasps nesting in exterior vent caps is a real, recurring issue in North Texas. Most local service providers charge $125 to $200 for a standard annual visit, ideally scheduled in early fall before the first cool snap.

Wood-burning fireboxes exist all over Keller—mostly as a leftover builder feature—but wood as an actual heat source doesn't make much sense here. With an average winter low around 36°F and a mild, short heating season (compare that to Fargo, North Dakota, which logs a much longer, harsher winter), there isn't the sustained cold that makes cutting, storing, and burning cordwood worthwhile. Local oak, pecan, and mesquite are far more likely to end up in a backyard smoker than a fireplace. For homeowners with an existing wood-burning firebox, converting to gas logs or a gas insert gets the look and occasional-use warmth without the ash, smoke, or hassle of sourcing firewood.

Open fireplaces suck—literally. As the fire burns, it consumes air your furnace already paid to heat and pulls it out through the chimney, so the house is actually colder after the fire goes out than before you lit it. An insert fixes this: it seals the chimney, puts fixed glass across the front, and turns that hole in your house into a real heat source.

If it was installed more than 15 years ago, probably. Older gas fireplaces keep a standing pilot light burning all the time, and that little flame can cost a couple hundred dollars a year. Newer models use pilot-on-demand ignition—the pilot lights only when you use the fireplace and goes out when you turn it off.

For an average home—covering the fireplace, the vent pipe, and basic installation—a budget between $3,900 and $5,500 gives you a lot of options across wood, gas, and pellet. By the time you add finish work, gas line, and electrical, the average complete installation lands between $5,000 and $12,000 all-in. In a remodel or new build, a good rule is to put about 2.5% of the total project cost toward the fireplace.

If you're putting a fire in your house on purpose, it's best to work with an expert. Unless you're genuinely experienced in framing, gas line, vent pipe, and the national code on clearances to combustibles, have a professional do it—and ideally the same company that sells you the fireplace, so warranty, service, and liability all live under one roof.
