Reliable gas heat for Lehigh County's long heating season.

Most gas fireplace and insert installations in Lehigh County land somewhere between $3,800 and $10,500, depending on the unit, the venting path, and whether new gas line work is required. A direct-vent insert dropped into an existing Allentown or Bethlehem-area masonry fireplace that's already near a gas line sits toward the lower end. A new built-in fireplace for a remodel or addition—with framing, a full venting run, and a new gas line—lands in the middle to upper range. Homes on propane in the western townships that need a new tank set typically run higher once the tank installation is factored in. A local dealer will size the job accurately after seeing the space in person.

Yes, and it's a common project in Lehigh County given how many older homes around Allentown, Bethlehem, and Emmaus have original masonry fireplaces built for burning oak, hickory, or cherry cordwood. A gas insert typically slides into that existing firebox and vents through a stainless liner run up the existing chimney, so you keep the look of the original fireplace but gain a sealed, high-efficiency heat source. Homes already served by UGI natural gas usually see lower conversion costs than propane households that need new line runs or a tank installed. Either way, a local dealer will confirm the chimney is sound and sized correctly before running a liner.

Either works, and which one makes sense mostly comes down to where in Lehigh County you live. UGI Utilities serves natural gas through most of the Allentown-Bethlehem-Emmaus corridor and the denser boroughs along the Route 22 and 78 corridors—if your home already has a gas water heater or furnace, adding a fireplace is generally simple. Farther out in townships like Lynn, Heidelberg, and Washington, propane from a regional supplier is the standard option, either from an existing tank or a new one set specifically for the fireplace. Most gas fireplace models can run on either fuel; your installer just sets the correct orifice and regulator for the one you have.

Most modern gas fireplaces will, with the right ignition system. Units with IPI (intermittent pilot ignition) include a battery backup—typically AA batteries built into the unit—that keeps the fireplace lighting on demand even when the power is out. Valor fireplaces take a different approach: their pilot generates its own electricity through the thermocouple, so there are no batteries to remember at all. For Lehigh County winters, where an ice storm or nor'easter can knock out power for a day or more, that distinction is worth asking about when you're comparing units with a local dealer.

A gas fireplace is a fully built-in unit framed into a wall—the right choice for new construction or a major remodel in newer Lehigh Valley developments. A gas insert is built to slide into an existing masonry firebox, which is exactly what most older homes in Allentown, Bethlehem, and Emmaus already have, turning a drafty open hearth into a sealed, efficient heat source. A gas stove is a freestanding unit that sits on the floor like a wood stove but burns gas, and works well in a room without an existing fireplace. Most Lehigh County homeowners with an original masonry fireplace end up choosing an insert.

Yes—but the exact office depends on which municipality you're in, since Lehigh County is made up of dozens of boroughs and townships (Allentown, Bethlehem, Emmaus, Whitehall Township, and the rural western townships each handle their own permitting). Generally you'll need a building permit and a gas line permit, and the gas line work itself has to be done by a licensed gas-fitter. Most established hearth dealers coordinate the venting, gas line, and inspection with your local building department as part of the installation, so you typically don't have to track down the paperwork yourself.

Vented gas fireplaces—direct-vent or B-vent—pull combustion air from outside and exhaust the byproducts back outside through a sealed vent system. They're the cleaner, more universally code-compliant option. Vent-free units burn directly into the room without any outside venting; they're legal in Pennsylvania but come with strict room-sizing rules and oxygen depletion sensors, and they release some water vapor and combustion byproducts into the living space. For Lehigh County homes, direct-vent units are by far the more common installation and the one most local dealers steer customers toward, especially in tighter, well-insulated newer construction where indoor air quality matters more.

Plan on an annual inspection, ideally before the heating season starts in the fall. A technician will check the burner, pilot assembly, venting, and gas connections, and clean the glass and interior components. It's a lighter job than a wood chimney sweep, but it matters just as much for safety and for keeping the warranty intact. Local gas appliance service providers in the Lehigh Valley typically charge in the $150–$250 range for a standard annual visit.

Wood offers real heat output, lower fuel cost if you have access to the oak, hickory, maple, or cherry that's common on Lehigh County properties, and the ability to keep burning during a power outage with no dependence on the grid. Gas offers instant, thermostatic heat with no splitting, stacking, or ash cleanup—a fit for homeowners in Allentown, Bethlehem, and Emmaus who want the ambiance of a fire without the daily upkeep. A number of Lehigh County homes end up with both: a gas insert or fireplace for everyday use in the main living space, and a wood stove or fireplace elsewhere for backup heat and the occasional real fire.

An insert does two things: it seals the chimney completely, so you stop losing air you already paid to heat, and it radiates warmth into the room through the firebox and glass. Most add a heat-exchange fan that pulls cool room air underneath, wraps it around the hot firebox, and pushes it back out warm. Your home is more efficient before you've even lit the first fire.

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.

On average, a fireplace adds back to the home about the same amount you spent installing it. Add the monthly savings from heating the rooms you actually use instead of the whole house—often hundreds of dollars a year—and the value case is strong before you even count what a fire does for how your family uses the room.
