Gas Heat That Keeps Up With Washtenaw County Winters.

Most gas fireplace or insert installations in Washtenaw County run somewhere between $4,000 and $10,000, with the spread driven mainly by venting complexity and whether new gas line work is needed. A direct-vent insert dropped into an existing Ann Arbor or Ypsilanti masonry fireplace that already has a nearby gas line sits toward the lower end. A new built-in gas fireplace for a remodel or addition—with framing, a fresh gas run, and exterior venting—lands in the middle to upper range. Homes on propane that need a new tank, or installations requiring a longer gas line extension from the meter, can push toward the higher end. A local dealer will give you a firm number after seeing the space.

Yes, and it's one of the most requested projects among Washtenaw County homeowners, especially in the older housing stock around Ann Arbor's Old West Side, Burns Park, and downtown Ypsilanti, where original masonry fireboxes are common. A gas insert typically slides into the existing opening and vents through a stainless liner run up the existing chimney, so you keep the look of the original hearth—oak or maple mantel included—while gaining push-button heat. Costs generally run $4,000 to $9,000 depending on the insert and whether the home already has a gas line nearby. If the fireplace has sat unused for years, expect the installer to also inspect the chimney liner before running new venting through it.

Either works, and which one you use mostly comes down to where you live in the county. DTE Energy runs natural gas mains through Ann Arbor, Ypsilanti, and most of the eastern townships; Consumers Energy covers stretches of the west, including parts of Manchester and areas near Chelsea. If your home already has a gas furnace or gas range, adding a fireplace usually means tapping into existing service. In unincorporated pockets of townships like Lyndon, Freedom, or Sharon where gas mains haven't been extended, propane is the standard fallback, either from an existing tank or a new one set up through a regional propane supplier. Most gas fireplace models can be configured for either fuel—the installer sets the correct orifice and regulator for whichever you have.

Most will. Gas fireplaces with intermittent pilot ignition (IPI) include a battery backup—typically AA batteries built into the control module—that keeps the unit lighting on demand even when the grid is down. Washtenaw County sees its share of ice storms and downed-line outages in a hard winter, so this matters. Valor fireplaces take a different route: their pilot assembly generates its own electricity through a thermocouple, so there are no batteries to remember at all. Ask your local dealer about the ignition system on any model you're considering, and if you go the battery-backup route, put a reminder on the calendar to swap them each fall before the first cold snap.

A gas fireplace is a fully built-in unit framed into a wall—the right call for new construction or a remodel without an existing hearth. A gas insert is built to slide into an existing masonry firebox, using the chimney as its vent path, which makes it the natural fit for Washtenaw County's older homes with original fireplaces. A gas stove is a freestanding unit that sits on the floor like a wood stove but runs on gas line, which works well in a room with no existing chimney or fireplace opening at all. Most homeowners converting an old wood fireplace in Ann Arbor or Ypsilanti end up with an insert; new-construction homes in Saline or Dexter subdivisions more often go with a built-in fireplace.

Yes. Within Ann Arbor and Ypsilanti, permits are pulled through the city's building department; in unincorporated townships, they go through the Washtenaw County Building Department. Gas fireplace installs typically require both a mechanical/building permit and a gas line permit, and the gas work itself has to be done by a licensed gas-fitter. Most local hearth dealers coordinate all of this as part of the install—venting, gas line, and inspection—rather than leaving you to schedule separate trades and inspections yourself.

Vented (direct-vent) gas fireplaces draw combustion air from outside and exhaust it back outside through a sealed pipe—they're the most common choice and the one most installers in Washtenaw County recommend by default. Vent-free units burn gas directly into the room with no outside venting; they're legal in Michigan under the state's mechanical code, but they come with strict room-size and ventilation requirements, and they release some water vapor and combustion byproducts into the living space. For drafty older farmhouses common in the county's western townships, that added humidity can actually be a plus; for a tightly sealed newer build, a direct-vent unit is usually the better call. Ask your dealer to walk through both options for your specific room.

Plan on an annual inspection, ideally in early fall before the heating season ramps up. A certified technician checks the burner, pilot assembly, venting, and gas connections, and cleans the glass and interior—a much smaller job than sweeping a wood chimney, but just as important for safety and efficiency. Local gas appliance service providers in the Ann Arbor and Ypsilanti area typically charge in the $150 to $250 range for a standard annual visit.

Wood still has a real following in the county, particularly on rural properties where oak, maple, birch, and ash are all locally abundant and easy to source or self-split. Wood also keeps working during a power outage, which matters through a Michigan ice storm. Gas trades that for convenience: instant on-off operation, no ash or creosote to manage, and consistent heat output without tending a fire—a natural fit for busy households near campus or long commuters in Saline and Dexter who want ambiance without the maintenance. It's common to see both in the same Washtenaw County home: a gas insert in the main living space for daily use, and a wood stove in a den, workshop, or vacation property for backup heat and the smell of an actual fire.

An insert is a fireplace that slides into a pre-existing wood-burning fireplace—if you don't have one, there's nothing to insert it into. A zero-clearance fireplace is built into a framed wall, which makes it the answer for remodels and new construction. Simple test: existing masonry fireplace means insert; blank or framed wall means zero-clearance.

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 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.

Yes—by creating a comfort zone. A furnace heats every square foot of the house just to warm the one room you're in; a gas fireplace on low burns roughly a sixth of the gas a typical furnace does. Set the furnace around 55–60 degrees as a baseline, then heat the rooms your family actually uses. Families who heat this way commonly save $20–$60 a month.
