What a December breakdown in a Lititz rowhouse taught one Lancaster family and what it
means for the rest of us.

It was the third week of December when Carol noticed the house wasn’t warming up the way it usually did. She turned the thermostat up a degree, then another. The furnace kicked on; she could hear it, but by nine in the morning the downstairs still felt off. By noon, it had stopped altogether.

Carol’s house is a 1940s brick home on the north end of Lititz. Like a lot of homes in Lancaster County, it’s well-built, full of character, and heated by a system that had been quietly doing its job for years without anyone paying it much attention. When the technician arrived and pulled open the furnace panel, the problem was obvious to him, though invisible to her: a cracked heat exchanger, a dirty burner, and an air filter so clogged it had practically sealed itself shut. The system had been working against itself for a long time. The December breakdown was just when it finally gave up.

“The part that surprised her,” says the tech who made the call, “was when I told her the furnace had probably been running at half its efficiency for at least two seasons. She’d been paying for heat she wasn’t getting.”

This Is More Common Than You Think

Carol’s situation isn’t unusual. Across Lancaster County, in the Georgian townhouses of downtown Lancaster, the Victorian rowhouses of Ephrata, the farmhouses out toward Strasburg, thousands of families heat their homes with systems they’ve never had assessed and rarely have serviced. Not out of carelessness. Just out of the assumption that if the heat is coming on, everything must be fine.

But a furnace that’s “working” and a furnace that’s working well are two different things. A system running at 65% efficiency, common in homes with older equipment or years of deferred maintenance, is burning roughly a third more fuel than it needs to produce the same amount of heat. That difference doesn’t show up as a sudden spike. It shows up as a slow, steady bleed on every bill through every winter.

Lancaster’s housing stock makes this particularly worth paying attention to. The county’s National Historic District alone contains more than 13,000 buildings, most of them built in the 1800s. These homes were constructed long before anyone thought about BTU efficiency ratings. They are beautiful and worth preserving, and they require a little more attention to heat well.

What the Well-Heated Homes Have in Common

After years of service calls across the county, a pattern becomes clear. The homes that run most efficiently aren’t always the newest or the most recently renovated. They’re the ones that have simply been paid attention to. Filters changed on a regular schedule. An annual tune-up in the fall, before the cold sets in. Small noises and uneven heat addressed when they first appear, not six weeks later.

The homes that cost the most to heat and tend to have the expensive emergencies are the ones where the system has been treated like furniture. Assumed to just work. Left alone until it doesn’t.

A heating system that hasn’t been calibrated in years isn’t visible from the living room, but it shows up on the fuel bill. And it gets worse and more expensive to fix the longer they go unnoticed.

The Signs Worth Knowing

Most heating systems give warning before they give out. Rooms that heat unevenly. A furnace that cycles on and off more than it should. A pilot light that burns yellow instead of blue. Unfamiliar sounds like a persistent hum, a rattle, a click that wasn’t there last winter. These aren’t quirks. They’re your system asking for attention.

The other thing worth knowing: if you don’t know your system’s efficiency rating, that’s worth finding out. Systems built before 2000 often operate at 60–80% AFUE (Annual Fuel Utilization Efficiency). Modern high-efficiency systems routinely reach 95–98%. For a home with aging equipment, that gap is worth a conversation even if the answer isn’t a full replacement right now.

And for most homeowners, the single highest-return thing they can do is also the simplest: schedule a tune-up in the fall, before the first cold snap, and keep doing it every year. A technician will clean the burners, test efficiency, check for cracks or leaks, and catch problems while they’re still small. This one habit, done consistently, extends equipment life and reduces fuel waste more than almost anything else.

The Same Instinct, Applied Indoors

There’s something fitting about a county so defined by stewardship of its land, its waterways, its historic buildings while also being a place where people take care of what’s inside those buildings. Lancaster has always understood that things worth having require tending. A working farm. A covered bridge. A 100-year-old brick home on a quiet street in Lititz.

A heating system is no different. It’s not the most romantic part of the house. Nobody photographs the furnace. But it’s what makes the house livable in January, and treating it with the same steady, practical attention that Lancaster has always been good at is what keeps it working when you need it most.

Carol got her heat back in time for Christmas. She’s already scheduled her tune-up for next October.
