Furnace repair in New Germany starts with a $79 trip charge, waived once you approve the work, for low basements and brick chimneys. Older houses here have low basements and a brick chimney, so a weak draft is the first thing to rule out.
Low basements shape furnace repair in New Germany. In early-1900s story-and-a-halfs and small farmhouse-style homes, the furnace often sits under a beam with barely enough room to pull the burner door, and a horizontal unit may hang from the joists. Tight access means filters get skipped, and a packed filter is what trips the high limit on a January night.
The single brick chimney is the other thread. It has outlasted several furnaces and water heaters, and mortar and liner debris can collect at its base, where it chokes the draft. A weak draft shows up as a tripped rollout or spill switch, or as a furnace that runs and then locks out. Out on the Camden Township farmsteads, propane furnaces stop when the tank runs dry, and the supplier usually has to leak-check the system before relighting. After that, we handle whatever the furnace itself needs.

National averages (HomeGuide, 2026), not our prices: a variable-speed (ECM) blower motor $800–$2,300, an igniter $100–$250, a flame sensor $80–$250. More in the furnace repair cost guide.

Likely a flame rollout switch. It opens when flames roll out of the burner area instead of traveling up through the heat exchanger, which can happen when the chimney or flue is blocked or the heat exchanger is cracked. Don't keep resetting it. In older New Germany houses we check the chimney base and flue connector first, then the heat exchanger, and measure carbon monoxide before relighting.
A little. Horizontal furnaces use the same parts as upright ones, but the burners, inducer and control board sit at awkward angles, and a high-efficiency model's condensate trap has to be set up for that position. A trap installed for the wrong orientation holds water and trips the pressure switch. The repair price is still flat-rate and written before we start, however long the access takes.
