Furnace repair in Arlington starts with a $79 trip charge, waived when you say yes, in 1950s–70s ramblers and early-1900s two-stories. In the 1950s–70s ramblers, one central return can starve a furnace until the high-limit switch trips. Out on the farms, propane regulators that ice up give weak, sooty flames.
Most Arlington furnaces are on their second or third generation in houses built long before them. In the 1950s through 70s ramblers, the usual layout is one central return and a supply to each room, and a return that small can starve a modern furnace. The blower can't move enough air, the heat exchanger runs hot and the high-limit switch shuts the burners off, then the cycle repeats. A clogged filter makes it worse, so that's the first thing we check.
Near downtown, the early-1900s two-stories often still vent an 80% furnace into the old chimney, where a loose or rusted connector pipe can leak exhaust into the basement. On the farms around town, furnaces burn propane, and a regulator that ices up or drifts off pressure gives weak, sooty flames. In town, CenterPoint Energy has supplied natural gas since 1953.

That pattern usually means the high-limit switch is tripping because the furnace is overheating. In Arlington ramblers with a single central return, the furnace often can't pull enough air, and a dirty filter or closed bedroom doors tip it over. Start with a fresh filter. If it keeps cycling, we check temperature rise and duct pressure. A starved furnace is more common than a bad switch.
It depends on its age and what failed. An igniter, flame sensor or inducer on a 10- to 15-year-old propane furnace is worth fixing. A cracked heat exchanger on a 25-year-old unit usually isn't. If yours is near the end, have us price a new propane furnace with a cold-climate heat pump, which covers mild weather and cuts how much LP you buy.
