Furnace fires up, burns for a few seconds, then shuts off and tries again? That specific pattern usually comes down to one small part costing a few dollars. It is the most common heating failure there is, and it is very fixable. Justin or Colby will find out whether that is your fault or something else.
No heat in winter, no cool in a heat wave, busted lines. We answer the phone day or night, weekends included.
If your furnace lights, runs for a few seconds, then drops out and tries again, you are almost certainly looking at the flame sensor. It is a thin metal rod sitting in the burner flame whose only job is to confirm a flame is actually there. If it cannot see the flame, the control board shuts the gas off, which is exactly what you want it doing.
The catch is that it slowly coats with a film from combustion, and once that film builds the sensor stops reading properly even though the burner is lit perfectly. Industry parts data puts flame sensors at the top of the heating season failure list, roughly a quarter of winter part orders, and it is one of the least expensive components in the whole furnace. Cleaning or replacing it is usually a short visit. It is a good example of why diagnosis matters more than assuming the worst.

Furnaces fail in recognisable patterns. Knowing which one you have tells you a lot about the size of the job.
This is the flame sensor pattern and it is the most frequent heating failure we see. The burner lights properly, the sensor fails to confirm it, and the board shuts the gas down as a safety measure. Cleaning or replacing that one small part usually solves it outright. It is the good news version of a no-heat call.
Often a badly clogged filter. The burners overheat, the limit switch cuts them, and the fan keeps going to cool things down. Change the filter and see. If it repeats, the airflow problem is deeper than the filter.
Check the breaker, then the switch on or beside the furnace that looks like an ordinary light switch. They get knocked off during basement work and nobody connects the two. Then check the thermostat is calling for heat and its batteries are alive.
If your furnace vents through the side wall in white plastic pipe, check those outside terminations are clear of snow and ice. A blocked intake or exhaust shuts it down deliberately. A frozen condensate line does the same thing on a condensing furnace.
Stop and leave the house first, then call from outside. A cracked heat exchanger or a blocked flue can put combustion gases into the living space. This is the one category where guessing is not acceptable and no amount of urgency justifies waiting inside.
Press it once. If it locks out again, stop. Repeated resets push unburned oil into the chamber and make the eventual repair worse. Usually it is the nozzle, the oil filter, the pump, or a dirty CAD cell.
Heating parts fail on first demand. A furnace sits idle from April to October, then gets asked to run for the first time on a cold evening, and anything that was marginal in spring shows up immediately. That is why the first genuinely cold week of the year fills every schedule in Monroe County. The flame sensor that was becoming marginal last March finally fails in November, and it does so on the same night as everyone else's.
Henrietta has several distinct generations of housing in it. The town went from roughly three thousand people to fourteen thousand in the ten years after the war, Riverton was laid out in the early seventies, and construction has carried on since. A fifties ranch, a seventies Riverton home, and a recent build have different furnaces, different venting, and different failure patterns. That matters for diagnosis, because assuming the setup before looking at it is how faults get missed.
If we find a cracked heat exchanger, we are going to tell you plainly and we are going to recommend shutting the furnace down. That component separates combustion gases from the air moving through your house, and a crack lets those gases into the living space. It is not something to nurse through one more winter. It is also, honestly, the point at which replacement usually makes more sense than repair, and we will show you why rather than just asserting it.
The diagnostic is $99 and it is real work. We find the actual fault and give you a straight price before touching anything. No trip charge games, no quoting a replacement when a part has failed.
The make and model from the data plate inside the front panel, which is worth photographing now rather than reading out by torchlight later. Then the symptom in detail. Does it try to light and give up, or do nothing at all? Is the blower running? Any error light blinking on the control board, and how many flashes? That last one is genuinely useful, because those blink codes point straight at a fault category and mean the right part often arrives on the first visit.
