Step 1 of 3: Equipment

Nine months of the year, a furnace here is running. September through May, it rarely gets a real break, and that's a long season to ask a machine to hold up without a problem. The igniter, the blower motor, the heat exchanger, all of them see more hours than they would almost anywhere else in the country. More hours mean more cycles, and more cycles mean parts wear down sooner than you'd expect. When something starts acting up, it's usually not bad luck. It's the furnace showing what nine months a year does to it.

Gas Here Runs $13.12 per Million Btu, and This Furnace Burns It All Winter

A furnace that's cycling too much or struggling to hold its temperature is burning gas the whole time it does it. At $13.12 per million Btu, a furnace that's working harder than it should is a cost you'll see on the bill before anyone tells you what's wrong. Waiting a few weeks to get it looked at means a few more weeks of paying for that inefficiency. If a repair can get it running the way it should, the sooner that happens, the sooner the bill reflects it. If the problem is bigger than a repair, that's worth knowing before another cold month runs up the cost of a decision you haven't made yet.

Know What You're Repairing Before You Pay For It

If your furnace came with the house, ask the contractor straight out how much life it has left before you pay for a major repair. A furnace that's already been replaced once, or is old enough that it should have been, is worth sizing up against the cost of fixing it. That's a fair question to put to whoever comes out to look at it.

Nine Months a Year Adds Up to More Than a Guess

Nine months of heat means nine months of wear, and that's already been said. What it means for the repair in front of you is this: get the actual cause written down, not just the symptom. A furnace that short cycles or won't hold a temperature has a reason, and the reason is usually one part, not the whole unit. Ask the contractor what failed and why, not just what it costs to fix it. If that part is worn from the hours this furnace puts in every winter, the part next to it has seen the same hours.

What a Bad Igniter or Flame Sensor Looks Like

A furnace that clicks and tries to start but won't catch, or starts and shuts off within a few seconds, is usually telling you the igniter or flame sensor has gone bad. The igniter has to glow hot enough to light the gas, and a cracked or weak one can't get there every time. The flame sensor checks that a flame is actually burning, and once it's coated or worn, the furnace shuts itself down rather than run without that check. Both are common failures, and neither means the furnace itself is done.

Noises and Smells Worth Acting On Fast

A bang when the furnace starts usually means gas is building up in the burner before it lights, then catching all at once. A screech points to the blower motor or its bearings. A burning smell the first time it runs after a break is normal dust burning off, but a burning smell that doesn't go away, or any smell of gas, means shut it down and get someone out. These aren't symptoms to watch and wait on. They're the furnace telling you a part is already failing.

A new furnace would cut about $180 a year off heating for a typical Bradford County home.

  • An older furnace$930 a year

Repair makes sense when one part has failed and the heat exchanger is sound.

Replacement makes sense when the heat exchanger is cracked or the furnace keeps needing parts.

A diagnostic visit starts before any panel comes off. A contractor will ask what the furnace is doing, when it does it, and what changed right before it started. Then they'll run it through a cycle and watch. They'll check the flame, which tells them a lot by its color and shape alone. A steady blue flame means it's burning clean. Yellow or flickering points to a combustion problem, and that gets checked further before anything else happens, since that affects whether the furnace is safe to leave running. From there they'll test the parts that fail most, the igniter, the flame sensor, the flame itself, often with a meter rather than a guess. They'll pull the filter and look at the blower wheel, since restricted airflow shows up as symptoms all over the system that have nothing to do with their real cause. By the end, the goal isn't just a part to replace. It's knowing why that part failed, so you're not back here again in a month.
