  "tldr": "Don't authorize a replacement while the technician is standing there. Ask for the failed part named in writing, photographs of the fault, and the red tag if the unit is condemned — no paperwork means no condemnation.

  "faq": [
    {
      "q": "The technician is here right now and wants a decision. What do I actually say?",
      "a": "\"I'm not authorizing a replacement today. Please write up the diagnosis with the failed part named, send me the photos, and email me the quote — I'll come back to you tomorrow.\" You do not need a reason, an argument, or a counter-offer. A company that keeps pushing after that sentence has told you something useful about itself."
    },
    {
      "q": "They say it's unsafe and they have to shut it down. Can they do that?",
      "a": "A technician can shut off and tag an appliance they believe is unsafe, and a gas utility can lock a meter. That's legitimate. What makes it verifiable is paperwork: a red tag or condemnation notice identifying the unit, the fault, and the company. Ask for it before they leave. If there is no tag and no written condemnation, the unit was not condemned — it was quoted."
    },
    {
      "q": "How old does a system have to be before replacement is the honest answer?",
      "a": "Fixr puts furnace life at 15 to 20 years, with electric models reaching 20 to 30 and oil up to 25; air conditioners at 10 to 20 years; and tank water heaters at 10 to 15 with regular flushing, though its repair guide treats eight to ten as typical. Inside those windows, a major repair on a unit near the end is genuinely poor value. A ten-year-old furnace with a failed igniter is not."
    },
    {
      "q": "What's the 50% rule?",
      "a": "Fixr states it directly on its AC repair guide: if the repair costs more than 50% of replacement, replacing is probably the better long-run choice. Its water heater guide uses a flat threshold instead — a repair quoted at $1,000 or more when a new heater runs $600 to $1,500 installed. Both are rules of thumb, and both cut the other way more often than people expect: at $2,800 to $7,500 for a new furnace, half is $1,400 to $3,750, which is above almost every furnace repair Fixr lists."
    },
    {
      "q": "How do I ask for a second opinion without getting another sales pitch?",
      "a": "Call a company that charges a flat diagnostic fee and ask two questions before booking: do your technicians earn commission on equipment sales, and do you waive the diagnostic fee if I buy a system. Commission-paid technicians and waived-if-you-buy diagnostics both mean the person diagnosing your furnace gets paid more if the answer is \"replace.\" Pay the fee to someone with no stake in it."
    },
    {
      "q": "Should I tell the second company what the first one said?",
      "a": "Not at first. Describe symptoms only — what it does, what it doesn't do, what noise it makes, what the panel shows — and ask them to diagnose and put the failed part in writing. Naming a cracked heat exchanger or quoting a number anchors them to it. Once they've written their own diagnosis, show them the first one and ask whether they agree."
    },
    {
      "q": "They quoted over $2,000 in labor to swap a water heater. Is that real?",
      "a": "That is outside the range for the whole labor portion of the job. Fixr puts installation labor on a 50-gallon tank at $180 to $1,250 — 20 to 50% of a total that typically lands at $900 to $2,500, most commonly $1,800, for two to four hours of work. Genuine complications exist: a tight attic, a stairwell, a code-required expansion tank or new venting. Ask which one applies and get it on its own line."
    },
    {
      "q": "The financing paperwork is already on the table. Why does that bother you?",
      "a": "Because it's a closing tool, not a service. Same-day financing turns a four-figure decision into a monthly number and quietly moves the conversation from \"is this diagnosis correct\" to \"can you afford the payment.\" Those are different questions, and only the first one matters tonight. Any financing worth having is still available tomorrow, and a bank or credit union rate almost always beats the tablet in your basement."
