    HVAC Companies, Symptom Triage & Instant Repair-or-Replace Quote Tool

    A homeowner answers a short symptom questionnaire and snaps two photos of their HVAC unit. The tool gives them a likely diagnosis, an honest repair-or-replace recommendation, and a ballpark price range in under two minutes, then sends the full triage report straight to the HVAC company as a ready-to-book lead.

    Who you sell it to

    HVAC repair and installation companies, especially independent shops competing against national franchises on speed and trust. Best fits owners already paying $75-$300 per lead on Google or Facebook who lose a chunk of those leads to 'just wanted a ballpark price' shoppers who never book a truck roll. Find them through local HVAC associations, on Google Maps searching 'AC repair' plus your target city, or through HVAC supply house counters where owners already talk shop.

    A good fit books 15+ service calls a month and answers their own phone or has one dispatcher juggling too much.

    If you sell it, here is the money picture:

    The first tile is the value of your client's own jobs, which is the reason they will pay you. The other two tiles are what you charge them.

    What your client's own work is worth
    $150-$4,650 per repair job, $7,000-$20,000 per full system replacement
    Their revenue, not your fee
    Setup fee you charge
    $2,500-$3,500
    One-off, paid to you
    Monthly retainer you charge
    $297-$497
    Recurring, paid to you

    How it works

    A homeowner with a broken AC or furnace opens the company's branded web app instead of calling. It asks plain-English questions about what's happening: is it making a sound (and which kind), is air still blowing, has the thermostat display changed, when did it start. Then it asks for two photos: the metal data tag on the unit (which gives the tool the exact model, age, and refrigerant type) and a general photo of the unit itself, which the tool checks for visible red flags like ice buildup, rust, or obvious damage.

    The tool combines the symptom pattern, the unit's age, and those visual flags into a likely diagnosis with a confidence level, then applies a simple rule: if the estimated repair cost is a large enough share of what a full replacement would cost, and the unit is old enough that a repair is a poor bet, it recommends a replacement quote instead of a repair and explains why in plain language. Either way, the homeowner sees an honest ballpark price range immediately, and the full triage report, including their photos and answers, lands in the company's dashboard as a booked or bookable lead, so the technician already knows what they're likely walking into before they leave the shop.

    What to expect

    This is a lead-quality and speed tool, not a replacement for a technician's eyes. Expect it to correctly bucket the general problem area (electrical/capacitor, refrigerant, ignition, airflow, thermostat, or 'likely needs replacement') most of the time, not to nail the exact part every time. The real win most owners see is fewer no-show diagnostic calls from people who were just price-shopping, because the tool already gave them a real number before they booked, and a shorter average job because the technician arrives with a head start instead of starting cold.

    Expect one to two weeks of tuning the diagnostic questions and price ranges against your own real calls before the recommendations feel right for your market. It will occasionally recommend replacement when a cheap repair would have done, or vice versa. Set that expectation with the client up front: this narrows the guess, it doesn't replace the visit.
