Every manufacturer encodes the installation date in the serial number. AI knows the codes. These three prompts let you snap a photo at the showing and get back a plain-English report — age, remaining life, ballpark replacement cost, and talking points — in under a minute.

Copy the prompt for the system you want to check, open ChatGPT or Claude on your phone, attach the photo, and send. The AI generates a formatted PDF report you can save or share with your client.

The inspector still does the inspection. This gives your buyer realistic expectations before they write the offer.

Prompt 1 — HVAC System

Photograph the data plate on the outdoor condenser and, if accessible, the indoor air handler. They may be different ages — check both.

HVAC Prompt
I'm a real estate agent reviewing an HVAC system for a client. Attached is a photo of the data plate. Please provide: 1. Manufacturer and model — read directly from the plate 2. Date of manufacture — decode from the serial number, and tell me how you decoded it (brand-specific conventions vary) plus your confidence level 3. System specs — tonnage/BTU capacity, SEER/SEER2 rating, electrical specs 4. Refrigerant type and status — flag if R-22 (phased out, service is expensive and limited), R-410A (being phased down under the AIM Act), or newer A2L refrigerants like R-454B / R-32 5. Age assessment — current age, typical lifespan for this brand/type, rough remaining useful life 6. Known issues — recalls, class actions, or documented defects for this make/model/era (e.g., bad coil generations, compressor issues) 7. Ballpark replacement cost range if it's near end of life 8. Three plain-English talking points I can share with my client Rules: - If anything on the plate is illegible or can't be decoded with high confidence, say so — don't guess. - Use today's date for age math. - If you'd need to web-search to verify recalls or current refrigerant rules, do that. - Format the output as a clean, professional PDF report. Use a bold title ("HVAC System Report"), a summary box at the top with the three most important flags, then numbered sections with bold headings for each item above. Close the report with a bold "IMPORTANT DISCLAIMER" section in italics: "This report is prepared by [Agent Name], a licensed REALTOR®, as an informational summary based on the equipment data plate provided and publicly available industry data. It is not a substitute for a professional HVAC inspection performed by a licensed contractor with proper diagnostic equipment, and it does not constitute a warranty or guarantee of the equipment's condition, performance, or remaining useful life. Cost estimates are general ranges based on current market data and may vary materially based on local labor, permit, ductwork, and equipment selection factors. Refrigerant pricing and regulatory information were current as of the report date and are subject to ongoing change under the EPA's AIM Act phasedown and related rulemaking. Buyers are strongly encouraged to obtain an independent licensed HVAC contractor's inspection and written estimate prior to removing inspection contingencies."

Prompt 2 — Water Heater

Photograph the data plate and the serial number label. Get as close as the camera will focus — the serial number has to be legible.

Water Heater Prompt
I'm a real estate agent reviewing a water heater for a client. Attached is a photo of the data/rating plate and serial number label. Please provide: 1. Manufacturer and model — read directly from the plate 2. Date of manufacture — decode from the serial number, and tell me how you decoded it (serial conventions vary by brand: Rheem encodes month/year in the first 4 digits, AO Smith uses a rotating letter code, Bradford White uses a letter-number prefix, etc.) plus your confidence level 3. Unit type and specs — tank or tankless, gas or electric, capacity in gallons, first-hour rating if shown 4. Energy efficiency — Energy Factor (EF) or Uniform Energy Factor (UEF) if visible; flag if it's below current standards 5. Age assessment — current age, typical lifespan for this brand/type (tank gas: 8-12 yrs; tank electric: 10-15 yrs; tankless: 15-20 yrs), rough remaining useful life 6. Known issues — any documented recalls, class actions, or failure patterns for this make/model/era (e.g., anode rod corrosion, sediment buildup, faulty pressure relief valves) 7. Ballpark replacement cost range if it's near end of life — include both a like-for-like tank replacement and a tankless upgrade 8. Three plain-English talking points I can share with my client Rules: - If anything on the plate is illegible or can't be decoded with high confidence, say so — don't guess. - Use today's date for age math. - If you'd need to web-search to verify recalls, do that. - Format the output as a clean, professional PDF report. Use a bold title ("Water Heater Report"), a summary box at the top with the three most important flags, then numbered sections with bold headings for each item above. Close the report with a bold "IMPORTANT DISCLAIMER" section in italics: "This report is prepared by [Agent Name], a licensed REALTOR®, as an informational summary based on the equipment data plate provided and publicly available industry data.

Prompt 3 — Electrical Panel

Photograph the panel door (closed, showing the manufacturer label), the breaker layout (open), and any label inside the door. Three photos is better than one.

Electrical Panel Prompt
I'm a real estate agent reviewing an electrical panel for a client. Attached is a photo of the panel door, the breaker layout, and the manufacturer label. Please provide: 1. Manufacturer and model — read directly from the label. Flag immediately if this is a Zinsco (also sold as Sylvania), Federal Pacific Electric (FPE/Stab-Lok), or Pushmatic panel — these have serious documented safety issues described below. 2. Zinsco/Sylvania flag — if identified: breakers in these panels are known to overheat, fail to trip under overload, and weld themselves to the bus bar, creating fire risk. These panels are often uninsurable and are considered a material defect by most inspectors. Replacement is typically $2,500-$5,000. 3. Federal Pacific Electric (FPE/Stab-Lok) flag — if identified: CPSC studies and independent testing have documented that Stab-Lok breakers fail to trip at higher-than-rated rates. This is a known fire hazard. Many insurers will not write a policy on a home with an FPE panel. Replacement is typically $2,000-$4,500. 4. Service capacity — main breaker amperage (60A, 100A, 150A, 200A) and whether that's adequate for modern loads (200A is the current standard for most homes; 60-100A panels are undersized for homes with EV chargers, heat pumps, or high appliance loads) 5. Approximate age — if a manufacture date is visible or can be inferred from the panel model; note that panels often outlast the original install by decades and may have had breakers added or swapped 6. Red flags visible in the photo — double-tapped breakers (two wires on one breaker terminal), tandem/piggyback breakers in a non-tandem-rated panel, burn marks, corrosion, mixed-brand breakers in a panel that requires brand-matched breakers, open knockouts 7. Insurance and financing implications — flag any issues that commonly cause homeowner's insurance denial or loan underwriting problems 8. Ballpark cost range — for a full panel replacement if warranted 9. Three plain-English talking points I can share with my client Rules: - If the panel manufacturer is unclear, describe what you can see and say so — don't guess the brand. - Flag Zinsco and FPE as priority items even if everything else looks fine. - Use today's date for age math. - If you'd need to web-search to verify recalls or current code implications, do that. - Format the output as a clean, professional PDF report. Use a bold title ("Electrical Panel Report"), a summary box at the top with the three most important flags (lead with any Zinsco/FPE identification immediately), then numbered sections with bold headings for each item above. Close the report with a bold "IMPORTANT DISCLAIMER" section in italics: "This report is prepared by [Agent Name], a licensed REALTOR®, as an informational summary based on the panel label, breaker layout, and publicly available industry data. It is not a substitute for a professional electrical inspection performed by a licensed electrician, and it does not constitute a warranty or guarantee of the panel's condition, safety, or compliance with current code. Identification of a Zinsco, Sylvania, or Federal Pacific Electric panel does not confirm the presence or absence of a defect — a licensed electrician must evaluate the panel in person before any conclusions are drawn. Cost estimates are general ranges and may vary materially based on local labor, permit, and equipment factors. Buyers are strongly encouraged to obtain an independent licensed electrician's inspection and written estimate prior to removing inspection contingencies." Designed to be printed or saved as a PDF.

How to Use These at a Showing

  1. Snap the photo.Get as close as the camera will focus. The serial number has to be legible. For HVAC, grab both the outdoor condenser and the indoor air handler — they can be different ages. For electrical panels, photograph the door (closed), the breaker layout (open), and any label inside.
  2. Open ChatGPT or Claude.Both work. You need a version with photo/vision support — ChatGPT Plus, GPT-4o, or Claude on claude.ai. Attach the photo first, then paste the prompt.
  3. Share the report.The AI formats the output as a PDF-ready report with a summary box and talking points. Screenshot it or copy the text to share with your buyer before they write the offer.

What These Give You

A ballpark — not an inspection. These prompts decode the serial number, pull publicly available lifespan data, and flag known issues for the make and model. The inspector confirms everything in writing. You prepared your buyer before the offer.

The electrical panel prompt is the highest-stakes of the three. If it flags a Zinsco or Federal Pacific panel, that's a conversation to have before the offer is written — not after the inspection report lands on a Tuesday with a Wednesday deadline.
