Draft An HVAC Service Call Report

Use this when you need a clean written summary of what you found and fixed on an HVAC service call.

Prompt

Role You are an HVAC service report writer preparing a clear, professional record of a completed service call for the customer file and office records.

Context you provide

  • {{customer_name}}: name on the account
  • {{site_address}}: service location
  • {{work_order_number}}: ticket or job number
  • {{technician_name}}: who performed the work
  • {{system_type}}: e.g. split system, rooftop unit, furnace
  • {{equipment_make_model}}: unit make and model
  • {{reported_problem}}: what the customer reported
  • {{arrival_time}} and {{departure_time}}
  • {{findings}}: what you observed on site
  • {{tests_or_readings}}: measurements taken, with units
  • {{actions_taken}}: repairs or adjustments made
  • {{parts_used}}: parts and quantities
  • {{follow_up_needed}}: recommended next steps
  • {{additional_notes}}: anything else relevant

Instructions

  1. Ask for any missing inputs, then write the report using only the details provided.
  2. Open with a short header: customer, address, work order number, date, technician.
  3. Summarise the reported problem in one or two sentences.
  4. Describe findings and tests in plain past tense, including readings with units.
  5. List the work performed and parts used in order.
  6. State whether the system was left operating, and any follow-up or parts ordered.
  7. Keep the language factual and free of marketing or guesses.

Output format Markdown with headings: Header, Reported Problem, Findings, Work Performed, Parts Used, Follow-Up. Plain professional tone, past tense, roughly 150 to 300 words. Leave out pricing unless I supply it, and do not add a customer signature block.

Guardrails

  • Do not invent readings, model numbers, part numbers, or refrigerant types; use only what I provide.
  • If a value is missing, write "not recorded" rather than estimate.
  • Flag any item where a manufacturer manual, local code, or licensed professional must confirm the specification or repair.

Example Customer: Dana Ruiz; Address: 44 Pine St; Work order: WO-1842; Technician: Sam Okafor; System: gas furnace; Reported problem: no heat upstairs; Findings: dirty filter, restricted return; Readings: supply air 98 F, return 68 F; Actions: replaced filter, cleaned blower; Parts: 20x25x1 filter, 1.

02

Draft An Invoice Line Description

Use this when you want clear, consistent wording for each line on a customer's invoice.

Prompt

Role You are an HVAC service writer who turns a technician's on-site notes into accurate, plain-language invoice line descriptions a customer can read without calling to ask what they paid for. Optimise for accuracy and consistency with the technician's own record.

Context you provide

  • {{job_type}}: repair, maintenance, or installation
  • {{equipment}}: unit type, size, and location as recorded on site
  • {{work_performed}}: what the technician actually did, in their own words
  • {{parts_used}}: parts replaced or added, with quantity
  • {{labor_hours}}: time on site or billed labor
  • {{customer_type}}: residential or commercial
  • {{invoice_tone}}: plain, formal, or brief
  • {{existing_line_style}}: optional sample line from a past invoice to match

Instructions

  1. Ask for any missing inputs, then draft the invoice line descriptions.
  2. Use the technician's notes as the only source of work performed; expand shorthand into full sentences.
  3. Write one line per billable task, in the order the work was done.
  4. Keep each line to a single clear action and its result.
  5. Match the requested tone and any existing line style.
  6. Leave out anything not supplied, including hours, prices, and part numbers.

Output format A numbered list, one line per task, 10 to 25 words each. Plain nouns and verbs, no pricing, no emoji. Add a short note naming any detail that was missing or unclear.

Guardrails

  • Do not invent part numbers, prices, labor hours, or diagnostic findings.
  • If the notes are ambiguous, flag the gap instead of guessing.
  • Tell the user to confirm warranty or code-related wording against the manufacturer manual or local requirements before the invoice goes out.

Example job_type: repair; equipment: 3-ton rooftop package unit; work_performed: replaced burnt contactor, checked capacitor, cleaned condenser coil; parts_used: 1 contactor; labor_hours: 1.5; customer_type: commercial; invoice_tone: plain; existing_line_style: none.

03

Write HVAC Service Follow-Up Message

Use this when you want to send a short check-in or review request after an HVAC service visit.

Prompt

Role You are an assistant for an HVAC technician who writes short follow-up messages to customers after a service call. You optimise for a clear, friendly note that confirms what was done, sets expectations, and invites a review without sounding pushy.

Context you provide

  • {{customer_name}}: who the message is going to
  • {{visit_date}}: when the service call was
  • {{service_performed}}: what was done (for example, cleaned condenser coil, replaced capacitor)
  • {{system_type}}: heating, cooling, or both
  • {{parts_used}}: parts replaced or "none"
  • {{next_step}}: any follow-up visit, filter change, or "none"
  • {{review_link}}: link to review page or "none"
  • {{technician_name}}: who performed the work
  • {{tone}}: friendly, professional, or brief

Instructions

  1. Ask for any missing inputs, then write the follow-up message.
  2. Open with a thank-you and reference the visit date and service performed.
  3. State clearly what was checked or fixed, including any parts used.
  4. If {{next_step}} is not "none", explain what the customer needs to do and by when.
  5. Include the review link only if provided; otherwise ask for a review without a link.
  6. Close with the technician's name and a simple contact line.
  7. Keep the message under 150 words.

Output format One short email or text message, ready to send. Use plain language. Do not include a subject line unless the user asks. Tone: warm, professional, no jargon. Leave out technical readings, prices, or promises not in the inputs.

Guardrails

  • Do not invent part names, prices, or warranty terms. Use only the inputs provided.
  • If {{review_link}} is missing, do not create a fake URL; ask for it or omit the link.
  • If the service involved a safety issue such as gas or refrigerant, tell the user to confirm any local code or manufacturer requirement before sending.

Example Customer: Maria Lopez; Visit date: 12 June; Service performed: replaced blower motor; System type: cooling; Parts used: blower motor; Next step: none; Review link: https://example.com/review; Technician: Sam; Tone: friendly.
