Offer three matched options for the same 3-ton job: a Good system that does the basics, a Better one that adds efficiency and a longer labour warranty, and a Best one that adds comfort. Price each from your own costs, take every rating from the spec sheets, and use AI only for the plain-English wording.
The format is long established. The risk is what AI adds to it. Left alone, a chat assistant can write savings percentages, "most popular" badges and warranty lengths that nobody checked. Below is one replacement walked end to end: the survey, the cost of each option, the prompts, the draft that comes back, and the lines to strike before a customer sees it.
The job: a 16-year-old 3-ton system in a two-storey house
A four-person heating and cooling firm has surveyed a two-storey house of about 2,100 square feet (an illustrative job). The split air conditioner is rated 3 tons, which is 36,000 BTU an hour because one ton of cooling is 12,000 BTU an hour. It is 16 years old and the indoor coil is leaking. The gas furnace is sound and stays. The customer's priorities, written down at the survey, are a quiet outdoor unit (a bedroom window sits above it), sensible running costs, and not paying for extras they do not need. Those three priorities are what the options will be built around.
SURVEY NOTES, job 0417
Replace outdoor unit and indoor coil; keep existing gas furnace.
Existing: 3-ton single-stage, 16 years old, leaking coil.
House: two storeys, about 2,100 sq ft, ducts in attic, fair
condition, no obvious leaks at joints.
Customer priorities: quiet outdoor unit (bedroom window above it),
fair running cost, not paying for extras they do not need.
Pad: concrete, cracked at one corner; replace with composite pad.
Permit needed. Haul away old unit.What actually separates Good, Better and Best
Customers get confused when options differ in ten ways. Keep it to the few differences they can feel or read on a certificate. Efficiency is the certified rating for the exact pairing of outdoor unit and indoor coil (SEER2 on most split systems sold by the ton), and a higher figure means less electricity for the same cooling under the manufacturer's test conditions. Staging is how the compressor runs: single-stage means full output or off, two-stage adds a lower setting for milder days, and variable-speed adjusts across a range. Warranty has two halves: the manufacturer's parts terms, which can depend on registering the equipment, and your own labour cover, which is your decision and should differ between tiers on purpose. Comfort extras are the thermostat, duct sealing and filtration.
| Lever | Good: Essential | Better: Quiet | Best: Steady |
|---|---|---|---|
| Equipment | Single-stage 3-ton unit with matched coil | Two-stage 3-ton unit with matched coil | Variable-speed 3-ton unit with matched coil |
| Example efficiency class | about 14.5 SEER2 | about 16.5 SEER2 | about 18 SEER2 |
| Manufacturer's parts warranty | Copy the term and its conditions from the model sheet | Copy from the model sheet | Copy from the model sheet |
| Our labour warranty | 1 year | 2 years | 5 years |
| How it runs | Full output, then off | Lower setting on mild days | Adjusts in small steps |
| Thermostat | Basic programmable | Smart | Smart |
| Extras | None | None | Duct sealing at accessible joints, media filter cabinet |
The efficiency classes are placeholders. In a real quote they come from the certified rating for the three real matches you sell, never from an assistant's memory. Each tier answers one of the customer's priorities: Essential is for not paying for extras, Quiet is for the bedroom window and the steadier temperature, and Steady is for the customer who wants the best the range offers. If a lever does not map to something the customer said, remove it from the table.

Buy nowCheck the size before you price three versions of it
All three options assume 3 tons because the old system was 3 tons. That is a starting point, not evidence. A like-for-like swap can leave the house with the wrong size if insulation, windows or the layout have changed since the old unit went in. Before the prices are final, size the job the way your firm normally does, with a load calculation or at least a documented room-by-room estimate, and write the result on the survey note. If it says 2.5 tons or 3.5 tons, all three options change and the prices below move with them. AI is poor at this step because it cannot see the house, so use it only to turn your own figures into a tidy line on the quote.
Price each option from its own cost, then check the gaps
Do this in a spreadsheet before AI touches the quote. List the cost of each option line by line, then divide by one minus your target margin. The figures below are illustrative, with labour at a loaded $62 an hour and a 40% target gross margin, so replace them with your own price book.
| Cost line | Good | Better | Best |
|---|---|---|---|
| Outdoor unit and matched indoor coil | $2,350 | $3,350 | $4,000 |
| Line set, pad, disconnect, drain, small parts | $520 | $520 | $560 |
| Thermostat | $45 | $190 | $260 |
| Duct sealing and media filter cabinet | $0 | $0 | $620 |
| Permit, refrigerant handling, haul-away | $310 | $310 | $310 |
| Labour at $62 an hour | 20 h, $1,240 | 22 h, $1,364 | 25 h, $1,550 |
| Callback reserve for the longer labour warranty | $0 | $120 | $240 |
| Total cost | $4,465 | $5,854 | $7,540 |
| Price at 40% margin, rounded to $50 | $7,450 | $9,750 | $12,550 |
| Gross profit | $2,985 | $3,896 | $5,010 |
The Good price comes from $4,465 divided by 0.6, which is $7,441.67, rounded to $7,450. A common slip is to add 40% to cost instead: $4,465 times 1.4 is $6,251, and the margin on that price is only 28.6%. Margin is measured on the price, markup on the cost, and the two give very different numbers. On a quote this size the slip costs about $1,200.
Now look at the gaps. Better is $2,300 above Good, which is 31%. Best is $2,800 above Better, which is 29%. Each gap should be explainable in one sentence the customer could repeat to their partner: "For $2,300 more we get a quieter two-stage unit, a smart thermostat and a two-year labour warranty." If you cannot write that sentence, the gap is either too wide or the options are too alike. Also decide in advance how much discount each option can bear. Ten per cent off Best gives away $1,255 and leaves $3,755 gross profit, a 33.2% margin. Ten per cent off Good gives away $745 and leaves $2,240. The dollars given away grow with the price, so decide whether you discount at all before you are standing in a kitchen. For wider help on estimating, see can AI price a job accurately.
Feed AI the spec sheets, then ask for the customer's words
This is the one place AI is genuinely strong: reading three manufacturer PDFs and pulling out the facts. Upload the three model sheets and ask for an extraction first, not a sales page. Asking for page numbers makes each fact checkable in seconds, and the practice is covered in more depth in getting answers from HVAC manuals and spec sheets with AI.
From the three attached spec sheets, extract for each model: model
numbers of the outdoor unit and indoor coil, certified efficiency
rating, compressor staging, sound rating, and the warranty terms
including every condition. Give the page number for each fact. Write
"not stated" where the sheet does not say. Do not add anything from
memory and do not write any marketing copy yet.An illustrative result for the Quiet model reads: efficiency 16.5 SEER2 (page 2); staging two-stage (page 1); sound rating "not stated"; warranty "10 years parts" (page 4). The check is the warranty line. On page 4 the sheet says the ten years apply only when the unit is registered within a set window, and the AI dropped the condition. Left in the quote, "10 years parts" becomes a promise you cannot keep for a customer who never registers. The condition is real: one major manufacturer's warranty page says units that are not registered, or are registered more than 60 days after installation, fall back to a base parts warranty that in most cases lasts five years. The sound rating shows "not stated", which means you cannot claim the unit is quiet in numbers. Ask the manufacturer's rep for the figure or leave the claim out.
With the facts extracted and corrected, the second prompt asks for the customer's words. Paste the survey notes, the corrected facts and your three prices, then add this.
Write three options for the customer in plain English, named
Essential, Quiet and Steady. For each: one sentence on what it is,
three short bullet benefits tied to the customer's priorities in the
survey notes, the efficiency rating, the labour warranty, and the
price exactly as given. Use only the facts supplied. Do not state any
savings, percentages, lifespans or rankings. Do not call any option
the most popular. Say "see warranty sheet for conditions" where a
parts warranty is mentioned.A first draft can arrive looking like this for the middle option (illustrative).
OPTION 2: QUIET
Our most popular system. A two-stage unit that runs gently most
of the time, so it is quieter and keeps your rooms steadier.
- 16.5 SEER2 rating, saving you up to 25% on cooling bills
- Quietest outdoor unit in its class
- Smart thermostat included
Labour warranty: 2 years, plus 10 years parts
Price: $9,750 installedStrike four things. "Our most popular system" is unsupported. "Saving you up to 25%" appears in none of your sources. "Quietest outdoor unit in its class" is a ranking, and the sheet gave no sound rating. "Plus 10 years parts" lost its registration condition again. What remains, the plain description, the rating, the smart thermostat and the labour warranty, is good. The prompt forbade savings, popularity and rankings and the assistant still added them, which is why the read-through is not optional. If the quote must be sent today, the safe order is to strike first and polish second. Invented numbers turn up in every kind of AI draft, and spotting made-up figures before a proposal goes out covers the checking habit in general.
Claims you can make and claims to strike
Pin this table above the desk of whoever sends quotes. The replacement wording in the right column stays inside what a sheet or your own records can support.
| Draft says | Verdict | Say instead |
|---|---|---|
| Saves up to 25% on bills | Strike. No source, and it depends on the home, usage and tariff | "Higher rated, so it uses less electricity per unit of cooling in the manufacturer's test." |
| Our most popular system | Strike unless your sales records show it | "Our usual recommendation for your priorities, because of the bedroom window." |
| Quietest in its class | Strike. A ranking needs a source | "Rated at [dB] on the manufacturer's sheet, against [dB] for Essential." |
| 10 years parts | Qualify | "10-year parts warranty when registered within [window]; see warranty sheet." |
| Will last 20 years | Strike | "Lifespan depends on maintenance and conditions; here is what the warranty covers." |
| Better humidity control | Only in the manufacturer's own words | Quote the sheet, or leave out. |
You can still compare efficiency honestly, using only arithmetic on the ratings. For the same cooling, electricity use is inversely proportional to the rating. Going from about 14.5 to about 16.5 SEER2 means roughly 12% less electricity in the test (1 minus 14.5 divided by 16.5), and from 14.5 to 18 it is roughly 19%. Those are ratios under test conditions, not dollars. Turning them into dollars needs the customer's electricity price, the hours the system runs and the efficiency of the old unit, so unless you have all three, leave the dollar figure out and offer to estimate from their last 12 months of bills.
Lay the three options out on one page
A typical old quote is one line: "Supply and install 3-ton air conditioner and coil, $8,200." The customer had nothing to compare it with except another firm's single number. The replacement is a one-page table with the same rows in the same order for every option, so the eye compares like with like. This is the customer-facing version, using the corrected wording and the example prices.
| Essential | Quiet | Steady | |
|---|---|---|---|
| What it is | New single-speed system | New two-speed system | New variable-speed system |
| Efficiency rating | 14.5 SEER2 | 16.5 SEER2 | 18.0 SEER2 |
| How it runs | Full power, then off | Gentler setting on mild days | Adjusts in small steps |
| Our labour warranty | 1 year | 2 years | 5 years |
| Manufacturer's parts warranty | See warranty sheet for conditions | See warranty sheet for conditions | See warranty sheet for conditions |
| Thermostat | Basic programmable | Smart | Smart |
| Extras | None | None | Duct sealing at accessible joints, media filter cabinet |
| Price, installed | $7,450 | $9,750 | $12,550 |
Below the table put one recommendation sentence tied to what the customer said, a short list of separately priced add-ons, an expiry date for the prices, and one signature line. The expiry is your decision, 30 days for example, but state whatever you will honour. Keep the efficiency row to the certified figure and the "how it runs" row to the plain description of staging. Both are facts you can point at on a sheet.
Walk the customer across the table, price last
Start with their priorities, not the equipment. "You told me the bedroom window matters and you don't want to pay for extras, so I've set out three ways of doing that." Then walk across the table by row, not down by option: efficiency, how it runs, warranty, then price last, so the comparison rows get read before the number does. Finish by recommending one option, saying why in their words, and then stop talking. For this household that might be: "For a quiet outdoor unit and a sensible bill I'd choose Quiet. Essential is a sound system if budget decides it, and Steady is for someone who wants the steadiest temperature and the longest labour cover."
When the customer says "just give me the cheapest", answer plainly. "Essential is a proper, matched system with a new coil and the same installation standard. Here is what it does not have compared with the others." Do not sigh and do not downplay it. If Essential is a sound option, saying so costs you nothing, and if it is not, take it off the page. For help with the survey side, turning survey notes into an air conditioning quote with AI covers the notes this walkthrough starts from.
The follow-up message that goes home with them
After the visit the customer may reread the options at home, perhaps with a partner. A short message with the table attached lets them do that without your help. Ask the assistant to write it from the final quote, then read it for promises.
Write a short, friendly follow-up message to [first name] after
today's visit. Summarise the three options in two sentences each,
using only the attached quote. Repeat the priorities they told me.
Say the prices are valid until [date] and offer to answer questions
by phone. Do not add savings, deadlines or pressure.A sound result (illustrative) looks like this.
Hi [first name], thanks for having me round today. You told me the
bedroom window and running costs mattered and that you did not want
to pay for extras, so I have set out three options in the attached
quote. Essential replaces the system with a new single-speed unit
for $7,450 installed. Quiet adds a two-speed unit, a smart
thermostat and two years of labour cover for $9,750. Steady adds a
variable-speed unit, duct sealing, a media filter cabinet and five
years of labour cover for $12,550. Prices are valid until [date].
Call me if it would help to talk it through. [your name]Check each number against the quote and delete anything the assistant adds on its own initiative. Additions to look for include "book this week to secure this price", which is pressure you did not authorise, and "we have limited installation slots", which may not be true. If the message mentions savings or a recommendation you did not make, take it out before it goes anywhere.
A sign-off list for the three-option page
- Matched parts. Each option names the outdoor unit and indoor coil model numbers, both sheets list the same refrigerant, and the efficiency rating is the certified one for that pair.
- Prices tie to costs. Open the cost spreadsheet beside the quote and compare each figure, including the labour hours.
- Warranty wording. Parts terms are copied from the sheet with their conditions, and your labour terms read the way you will honour them.
- Scope lines. Permit, pad, disconnect, haul-away and refrigerant handling are listed as included, and anything you exclude, such as a panel upgrade or ductwork replacement, is named.
- Expiry and signature. A date after which prices lapse, and a place to accept one option.
- Read-back. Ask the assistant to list every number and claim in the final draft with the source line for each. Anything marked "none" comes out, and a second person reads the page before it is sent.
After ten quotes: what the numbers say
Keep a simple sheet with the quote number, date, option chosen, price, margin, the reason the customer gave and the days to decision. Suppose your first ten replacement quotes end like this (illustrative): three customers pick Essential, five pick Quiet and two pick Steady. Revenue is 3 times $7,450, plus 5 times $9,750, plus 2 times $12,550, which is $96,200. Gross profit is $8,955 plus $19,480 plus $10,020, which is $38,455, a blended margin of 40.0% and an average ticket of $9,620.
Read the pattern, not just the total. If eight of ten pick Essential, the gap to Quiet may be too wide, or the Quiet benefits may be badly explained, or your customers simply value price most. If nobody picks Steady, check whether its extras are worth their cost to you, since the duct sealing and filter cabinet add $620 of cost. Ten quotes is a small sample, so keep logging and review again at thirty. Feed the reasons customers give back into the next survey notes, and the prompt will improve with each job.
Questions about three-option HVAC quotes
Does every HVAC quote need exactly three options?
No. Three is a convention that works because it gives a floor, a ceiling and a middle. If a job has only two sensible choices, such as repair or replace, show two. Never invent an option to make another look better, and never list one you would not be happy to install. Track which options customers pick over your next ten quotes and adjust from there.
Can I label the middle option as the most popular?
Only if your own sales records show it. Otherwise write what is true, such as 'our usual recommendation for a home like yours' followed by the reason, which should be the customer's own stated priority. A badge that an AI draft added because it sounds persuasive is an unsupported claim, and a customer who asks how many people choose it will expose it.
What if the customer wants to mix features from two options?
Offer a short list of separate add-ons, each with a price, and explain that the equipment itself comes as a matched set, because the efficiency rating applies to the certified outdoor and indoor combination. Mixing a top-tier outdoor unit with a basic coil can change the rating and the warranty, so check the manufacturer's matching rules before you agree.
How do I answer a customer who just wants the cheapest price?
Treat the Good option as a real option, not a decoy. State what it includes, what it lacks compared with the others, and the price, without sighing or downplaying it. If it is a sound, correctly sized, matched system with a fair warranty, saying so honestly builds more trust than steering the customer upwards, and it keeps the quote credible.
