Anchoring, Decoys, and the HVAC Proposal That Closes

Good, better, best has been the gold standard in HVAC sales for years, and it works fine. The problem is that “fine” leaves money on the table. The 2025 ACCA Contractor of the Future Study, drawn from more than 1,000 contractors, found that the shops presenting four or more options close at 52% while everyone stuck at three or fewer closes at 42%.¹ That is a ten point swing on leads you already paid to generate. The catch is that only about 10% of contractors actually offer four or more, which means the advantage is sitting there unclaimed in almost every market.¹

The number most contractors get wrong

Three options feels complete. There is a cheap one, a middle one, and a nice one, and the customer picks. The data says four is the better number, and the lift is not small. Alongside the ten point jump in close rate, shops offering four or more options see premium and high efficiency equipment climb from 26% to 42% of their mix.¹ The fourth option is not about wearing the customer down. It is about giving a buyer enough room to find the solution that actually fits, which is the same solution first approach that earns premium pricing instead of chasing the lowest bid.

Why three collapses to two

Here is what happens in the living room with three options. The homeowner glances at the most expensive one and crosses it off before you finish the sentence. They assume the top price is there to make the middle look reasonable, so they ignore it. Now your three carefully built tiers are really a two horse race between the cheapest and the middle, and the cheapest one is winning more often than you would like.

Add a fourth tier and the math of the conversation changes. The customer still mentally sets aside the very top, but now the option they settle into is your second from the top, not your second from the bottom. The same instinct that made three collapse downward makes four settle higher. Proposal software makes this easy to build, so a fourth tier costs you a few clicks rather than a longer sales call.

The psychology: anchoring, decoy, and the jam study

Three forces are doing the work, and none of them is pressure. The first is anchoring, the human habit of leaning on the first number you see. Lead with the premium option and every option below it feels like a savings instead of a stretch. The second is the decoy effect, where one option exists mainly to make another look like a bargain by comparison. A well placed high tier that is just a little worse value than the one beside it makes that neighbor look obvious.

The third force is the guardrail. In a well known 2000 study, shoppers offered 6 jam varieties bought at a 30% rate, while shoppers offered 24 varieties bought at only 3%.² Too much choice does not impress people, it freezes them, and a frozen buyer says “let me think about it” and never calls back. That is why this is not an argument for ten options. Four to five hits the sweet spot: enough to let anchoring and the decoy do their quiet work, not so many that the homeowner shuts down.

Naming the tiers

The labels matter as much as the count. Good, better, best is honest but weak, because it quietly tells the customer that the cheapest choice is merely adequate and the rest are upsells. Value based names do better. Tie each tier to an outcome the homeowner already told you they care about, like an energy and payback tier, a quiet comfort tier built around variable speed equipment, and a peace of mind tier built around a long labor warranty and priority service.

Be honest about the floor. The bottom tier can be labeled plainly as the code minimum, the least efficient system you are legally allowed to install. Most buyers do not want to be the person who chose the bare minimum for their own home, and naming it accurately lets them talk themselves upward. Mark one of the middle tiers as your recommendation, since a clear recommendation reduces the fear of choosing wrong. This is the same customer education habit that, done consistently, builds the reviews and reputation that bring in the next lead.

Add a money axis, not just a bigger box

The strongest fourth option often is not a bigger piece of equipment. It is a new way to pay for one. Financing is its own axis of choice, and it moves the needle hard: the same study found that offering financing lifts close rates from 38% to 49%.¹ Independent trade data shows the same pattern, with financed jobs carrying higher close rates and larger average tickets.³ Lead with the monthly payment instead of the total price and a much larger share of customers find a yes they could not reach when they were staring at a five figure number.

Add ons work the same way. An indoor air quality package or a labor warranty opens a fresh dimension of value rather than piling another number onto the same shelf, so the customer is comparing different kinds of good rather than wrestling with one long price list. That is also why the customers who buy up tend to be the ones worth keeping: they bought a solution they believe in, and they refer people like themselves.

Start simple this week. Build a four tier proposal template, label each tier by the outcome it delivers rather than good, better, best, lead with your premium option to set the anchor, and make financing one of the choices on every estimate. None of it asks you to sell harder. It asks you to lay the options out the way buyers actually decide.

This one came out of a conversation on the HVAC Know It All Business Edition Podcast with TJ O’Connor of Farmington Consulting Group, who broke down the Contractor of the Future findings on proposals and close rates.
