Is this quote fair?

Most homeowners see two or three quotes in a lifetime. We see them every day. Here's what belongs on a good one, what the work typically costs, and the red flags that mean keep shopping.

01 · What a good quote looks like

A good quote is specific

A quote is a scope of work with prices attached. The test of a good one is simple: could a different contractor pick it up and build the same job? If the answer is no — if it says "install heat pump, $14,000" and little else — you can't compare it to anything, and that's usually the point.

Specific doesn't mean long. It means the equipment is named, the quantities are stated, and the things that go wrong on cheap jobs (sizing, prep, cleanup, permits) are in writing. Everything below is standard for contractors who do this work well; none of it is exotic.

02 · Heat pump quotes

What belongs on a heat pump quote

Line item Why it matters
Equipment brand and model numbers Model numbers let you verify efficiency ratings and rebate eligibility. "High-efficiency condenser" is not a model number.
Heating capacity and the load calculation behind it Sizing should come from a heat load calculation (Manual J or equivalent), not the size of the old furnace or square footage alone.
Number and location of indoor heads or air handlers Placement determines comfort. You should know what's going where before install day.
Electrical work New circuit, disconnect, and any panel work — included, excluded, or priced as an option. Surprise electrical is a classic overage.
Line set, pad, and mounting The refrigerant lines and outdoor mounting are real materials and labor. Good quotes name them.
Condensate handling Where the water goes. Missing condensate planning causes the most avoidable service calls.
Permits and inspection Who pulls the permit. If the answer is "you don't need one," check with your building department.
Commissioning Verifying refrigerant charge and airflow at startup. This is what makes the rated efficiency real.
Warranty terms — equipment and labor separately Equipment warranties are the manufacturer's. Labor warranties are the contractor's. You want both in writing.
Rebates, itemized Which programs, how much, and who files the paperwork — you or them.
03 · Insulation quotes

What belongs on an insulation quote

Line item Why it matters
Areas and square footage "Insulate attic" without square footage can't be compared across quotes.
Existing and target R-values The quote should state what you have and what you'll end up with — for example R-11 to R-49.
Material and method Blown-in cellulose, dense-pack, rigid foam, spray foam — each has different performance and price. The material should be named.
Air sealing scope Air sealing before insulating is standard good practice. If it isn't on the quote, ask why.
Prep and safety work Blocking around heat sources, ventilation baffles, covering can lights, moisture checks. Skipping prep is how cheap jobs stay cheap.
Ventilation A tighter house changes airflow. The quote should address attic ventilation and, for major air sealing, whether mechanical ventilation is needed.
Cleanup and disposal Old insulation removal and disposal, if applicable, priced explicitly.
Rebates, itemized Insulation rebates are generous in many states — the quote should show them and say who files.
04 · The price sanity check

What the work typically costs

Typical installed costs before rebates. Local labor, accessibility, and prep needs move real quotes around inside these ranges — a quote outside them deserves an explanation, not automatic rejection.

Type Low High Notes
Ductless mini-split (single zone) $3,500 $6,000 Most common heat pump upgrade
Multi-zone ductless (3-4 heads) $10,000 $18,000 Whole-home coverage without ductwork
Ducted central heat pump $12,000 $25,000 Replaces furnace + AC; needs ductwork
Attic insulation (blown-in cellulose) $1,500 $3,500 R-49 to R-60 target
Wall insulation (dense-pack cellulose) $3,000 $8,000 Drill-and-fill of wall cavities
Basement / crawlspace (rigid foam) $2,000 $5,000 Rim joist + foundation walls

Rebates change the math after the quote, not on it. Compare contractors on the pre-rebate price and scope, then apply your state's programs to whichever job is actually right. A higher quote that includes air sealing, prep, and commissioning is routinely the better deal than a lower one that includes none of them.

05 · Red flags

When to keep shopping

No model numbers

If the equipment isn't named, you can't check efficiency ratings, rebate eligibility, or whether what shows up matches what you bought.

Sizing without a load calculation

"Your old furnace was 100,000 BTU so we'll match it" is how systems get oversized. Ask what the heating load is and how they got it.

Price-per-house, not price-per-scope

A whole-house number with no areas, quantities, or R-values can't be compared and usually hides thin scope.

Sign-today discounts

A price that expires when the salesperson leaves the driveway is a pressure tactic, not a deal. Real quotes survive a week of thinking.

Vague rebate promises

"We'll take care of the rebates" without naming programs or amounts. Get the programs, the dollar figures, and who files — in writing.

No license, insurance, or permit

Unlicensed work can void rebates, insurance claims, and equipment warranties. Verify the license; confirm who pulls the permit.

06 · FAQ

Quote questions

How many quotes should I get?

Two or three comparable quotes is enough — comparable meaning same scope, stated R-values or model numbers, and itemized rebates. Five vague quotes are worth less than two specific ones.

Is the cheapest quote the best deal?

Only if the scope matches. The classic pattern is a low bid that omits air sealing, prep, electrical, or commissioning — the money comes back as change orders or as a system that underperforms. Compare scope first, then price.

Should the quote show rebates?

Yes. Contractors who work your state regularly know its programs and put them on the quote with dollar figures. It's also a competence signal: a contractor who knows the rebate paperwork usually knows the program's install standards too.

What's a fair price for a heat pump?

A single-zone mini-split typically runs $3,500-$6,000 installed; whole-home multi-zone systems $10,000-$18,000; ducted central systems $12,000-$25,000. Where you land in the range depends on capacity, brand, electrical work, and local labor.
