Free HVAC Estimate Template
Made for HVAC contractors estimating system replacements, new installs, and repair work. Itemize the equipment, labor, ductwork, and permits separately so homeowners understand the number — and stop shopping your bid against a bare equipment price.
Use it as an AC installation estimate, a furnace replacement quote, or a heat pump proposal, then export a clean PDF or keep working in Word or Excel.

What to Include in a HVAC Estimate
System size and efficiency rating
Tonnage and SEER2 (or AFUE for furnaces, HSPF2 for heat pumps) are the spec — a "3-ton, 15.2 SEER2 condenser with matching coil" is a real proposal, "new AC" is not. Sizing should come from a Manual J load calculation, not a rule of thumb, and saying so on the estimate separates you from the guys who size by square footage alone.
Equipment vs. labor, split out
Homeowners will Google the unit price, so get ahead of it: list equipment, then labor as its own line. When they see the condenser costs $3,200 and installation is $2,800, the bid makes sense. Bury it all in one number and a competitor's cheaper builder-grade bid looks identical to yours.
Brand, model numbers, and tier
Write the actual model numbers for the condenser, air handler or furnace, and coil. Trane, Carrier, and Lennox sit at the premium tier; Goodman, Rheem, and Amana deliver value tiers at meaningfully lower cost. Model numbers let the client verify AHRI matching and stop a bait-and-switch accusation before it starts.
Permits, inspection, and code items
Mechanical permits run $100-$500 in most jurisdictions and replacements often trigger code upgrades — a new disconnect, pad, float switch, or surge protection. Line-item them. An unpermitted install can void the manufacturer's warranty and blow up a future home sale, so showing the permit is a selling point.
Ductwork, electrical, and lineset scope
State what happens to the existing infrastructure: reuse, flush, or replace the lineset; any duct modifications, sealing, or new returns; breaker or wiring changes. Duct problems are the top source of change orders on replacements, so define this boundary in writing.
Warranty, labor coverage, and rebates
Separate the manufacturer's parts warranty (typically 10 years, registration required) from your labor warranty (commonly 1-2 years, longer on premium installs). Note applicable utility rebates and the federal 25C tax credit — up to $600 for qualifying ACs and $2,000 for heat pumps — since incentives frequently close the deal on higher-efficiency equipment.

What HVAC work costs in 2025-2026
A full central AC replacement in the US currently lands between $6,000 and $13,000 installed, with the national average around $8,000-$9,000. Complete system swaps — condenser, furnace or air handler, and coil — run $10,000 to $18,000. Per ton, installed cost works out to roughly $2,500-$4,500 depending on brand tier and access; most homes need 2 to 5 tons, at about one ton per 500-700 square feet in a properly insulated house, confirmed by a Manual J.
Efficiency tier moves the number more than brand does. Baseline 14.3-15.2 SEER2 equipment is the value play; 16-17 SEER2 two-stage systems add $1,500-$3,000; 18+ SEER2 variable-speed systems add $3,000-$6,000 but qualify for the best rebates. Heat pumps run $7,000-$15,000 installed and are eligible for the $2,000 federal 25C credit, which is worth stating directly on the estimate. Gas furnace replacements alone run $4,000-$8,000 depending on AFUE and venting.
Repair work prices differently: diagnostic fees of $75-$150, labor at $100-$175 per hour, and common repairs like a capacitor ($150-$400), blower motor ($450-$1,800), or refrigerant leak repair with recharge ($500-$1,500+ now that R-410A costs have climbed). Seasonal demand is real — first-heat-wave weeks book out fast, and shoulder-season installs (spring and fall) are where you can offer sharper pricing without losing margin.

Estimate vs. Quote: What's the Difference?
In HVAC the distinction has teeth. A ballpark given over the phone from tonnage and age is an estimate — useful for qualifying the customer, dangerous to treat as a commitment, because you haven't seen the electrical panel, the lineset routing, or the ductwork static pressure. After a site visit and load calculation, issue a firm quote with model numbers and an expiration date of 15-30 days; equipment prices have moved several times a year lately with the refrigerant transition to R-454B and A2L-compatible components. Contractors who skip the site visit and quote off square footage are the ones eating change orders in July.
HVAC Estimate FAQs
Do I really need a Manual J for every replacement?
For any full system replacement, yes — homes get new windows, insulation, and additions, so the old unit's size is not evidence of the right size. An oversized system short-cycles, dehumidifies poorly, and dies early. A Manual J takes under an hour with modern software and is a strong differentiator on the estimate itself.
Should I show equipment cost separately when homeowners can look up wholesale prices?
Yes, and it works in your favor. Hiding the split makes the whole bid feel padded; showing it lets you explain what installation labor actually covers — recovery, brazing, nitrogen purge, evacuation to 500 microns, charging, and commissioning. The value story lives in the labor line.
How do I explain the price gap between SEER2 tiers?
Translate efficiency into dollars: stepping from 14.3 to 16+ SEER2 typically cuts cooling energy use 10-20%, worth $100-$300 a year in hot climates. Then add the rebate math — the 25C credit and utility incentives often cover a third or more of the upgrade cost. Show a good/better/best table so the client chooses a tier instead of choosing a competitor.
What about the R-454B refrigerant transition?
New equipment manufactured from 2025 on uses A2L refrigerants like R-454B instead of R-410A, and prices rose with the change. This matters on your estimate two ways: quotes should expire in 15-30 days because equipment costs keep shifting, and repairs on old R-410A systems are getting expensive enough that repair-vs-replace math now tips toward replacement earlier.
Should permit costs be in the estimate or handled separately?
Put them in the estimate as their own line. It proves you pull permits — many low bidders don't — and an unpermitted install can void manufacturer warranties and surface as a problem during a home sale. If a competitor's bid is $400 lighter, the missing permit line is often the first place to point.
