Free HVAC Estimate Template

An HVAC estimate should include your business details and license number, the customer's information, a description of the work (repair, replacement, new installation, or maintenance), equipment details (brand, model, tonnage, SEER rating), labor hours and rate, material costs (ductwork, refrigerant, electrical, thermostats), permit fees, a warranty summary, and a total with an expiration date.

HVAC estimates combine equipment cost, labor, and materials. For replacements, start with the equipment price (wholesale plus your markup, typically 30–50%), add labor hours for removal, installation, and testing, then add materials (line sets, electrical, ductwork modifications, thermostat). For repairs, charge a diagnostic fee plus parts and labor. Always perform a load calculation (Manual J) for new installs so you're sizing the system correctly — an oversized or undersized unit creates callbacks.

Yes — always. List the exact brand, model number, tonnage, SEER/SEER2 rating, and type (single-stage, two-stage, variable speed). Customers comparing multiple bids need to see they're comparing apples to apples. Including specs also protects you: if the customer claims they expected a different unit, the estimate is your documentation.

Measure existing ductwork and note material type (flex, sheet metal, fiberglass), condition, and any modifications needed. For new ductwork, size it based on the Manual D calculation. List ductwork as separate line items: trunk lines, branch runs, registers and grilles, transitions, and sealing/insulation. Ductwork is often 30–40% of a full HVAC install cost, so itemizing it helps customers understand where their money goes.

Yes — most HVAC installations and major repairs require a permit. List the permit fee as a separate line item and note whether it includes the inspection. Being transparent about permit costs builds trust and signals that you're a licensed, code-compliant contractor — which differentiates you from unlicensed competitors who skip permits.

Most HVAC contractors set estimates to expire in 30 days. Equipment pricing from distributors can change quarterly, and manufacturer rebates have fixed windows. For jobs dependent on specific equipment availability, note that pricing is subject to change if the unit is back-ordered or discontinued. During peak season (summer/winter), consider 14–21 days since your schedule fills faster.

Start with a load calculation to size the system correctly. Then itemize: equipment (outdoor unit, indoor unit or air handler, thermostat), installation labor (disconnect old system, set new equipment, connect refrigerant lines, electrical, condensate drain, test and commission), materials (line set, disconnect, pad, drain line, electrical whip), ductwork modifications if needed, permit and inspection fees, and disposal of old equipment. Present options (good/better/best) with different efficiency levels so the customer can choose.

Yes — HVAC replacements are major purchases ($5,000–$15,000+), and offering financing can be the difference between winning and losing a bid. List the cash price and a monthly payment option on the estimate. Most HVAC financing is through third-party lenders (Synchrony, GreenSky, Service Finance). Note financing terms clearly: APR, term length, and whether there's a promotional period.

List three options with increasing equipment quality and efficiency. "Good" is a basic single-stage system that meets code. "Better" is a two-stage or higher-SEER system with a programmable thermostat. "Best" is a variable-speed system with a smart thermostat, zoning, and extended warranty. Show the upfront cost and estimated annual energy savings for each option. Most customers pick the middle option, but having three gives them control and increases average ticket value.

Include both the manufacturer's equipment warranty (typically 5–10 years on parts, with registration required) and your labor warranty (typically 1–2 years). Extended warranties and maintenance plans are great upsells — list them as optional line items on the estimate. Clearly state what voids the warranty (no annual maintenance, unauthorized modifications) so there are no disputes later.
