Free HVAC Invoice Template

HVAC invoices have unique line items most invoice templates don't handle: refrigerant, EPA-608 disposal, ductwork, permits, and equipment startup. This template covers them, plus the warranty registration and rebate-paperwork notes that protect both you and the customer.

How an HVAC invoice should be structured

HVAC invoices have unique line items most generic invoice templates miss: refrigerant by type and pounds, EPA Section 608 disposal of old refrigerant, ductwork modifications, equipment startup and commissioning, and warranty registration. Without these documented, you risk EPA compliance issues and the customer loses their manufacturer warranty.

The seven sections of a complete HVAC invoice

1. Equipment

List the exact equipment installed: brand, model number, serial number, capacity (BTU/tonnage), efficiency rating (SEER for cooling, AFUE for heating), and any specialty features (variable-speed, two-stage, communicating thermostat compatibility). Format:

Carrier 24ANB736A003 outdoor condenser, 3 ton, 16 SEER
Serial: 1234A56789
Carrier FB4CNF036 indoor coil, 3 ton
Serial: 5678B12345

This level of detail protects you and the customer in three ways: manufacturer warranty registration requires it, utility rebates require it, and IRA Section 25C tax credits (30% of equipment cost, up to $2,000 for heat pumps and $600 for AC) require manufacturer certification statements that match the model installed.

2. Refrigerant

Document refrigerant on every install or service involving a refrigerant circuit:

  • Type (R-410A, R-32, R-454B for newer systems — R-22 phase-out is ongoing)
  • Pounds added or removed
  • For old equipment removal: EPA Section 608 recovery and disposal documentation

Required line on equipment-removal invoices: “EPA Section 608 refrigerant recovery and disposal: [X] pounds of [refrigerant type] recovered per federal regulations.” This documents your compliance with 40 CFR 82, which mandates certified technicians recover refrigerant before equipment disposal.

3. Ductwork

For installs involving new ductwork or modifications to existing: linear feet of new duct (sized appropriately), linear feet of duct modification (re-routing, resizing), supply and return additions, damper modifications, and insulation. New construction installs will have significant ductwork; equipment swaps may have only minor modifications.

4. Electrical

Line voltage runs to outdoor unit, low-voltage thermostat wiring, disconnect installation, breaker upgrades if needed, and any service panel work. If you’re not licensed for electrical work in your jurisdiction, sub it out and bill it as a separate line — most HVAC contractors handle the equipment-side electrical (whip from disconnect to unit, thermostat wire) but use a licensed electrician for any panel work.

5. Labor

Two phases: Installation (set equipment, connect refrigerant lines, run electrical, install thermostat, ductwork connections) and Commissioning(vacuum lines, charge with refrigerant per manufacturer specs, verify operation across full range, set thermostat parameters, customer training). Bill commissioning separately — it’s skilled work that warranty validity depends on, and it justifies the higher rate.

6. Permits and inspection fees

Pass through to the customer at cost (no markup on permits — most states explicitly prohibit it). List permit number, jurisdiction, and inspection-pass date if available. This is critical documentation for resale and insurance.

7. Manufacturer warranty + rebate processing

If you’ve registered the manufacturer warranty (most major brands void or shorten the warranty if not registered within 60–90 days), document on the invoice: “Manufacturer warranty registered [date]. Confirmation: [number]. Customer warranty certificate provided.”

For utility rebates and tax credits, document the qualifying equipment and any paperwork you’ve provided:

  • “Equipment qualifies for [utility name] rebate of $X. Application form provided to customer.”
  • “Equipment qualifies for IRA Section 25C federal tax credit (30% of installed cost, up to $2,000 for heat pumps; $600 for high-efficiency central AC). Manufacturer Certification Statement provided to customer.”

Most homeowners don’t know about these incentives. Handling the paperwork makes you the contractor they refer to friends.

Service call vs project pricing

Two-part billing for service calls (no-cool, no-heat dispatches):

Service call dispatch: $89
Diagnostic time: 1 hour @ $135/hr = $135
Capacitor (Genteq 35/5 µF): $35
Labor (replace capacitor, verify operation): 0.5 hr @ $135/hr = $68
Subtotal: $327
Tax: $20
Total: $347

For full equipment installs and replacements, no service-call line — single project price covering all the categories above.

Frequently Asked Questions

What line items should an HVAC invoice include?

Standard categories: equipment (by model number with SEER/AFUE rating), refrigerant (type and pounds, with EPA-608 disposal of old refrigerant), ductwork (linear feet of new + modifications), electrical (line voltage runs, disconnects, breakers), labor (install hours + commissioning hours), permits and inspection fees, and any rebate-paperwork processing if you're handling that for the customer. Group equipment, materials, labor, and fees as separate sections.

Should the model number be on the invoice?

Always. List the exact equipment installed: brand, model number, serial number, SEER/AFUE rating, BTU/tonnage. This is critical for: (1) warranty registration with the manufacturer, (2) rebate processing (utility rebates and tax credits require model documentation), (3) future service calls (next tech needs to know what's installed), (4) home-resale documentation. Without model numbers, the customer can't claim the IRA tax credit or utility rebate.

Should I include EPA-608 refrigerant disposal language?

Yes if you're removing old equipment with refrigerant. Add a line item: 'EPA Section 608 refrigerant recovery and disposal: [pounds] of [refrigerant type] recovered per federal regulations.' This documents your compliance with 40 CFR 82, which requires certified technicians to recover refrigerant. The customer may not understand why this is on the invoice, but it's required by law and protects you in audits.

How do I handle warranty registration on the invoice?

Most major manufacturers (Carrier, Trane, Lennox, Rheem) require warranty registration within 60–90 days of install for the full warranty term to apply (typically 10 years parts vs 5 years if not registered). Best practice: include a line on the invoice stating 'Manufacturer warranty registered on [date]. Registration confirmation #[number].' This proves you handled it. Also give the customer a copy of the registration confirmation; if you fold the warranty into the install service, document it.

How should I bill for equipment vs labor?

Two approaches. Itemized: equipment at cost + markup (typically 15–30%), labor at hourly rate or fixed install price. Bundled: 'Equipment installed: $X' as one line, no breakdown. Itemized is more transparent and trusted; bundled is faster and protects your margin from being shopped. For service work, itemize. For full equipment swaps, either works. State your terminology clearly.

What about utility rebates and tax credits?

If the equipment qualifies for utility rebates (most utilities offer $200–$1,500 for high-efficiency installs) or federal tax credits (IRA Section 25C: 30% of cost up to $2,000 for heat pumps, $1,200 for AC), document it on the invoice. Add a section: 'Equipment qualifies for [utility name] rebate of $X — application form attached.' AND 'Equipment qualifies for IRA Section 25C federal tax credit — Manufacturer Certification Statement attached.' Many homeowners don't know about these and you become a hero by handling the paperwork.
