Free HVAC Invoice Template

An HVAC invoice has to explain a repair the customer never sees: what failed inside the condenser or furnace, which parts you replaced, how much refrigerant went in and what is still under warranty. Good detail here settles questions about the bill and gives the customer a service record for the equipment.

This HVAC invoice template is loaded in the editor below with a summer air conditioning repair: a diagnostic fee, a run capacitor and contactor, refrigerant billed by the pound, labor hours, and the equipment model and serial number in the invoice header. Replace it with your company and the call you just ran, then download a PDF.

What to include on an HVAC invoice

Next to your company details, the customer's details, an invoice number and dates, heating and cooling invoices need a few specifics.

Equipment model and serial
Record the make, model and serial number of the unit you worked on. Manufacturers ask for the serial on warranty claims, and it lets you or the next technician look up the service history. Add them as custom fields in the invoice details.
Diagnostic or service call fee
List the diagnostic fee on its own line and say whether it is credited toward the repair. A clear policy printed on the invoice prevents most arguments about paying “just to look”.
Parts with specifications
Name each part with its rating, such as “Run capacitor, 45/5 MFD” or “Contactor, 30 A, 2-pole”. It shows the customer exactly what was replaced and helps the next repair go faster.
Refrigerant by the pound
Bill refrigerant by type and quantity, for example “R-410A (lb)” × 3, with the price per pound. If you found and repaired a leak, say so; topping up without a repair is worth noting too.
Labor hours and rates
Show labor as hours × rate, or as a flat-rate task price if that is how you quoted. Overtime and after-hours calls go on their own line with the higher rate.
Warranty terms
Separate the manufacturer's parts warranty from your own labor warranty, for example “Parts: per manufacturer. Labor: 90 days”. Customers often confuse the two, and the invoice is the place to spell it out. Mention any registration the manufacturer requires for the full warranty.

Example: an AC repair with refrigerant

A diagnostic fee, two replacement parts, three pounds of refrigerant and an hour and a half of labor. Sales tax applies to parts and refrigerant only in this example.

Description Qty Rate Amount
Diagnostic fee 1 $89.00 $89.00
Run capacitor, 45/5 MFD 1 $65.00 $65.00
Contactor, 30 A 1 $85.00 $85.00
R-410A refrigerant (lb) 3 $95.00 $285.00
Labor (hours) 1.5 $120.00 $180.00
Subtotal $704.00
Sales tax (8% of $435.00 in parts) $34.80
Total due $738.80

Tax treatment of HVAC labor, parts and refrigerant differs by state and country. When only part of the bill is taxable, enter the tax you calculated as a fixed amount on the tax line.

Repairs, replacements and maintenance agreements

Repair calls are invoiced on the spot, usually from a flat-rate price book or as time and materials. Full system replacements are different: they are large enough that customers compare several bids, so write the proposal first in the quotation generator, including the equipment model numbers, SEER2 or AFUE ratings and what the install includes. When the customer accepts, convert the quote to an invoice.

Maintenance agreements bring recurring work: a spring cooling tune-up and a fall heating tune-up, often with a discount on repairs. Invoice the agreement as one line with the period it covers, and when you apply the member discount to a repair, use the discount line so the saving is visible. A tune-up invoice is also a good place to list what you checked (filters, coils, electrical connections, drain line) and anything you recommend fixing before the next season.

  • For a replacement, list the equipment, the install labor and permits on separate lines.
  • For tune-ups, put the checklist items you performed in the details line.
  • Note filter sizes and any recommended repairs the customer declined.
  • Use the equipment's serial number as a custom field on every visit.

Refrigerant handling and records

In the United States, technicians who work on refrigerant circuits must hold EPA Section 608 certification, and rules on refrigerant recovery, leak repair and record keeping apply to many systems. Other countries have their own rules. Your invoice is not a compliance record by itself, but listing the refrigerant type and pounds added or recovered makes your own records much easier to keep.

Refrigerant prices have moved a lot as older types are phased down, so customers are more likely to question that line than any other. A clear per-pound price, the refrigerant type and a note about the leak you found or repaired answer most questions before they are asked.

  • Write the refrigerant type on its own line, never just “Freon”.
  • Put pounds added (or recovered) in the quantity column.
  • Note whether a leak was found, repaired, or recommended for repair.
  • Keep your certification number handy if customers or clients ask for it.

Payment terms for HVAC contractors

Residential repair calls are normally paid when the technician finishes, so use “Due on receipt” and list the payment methods you accept. Being able to take a card or payment link on site shortens the time from repair to payment.

For system replacements, a deposit when the equipment is ordered and the balance at completion is a common structure. Enter the deposit in the Amount paid field on the final invoice so the customer sees the balance due. Deposit limits for home improvement work vary by state, so check local rules.

Commercial customers and property managers usually pay on Net 30 and often need a PO or work order number. Put it in the invoice header and send the invoice when the call is closed, not at the end of the month. For maintenance agreements billed once a year, send the invoice a few weeks before the renewal date so the customer has time to approve it before the first seasonal visit.

HVAC invoice FAQ

Diagnostics, parts, refrigerant and warranties.

What should an HVAC invoice include?

Your company and license details, the customer's details, invoice number and dates, the equipment model and serial, the diagnostic fee, each part with its specification, refrigerant type and pounds, labor, tax if it applies, the total and warranty terms.

How do I bill refrigerant on an invoice?

Add a line with the refrigerant type and “(lb)”, put the pounds in the quantity column and the price per pound as the rate. The amount is calculated for you.

Where do I put the unit's model and serial number?

Add custom fields in the invoice details, such as “Equipment” and “Serial #”. They print in the invoice header. The HVAC template already has both set up.

Should the diagnostic fee be credited toward the repair?

That is your policy to set. If you credit it, list the diagnostic fee and then apply a discount of the same amount, or leave it off and note that it was waived.

Can I quote a system replacement first?

Yes. Write the proposal in the quotation generator, then use Convert to invoice when the customer accepts. Every line and the customer details come across.
