• Free. The files come by email.
• Deepsel is our product: free estimate, invoice and scheduling software for contractors (scheduling, quotes, invoicing, card payments, service plans). The section before the FAQ says where it fits.
• Not legal or tax advice. The license, tax and deposit rules quoted here were read in October 2026; check your state before you rely on them.

This HVAC invoice template is a one-page service invoice laid out the way HVAC shops bill: a diagnostic fee and its credit line, a flat-rate repair or labor hours, parts with part numbers, refrigerant by type and pound, the member discount, sales tax on the lines your state taxes, and a block for the readings the technician took. Page 2 is a filled-in HVAC invoice example from a capacitor call in Texas. Page 3 says how to fill it in, with the state rules that change it.

Get it five ways: make your own copy in Google Sheets or download the Excel version (.xlsx), where the line totals, member discount, tax and balance calculate themselves; or copy the Google Doc, download the Word version (.docx), or print the PDF for the clipboard. Pick a format, enter your email and I'll send the links. Plumbers and electricians get the same layout in the plumbing invoice template and the electrician invoice template.

I downloaded the free HVAC invoice templates that rank before building this one. Invoice Simple's heating and cooling Word file is a general invoice with a Ship To block and a Shipping/Handling line, and nowhere to put a model, a serial or a license number.¹ The first of Wave's HVAC Word files is six item lines and a note box.² Jobber's page has the best advice of the bunch (diagnostic fee on its own line, refrigerant by type, pounds and price per pound, make, model and serial for every unit), and its generator hands you a PDF.³ Staxen's is built for a changeout, with AHRI and SEER2 fields.⁴ None of the ones I read has a place for readings. That's the part of an HVAC invoice the homeowner, the next technician and a warranty claim all come back to.

What should an HVAC invoice include?

An HVAC invoice should include your company name, address, phone and license number, the invoice number and dates, the bill-to and service addresses, the make, model and serial of each unit you worked on, what the customer reported and what you found, the readings you took, line items for the diagnostic, the repair or labor, parts, refrigerant (type and pounds), filters and permits, the member discount, sales tax, deposits and the balance due, then payment terms, the warranty and the customer's approval.

Your license number, and three states that spell it out

Texas is the strictest. Every air conditioning job gets an invoice, the company name, address and phone go on it, and "the affiliated licensee's number must appear on all proposals and invoices." The same subsection makes you print "Regulated by The Texas Department of Licensing and Regulation" with TDLR's address, phone numbers and website.⁵ The template carries that line at the foot of page 1; delete it outside Texas.

Florida's contractor statute covers Class A and B air-conditioning contractors and requires the certification or registration number on "each offer of services, business proposal, bid, contract, or advertisement."⁶ California wants the license number on all construction contracts, subcontracts, calls for bid and advertising.⁷ Neither names the invoice. I'd print it anyway, because on a service call the signed invoice is often the only written agreement there is.

EPA 608 and the refrigerant lines

Anyone who maintains, services, repairs or disposes of equipment that could release refrigerant needs Section 608 certification, and residential split systems fall under Type II.⁸ Only certified technicians can buy refrigerant.⁹ No federal rule puts the cert number on a homeowner's invoice. The template has a spot for it anyway, next to the technician's name.

Two EPA rules do touch the paperwork. A technician servicing equipment with 50 pounds or more of ozone-depleting refrigerant has to give the owner an invoice showing the amount added. And a technician disposing of a system that holds 5 to 50 pounds, which is most residential splits, has to keep records of the location and date of recovery, the refrigerant type and the amounts.¹⁰ That's why the readings block has Refrigerant added and Recovered: on a changeout, the Recovered line is the job's share of that record.

Make, model and serial, from the data plate

Copy them from the data plate, not the box. On an install this line carries real money. Trane's base limited warranty starts when start-up is "recorded on the installer's invoice, which includes all model and serial numbers of the installed Product(s)." Leave it off and the warranty clock starts 60 days after the factory manufacture date instead.¹¹

How HVAC shops structure line items

Itemizing is the argument that never ends on r/HVAC. A Pennsylvania owner asked what others charge for an hour and a 45/5 capacitor. He charges $295, doesn't itemize, and has customers "questioning the cost thinking it's excessive." One reply: "We don't itemize because every time someone tries it, they get berated by the customer." Another tech priced the same call at $320 and showed the math: $230 of labor at $115 an hour, a $40 truck charge and $50 for the capacitor.¹²

The homeowner's side, from r/hvacadvice in January: an invoice that read "warranty blower motor - $1100" for a part the company admitted was free, explained on the phone as "a flat rate charge for that work."¹³

The template takes the middle road. Flat-rate shops keep one price per task, and the customer still sees what went into the system: each part on its own line with your part number and your selling price, refrigerant by the pound, and the readings that justified the work. Your cost and your markup never appear. Pick flat rate or time and materials per job and use the same method on the quote, which is Jobber's advice too.³ Permits and old-equipment disposal go at cost, each on its own line.

The diagnostic fee and its credit

Most companies charge $75 to $200 to diagnose, and the fee is often waived or applied to the repair when the customer goes ahead.¹⁴ Put it on its own line either way. Then add a Credit line for the same amount, as a negative, when you apply it. The customer sees that the visit had a price and that you gave it back, and a member whose fee is waived gets the same two lines.

Refrigerant by the pound

Bill refrigerant by type and pound, never as "recharge system." Trane puts R-410A at $40 to $90 a pound installed and R-22 at $100 to $250, and a system holds 2 to 4 pounds per ton.¹⁵ HomeGuide's range for R-410A is $50 to $100 a pound installed, against $4 to $8 wholesale.¹⁶ One tech on r/hvacadvice explained his own number this July: about $9 a pound at the supply house, "about $120 / pound" delivered to a new residential customer, $100 commercial, and $20 a pound less for customers on a service contract.¹⁷ Whatever you charge, a line that says "R-410A, 2 lb at $85" can be checked. A low charge also means a leak, so the example puts the leak search in Recommended with its own quote.

The member discount on its own line

If the customer is on a maintenance agreement, show the discount as a line. The Disc column marks which lines it applies to (the repair, parts and refrigerant in the example, not the diagnostic or the filter), and the member watches the plan pay for itself on every visit. The HVAC maintenance agreement template sets the rate this line uses.

The readings that belong on the invoice

On a cooling call the block takes six numbers: outdoor temperature, return and supply temperatures (the split), total external static pressure, the capacitor's rated and measured microfarads, compressor amps against the nameplate RLA, and superheat or subcooling against the target. A heating call adds temperature rise, CO in the flue and gas pressure. Refrigerant added and recovered close it out.

Each number settles a question before it's asked. A capacitor is the part most often sold as "weak," and most allow a 6 percent tolerance, so a 45 µF can reading below about 42.3 is out of spec.¹⁸ With 39.8 written next to the 45, nobody needs a second opinion. Static pressure over 0.5 inches of water column is worth a note, and 0.8 is where trouble starts on most newer residential systems.¹⁹ The target ranges for the rest are in the HVAC maintenance checklist, the sheet those readings come from on a maintenance visit.

Homeowners are being told to ask for these: my guide for owners on what to ask the HVAC technician calls a visit that ends with "everything looks good" and no numbers a sales call. Skipped a reading? Write why. "Too cold for a charge check, 48 °F" is an honest invoice.

HVAC invoice example

Here's page 2 of the template: a July service call in Austin. The outdoor fan had stopped, the run capacitor read 39.8/4.9 µF against a 45/5 rating, the contactor was pitted, and the system was 2 pounds low by subcooling. The customer is on a plan with 15 percent off repairs, and Texas taxes the parts but not residential repair labor. Made-up company, customer and prices.

The math, so you can check the spreadsheet. The lines marked Disc come to $500, so the discount is $75.00. The taxed lines come to $347; take 15 percent off the $325 of them that are also discounted and $298.25 is taxable, which at 8.25 percent is $24.61. Above the line items, the example's Recommended row quotes a leak search at $249 and flags the 0.62 static for a return duct check.

Payment terms and late fees

Residential service is due on receipt in most shops, and the template defaults to it. Property managers and commercial accounts usually get net 15 or net 30 and want their PO number on the invoice, which is why the header has a Job / PO field.

A late fee needs two things: the customer knew before the work, and the amount stays inside what your state allows. Nolo says to charge one only if the client was on notice at the outset; at 10 percent a year or less you probably won't run afoul of state statutes, and above that a court can test the fee against your actual losses.²⁰ FreshBooks calls 1.5 percent a month the common approach for small service businesses.²¹ Print the same wording on your quote or work order.

Deposits and progress billing on replacements

A repair gets one invoice. A system replacement usually gets three: a deposit when the customer signs, a progress payment when the equipment lands, and a final invoice after start-up that shows both as payments received. The line items for a replacement come from the material list the crew loaded.

Check your state first. In California, air conditioning and heating equipment count as home improvement goods,²² a home improvement deposit can't exceed $1,000 or 10 percent of the contract price, whichever is less, and apart from that deposit you can't request or accept payment that exceeds the value of the work performed or material delivered.²³ California's lighter rules for small service and repair contracts apply only when the job is $750 or less, the customer called you, and no payment is due until the work is done.²⁴ On the final invoice, enter everything received under Deposit / paid.

Sales tax on HVAC labor and materials

It depends on the state and on how you split the invoice, which is why every line has its own Tax box. Three big states give three different answers:

• Texas: labor to repair residential real property isn't taxable. Bill the materials separately and you collect tax on them; bill one lump sum and you pay tax on materials when you buy them and charge the customer none. Repair of nonresidential property is taxable in full.²⁵
• New York: all charges for materials and labor on a repair, maintenance or installation job are taxable, markups included.²⁶ A capital improvement isn't, and the customer gives you Form ST-124 to show it.²⁷
• California: contractors are consumers of the materials they install and retailers of the fixtures, and the state names air conditioning units and furnaces as fixtures, so tax is due on their selling price. In the state's contractor guide, a separately stated installation fee counts as nontaxable labor.²⁸

Anywhere else, read your revenue department's contractor guide first. The spreadsheet taxes only the lines marked Y, after the member discount.

Invoice numbering

Use the year and a running number: 2026-0001, 2026-0002. Never reuse a number and never delete one. A voided invoice keeps its number with VOID across it, so the sequence has no gaps when your accountant reads it. Put the job number next to it (the header has a field) and the quote, the work order and the invoice all point at each other.

How to fill in the template

1. Fill the header once: company, license number, phone, and your logo above the title in the Google Doc. Keep the TDLR line only in Texas.
2. Per job: invoice number, dates, addresses, and the equipment from the data plate.
3. Complaint in the customer's words, then what you did, then what you recommend with a quote number and price.
4. Readings, then line items with Disc and Tax marked on each.
5. In the spreadsheet, yellow cells are inputs. Set the discount and tax rates in the Rate column of the totals block, duplicate the Invoice tab per job and export to PDF.

When the template stops being enough

The template is step one, and for a one-truck shop it can stay step one for years. The tell is the office's week: Monday typing line items off carbon copies, Wednesday calling about unpaid invoices, Friday re-keying totals into QuickBooks.

The Free plan of Deepsel sends this same invoice without the typing. You set up the price book once (the diagnostic, your flat-rate tasks, parts, refrigerant per pound), build the job from it, turn the job into an invoice and send it. The customer gets an email with a link to the invoice and pays by card. Card payments are 3.3% + 30¢. Free covers 30 estimates and 30 invoices a month for your whole team, with no card to start; Pro is $29 a month for unlimited estimates and invoices. Invoicing for contractors shows the five steps with screenshots. One honest gap: QuickBooks sync is coming soon to the Max plan but isn't out yet, so if QuickBooks keeps your books, the totals still go in by hand for now. Prices are on the pricing page.

Frequently asked questions

What should be included on an HVAC invoice?

Your company name, address, phone and license number (Texas requires the number on every invoice), the invoice number and dates, the bill-to and service addresses, the make, model and serial of each unit, what the customer reported and what you found, the readings you took, line items for the diagnostic, the repair or labor, parts, refrigerant by type and pound, filters and permits, the member discount, sales tax, deposits and the balance due, then payment terms, the warranty and the customer's approval.

Should HVAC contractors itemize parts and labor on an invoice?

Show the parts, not your cost. A flat-rate price per task is fine, but customers push back on a single line like 'warranty blower motor - $1100.' Listing each part with its part number and selling price, the refrigerant by the pound and the readings that justified the repair answers most questions without showing your markup. Use the same pricing method on the quote and the invoice.

How much do HVAC companies charge per pound of refrigerant?

Trane puts R-410A at $40 to $90 a pound installed and R-22 at $100 to $250. HomeGuide's R-410A range is $50 to $100 a pound installed against $4 to $8 wholesale. Put the type, the pounds added and the price per pound on the invoice. A low charge means a leak, so quote the leak search on the same invoice.

Do HVAC contractors charge sales tax on labor?

It depends on the state. Texas doesn't tax labor to repair residential property but taxes nonresidential repair in full. New York taxes repair and maintenance labor and materials alike, and exempts a capital improvement when the customer gives you Form ST-124. In California the contractor pays tax on materials, equipment such as a furnace is taxed on its selling price, and a separately stated installation fee is nontaxable labor. The template has a Tax box on every line so the invoice follows your state's rule.

Is there an HVAC invoice template in Excel or Google Sheets?

Yes. The Google Sheets copy and the .xlsx have three tabs: a blank invoice with live formulas for line totals, member discount, sales tax and balance due, a filled-in example, and notes with the state rules. The Word, PDF and Google Docs versions are the same invoice as a printable form, for techs who fill invoices in by hand.

Does an HVAC invoice need the contractor's license number?

In Texas, yes: 16 TAC 75.71 requires the licensee's number and the TDLR notice on all proposals and invoices for air conditioning and refrigeration work. Florida requires the number on every offer of services, proposal, bid and contract, and California on construction contracts, bids and advertising. Printing it on every invoice covers all three.
