HVAC Invoice Template

Include your business name, contact details, invoice number, invoice date, customer details and service address. Describe the heating or cooling work completed, service dates, quantities, prices and applicable taxes. Identify the equipment serviced and any refrigerant added. Show deposits or credits, the amount due, due date and payment instructions. Include license, certification and permit references when relevant or required.

Use the pricing arrangement agreed with the customer. A diagnostic fee may cover dispatch and initial troubleshooting, while the authorized repair has a separate price. Explain what each charge includes. If the diagnostic fee is credited toward the repair, show the credit clearly so the same service is not billed twice.

Identify the refrigerant type, quantity charged and agreed pricing method. If billing by weight, use the measured quantity and the agreed unit rate. Also describe related diagnostic or repair work. The refrigerant quantity billed is not necessarily the amount recovered from the system or the system's full charge. Follow the applicable EPA handling and recordkeeping requirements.

Document the condition found, any leak investigation, the work actually performed and the refrigerant added. EPA Section 608 rules impose specific leak-repair and verification requirements for certain larger appliances containing ozone-depleting refrigerants, but those requirements do not automatically apply to every residential air conditioner. Follow applicable regulations, equipment instructions and the authorized scope. Do not claim a leak was repaired unless that work was completed.

EPA Section 608 technician certification is required for covered activities that could release refrigerant, including certain servicing, repair, installation and disposal activities. Certification requirements depend on the work and equipment. This federal technician credential is separate from state or local business and contractor licensing.

Record the manufacturer, model number, serial number and installation date for supplied equipment. These details help identify the correct unit for service history, warranty registration and future claims. For a split system, record the relevant indoor and outdoor components. Keep lengthy specifications in a connected equipment record when they do not fit clearly on the invoice.

Identify the accepted installation scope, equipment supplied, agreed price and work completed. Record major equipment models, serial numbers and the installation date. Include permits, related work and equipment disposal only as the agreement provides. Show any approved additions, deposits or progress payments before calculating the balance due.

An AHRI Certified Reference Number identifies a certified equipment combination, such as a matched indoor and outdoor air conditioning system. It may help support equipment performance documentation or certain rebate applications. Include the reference when relevant and verified, but do not invent one or assume every installation has an applicable AHRI certificate.

Use the price agreed for the specific maintenance service or system. Describe the work actually completed, such as inspection, cleaning or filter replacement. If the visit is included in a prepaid maintenance agreement, show that it was covered and charge separately only for authorized work or items outside the plan.

Reference the customer's maintenance agreement and identify the completed service visit. Apply the plan's included visits, discounts and covered services correctly. Do not charge again for work already paid for through the plan. List separately approved repairs or parts that the agreement excludes.

Yes, when filters are supplied or replaced, recording the size, type and quantity is useful. For example, you can describe a 16 x 25 x 1 inch MERV 8 filter. This helps customers and technicians identify the correct replacement during future service. Only state the specifications actually supplied.

Identify the installed equipment and refer to the actual manufacturer warranty and any separately agreed installer warranty. Record model and serial numbers and the installation date. Explain whether the installer provides separate labor coverage. Do not promise a universal warranty length or suggest that a manufacturer's parts warranty automatically pays for repair labor.

Not necessarily. Many standard manufacturer limited warranties cover specified defective parts but exclude service labor. Coverage varies by manufacturer, model, registration status and warranty terms. Check the actual warranty before marking a repair as covered or charging the customer.

Denver has local contractor licensing classifications for heating, ventilation, refrigeration and related mechanical work. Requirements depend on the work performed. Technicians handling refrigerants may also need federal EPA Section 608 certification. Record the relevant credentials when applicable, and verify the required permit and license classification for the job.

Permit requirements depend on the equipment and work. Denver's published guidance distinguishes certain existing-system repairs from new heating equipment installations, and its permitting system supports mechanical permits. Check the applicable requirements before starting work. Include the permit reference and agreed fees when applicable, without implying that an issued permit means an inspection has passed.

The answer depends on the transaction and applicable state and local rules. Colorado distinguishes qualifying lump-sum construction contracts, time-and-materials contracts and certain retail equipment sales. A contractor may pay tax when purchasing building materials or collect tax on a qualifying retail sale. Denver also has local tax rules. Do not automatically apply sales tax to every equipment, filter or labor line.

It can apply to qualifying retail sales involving delivery of taxable equipment. Colorado's Department of Revenue specifically distinguishes a service call that involves replacing a part from the retail sale and delivery of a replacement HVAC unit. Qualifying time-and-materials and lump-sum contractor arrangements can also have different treatment. Check the current rules rather than automatically applying the fee to every visit.

Use the emergency callout fee or higher labor rate disclosed and agreed with the customer, subject to applicable law. Distinguish the emergency premium from the ordinary diagnostic or repair charges. Do not charge twice for the same dispatch or labor time.

Reference the original job, equipment and warranty terms. Describe the reason for the return visit and the work completed. Apply the actual warranty coverage, including any applicable parts or labor credits. Show a zero amount due when the work is fully covered, and explain any legitimately chargeable services.

Use the payment terms agreed with the customer and applicable legal requirements. Small service visits may be payable upon completion, while equipment installations may use deposits, milestones or final payments. Show any payments already applied, the outstanding balance and the due date.

Explain the new finding and the proposed work and price before billing for the additional scope. Follow the agreement's approval process and document the authorization. Only include completed and appropriately authorized work on the final invoice, with references to any approved changes.
