Free HVAC Invoice Template for Contractors (2026)
Download a professional HVAC invoice template with service call fees, labor rates, refrigerant tracking, and equipment warranty fields. Start invoicing in under 2 minutes.
If you're running an HVAC business, your invoices need to look different from a generic template. Service call fees, refrigerant by the pound, equipment model numbers, warranty periods — these aren't fields you'll find in FreshBooks or Wave.
What Makes a Good HVAC Invoice?
A professional HVAC invoice should include:
- Service call / diagnostic fee — typically $75-$125 as a flat rate
- Labor broken out by technician tier — journeyman vs apprentice rates
- Refrigerant charges by weight — R-410A, R-22 (if still servicing), priced per pound
- Equipment model and serial numbers — for warranty tracking
- Warranty period noted on the invoice — 90-day labor warranty is standard
The Problem with Generic Invoice Tools
Most invoicing apps give you "Description + Quantity + Price" and call it a day. That works for a freelance designer. It doesn't work when your customer needs to see that you charged $45/lb for 3 lbs of R-410A and the compressor is still under manufacturer warranty.
SendPaid's HVAC template includes all of these fields built in. No customization needed — just pick the HVAC template and start typing.
