An HVAC estimate tells a customer what a heating or cooling job should cost before you start: the equipment, the labor, the refrigerant and the permit. Use this free HVAC estimate template to list it all, add tax and a deposit, and download a PDF or Word file. There is no account to create.
What it is
An HVAC estimate is a written price for heating, cooling or ventilation work. It names the system, the job, the equipment and its size, the labor, the parts and the fees. It is a best guess based on what you can see, so it should say what could change the price, such as hidden ductwork problems or an electrical upgrade. For a replacement or a new system, many contractors size the equipment with a load calculation instead of copying the old unit, and it helps to say so. If the job involves refrigerant, US federal rules require technicians who maintain, service, repair or dispose of that equipment to be certified under EPA Section 608. A quote is different from an estimate. A quote is a fixed price.

Common mistakes
- Pricing the unit without the install extras such as lines, drain, disconnect and thermostat.
- Leaving out the equipment model, size and efficiency rating, so the customer can't compare quotes.
- Forgetting permit and inspection costs.
- Not including removal and disposal of the old equipment.
- Not saying what happens if the ductwork or wiring needs work.
- Giving no warranty terms for parts and labor.
- Not explaining how the system was sized.
- Leaving off a valid-until date while equipment prices are changing.

Repair, replace or install?
- Repair: show the diagnostic fee, the parts, the labor and any warranty on the repair.

- New installation: show how the system was sized, any ductwork and electrical work, and the permit.
Common questions about the numbers
The discount comes off the subtotal first. Tax is then worked out on the taxable items after the discount. The deposit is a share of the total, and the balance is what is left.
Frequently asked questions
What should an HVAC estimate include?
Your details and license number, the customer and site, the job and the system, the equipment model and size, itemised labor and parts, permit fees, removal of old equipment, warranty terms, what isn't included and how long the price holds.
What is the difference between an HVAC estimate and a quote?
An estimate is a best guess that can change if the job changes. A quote is a fixed price. If you can price the whole job firmly, use a quote.
Do HVAC technicians need a certification to handle refrigerant?
In the US, yes. EPA Section 608 requires technicians who maintain, service, repair or dispose of equipment containing refrigerant to be certified, and EPA says adding or removing refrigerant on a mini-split during installation counts. Outside the US, check your local rules.
Should an HVAC estimate mention a load calculation?
Many contractors size a new or replacement system with a load calculation instead of copying the old unit, and it can help to say so. The form has a box for it.
Who pulls the permit?
It depends on your local rules and your arrangement. The form lets you say whether you pull the permit, the customer does, or none is needed, and you can list the fee as a line.
How long should an HVAC estimate be valid?
Equipment prices can change, so many contractors use 14 to 30 days. Put the date on the estimate.
Can I ask for a deposit?
Many HVAC jobs do, especially when equipment has to be ordered. Check your local rules on deposits.
