Frequently asked questions

How do I write an HVAC estimate for a system replacement?

Start with the equipment (model, size, efficiency), then installation labor, materials such as line sets and pads, removal of the old unit, permits and warranty. Many techs add two or three options at different efficiency levels.

Should HVAC invoices show refrigerant separately?

Yes. Refrigerant is billed by the pound and prices change often, so a separate line keeps the invoice transparent and makes service calls easier to compare.

Is an estimate legally binding?

Generally, no. An estimate is an approximation. It becomes part of a binding agreement when the customer signs and accepts it, and many contractors attach their contract terms at that point. Rules vary by state and country.

How long should an estimate be valid?

Thirty days is common. Use a shorter window when material prices are volatile.

Can I turn an estimate into an invoice?

Yes. With a free HardHat Quote account you can save the estimate, and on Pro you can convert an approved estimate into an invoice in one click.
