How to use the estimator

Turn your real job costs into a clear customer estimate

  1. 1. Describe the job. Add the customer, location, dates, and a specific project title.
  2. 2. Enter your rates. List labor, materials, equipment, fees, and quantities using current figures from your business.
  3. 3. Review pricing. Apply your markup, discount, tax, fee, and deposit rules, then verify the live total.
  4. 4. Send a professional document. Clarify scope, exclusions, and terms before downloading the PDF.

What a strong HVAC estimate includes

A useful estimate makes the proposed work easy to understand. Include itemized services, quantities, unit rates, the job location, scope, exclusions, validity period, taxes, deposit requirements, and payment terms.

How the calculation works

Line items are calculated as quantity × unit price. Markup is added to the subtotal, discount is deducted, additional fees are included, and tax is calculated on the resulting taxable amount. Currency values are rounded to cents.

Common estimating mistakes

  • Leaving labor, travel, disposal, or permit work out of the scope
  • Applying markup without checking whether it covers overhead and profit
  • Using old supplier pricing or forgetting tax treatment
  • Sending a total without clear inclusions, exclusions, and payment terms

HVAC estimate considerations

  • Equipment model and warranty
  • Refrigerant type and quantity
  • Permit and inspection requirements
  • Access, travel, and disposal
