Frequently Asked Questions
What should a complete HVAC estimate include?
A complete HVAC estimate should list your business name, license details, customer contact information, specific job site address, system load calculation summary, proposed equipment specifications (SEER2 rating, tonnage, brand, model numbers), scope of work, itemized labor hours, materials (line sets, composite pads, disconnects, thermostats), permit fees, equipment disposal fees, warranty terms, payment schedule (e.g. 50% deposit), and proposal expiration date.
How much deposit should an HVAC contractor request on an estimate?
For major equipment replacements, heat pump retrofits, or ductwork installations, a 30% to 50% upfront deposit upon proposal signing is standard practice across the trade. This covers wholesale equipment procurement and reserves installation crew scheduling.
How does an HVAC estimate convert to a work order and invoice?
Once the homeowner accepts the estimate, issue an HVAC Work Order to dispatch your field installation crew with job site access notes and equipment specs. Upon completion, convert the work order into a final HVAC Invoice with 1-click on Invoza.
Should equipment warranties be listed on the estimate?
Yes. Always detail manufacturer warranties (e.g., 10-year compressor & functional parts warranty) alongside your company's installation labor warranty (e.g., 1-year or 2-year craftsmanship guarantee) to give customers peace of mind.
What scope exclusions should be noted on an HVAC estimate?
Clearly list exclusions such as required main electrical panel upgrades, municipal plan check delays, unforeseen concealed structural framing fixes, or ductwork repairs beyond connection points to avoid billing disputes later.
