What a estimate should include
- Your license number and the load calculation the sizing came from
- The homeowner and the service address
- An estimate number, the date, and the equipment model quoted
- Itemized equipment, labor, and ductwork
- System size, efficiency, and warranty in the scope
- A validity window and the equipment lead time from the supplier
- A signature line, and the deposit that releases the equipment order
Common estimate mistakes to avoid
- Sizing by rule of thumb instead of a load calculation
- Forgetting ductwork, permits, or disposal
- Leaving the efficiency rating and warranty vague
- No deposit on a high-cost equipment order
- Sizing the system from the old unit instead of a load calculation
What happens after you send it
A estimate does its real work after it leaves your hands, and that part is not on the document.
Equipment is ordered before it is installed, so the quote ages
Between approval and install sits a supplier lead time you do not control, and in a heat wave that gap is when a customer calls someone with a unit on the shelf. Putting the current lead time on the estimate is what keeps an approved job from quietly going elsewhere.
Registration is what makes the warranty real
Manufacturer parts coverage usually depends on the equipment being registered within a window after install, and nobody tells the homeowner that. Doing it yourself and recording the date turns a promise on the estimate into something they can actually claim.
Rebate paperwork arrives after you have moved on
Utility rebates and tax credits are claimed by the customer, weeks later, using documents only you have. Sending them the model numbers and the invoice unprompted is the last step of the job, and skipping it is the most common reason a good install ends in frustration.
Stop filling in templates
An install bid competes against two or three others. Smarfle builds HVAC estimates from your equipment and labor costs, sends them for online approval and a deposit, and turns the accepted estimate into a scheduled install and invoice, so you respond first and look the most professional.
