BUILT FOR HVAC

The HVAC app for changeouts, service calls & maintenance plans

Bid the changeout in tiers, finance the big ticket, invoice the service call on the driveway, and put every maintenance agreement on autopay.

Built for how HVAC money actually flows

Everything below is included or one tap away, no modules, no add-on pricing, no sales calls.

🥇

Changeout tiers that sell

Good, Better, Best in one tap. 14 SEER to variable-speed heat pump, and the homeowner talks themselves into the better system.

Maintenance on autopay

Spring and fall tune-up plans bill a saved card automatically, invoiced, charged, and marked paid while you sleep.

🧾

Service calls, closed out

Your rates per ton, per system, per line set, estimates price from your numbers, not national averages.

Why HVAC contractors pick SayEstimate

How HVAC pricing actually works

System changeouts are priced by capacity and efficiency: tonnage and SEER2 rating drive the equipment cost, and the honest way to size is a Manual J load calculation, not square footage folklore. Rules of thumb like 400 to 600 square feet per ton exist, but insulation, windows, and climate swing the real answer, which is exactly why a tiered Good, Better, Best proposal works so well in this trade: same load, three efficiency and comfort levels, customer picks the payment they can live with.

A complete changeout estimate lines out the equipment, the line set (replace, not flush, when the old set does not match the new refrigerant), the pad, electrical whip and disconnect, condensate handling, permit, and start-up. Ductwork is its own scope: if the ducts are undersized or leaking, the best equipment on the market will underperform, and the estimate should say whether duct work is included, excluded, or priced as an option.

SayEstimate's price book holds your rates in exactly these units, and the AI estimating on Pro and Crew drafts line items that show the quantity, the unit, and the math. Prefer paper? The free estimate template is here.
