HVAC Estimating Software

What to look for

• Clarify your mix: service/replacement quoting in the field vs plan-and-spec takeoff from drawings (many shops eventually need both)
• If you already run an FSM with solid proposals and a governed pricebook, prefer that module so estimates share the same customer, job, and invoice record
• Good-better-best or multi-option proposals, mobile presentation, e-signature, and follow-up on open estimates
• Central pricebook or flat-rate library with updates you can actually maintain (parts, labor times, markups)—confirm add-ons like Pricebook Pro / Proposal Pro in a live demo
• Path from accepted estimate to schedule, work order, change orders, and invoice without double entry
• Financing presentation on the proposal when you sell replacements (often an integration—verify with vendor)
• Standalone overlays (flat-rate pricebooks, manufacturer-tied catalogs) when you need deeper HVAC pricing content than your FSM ships; they do not replace dispatch
• Commercial takeoff suites (digital plans, duct/sheet metal) when blueprint bidding is a regular part of the book—expect estimator seats, not tech tablets
• Avoid running a standalone quoter alongside a capable FSM proposal module if techs will refuse to enter data twice
• Never trust directory copy for list prices—confirm packaging, seat counts, and which estimating features are base vs add-on with each vendor
