HVAC Three-Tier Proposal & Offer Builder
Give customers three distinct choices for heating and cooling service, system maintenance, and diagnostic visits with a clean, customer-friendly comparison.
Editable Essential, Recommended and Complete packages.
Separate scope, quantities, rates, exclusions, extra charges and applicable tax.
Live totals, phone-friendly editing and customer-facing PDF output.
Portable selected-offer JSON for compatible browser-based SGL documents.
Included: Interactive three-tier browser builder, editable three-tier editable online documents, standalone proposal browser and editable online documents, Brand Studio Pro and setup guide. Create customer-ready proposals and use your preferred process to deliver them and collect approvals.
Important: Review all actual pricing, scope, permits, licensing, tax treatment and contract requirements before use. Use a qualified legal, trade-safety or tax professional when specialized advice is required. Payment processing and electronic signatures require separately supported services.
How to use this HVAC tool
Build three genuine choices from the customer's actual requirements: Essential for the defined base scope, Recommended when a logical improvement is valuable, and Complete when additional approved work belongs in the offer. Each tier should have its own inclusions, exclusions, line-item quantities and resulting price.
Industry-specific use: For heating and cooling diagnostics, preventive maintenance and filter replacement, enter actual job measurements and conditions rather than copying a generic industry price. Specify equipment type, service address, diagnostic versus repair authorization, replacement parts, relevant safety conditions and follow-up recommendations. Every customer-facing figure should be reviewed before use.
Before sharing
Check that the Recommended option does not quietly exclude needed work from Essential, that the Complete offer has a credible additional benefit, and that the customer can understand the price difference. Use the PDF output after reviewing taxes, optional extras and approval language. The selected offer can be exported for compatible browser-based SGL documents where supported.
Frequently asked questions
Does it set my prices? No; your quantities, scope and rates do. Are the tiers editable? Yes, the browser offer builder and associated editable proposal templates are intended for customization. Will SGL send it or obtain a signature? Create the finished proposal, then share it and request approval using your preferred tools.
Build a defensible HVAC offer: Use your own HVAC job-cost estimate as the starting point, then specify exactly what equipment servicing, repairs or maintenance tasks each tier includes. Compare the complete HVAC toolkit if you also need operations and office forms. Read the HVAC quoting guide.
