Compare HVAC quotes side by side

The automated comparison tool is launching soon. In the meantime, email your proposals to [email protected] or call 206-418-9153 and we’ll walk through them with you using the same checklist below — or use the checklist yourself to compare line by line.

1 · Upload your proposals

Upload all pages from each contractor together. Use one multi-page PDF or select up to 8 clear photos/screenshots for each quote. Two quotes are required; a third is optional.

Privacy: Your uploaded documents are sent securely to an AI service for this analysis. King County HVAC Guide does not save the uploaded files to its database. Please avoid uploading financing applications, Social Security numbers or other unnecessary sensitive information.

Quote A — upload all pages
Every selected file should belong to the same contractor proposal.
Quote B — upload all pages
Every selected file should belong to the same contractor proposal.
Quote C (optional) — upload all pages
Every selected file should belong to the same contractor proposal.

Note: Uploads are paused for the free launch — please email your quotes instead (above).

AI can make mistakes. Verify model numbers, prices and contract terms against the original proposals.

2 · Your side-by-side comparison

“Not stated” means the tool could not find that item in the proposal. It does not necessarily mean the contractor will not provide it.

Use this as a question generator, not a contractor ranking. A lower price is not automatically a better value, and a missing line item may simply need clarification.

Your side-by-side comparison will appear here once you upload at least two quotes above and click Compare my quotes.

What the tool checks

Equipment & sizing

Exact model numbers, system type, capacity, efficiency, staging, Manual J and Manual S references.

Ducts & airflow

Duct evaluation, modifications, static pressure, airflow testing and related scope.

Installation quality

Permits, electrical work, nitrogen while brazing, evacuation, startup and commissioning language.

Price & protection

Total price, rebates, financing, labor warranty, equipment warranty, maintenance and exclusions.

Important: This tool provides educational document comparison only. It does not inspect the home, verify contractor claims, determine code compliance or replace professional HVAC design and inspection.
