01 / Mission
Help the homeowner see the tradeoff before the sales process closes it.
HVAC and water-heating choices often arrive with urgency, unfamiliar terminology, and uneven information. The product organizes the facts that change the decision and makes every numeric assumption editable.
02 / Independence
The calculation does not know who wants the job.
Home Upgrade Toolkit does not accept contractor commissions, sell quote rankings, or let advertising alter a result. Future commercial content must remain visually and operationally separate from calculations, editorial standards, and source decisions.
03 / Current product
Six tools, one consistent standard.
- Repair or replace evidence ledger
- Structured contractor quote check
- HVAC lifecycle comparison
- Water-heater fit and cost comparison
- Official incentive verification path
- Device-local equipment planner
Core calculations are deterministic. Ordinary use requires no account, no AI inference, and no exact address.
04 / Limits
A planning tool is not a diagnosis, design, or bid.
The site does not replace equipment inspection, load calculation, code review, combustion or electrical safety work, legal or tax advice, or written contractor scope. Local price evidence remains unpublished until its source and classification gates pass.
