Built for real project planning

HomeCostEngine field guides are designed to sit beside measurements, contractor proposals and the free calculators on this site. The goal is not to give you one magic price. It is to help you define scope, identify assumptions and ask better questions before money is committed.

Use this guide for personal planning and pair it with the relevant HomeCostEngine calculators and cost guides.

Inside the 104-page edition

The buyer's guide is structured around complete installed scope rather than equipment price alone. It helps you document comfort problems, ask how the system was sized, compare matched equipment, understand ductwork and controls, and confirm what commissioning, permits, warranties and startup work are actually included.

The PDF contains 20 planning modules. Every module includes a concept page, a scope worksheet, a contractor-quote check and a decision/action page. The final 20 pages are reusable worksheets for measurements, allowances, risk, schedule, change orders, payments, warranties and closeout.

Major sections

  1. 1. Comfort problems and system goals

  7. 7. Permits, commissioning and warranties
  8. 8. Quote comparison, startup and maintenance

Use the book with these HomeCostEngine tools

These internal tools are designed to help with measurements, quantity checks and quote organization. The book gives you the longer planning workflow around those calculations.

Independent reference links

External resources are provided as starting points for independent verification. Local code, permit, engineering, manufacturer and contractor requirements can differ by project and jurisdiction.

What this book does - and does not - replace

The guide is for homeowner planning, budgeting and contractor conversations. It does not replace a site inspection, contractor proposal, engineering design, legal advice, manufacturer installation instructions, permit review or local code requirements. Use the worksheets to record those project-specific answers when you receive them.

Planning note: This PDF is educational information, not a contractor bid, engineering opinion, legal advice or code approval. Verify project-specific requirements with qualified local professionals.
