Useful, local-minded, and honest about uncertainty.

How we research

We prioritize official jurisdiction pages, adopted-code resources, manufacturer installation documents, and qualified trade guidance. When a guide discusses a local approval process, we link to the responsible public agency where practical.

We distinguish category-level patterns from model-specific requirements. A statement such as ‘many traditional heaters use 240-volt service’ never replaces the selected equipment’s listing, instructions, or a licensed electrician’s design.

How we review and update

Every guide shows a reviewed date. We revisit time-sensitive claims, source links, cost ranges, and local processes as the library grows. Material changes update the page’s modified date and structured data.

The cost tool publishes its starting ranges, adjustment factors, rounding, limitations, and revision date in the calculator methodology.

• Verify local rules with the authority for the exact address
• Verify technical requirements with the final manufacturer documents
• Label cost figures as planning ranges, not guaranteed quotes
• Avoid publishing health-treatment claims or guaranteed financial returns
