Field notes
The homepage organizes material around the replacement decision, then branches into sizing, cold-climate performance, mini splits, troubleshooting, and rebates. It links to calculators for running costs, equipment sizing, and emergency heat. The site says its estimates draw on household bills and rates, manufacturer figures at relevant temperatures, and dated sources; the extracted page does not show the calculators’ inputs or outputs.
