Who it is for
- US homeowners with a central AC, a heat pump or a mini-split who want the whole picture: what to do now, how to keep it running, who pays when it fails and how to replace it well when the time comes.
- Owners of a two-story house where the upstairs runs hot, and who are also weighing a repair against a replacement.
- Households that also cool a bedroom, a rental unit or an addition with a window, portable or wall unit.
What it is not: tax, legal, engineering or financial advice; it recommends no brand, contractor or maintenance plan.

Get the library, $89- The US AC & Heat Pump Replacement Pack (2026) ($49 on its own): Replace your central AC or heat pump in 2026 without losing a rebate or overpaying: what is left of the incentives and how to claim it, sizing, the SEER2 minimum for your region, 20 contractor questions, a three-quote comparison sheet and the installation-day checks.
- The AC & Heat Pump Owner's Handbook: Maintenance and Troubleshooting (2026) ($29 on its own): A year-round maintenance calendar, the safe checks you can do yourself, symptom-by-symptom troubleshooting (water on the floor, ice on the lines, warm air, short cycling, noises, smells), what a real tune-up includes, the truth about refrigerant recharges and the records that protect your warranty.
- Hot Upstairs, Cold Downstairs: The Fix-It Workbook for Uneven Cooling (2026) ($24 on its own): Find out why your second floor stays hot with a one-weekend diagnosis, then fix it in the right order: settings and dampers, return air, attic air sealing and insulation, duct sealing, balancing, zoning or a second system, with logs and contractor scopes.
- Who Pays When Your AC Breaks: The Warranty, Home Warranty and Insurance Claims Workbook (2026) ($24 on its own): Know which promise pays when your AC or heat pump fails, register and transfer in time, file a claim that holds up and appeal a refusal, with trackers, a claim log and letters.
- The Room Air Conditioner Handbook: Window, Portable and Through-the-Wall Units (2026) ($19 on its own): Choose the right room unit for your windows and your lease, size it with the ENERGY STAR table, read CEER and SACC, install it safely on the right circuit, seal it, and work out what a summer costs at your own rate.
