Written for people who want to see the meter move.

The Sketchy House Files Archive comes from Sketchy House Files, a YouTube channel about the science behind saving money at home.

The internet is full of heating, cooling and free-power tricks. Some are old wisdom that still works. Some are physics that cannot work.

These books test every one with the arithmetic, price it at stated rates, and give a plain verdict: sketchy or solid.

The goal isn't a gadget. It's a lower bill you can prove on your own meter.

These books are general education, not professional advice. Wood heat, gas, electrical and pressurised hot water work carry real risks; the books say where a licensed pro takes over, and local codes apply. Savings are worked examples at the prices stated in the text, not a promise of what you will save. Payhip handles payment and refunds.
