Where Your Heating and Cooling Money Actually Goes.

The hottest of three average houses, the one in Florida, spends $858 a year on heating and cooling. The Dallas house spends $2,062, and two thirds of that is heating. I built two calculators to find out why, and where the money actually goes. In this video: what actually makes a house hot and cold (ducts, sunlight through windows, slab floors, air leaks, walls, and the stuff inside), the most average houses I could find in California, Texas, and Florida pulled from the Department of Energy's 550,000-house simulation, why a 100% efficient electric heater is the worst heating system in the whole video, how ducts can be costing you big, how much heat a gas stove really adds (there is pasta math), and a head-to-head between a lookalike-house calculator and a custom model of your exact house, with an honest answer on which one to use. Cooling tips start at 55:52 and the calculator tutorial at 62:10. 🔧 Try the calculator: https://efficienado.com/home-energy-u... 🌐 Site: https://efficienado.com 📸 Instagram:   / efficienadodotcom   ☕ Support (no sponsors, ever): https://ko-fi.com/efficienado Mentioned in this video: AC at Night:    • The Two AC Settings That Can Swing Your Bi...   Home Upgrade Calculator:    • How to find Home Upgrades that save Thousa...   If you want more free calculators like this one, a like or a subscribe costs you nothing.
