See how your home actually works.

Your air conditioner doesn't make cold air — it moves heat out of your house. Watch the refrigeration cycle in motion, part by part.

From the thermostat's call to warm air at the vents — follow the burn, the heat exchanger, and the one crack that makes a furnace dangerous.

A heat pump is an air conditioner that can run in reverse. Flip the mode toggle and watch the refrigerant flow change direction.

Pressurized supply in, gravity drains out, and a vent stack that keeps it all flowing. See the whole water path through your house.

Cold water down the dip tube, heat at the bottom, hot water off the top — and a sacrificial rod quietly rusting so your tank doesn't have to.

Follow the power: through the meter, past the main breaker, into branch circuits — and the safety layers standing between electricity and everything you love.

Refrigerator, dishwasher, laundry, disposal — four machines, four diagrams. Tap through each one to see what's inside and what wears out.
