This tool pits the Mini-Split (the gold standard for tiny homes) against the humble Window Unit. It calculates the long-term electricity savings of high-SEER inverter technology vs. the low upfront cost of a window shaker.
It features an “Aesthetics & Noise Visualizer” that demonstrates not just the energy difference, but the quality-of-life difference—showing how a window unit blocks your view and generates noise right next to your head, while a mini-split keeps the noise outside and the view clear.

SEER & Inverters Explained
Window Units are “Bang-Bang” controls: 100% On or 100% Off. This causes temperature swings and high power surges.
Mini-Splits use Inverters to throttle the motor like a gas pedal (e.g., running at 20% power). This maintains perfectly stable temps while using a fraction of the electricity.
A window unit sacrifices natural light and security (it’s an open hole in your house). A mini-split requires only a 3-inch hole in the wall for lines, leaving your windows free for views and emergency egress.
