FREE DECISION TOOLS
Plan before you browse.
These calculators make their assumptions visible. They provide planning ranges—not engineering, electrical or installation approval.
ROOM COOLING
AC capacity starting point
Enter conditioned floor dimensions. The estimator applies a deliberately conservative 60 BTU/h per square foot hot-climate screening factor and simple exposure adjustments; a qualified installer should confirm the final load.
RUNNING COST
Monthly electricity estimate
Use rated input and equivalent full-load hours. Enter the marginal unit price from your own bill; the site does not publish a potentially stale national tariff.
LAUNDRY LOAD
Washer capacity planner
Start from the heaviest normal dry load—not a rare blanket. Confirm that the exact cycle permits bulky items.
IMPORT SAFETY
Voltage compatibility checker
Copy the range from the official rating label. A plug adapter never changes voltage, and this check cannot approve wiring or transformer selection.
Method and limitations
These tools run entirely in your browser and do not submit form values to us. Results are transparent arithmetic or conservative rules of thumb. They cannot inspect insulation, wiring, appliance condition, installation, utility tariff or manufacturer restrictions. Use them to prepare questions and shortlists; verify the final decision with official documentation and a qualified professional where safety is involved.
