About ManualHarbor

ManualHarbor helps you find clear, trustworthy instructions for the products in your home and business — quickly, by model number.

What you will find here

The library covers 52,264 certified products from 1,916 brands, plus 296,507 AHRI-matched heat pump systems. Every model page combines verified specifications with an owner guide written for that product type and configuration: safety information, installation and setup, everyday use, maintenance schedules, troubleshooting and running costs.

Where the data comes from

Model numbers, dimensions, capacities and efficiency ratings come from the ENERGY STAR certified products database published by the U.S. Environmental Protection Agency. We refresh the data regularly; the current data set was retrieved on October 7, 2026.

Independence

ManualHarbor is not affiliated with, endorsed by or sponsored by any manufacturer, the EPA or the ENERGY STAR program. Brand names and model numbers are used only to identify products. Our guides complement — they do not replace — the documentation supplied with your product.
