dsh-ac-size

Choosing the right AC tonnage is one of the most common sources of buyer anxiety: a unit that is too large cycles short and wastes electricity, while one that is too small struggles even on the hottest days. dsh-ac-size turns that guesswork into a straightforward parameter-based calculation.

Its single ac_size tool takes key room parameters such as floor area, orientation, and insulation quality, then applies an industry-experience estimation model to return a recommended tonnage with a detailed breakdown. The entire implementation is pure Node.js with zero external network calls, so it runs fast, stays offline, and behaves identically everywhere.

It is well suited to homeowners picking an AC for a new build or renovation, property managers matching cooling capacity to rental units or offices, and HVAC professionals who need a consistent, reproducible basis when explaining tonnage choices to clients.
