Energy Efficiency Ratio Calculator helps contractors and tradespeople accurately size, spec, and estimate materials and systems.

Formel

EER = Cooling Capacity (BTU/hr) / Power Input (Watts)

Trin-for-trin guide

  1. 1Check equipment nameplate for BTU and wattage
  2. 2Apply the formula using your project measurements
  3. 3Add required safety factors or waste allowances per code

Løste eksempler

Input
12,000 BTU AC, 1200W power input
Resultat
EER = 12000/1200 = 10 (SEER translates to seasonal EER)

Almindelige fejl at undgå

  • Not applying code-required safety factors or derating
  • Forgetting to account for waste and cut losses in material estimates
