Energy savings calculator FAQs
How does the energy savings calculator work?
It multiplies equipment power draw by run hours and your electricity rate to get annual energy cost, then applies your expected efficiency improvement to estimate yearly savings, payback period and five-year net benefit.
What efficiency improvement should I assume?
Typical HVAC tune-ups and controls upgrades deliver 5-15%. Replacing failing compressors, motors or older units with high-efficiency equipment commonly lands between 20% and 40%. Use manufacturer data when you have it.
Can I share the results with a customer?
Yes. Every input is stored in the page URL, so the Copy shareable link button gives your customer the exact same numbers. You can also print the results to PDF and attach them to a quote.
Is this calculator free?
Yes — free, no sign-up, no watermark. It is built for HVAC, refrigeration, plumbing, electrical and facility service contractors selling efficiency upgrades.
Can EcoService OS generate savings estimates automatically?
Yes. The Eco-Efficiency Up-Sell Engine analyzes equipment on the job and produces savings estimates your crew can turn into a quote on site, with a 14-day free trial.
