Why Contractors Love This Calculator
I pull this up on every sales call now. When a homeowner sees that their old SEER 10 unit is costing them $600 more a year than a 16, the upgrade conversation basically has itself. Way better than handing them a brochure.

Our AC died in July — worst timing possible. This calculator helped us compare a basic 14 SEER replacement vs. a 20 SEER unit. The payback period was 6.2 years, and we plan to stay in this house for 15+. Made the decision easy.

I use this for home energy assessments. Being able to auto-fill state rates and cooling hours saves me time, and the CO2 output gives clients a number they actually care about. Clean tool, no fluff.
