How Much Can a New HVAC System Save on My DFW Energy Bill?
A 15-year-old 10 SEER system upgraded to a modern 16–20 SEER2 unit typically cuts cooling costs 25–40% in DFW, saving $800–$2,400 per year at the regional average of 13.8¢/kWh. Per the U.S. Department of Energy, replacing an old AC with an ENERGY STAR certified unit can reduce energy use by up to 20% — before factoring in Texas attic-heat penalties.
From Omar, Co-Owner
“This calculator uses the real DFW number — 13.8¢/kWh on Oncor — and the real attic penalty (15 years at 140°F drops your R-6 insulation to R-2). I built it after a Coppell customer showed me her $487 August bill on a 17-year-old 10 SEER unit. We swapped her to an 18 SEER2 Carrier and her July bill the next year was $241. That's not marketing math — that's her Oncor statement on my phone.”
