Big Energy Savings

Try Our SEER Energy Savings Calculator
Wondering what kind of difference a new system could make for your energy bills? Use our interactive SEER calculator to see potential savings based on your current system’s rating and your average energy costs in Dallas.

Many homes in the Dallas-Fort Worth area still rely on older systems with SEER ratings as low as 8 or 10. That means those systems are working twice as hard (and burning twice the electricity) compared to today’s high-efficiency models. Upgrading could save you hundreds every year — and we’ll show you exactly how much.

Calculations are based on $0.156/kWh avg for electricity and $2.41 per therm avg for natural gas, 2300 hours per average cooling season and 77 million BTU's per avg heating season in North Texas.
