Frequently Asked Questions

How often should I perform a home energy audit?

Perform a comprehensive DIY audit annually, with mini-audits seasonally. Professional audits every 3-5 years or after major home modifications provide the most value.

What’s the most cost-effective improvement for North Texas homes?

Air sealing combined with proper HVAC maintenance typically provides the highest return on investment, often saving 15-25% on energy bills for under $200 investment.

Should I prioritize heating or cooling efficiency improvements?

In North Texas, prioritize cooling efficiency due to our extended summer season, but don’t neglect heating efficiency for the 2-3 months of significant heating demand.
