Frequently Asked Questions
How can I lower my home energy costs?▾
Start with the Appliance Energy Calculator to identify your biggest electricity consumers. HVAC typically accounts for 40-50% of your bill. A smart thermostat saves 10-15% ($100-200/year). LED lighting saves $75-150/year. Washing clothes in cold water saves 80% of washer energy. These five changes typically save $300-600 annually.
When should I replace vs repair home systems?▾
The general rule: if a repair costs more than 50% of replacement and the system is past its midlife, replace. HVAC systems last 15-20 years, water heaters 8-12 years, roofs 20-30 years. Use our Home Warranty Calculator to evaluate whether coverage makes financial sense for your situation.
