Understand your home's energy use before buying a solution.
A higher bill can reflect use, rates, weather, or billing changes. This cluster helps you build a baseline, investigate the house, and compare assessment options before making an upgrade decision.
Start with the evidence you have
- Bill seems high? Separate kWh, billing period, and price before guessing at a cause.
- Comfort or draft problem? Plan an assessment and record what can be observed safely.
- Considering insulation? Distinguish air sealing from insulation and check safety implications.
- Ready to choose help? Compare DIY and professional assessments by scope and evidence.
Follow up on what you find
- Investigate a higher electric bill by separating usage changes from price and fees.
- Check heating and cooling questions before assuming equipment needs replacement.
- Investigate door and window drafts before deciding to seal, repair or replace.
- Turn an audit into a work plan with priorities and completion checks.
- Compare efficiency and rooftop solar questions using your household baseline.
- Compare upgrade quotes by evidence, scope, safety and verification.
