About Dwellvance

Our Mission

Dwellvance exists to make home-upgrade decisions easier to understand. Major improvements can involve significant costs, uncertain savings, incentives, and complicated trade-offs. We believe homeowners should be able to understand those factors before making a major investment.

What Dwellvance Is

Dwellvance is a home-upgrade intelligence platform. It combines planning calculators with explanatory guides to help homeowners understand their home, evaluate potential improvements, compare the economics, and decide what to investigate next.

Our calculators are designed for the early stage of a decision. They help you decide whether an upgrade is worth investigating further. They do not replace professional assessments, contractor quotes, or confirmation of incentive eligibility.

Our Tools

• Heat Pump Calculator

  Compares your current heating system with a heat pump: operating cost, installation cost, incentives, annual savings, and simple payback.

• Solar Calculator

  Estimates solar system size, annual production, potential electricity savings, installation cost, and simple payback.

• Insulation Planning Tool

  Helps you review insulation needs and target R-values for your home.

• Battery Storage Tool

  Helps you think through battery size, backup needs, and potential savings.

• Home Upgrade Calculator

  A planning-level tool that helps you decide which upgrade may deserve attention first. It does not estimate exact costs or paybacks.

Our Approach

• Transparent methodology. We document the assumptions and methods behind our calculations.
• Evidence over hype. We aim to use credible data sources rather than unsupported claims.
• Home-specific context. Upgrade decisions depend on the home, location, existing systems, energy costs, and other factors.
• Decision support, not sales. Dwellvance does not sell heat pumps, solar systems, or contracting services.

What We Don't Do

• We do not sell heat pumps, solar systems, or contracting services.
• We do not present estimates as guaranteed outcomes.
• We do not require registration to use the calculators.
• We aim to be clear about assumptions, limitations, and data sources.
