The True Lifetime Cost of Every Major Appliance
A $2,000 heat pump that saves $800/year beats a $1,200 gas furnace. But only if gas prices rise as projected, incentives apply to your situation, and maintenance holds. We model all of it -- Monte Carlo simulation across 10,000 energy price scenarios, IRA incentive stacking, and Weibull maintenance curves.

DOE-Grade Lifecycle Analysis, Built for Homeowners
The same lifecycle cost methodology used by the Department of Energy's Building Technologies Office -- personalized to your ZIP code, energy rates, and available incentives.
Lifecycle Cost Analysis
NPV of purchase price, installation, annual energy cost with escalation, maintenance, and repair probability over the equipment's full lifetime. Not just the sticker price.
Monte Carlo Energy Projections
10,000 simulated energy price paths using historical EIA state-level volatility. See your P10-P90 cost range over the ownership horizon, not just a point estimate.
IRA Incentive Stacking
Federal IRA credits ($2,000 HVAC + $2,000 water heater), state rebates, and utility rebates stacked per IRS rules. Credit reduces basis before rebate. We handle the math.
Technology Crossover Analysis
Gas furnace vs. air-source heat pump vs. mini-split. Gas vs. tankless vs. heat pump water heater. Side-by-side TCO comparison with breakeven year calculation.
Maintenance Cost Modeling
Weibull failure distribution calibrated from DOE equipment lifetime studies. Know the probability of a major repair at each year of ownership and budget accordingly.
Sensitivity Analysis
Tornado chart showing which variables most affect the TCO ranking: energy price, discount rate, equipment lifetime, maintenance frequency. Know what matters most.
