Home Health Score

Homeowner Summary

Your Home Health Score is a single number from 0 to 100 that tells you the overall condition of your home's major systems and equipment. It is like a credit score for your house — one clear number that captures a complex picture. A high score means your systems are well-maintained, relatively young, and performing efficiently. A low score means there are issues that need attention, whether that is aging equipment, missed maintenance, or active problems detected by monitoring.

The score is not a pass/fail grade. It is a living indicator that changes over time. When you replace an old water heater, your score goes up. When your HVAC ages another year without maintenance, it goes down. When SAM detects an efficiency drop through monitoring sensors, the score reflects that too. The goal is not to chase a perfect 100 — it is to stay informed about your home's condition and make smart decisions about when to invest in maintenance or replacement.

Your Home Health Score appears front and center in your Shipshape app and is the foundation for the alerts and recommendations SAM sends you.

How the Score Is Calculated

The Home Health Score is a weighted composite of four factors:

1. System Age (35% weight)

Every major system in your home — HVAC, water heater, roof, electrical panel, appliances — has an expected lifespan. SAM compares the current age of each system against its expected lifespan and calculates an age score. A brand-new furnace contributes positively. A 19-year-old water heater with a 12-year expected lifespan pulls the score down significantly.

Age scoring uses a curve, not a cliff. A system at 50% of its lifespan still scores well. The score drops gradually as systems approach end-of-life, then drops more steeply once they pass it.

2. Maintenance History (25% weight)

Regular professional maintenance extends equipment life and catches problems early. SAM tracks whether each system has been serviced on schedule. Systems with up-to-date maintenance records score higher than systems with gaps or no records at all.

This factor rewards homeowners who invest in preventive care. Even an older system with a strong maintenance history scores better than a newer system that has been neglected.

3. Monitoring Data (25% weight)

If you have Shipshape sensors installed, SAM factors in real-time performance data. An HVAC system running efficiently and cycling normally boosts this component. One drawing excessive power or showing abnormal temperature differentials lowers it.

For homes without monitoring hardware, this component is derived from the most recent professional assessment and any available utility data. Homes with active sensors get the most accurate and responsive score.

4. Condition Assessment (15% weight)

This factor comes from your most recent Home Health Assessment — the professional inspection performed by your service technician. It captures visual condition, wear patterns, and technician observations that sensors and age alone cannot detect. Things like corrosion on a water heater tank, a condenser coil showing signs of damage, or ductwork with visible deterioration.

This component updates each time your service professional performs an assessment.

Score Ranges

| Range | Rating | What It Means | |-------|--------|---------------| | 80 - 100 | Excellent | Your home's systems are in great shape. Equipment is relatively new or well-maintained, monitoring shows strong performance, and no major issues are flagged. Keep up your current maintenance routine. | | 60 - 79 | Good | Your home is in solid condition with some areas to watch. You may have a few systems approaching the end of their expected lifespan or some maintenance that is overdue. SAM will highlight specific opportunities to improve. | | 40 - 59 | Fair | There are meaningful issues that deserve attention. Multiple systems may be aging, maintenance gaps exist, or monitoring has detected performance problems. Prioritize the items SAM flags as highest impact. | | 0 - 39 | Critical | Your home has significant risks that need prompt action. This typically means multiple systems past their expected lifespan, major maintenance neglect, or active problems detected by sensors. Work with your service professional to create a prioritized action plan. |

How to Improve Your Score

The most impactful actions, in order:

1. Complete your Home Health Assessment — An up-to-date professional assessment gives SAM the most accurate picture of your home. If you have not had one, this is the single biggest step you can take.

2. Catch up on overdue maintenance — Schedule any maintenance that has lapsed. Annual HVAC tune-ups, water heater flushes, and other routine services directly improve your maintenance history score.

3. Replace end-of-life equipment — Systems that are significantly past their expected lifespan are the largest drag on your score. Replacing them has the biggest single impact. SAM prioritizes replacements by urgency and risk.

4. Install monitoring hardware — Active sensor data gives SAM real-time performance visibility and improves the accuracy and responsiveness of your score.

5. Address flagged issues — When SAM sends you an alert about an efficiency drop, unusual reading, or maintenance reminder, acting on it improves both the underlying condition and the score.

Score Components by System

Each major system in your home has its own sub-score, which contributes to the overall composite. In the Shipshape app, you can drill into the score to see:

• HVAC — Heating and cooling equipment age, maintenance, and performance
• Plumbing — Water heater, supply lines, fixtures, and leak risk
• Electrical — Panel age, wiring condition, and power quality
• Roof & Exterior — Roof age, siding, gutters, and weather exposure
• Appliances — Major appliances tracked in your home profile
• Safety Systems — Smoke detectors, CO detectors, fire extinguishers

This breakdown helps you and your service professional focus investment where it matters most.

For Service Professionals

The Home Health Score is a powerful tool for customer conversations. It provides an objective, data-driven framework for discussing maintenance and replacement recommendations. Instead of "I think your water heater is getting old," you can show a customer exactly how that system is affecting their overall home health, and what replacing it would do to their score.

Dealers see aggregate Home Health Scores across all connected homes in their dashboard, helping them identify the highest-need customers and proactively reach out with relevant service recommendations.
