This Week: Repair Inflation vs. Your Reserve Assumptions

THE CURVE: 49%

BLS CPI data shows HVAC and refrigeration repair costs up approximately 49% since 2020, with appliance repair costs up roughly 33% over the same period, both well ahead of the 30% wage growth over that span. For home warranty administrators, that isn’t a backdrop statistic. It’s a direct input into claims severity, and reserve models still anchored to pre-2020 cost benchmarks are working from numbers the market has already outrun.

Widen the lens and the pressure compounds. The Census Bureau puts the median U.S. home at 41 years old, an all-time high, with more than 5.7 million homes now past the 15-year mark where HVAC systems, plumbing, and major appliances are increasingly likely to require replacement or major repair. A book that’s aging into peak claims exposure at the same time repair costs have structurally repriced upward is not a book that should be reserved the same way it was three years ago.

THE ADMINISTRATIVE ANGLE

Frequency and severity assumptions built on a younger housing stock and lower-cost environment describe a book that no longer exists.

Claims developing over the next 2 to 3 years on contracts written under pre-2024 cost assumptions are exposed on two axes at once: the underlying homes are older and more failure-prone than the vintage the model was built on, and the repair costs feeding severity are running meaningfully above the historical baseline. Blended, portfolio-level severity assumptions will understate true cost on any cohort weighted toward older homes, and that gap doesn’t surface until claims actually develop.

This is less an underwriting failure than a timing mismatch: the asset-aging curve and the repair-cost curve moved in the same direction at the same time, and reserve models built for one environment are now pricing a different one. Administrators who haven’t recalibrated severity assumptions against current BLS repair data in the last 12 months may be carrying more unrecognized loss development than their earnings curve currently shows.

The $39 Billion Home Warranty Opportunity: What DTC Marketers Need to Know

The home warranty piece lays out the same aging-stock and repair-inflation data from the marketer’s side, a 41-year median home age and a 49% run-up in HVAC and refrigeration repair costs since 2020. For administrators, those two data points are direct inputs into reserve assumptions, not just market color.

THE RESERVE QUESTION

HVAC and refrigeration repair costs are up roughly 49% since 2020. When did you last recalibrate your severity assumptions against current BLS repair cost data, and do you know which vintage in your book is most exposed to the difference between historical assumptions and today’s repair costs?

Until next Tuesday,
