Why Sun Belt Markets Are Hardest Hit
Higher-capacity equipment
Phoenix homes need larger, more powerful HVAC systems than Chicago homes of similar square footage. The extreme heat load requires tonnage that costs more to manufacture and install.
More frequent replacement cycles
Phoenix HVAC systems run harder for more hours per year than virtually any other market. This drives faster wear, more frequent replacement — more claims, higher prices.
Supply chain impact on high-demand units
4+ ton units (common in larger Sun Belt homes) saw more severe supply chain disruption than smaller units. Equipment costs spiked more for the larger equipment Phoenix needs.
Labor market pressure
HVAC technician wages in Phoenix, Houston, and Miami have increased significantly. These are high-demand markets competing for limited skilled trades labor.
The Cap Adequacy Problem
Most major home warranty companies set caps years ago and haven't adjusted them proportionally to equipment cost increases.
$3,000 cap — Phoenix
$5,000 cap — Phoenix
In absolute terms, the cap covers more. In percentage terms, it covers less — because equipment costs rose faster than caps. For Sun Belt markets, caps need to be $5,000+ per unit to provide meaningful coverage at current replacement costs.
Cap Adequacy by Company
Adequate Sun Belt caps ($5,000+)
Inadequate Sun Belt caps
Practical Guidance for Sun Belt Homeowners
If your HVAC is over 10 years old and you're in Phoenix, Houston, Miami, or a similar high-cost market:
Sun Belt homeowners are regularly receiving claims payments of $3,000–$5,000 and then writing personal checks for $5,000–$9,000 to complete the replacement. This is not a coverage failure — it's working as designed. But it's not what most consumers expect when they buy "HVAC coverage."
