People living in these homes are more likely to die from heat in Arizona

In 2024, mobile homes, trailers, and RVs in metro Phoenix accounted for 25% of indoor heat-related deaths, despite making up only 5% of local housing. Many residents, often on fixed incomes, struggle with rising lot rents that hinder their ability to repair or replace aging AC units. Across Pima County and four other rural counties, the proportion of heat-related deaths in mobile homes or RVs is even higher. Kath Noble, president of the Arizona Association of Manufactured Home Owners, emphasized the severe conditions faced by residents in these homes during extreme heat waves. The Maricopa County medical examiner frequently finds that malfunctioning air conditioning systems contribute to such fatalities.

Steven Summerfield's tragic death illustrates the risks, as he passed away after waiting for an expensive repair. The association is working with ASU to develop resources for residents, including emergency plans and tips for maintaining AC systems. With 60% of heat-related deaths in Maricopa County occurring among individuals aged 50 and older, the urgent need for intervention is clear.
