With summer at our doorstep and extreme heat becoming a growing public health concern in Arizona, Cool Relief Rentals, a female-owned company founded by a mother/daughter duo, Hannah Perrine and Elizabeth Hillestad is launching today. The company provides same-day delivery of portable air conditioning units to keep Phoenix area families and pets safe and cool during almost inevitable air conditioning breakdowns.

"I've learned that extreme heat isn't just uncomfortable—it's life-threatening," said Hannah Perrine, Founder and CEO of Cool Relief Rentals. "Ahead of what is expected to be another scorching summer, we are thrilled to launch our new company and are also eager to help our community. As we get off the ground, we intend to take steps towards helping vulnerable residents get the relief they need to stay safe and healthy."
In tandem with its launch, Cool Relief Rentals is creating a community outreach initiative dubbed "Cool Homes, Safe Lives," which aims to provide relief to the city's most vulnerable populations, including seniors, children, and individuals without access to functioning cooling systems. "We will be donating portable AC units to be distributed through partnerships with organizations working to assist residents in need deal with heat relief," Perrine explained.
In 2024, there were 602 heat related deaths in Maricopa County. While most occurred outdoors, of those that occurred indoors, 70% were in homes where air conditioning systems were present, but non-functional.
