Texas couple dies in their home after air conditioning breaks during intense heat wave

• A Texas woman says her parents were found dead after their air conditioner broke during a heat wave.
• Roxana Floods said air-conditioning companies should "warn people about how lethal this heat is."

The daughter of a Texas couple who died from extreme heat says air-conditioning companies should warn people about the dangers of staying inside hot homes.

Ramona and Monway Ison were found dead in their mobile home in Baytown, a suburb of Houston, Texas, on June 16, their daughter told Insider's Chris Panella. Houston also had its first excessive-heat warning since 2016 on June 16, as the heat wave in the southeastern US descended, according to Houston Public Media.

The Houston region is currently under an excessive-heat warning from the National Weather Service. The agency told residents that temperatures could get as high as 105 degrees Fahrenheit on Sunday.

The NWS said the "extreme heat and humidity will significantly increase the potential for heat-related illnesses."

At least seven people have died in Harris County, Texas, from heat-related illness since June, KTRK reported.

Roxana Floods, the couple's daughter, told Panella that her parents' air conditioner broke on June 12 and that they had spent the week securing a loan because they didn't have the money to fix it.

Floods said her parents — who grew up without air conditioning — scheduled the repair for June 16 and purchased fans because they thought "it would be OK."

"I would love for something to be set up with these large (air conditioning) companies to warn people about how lethal this heat is," she told KTRK. "If they don't have the money to get their air conditioner fixed, to let them know that they're literally staying inside an oven."

A county medical examiner declared the couple dead in the home as a repair technician pulled into the driveway on June 16, KTRK reported.

"They were gathering their things to leave," Floods told the outlet. "The way that they were found, I think they decided that it was too hot and it was time to go, and it was just too late."
