Investigators are still trying to determine if it was a surge or a lightning strike that struck a Davie home Sunday.
"We heard this really really loud clap of thunder," neighbor Tania Russell said. "Like there was no gap between when the thunder struck and the lightning hit."
Russell and her brother woke up to the sound of their neighbors calling 911.
"I just heard her screaming to someone, you need to call the police because my AC is on fire," Russell said.
Myles Russell spotted the owner of the house standing outside, and he says was covered in black soot.
Davie Fire Rescue responded to the home at 6924 Southwest 148 Lane within minutes of the call and found the master bedroom covered in heavy black smoke.
"There was a thunderstorm present during the time of the incident," said Davie Fire Rescue Batallion Chief Andy Popick. "They did have their lights flicker, so it's possible there was a lightning strike either direct or indirect."
Officials confirm one adult was transported to the hospital, and neighbors say the man is getting treated for smoke inhalation.
According to Davie Fire Rescue, the homeowners called 911 quickly, an important step to take if you think your house is struck by lightning. The batallion chief also says stepping outside of your home is necessary to avoid tragedy.
"The quicker we get here should there be a fire, the quicker we can extinguish it and get it out and that minimizes both property damage and potential injuries to civilians," Popick said.
