The generator is powering his father's oxygen machine.
"We have to have a generator. There's no choice. We bought a brand new generator just for this reason for emergency purposes," said Garcia.
But Garcia isn't alone. People in search of generators and propane tanks lined up outside of home improvement stores as they are desperate to find warmth.
"It was close to freezing this morning, then we got the space heater going so it warmed it up a bit," said one shopper.

With more people in the dark and looking for ways to stay warm, hospitals have been busy. Memorial Hermann at the Texas Medical Center alone has treated 60 patients for carbon monoxide poisoning. ABC13 has learned 100 patients total in the TMC were treated for the poisoning.
"It's a completely odorless gas. You can't see it. You can't smell it. You have no idea that you're inhaling it and getting poisoned," said Dr. Samuel Prater at Memorial Hermann/UTHealth.
Doctors say if you're running your car for heat, you should only do that outdoors, never in a garage. Even with the door open, dangerous fumes can penetrate your home. Symptoms of carbon monoxide poisoning include headache, nausea, and even problems with vision.

"The therapy for carbon monoxide is high levels of oxygen, right. We have plenty of oxygen in the hospital to deliver that, and a certain number of patients are going to need what's called hyperbaric oxygen, which is oxygen delivered at really elevated levels of atmospheric pressure," said Prater.
As for Garcia, he plans to keep making more trips to the pump for as long as he needs.
"If the generator stops working, I have enough oxygen back up. I have enough containers to keep him going," he said.
