"We've been extremely busy," technician Jeff Monackey said. "We try to get to people who are elderly or who have children or who have one unit first."
Over the last few days, calls for service on home air conditioning units jumped 50 percent for Newcomb and Company.
Monackey says homeowners should have annual maintenance checks, change filters often and keep the thermostat set at a warmer temperature.
"If it's hot outside you're not going to make it cool quicker by putting it down further," Monackey said. "Just remember 20 degrees from the outside temperature is what she's going to be able to handle."
Business is also heating up at auto shops.
"I was out running errands and I was looking forward to getting into my car and letting the AC blast and then when that stops working, you've got to get it fixed fast," driver Elyse Archer said.
With so many jobs, Duraleigh Auto Center had to hire another technician.
"Right now we have four AC jobs in the shop and more scheduled to come in," Duraleigh Auto Center Owner Gary Ingold said.
To avoid costly car repairs, auto experts recommend you get your AC recharged every year. They also say you should turn your AC off before you start your engine.
