The surge in temperatures is leading to a flood of calls for local HVAC companies.

Gerard Depaoli, with GAD Air, says the HVAC company is booked more than a month out.

He says people don't want to wait.

However, many are waiting due to the increase in demand and lack of qualified people to do the work, which is adding to the backlog of jobs.

Depaoli says if your air conditioning breaks, there are some things to check before you pick up the phone and call an HVAC company.

"Check the batteries in your thermostat, make sure your filters been changed, make sure somebody didn't hit the switch," he says. "And don't go buy new furniture and block the return vent."

He says his team is working to get AC units up and running - and they know it's hard to be patient when you're sitting in the heat.

The CDC has some tips to help you stay healthy during the summer heat:

-Drink plenty of fluids

-Wear lightweight light-colored clothing

-Avoid hot and heavy meals - try opting for something light like a salad.
