In this heat, chances are your air conditioning unit has been working overtime all day.
We reached out to the experts for some advice on ways to make sure your air conditioning stays up and running.
"In severe temperatures, a typical air conditioner capacity will be cut in half," said Ken Goodrich, the owner of Goettl Air Conditioning. "A four-ton air conditioner will be running like a two-ton air conditioner."
Goodrich advises checking air filters once a month to make sure they're clean.
Technicians also recommend annual tune-ups.
Other tips include keeping the area around the units clear of leaves and other debris.
If cooling stops working, Goodrich says the first thing to do is check the circuit breakers. He suggests turning them off somewhat forcefully, then switching them back on.
Don't leave the AC on. If it's broken, turn it off.
At this time of year, it could be a while until technicians are available to come fix broken units.
