Tuesday, the tri-states experienced its hottest day of the year so far.
In some places it even hit 90 degrees.
And that meant a lot of you turned on the A/C, but what if it isn't working?
Officials say the first thing you should do this time of year is to check your air filter.
If yours is dirty you should replace it to help your A/C run more efficiently.
Another tip experts say to do is to spray down your air conditioning unit with a hose to make sure it isn't clogged inside.
Officials say they also recommend getting your air checked professionally to prevent future problems when it's running a lot in the summer.
"Often times if you do preventative maintenance, we come out we look at all your electrical systems, make sure the contractors are good, check all your wiring, make sure everything is running properly," said Peters Heating and Air Conditioning Service Technician Bill Boren.
Boren says you shouldn't try to open the air conditioning unit yourself because it can be dangerous if you don't know what you're doing.
Boren says you should just call a professional if it isn't working.
