When the Heat Hits Hard: What to Do If Your A/C Stops Working During a Heatwave

It’s 94 degrees in the shade, your dog has claimed the spot directly in front of the fan, and your popsicles are melting faster than your patience. Then it happens. your A/C taps out. Of course it picks the hottest day of the summer to do it.

Don’t panic. Before you start building a personal ice fort or threatening to move to Antarctica, here’s what you should do if your air conditioner quits during a brutal Iowa heatwave.

Is It Really Broken? Or Just Throwing a Little Tantrum?

First things first: check the basics. Sometimes it’s not a total system failure. it’s just a small issue that’s easy to fix.

  • Thermostat settings: Is it on “cool”? Is the battery dead?

  • Circuit breaker: Flip it. Just like your mood.

  • Air filter: A clogged filter can choke the system.

  • Outside unit: Make sure it’s clear of debris and hasn’t been turned into a bird condo.

If everything looks right and it still isn’t blowing cold air, it’s time to bring in the pros.

Keep It Cool…Without the A/C

While you’re waiting for help from Obsidian Heating & Cooling, here are some survival tips:

  • Close the blinds to block out that relentless Iowa sun.

  • Turn on fans to keep the air moving (and point one directly at your face. we won’t judge).

  • Stay downstairs—heat rises, and your basement just became the most luxurious room in the house.

  • Limit appliances—don’t add heat from ovens, dryers, or hair dryers. (Sorry, your blowout will have to wait.)

Final Tip: Don’t Wait for a Heatwave to Think About Your A/C
