Is Your A/C Running Constantly? Here’s What It Means and What to Do About It
If you’ve been hearing your air conditioner humming nonstop this summer, you’re not alone. During Iowa’s steamiest July days, a hardworking A/C can feel like a blessing… until you realize it hasn’t stopped running for hours, and your energy bill starts sweating more than you are.
At Obsidian Heating & Cooling, we get calls like this all the time from our friends in Ankeny and across central Iowa. So, why does your A/C keep running, and what can you do about it?
Is It Normal for My A/C to Run Constantly in the Summer?
Sometimes, yes, especially during long stretches of 90+ degree days with high humidity. Your system might need to work overtime just to keep up. But if your A/C runs continuously even during milder days or fails to reach the set temperature, that’s a red flag.
Common Reasons Your A/C Won’t Quit
Let’s break down a few culprits behind that marathon-running unit:
1. Dirty Air Filter
A clogged filter restricts airflow, making your system work harder and longer. It’s like trying to breathe through a pillow.
Fix it: Check and replace your air filter every 1–3 months.
2. Thermostat Set Too Low
We get it, you want it chilly. But setting the thermostat to 65° when it’s 95° outside doesn’t cool your home faster, it just overworks your system.
Fix it: Aim for a moderate, consistent temp. 72–75° is a sweet spot for comfort and efficiency.
3. Refrigerant Issues
Low refrigerant means your system isn’t cooling properly, so it runs longer trying to do the job.
Fix it: This one’s not DIY. call Obsidian for a professional diagnosis and recharge if needed.
4. Poor Insulation or Air Leaks
Your cool air might be slipping right out through old windows, doors, or poor attic insulation, forcing your system to work overtime.
Fix it: Seal gaps, add insulation, and consider energy-efficient upgrades.
5. Your A/C Is Undersized (or Just Old)
If your unit’s too small for your home, or nearing the end of its lifespan, it might not be powerful enough to keep up, no matter how hard it tries.
Fix it: Let our team evaluate your system and recommend a right-sized replacement if needed.
