Why is my Air Conditioner running Constantly?

There is nothing worse than being stuck in warm, humid house with no air flow during a hot summer day in Eastern Iowa. You find yourself sweating and uncomfortable. It’s like you’re trapped in a giant sauna.

Let’s take a look at a few common causes behind why your air conditioner may be running non-stop. This may be an early indication your system is on it’s way out and buys you a little time to make a decision on replacement or repair.

Your Air Conditioner is Aged and Needs Replaced

Is your unit over 14 years old? Air Conditioners have lifespans, just like any other appliance. Even with our trained technicians cleaning and checking the unit annually, they will eventually wear out.

If you do have to replace your unit, there are rebates available through your electric provider. Check out Alliant Energy’s rebates. These rebates are available upon completion of the SAVE test, conducted by our technicians, on your system. The rebates vary from the SEER ratings on the systems.

Check Your Air Filter

When was the last time you replaced your air filter? A dirty air filter can make your air conditioner work harder than usual.

One of the most common reasons HVAC systems break down is due to a dirty filter. It’s important to change the filters regularly to avoid overworking your system. If you have pets, check the filter more often.

Is Your Air Conditioner Dirty?

As part of a spring cleaning, make sure the coils in your AC unit are clean. Sometimes they can collect debris and reduce air flow resulting in poor performance. Your condenser coils need to be cleaned after being exposed to the elements. We recommend simply spraying the coils with a garden hose after turning off electrical power to the unit. We also recommend a professional clean and check to make sure everything is ready for the warm summer ahead.


It’s important to address any AC issues before they become major problems. An overworked air conditioner can be very costly in your utility bills.
