Stay Cool: Top 10 Air Conditioning Problems

A functioning air conditioner is essential during a typical summer in Des Moines. When temperatures rise and humidity levels climb, your AC system becomes more than a comfort feature. It helps protect your health, keeps your indoor air safe, and makes day-to-day life bearable. 

That’s why AC problems are more than just an inconvenience. The good news is that most issues are common and can be addressed with timely maintenance or repair. In this post, we’ll cover the ten most frequent AC problems homeowners in Des Moines encounter, along with tips on when to call in for professional help. Schaal has been helping Iowa families stay cool for over 70 years, and we’re here when your system needs attention. 

The Top 10 Air Conditioning Problems Des Moines Homeowners Face

1. No Cool Air
   Your system runs, but the air coming out of the vents isn’t cold. This can be caused by low refrigerant levels, compressor failure, or electrical issues. It’s one of the most noticeable problems and becomes urgent during the peak of summer heat.

2. Weak Airflow
   If the air feels weak or uneven from room to room, the cause could be a clogged filter, blocked vents, ductwork leaks, or a malfunctioning fan. Poor airflow affects comfort and makes the system work harder than it should.
    
3. Strange Noises
   Banging, buzzing, or high-pitched squealing sounds usually mean something is wrong inside the unit. Loose components, failing motors, or worn-out belts are common culprits. These noises should not be ignored, as they often lead to bigger and more expensive repairs.

4. Unit Cycles On and Off Frequently
   Short cycling wastes energy and wears out your system. It can be caused by refrigerant issues, dirty coils, or an incorrectly sized unit. In addition to affecting performance, this problem drives up energy bills and reduces system lifespan.

5. Frozen Evaporator Coil
   Restricted airflow or low refrigerant can cause the evaporator coil to freeze. You might notice ice on the unit or reduced cooling performance. This issue requires professional attention to avoid long-term damage to your system.

6. Water Leaks
   If you see water pooling around your indoor unit, it’s likely a clogged condensate drain line. While this might seem minor, water leaks can lead to structural damage, mold growth, and costly home repairs if left untreated.

7. Thermostat Issues
   When your thermostat is inaccurate or unresponsive, it can be due to calibration problems, wiring issues, or a failing sensor. This affects your ability to control indoor temperature and often results in uneven cooling.

8. Unpleasant Odors
   A musty or foul smell from the vents may point to mold inside the unit or ductwork. It can also result from a dirty filter or accumulated debris. Besides being unpleasant, bad odors can affect your home’s air quality and should be addressed promptly.

9. High Energy Bills
   A sudden spike in your energy bill could be the result of an inefficient system. Dirty coils, duct leaks, thermostat problems, or aging equipment all contribute to reduced efficiency. Catching and fixing these problems early helps keep utility costs under control.

10. Unit Will Not Turn On
    If your AC won’t start, first check the thermostat settings and the circuit breaker. If those are in order, the issue could involve the motor, wiring, or electrical board. When basic troubleshooting doesn’t work, it’s time to call a licensed technician. 

Prevention is Key: Tips for Maintaining Your AC 

While some AC problems are unavoidable, many can be prevented with routine maintenance. These simple steps can help keep your system running smoothly: 

• Replace your air filter regularly. In Des Moines, dust and pollen levels can be high, so monthly checks are a good idea during heavy-use seasons. 

• Keep the outdoor unit clear of leaves, grass clippings, and debris to maintain airflow. 

• Make sure vents are not blocked by furniture or curtains. 

• Schedule professional AC maintenance at least once a year. A trained technician can clean the system, check refrigerant levels, inspect components, and identify early signs of wear. 

Preventive care is the best way to reduce the chance of emergency breakdowns during the hottest days of the year.
