Common AC Problems in Des Moines Homes | Lazer Home Services

Living in Des Moines, having a dependable air conditioning system isn’t a luxury, it’s a necessity. As the temperatures rise, homeowners depend on their AC units to keep homes cool, comfortable, and safe. But just like any mechanical system, air conditioners are prone to occasional problems.

If you’ve ever searched “AC not working in Des Moines” or “why is my air conditioner not cooling,” you’re not alone. At Lazer Home Services, we regularly respond to these common complaints and help local families restore comfort with fast, expert solutions. Whether it’s poor airflow, strange noises, or rising energy bills, most issues can be resolved with the right diagnosis and repair.

Let’s walk through the most common AC problems Des Moines residents face and how to fix them before they lead to bigger complications.

1. AC Not Blowing Cold Air: What’s Behind It?

One of the most frequent issues we handle is when the air conditioner runs but doesn’t cool the space. In Des Moines homes, this is usually tied to a few core problems: a clogged filter, low refrigerant levels, or a dirty evaporator coil.

When your AC isn’t blowing cold air, it may be due to restricted airflow or the inability to remove heat effectively. Dirty air filters limit circulation. Low refrigerant makes it impossible to absorb heat. And dust-covered coils reduce efficiency significantly.

Regular system care, like air conditioning maintenance, is the best way to prevent these issues. Our experts clean, inspect, and recharge your unit so it performs as expected throughout the season.

2. Thermostat Issues That Confuse Your System

Sometimes the problem isn’t your air conditioner it’s the thermostat. If your unit turns off before reaching the set temperature or won’t turn on at all, the issue could be related to wiring faults, low batteries, or miscalibration.

Thermostats are like the brain of your AC system. When they malfunction, your system gets the wrong instructions. In Des Moines, we frequently help homeowners upgrade to smart or programmable models to avoid unnecessary repairs and gain better temperature control.

If your current setup is unreliable, it might be time to request a thermostat evaluation as part of your next AC repair visit.

3. Unusual Noises from the AC Unit

Rattling, buzzing, banging, or hissing sounds aren’t just annoying, they’re warning signs. Noises coming from your air conditioner often mean that something is loose, damaged, or obstructed inside the unit.

A loud humming could point to an electrical issue. Clicking or popping noises may be linked to loose hardware. Hissing can indicate a refrigerant leak, which should be addressed immediately by an HVAC professional.

If you hear anything out of the ordinary, it’s best not to ignore it. Our team at Lazer  Home Services offers fast, detailed diagnostics to pinpoint the source of the sound and recommend the right fix. Learn more about our process on our About Us page.

4. Short Cycling and Constant Restarting

When your air conditioner frequently turns on and off in short bursts, it’s experiencing what’s known as short cycling. This is more than a nuisance; it wastes energy, reduces efficiency, and puts strain on key components like the compressor.

Short cycling may be caused by dirty filters, incorrect thermostat placement, oversized units, or electrical faults. Whatever the cause, it leads to poor cooling performance and higher utility bills for Des Moines homeowners.

Our AC technicians check for airflow restrictions, refrigerant levels, and electrical issues to bring your system back into normal operation.

5. Water Leaking Around the AC Unit

Moisture or water pooling around your AC unit is another common issue, particularly during peak cooling season in Des Moines. While condensation is normal, visible leaks usually point to blocked drain lines, frozen evaporator coils, or broken pump components.

Ignoring the issue can cause water damage to your floors, walls, or even electrical systems. At Lazer Home Services, we respond quickly to identify leaks and unclog lines or make drainage system repairs before they cause costly damage.

If your system is leaking, schedule a service call right away.

6. Rising Energy Bills Despite Normal Use

If your cooling costs are going up even though your usage hasn’t changed, your AC may be working harder than it should. Poor airflow, dirty filters, worn-out components, and lack of maintenance are all common reasons for this issue.

Even if your system seems to be working fine, inefficiency is a hidden problem that adds up fast. Des Moines homeowners can save significantly with seasonal maintenance services that include filter checks, coil cleaning, and performance testing.

It’s also a good time to review current offers that may help you reduce repair or upgrade costs.

7. Frozen Evaporator Coils: A Sign of Bigger Trouble

Frozen coils prevent your system from absorbing heat, which results in weak or no cooling output. This can happen due to restricted airflow, low refrigerant, or fan malfunctions.

If you see ice on your indoor unit or feel warm air blowing despite the system running, turn it off and call a professional. Continuing to run the unit in this condition may cause severe compressor damage.

Our certified technicians handle AC repairs safely and effectively, getting your home’s climate control back on track.

8. Old Systems That Need Constant Repairs

If your air conditioner is 10–15 years old and breaking down frequently, it might be time to consider a full replacement. Repeated repairs often cost more over time than a new unit and you still won’t get the comfort or efficiency of modern systems.

We help Des Moines homeowners evaluate when to repair and when to replace. If needed, we’ll provide recommendations and seamless installation through our air conditioning installation service.
