AC Inspection & Testing in Des Moines Metro

Not Cooling Like It Used To? We Find the Real Problem.

Is your air conditioner running constantly but the house never gets cool? Are you hearing new rattles, hisses, or grinding sounds from the unit outside? These are early warnings that something is wrong, and guessing at the cause can lead to a full breakdown on the hottest day of the year. Midwest Comfort Heating & Cooling has the diagnostic tools and experience to pinpoint the exact issue and give you straight answers.

Warning Signs Your AC Needs a Professional Inspection

When your system isn’t right, it sends signals. I’ve seen it hundreds of times across the Des Moines Metro—ignoring these signs almost always costs more in the long run. If you notice any of these, it’s time to get a professional set of eyes on it.

Weak or Uneven Airflow

You feel it right away—the air coming from your vents just doesn't have the force it used to, or some rooms are comfortable while others are stuffy and warm. This points directly to a restriction somewhere in the system. It could be a badly clogged filter, but more often it’s a dirty evaporator coil caked with dust and grime, or even issues within your ductwork.

Strange Noises from the Unit

Your AC should be a low, consistent hum, not a collection of clanks, squeals, and buzzes. A grinding or squealing noise often indicates a failing motor or worn-out bearings. Hissing is a classic sign of a refrigerant leak, and a loud buzzing or chattering usually points to an electrical problem with a contactor or capacitor.

Unpleasant Odors When the AC Kicks On

If you get a whiff of musty, dirty-sock-smelling air when the AC starts, you likely have mold or mildew growing on your indoor coil or in the drain pan. This is common with our humid Iowa summers and it’s terrible for your indoor air quality. A burning smell is more serious, signaling an overheating electrical component that needs immediate attention.

Higher-Than-Normal Energy Bills

Your utility bill is often the first sign of trouble. If your electricity costs have shot up without a change in your habits, your AC is working harder than it should to do its job. That inefficiency is a direct result of a problem like low refrigerant, dirty coils, or a struggling compressor.

Frequent Cycling or Constant Running

A healthy AC runs in predictable cycles to maintain the temperature on your thermostat. If your unit is turning on and off every few minutes (short cycling), it’s putting extreme wear on the compressor. If it runs for hours on end without ever shutting off, it can’t keep up and is fighting a losing battle against a bigger problem.

Common Causes We Uncover During an Inspection

After inspecting thousands of systems around Ankeny, we know the usual suspects. The problem is rarely what a homeowner first thinks. It’s usually one of these underlying issues that requires proper tools and experience to diagnose correctly.

Dirty Evaporator and Condenser Coils

The coils are where your system exchanges heat, and they have to be clean to work. Here in the Des Moines Metro, cottonwood fluff and dust can form a thick blanket on your outdoor condenser coil, choking it off. Inside, the evaporator coil gets clogged with household dust and pet dander, which turns to sludge in the humidity and blocks airflow.

Low Refrigerant Levels from Leaks

Refrigerant is not like gas in a car; it doesn't get "used up." If your system is low, you have a leak somewhere in the lines or coils. Just adding more refrigerant without finding and fixing the leak is a waste of your money and a temporary fix at best. We use electronic leak detectors to find the source so we can perform a permanent repair.

Failing Electrical Components

The capacitors, contactors, and relays are the brains and muscles of your AC. A failing capacitor can’t provide the jolt of electricity needed to start the compressor or fan motor, leading to a humming sound and no cooling. These parts wear out over time and from the stress of summer heat, and a simple test can tell us if they’re on their last legs.

Clogged Condensate Drain Line

Your AC pulls a lot of moisture out of the air, which collects and flows outside through a drain line. In our humid climate, that line can get clogged with algae and sludge, causing water to back up. This can trigger a safety switch that shuts your entire system down or, worse, cause the drain pan to overflow and damage your ceiling or furnace.

What to Expect During Our AC Inspection & Testing Visit

When you call us for an inspection, you're not getting a salesman—you're getting a technician. We show up to find the root cause of the problem, not to push a new unit. Our process is thorough because a misdiagnosis costs you time and money.

A technician from Midwest Comfort Heating & Cooling will connect gauges to your system to read the refrigerant pressures and temperatures, which tells us a huge story about its internal health. We’ll test the electrical components like capacitors and contactors to ensure they are within the manufacturer's specifications. We check airflow, inspect the indoor and outdoor coils for blockages, and verify the condensate drain is clear.

After our comprehensive testing, we’ll walk you through exactly what we found, showing you the readings and the problem areas on your system. We’ll explain your options clearly, whether it’s a straightforward repair or a more complex issue. You’ll get an honest assessment and an upfront price, with no pressure.
