Heat Pump Inspection & Testing in Des Moines Metro

Is Your Heat Pump Just Not Keeping Up Anymore?

Is your heat pump suddenly making a grinding or hissing noise you’ve never heard before, or are your utility bills climbing for no good reason? These are clear signs that something is wrong internally, and ignoring them almost always leads to a bigger, more expensive failure. Midwest Comfort Heating & Cooling has technicians on the road right now across the Des Moines Metro, ready to perform a full inspection and find the real source of the problem.

Warning Signs Your Heat Pump Needs an Inspection

Uneven Heating or Cooling

You shouldn't have hot and cold spots in your house. If one room feels like a sauna while another is an icebox, your system is struggling to distribute air correctly. This often points to an issue with refrigerant levels, airflow, or the reversing valve that switches between heating and cooling.

Strange Noises or Odors

Your heat pump should be relatively quiet. Grinding, squealing, or loud buzzing sounds are mechanical red flags that mean parts are failing, usually motor bearings or the compressor. A musty smell can indicate mold on the indoor coil, while a burning odor points to a serious electrical problem that needs immediate attention.

Skyrocketing Energy Bills

A sudden, unexplained jump in your monthly energy costs is one of the most common signs of a heat pump in distress. It means the unit is working much harder than it should to do its job, burning through electricity to compensate for an internal issue. This could be anything from low refrigerant to a dirty coil, but it's never normal.

Frequent On-and-Off Cycling

Does it feel like your system turns on for a few minutes, shuts off, and then kicks back on again a short time later? This is called short cycling, and it puts tremendous strain on the compressor, the most expensive part of your unit. It’s a major cause of premature system failure and needs to be diagnosed properly.

Weak or Insufficient Airflow

When you put your hand up to a vent, the airflow should feel strong and consistent. If it feels weak, or if the air isn't as warm or cool as it should be, something is restricting the system. This is often a clogged filter or a dirty coil, but it can also signal a failing blower motor.

Common Causes of Heat Pump Performance Issues

Refrigerant Leaks

Refrigerant is the substance that actually moves heat in and out of your home. Over time, vibrations and corrosion can create tiny pinhole leaks in the copper lines. When the refrigerant level drops, your system loses its ability to heat or cool effectively, forcing it to run constantly without ever reaching the set temperature.

Dirty Coils and Clogged Filters

Your heat pump has two coils—one inside and one outside—that are essential for heat transfer. When they get caked in dirt, dust, and grass clippings, they can't do their job. This insulating layer of grime forces the system to work harder, reduces efficiency, and can lead to the unit freezing up or overheating.

Electrical Component Failure

A heat pump relies on a series of electrical parts like capacitors and contactors to start the motors and run the compressor. These components wear out over time or can be damaged by power surges. A single failed capacitor can prevent your entire system from starting, even if all the mechanical parts are fine.

Blower Motor and Fan Problems

The indoor blower motor is responsible for pushing conditioned air through your ducts, while the outdoor fan pulls air across the condenser coil. If either of these motors fails or their bearings wear out, airflow will be severely compromised. This leads to poor performance, strange noises, and can cause the compressor to overheat.

What to Expect During Your Heat Pump Inspection & Testing Visit

When we show up for an inspection and testing call in the Des Moines Metro, our first job is to listen—both to you and to the system itself. We’ll ask what you’ve been noticing and then run the unit through its paces, checking for the obvious signs of trouble. This isn't just a quick look; it's a deep-dive diagnostic to find the root cause, not just the symptom.

Our technician will connect gauges to measure the refrigerant pressure, which tells us if the system is properly charged and if there might be a leak. We’ll thoroughly inspect the indoor and outdoor coils for dirt and blockages that kill efficiency. We test the electrical components, including capacitors and contactors, to make sure they're providing the correct voltage and not on the verge of failure.

Finally, we check airflow, measure the temperature of the air coming out of your vents, and verify the thermostat is communicating correctly. At the end of the visit, you’ll get a clear, no-nonsense explanation of what we found, what needs to be fixed, and what your options are. We're here to give you the information you need to make the right decision for your home.
