What is involved in AC coil cleaning?

Sure, I can help with that! When it comes to AC coil cleaning, think of it like giving your AC system a much-needed spa day. At IROB-Tech LLC, we start by inspecting your unit to assess the level of dirt and grime buildup on the coils. Then, we carefully remove any debris, dust, or mold that may be hindering your system’s efficiency. This process not only helps your AC run more smoothly but also improves indoor air quality. Plus, it can extend the lifespan of your AC unit, saving you money in the long run.

The Basics of AC Coil Cleaning

The basics of AC coil cleaning involve understanding common HVAC evaporator coil problems like dirt buildup, which can hinder cooling efficiency. Diagnosis and repair services, such as those provided by Audra Ln, are crucial for addressing issues like frozen coils, reduced airflow, or leaks that may arise due to neglected maintenance. Regular coil cleaning and professional HVAC services ensure optimal performance, prevent costly repairs, and extend the lifespan of your air conditioning system.

First things first, what are these coils we’re talking about? In an air conditioning system, you have two main types of coils: the evaporator coil and the condenser coil. Both play crucial roles in the cooling process, but over time, they can get dirty and affect your AC’s performance.

The Evaporator Coil

The evaporator coil is located inside your home, usually near the air handler or furnace. Its job is to absorb heat from the indoor air, cooling it down before circulating it back into your living spaces. As air passes over the coil, moisture in the air condenses on the coil’s surface, which is then drained away.

The Condenser Coil

On the flip side, the condenser coil is situated outside your home within the outdoor unit of your AC system. This coil releases the heat absorbed from inside your home into the outdoor air. It works in conjunction with the compressor and the refrigerant to complete the cooling cycle.

Why Clean AC Coils?

Now, you might be wondering, why bother cleaning these coils? Well, here’s the deal: over time, dirt, dust, pollen, and other debris can accumulate on the coils. This buildup acts as a barrier, hindering the transfer of heat. As a result, your AC works harder to achieve the desired cooling effect, leading to increased energy consumption and potentially higher utility bills.

Moreover, dirty coils can also impact indoor air quality. When air passes over dirty coils, it may pick up contaminants, allergens, and even mold spores, which then get circulated throughout your home. This can exacerbate respiratory issues and create an uncomfortable living environment.

Signs Your AC Coils Need Cleaning

Signs that your AC coils need cleaning include reduced cooling efficiency, higher energy bills, visible dirt buildup on the outdoor unit’s condenser coil, strange odors from vents indicating mold or mildew, and ice formation on the evaporator coil due to restricted airflow. For thorough cleaning and maintenance, consider professional air conditioning services like those provided by companies such as IROB-Tech LLC, ensuring optimal performance and longevity of your AC system.

How do you know when it’s time to clean your AC coils? Here are some telltale signs to watch out for:

Reduced Cooling Efficiency: 

If you notice that your AC isn’t cooling your home as effectively as before, dirty coils could be the culprit.

Higher Energy Bills: 

A sudden spike in your energy bills without a corresponding increase in usage could indicate that your AC is working harder due to dirty coils.

Visible Dirt Buildup: 

Take a peek at your outdoor unit. If you see visible dirt, debris, or plant growth on the condenser coil, it’s time for a cleaning.

Strange Odors: 

Foul or musty odors coming from your vents could be a sign of mold or mildew growth on the evaporator coil.

Ice Formation: 

If you notice ice forming on the evaporator coil, it could be due to restricted airflow caused by dirt buildup.

DIY vs. Professional Cleaning

When it comes to AC coil cleaning, DIY methods may seem cost-effective, but they carry risks like damaging sensitive components and limited effectiveness. Professional HVAC services, like those offered by IROB-Tech LLC, ensure expert handling, specialized tools for thorough cleaning, and comprehensive system checks. While professional cleaning may be costlier, it’s an investment in improved AC performance, energy efficiency, and long-term savings on potential repairs or replacements.

Now, you might be tempted to grab some cleaning supplies and tackle the job yourself. While DIY cleaning is possible, it’s essential to proceed with caution, especially if you’re not familiar with HVAC systems. Here’s a comparison of DIY and professional AC coil cleaning:

DIY Cleaning


  • Cost-effective if you already have the necessary tools and cleaning agents.
  • Can be done on your schedule without waiting for a service appointment.


  • Risk of damaging sensitive components if not done correctly.
  • Limited effectiveness compared to professional cleaning.
  • Safety concerns, especially when dealing with electrical components and refrigerants.

Professional Cleaning (IROB-Tech LLC, for example)


  • Expertise and experience in handling AC systems, ensuring thorough and safe cleaning.
  • Specialized tools and equipment for effective coil cleaning.
  • Comprehensive inspection of other AC components for potential issues.


  • Costlier than DIY, but the investment can pay off in improved AC performance and longevity.
