You Deserve a Comfortable, Cool Home – But Dirty AC Coils Might Be Standing in Your Way
In Las Vegas, where the summer heat can feel relentless, your air conditioner isn’t a luxury—it’s a necessity. But even the most powerful AC units can’t keep up when their internal components aren’t functioning properly. One hidden culprit that often flies under the radar? Dirty AC coils.
At Duct-Pro, we know how important a well-functioning HVAC system is to your comfort and peace of mind. Let’s break down how to tell when your AC coils are dirty, why it matters, and what you should do about it—so you can stay cool and worry-free all year long.
What Are AC Coils, and Why Do They Matter?
Your air conditioning system has two types of coils: the evaporator coil (typically located inside your indoor unit) and the condenser coil (in your outdoor unit). These coils are responsible for absorbing heat from inside your home and releasing it outside. When they get dirty, their ability to transfer heat is dramatically reduced, and your AC unit has to work much harder to keep your home cool.
Think of coils like the lungs of your system—if they’re clogged or congested, everything slows down and suffers.
How to Spot Dirty AC Coils
The good news is that dirty coils leave clues. If you know what to look for, you can catch the problem before it becomes a costly repair. According to our friends at Robert B. Payne, here are the most common signs:
1. Your Energy Bills Are Climbing
If your energy usage hasn’t changed but your power bills are getting higher, your AC might be running longer to achieve the same results, often due to dirty coils reducing its efficiency.
2. Your Home Isn’t Cooling Properly
Are certain rooms warmer than others? Does it seem like your AC just isn’t getting the job done? Reduced cooling performance is a key sign your coils may need attention.
3. Your System Runs Constantly
When coils are covered in dirt or debris, heat transfer slows down. As a result, your system may run for much longer periods in an attempt to cool your home.
4. Visible Dirt or Frost on the Coils
If you peek into your indoor or outdoor unit and see a buildup of dirt, dust, or even frost on the coils, that’s a clear sign they’re dirty. Warning: Do not attempt to clean them yourself unless you’re experienced—coil fins are delicate and easily damaged.
5. Unpleasant Odors
Dirty coils can trap moisture, which encourages mold and mildew growth. If you’re noticing musty smells when your system runs, dirty coils could be the culprit.
What Causes AC Coils to Get Dirty in Las Vegas?
Las Vegas is a unique environment. With its dry desert air, dust and debris are everywhere—and they love to stick to your HVAC components. Pet hair, pollen, and even smoke from seasonal wildfires can also build up over time.
Additionally, because our AC systems work overtime for much of the year, the wear and tear is more intense than in cooler climates.
What to Do About Dirty Coils
Once you suspect or confirm that your coils are dirty, the next step is critical—don’t ignore it. Running your AC with dirty coils can lead to:
- System overheating
- Compressor failure
- Sky-high energy bills
- Shortened equipment lifespan
Here’s what we recommend:
Step 1: Schedule a Professional Inspection
DIY maintenance has its place, but coil cleaning should be left to the pros. At Duct-Pro, we use specialized tools and cleaners designed specifically for delicate AC coils. We also inspect your entire system to ensure there are no other issues lurking beneath the surface.
Step 2: Invest in Regular Maintenance
In Las Vegas, AC systems need love all year long. We offer affordable maintenance plans that include:
- Coil cleaning
- Filter replacement
- Airflow testing
- Full system inspections
This proactive approach helps prevent problems before they start—and keeps your system operating at peak efficiency.
Step 3: Replace Filters Regularly
Dirty air filters lead to dirty coils. We recommend checking your filters monthly and replacing them every 1–3 months, depending on usage and whether you have pets, allergies, or high dust levels.
Step 4: Keep the Area Around Your Outdoor Unit Clear
Trim bushes, sweep away debris, and avoid stacking anything near your condenser unit. Good airflow is key to keeping your coils clean and efficient.
Step 5: Know When It’s Time to Upgrade
If your system is over 10–15 years old and struggling despite regular cleanings, it may be time to consider an upgrade. We can help you choose a modern, energy-efficient unit that’s sized right for your home—and offer guidance on rebates or financing if needed.
