Why Dirty AC Coils Are Costing You Money (and How to Fix It)

When was the last time you thought about your air conditioner’s coils? Probably not recently. But here’s the truth: dirty AC coils could be draining your wallet every single month. From higher energy bills to poor air quality, neglecting coil maintenance can have costly consequences. The good news? Fixing it is easier than you think.

In this guide, we’ll explain why clean coils matter, the most common problems caused by dirt and buildup, and how a foaming AC coil cleaner like Nu-Coil can restore your system’s efficiency in minutes.

 

 

 

Why AC Coils Get Dirty:

Your AC unit has two main types of coils:

• Evaporator coils (inside your home) absorb heat.
• Condenser coils (outside your home) release heat.

Over time, these coils collect dust, dirt, pet hair, pollen, and even mold. Because coils are constantly exposed to air and moisture, buildup happens fast especially in humid or dusty environments.

 

 

 

The Hidden Costs of Dirty Coils

 

If you skip coil maintenance, here’s what happens:

1. Higher Energy Bills
   Dirty coils force your AC to work harder, which means your unit consumes more electricity. According to the U.S. Department of Energy, dirty coils can increase energy consumption by up to 30%.
2. Shorter Equipment Lifespan
   When your system is constantly overworking, it puts extra strain on motors and compressors leading to costly repairs or premature breakdowns.
3. Poor Air Quality
   Dirt and mold on coils can circulate allergens, odors, and bacteria throughout your home. If you’ve noticed musty air, dirty coils could be the culprit.
4. Uneven Cooling
   Blocked coils can’t properly absorb or release heat, leaving you with hot spots in your home.

 

 

 

How to Fix It: The Power of a Foaming Coil Cleaner

Instead of calling an HVAC technician every time, you can clean coils yourself using a foaming AC coil cleaner like Nu-Coil.

 

Why Nu-Coil?

1.  Foaming action penetrates deep into coils, lifting dirt and grime.
2. Self-rinsing formula no need for complicated tools or heavy rinsing.
3. Improves airflow for better cooling performance.
4. Saves money by reducing energy consumption.

 

How to use Nu-Coil in 3 easy steps:

1. Turn off your AC unit. Safety first.
2. Spray Nu-Coil directly onto dirty coils. The thick foam expands to reach hidden buildup.
3. Let it work. The foam dissolves grime, then rinses away naturally with condensation.

That’s it no scrubbing required.

 

 

Pro HVAC Maintenance Tips

 

• Clean coils at least twice a year (before summer and winter).
• Change air filters every 1–3 months to prevent faster buildup.
• Keep outdoor condenser units free from leaves, grass, and debris.
• Pair Nu-Coil cleaning with regular professional inspections for best results.
