In Auburn’s active commercial settings, HVAC systems play a crucial role in maintaining comfortable indoor temperatures and clean air. However, over time, dirt, dust, and debris can build up on the system’s coils, reducing efficiency and increasing energy costs. That’s why professional cleaning is so important. At Auburn Air Duct Cleaning, we deliver comprehensive commercial coil cleaning services designed to optimize system performance, boost energy savings, and prolong the life of your HVAC equipment. Knowing the process behind this service helps your business make informed maintenance choices and avoid costly issues through regular commercial coil cleaning.

Why Clean Coils Matter in Commercial Buildings

Coils are the heart of your HVAC system. The evaporator coil cools the air, and the condenser coil releases heat outside. When these coils get dirty, they struggle to do their jobs efficiently. This causes your system to work harder, use more energy, and wear out faster.


Key benefits of clean coils include:

  • Lower utility bills

  • Improved indoor air quality

  • Longer HVAC system lifespan

  • Fewer repair calls and less downtime

  • Compliance with health and safety standards


The Coil Cleaning Process: Step-by-Step

Professional coil cleaning involves a detailed process tailored to your HVAC system’s needs. Here's a breakdown of what typically happens during a commercial coil cleaning service:

Step Description
1. System Evaluation Technicians inspect coil type, size, access, and level of dirt.
2. Power Off Power to the unit is shut off to ensure technician safety.
3. Dry Cleaning Loose dirt is removed using brushes, vacuums, or compressed air.
4. Apply Coil Cleaner A safe, non-corrosive solution is applied to dissolve grease, dust, and grime.
5. Soak Time The cleaner sits for several minutes to break down buildup.
6. Rinse or Wipe Coils are rinsed using low-pressure water or wiped clean, depending on system design.
7. Drying Coils are air-dried or dried using a blower.
8. System Restart & Test Technicians restore power, check airflow, and confirm proper operation.

This process ensures that coils are fully cleaned without damaging sensitive components.

“Clean coils aren’t just about better airflow—they’re about saving energy and preventing major HVAC problems before they start.”


When Should Coils Be Cleaned?

Most commercial HVAC systems should have their coils cleaned at least once a year. However, if your business operates in a high-dust environment (like warehouses, restaurants, or manufacturing plants), cleaning may be needed every 3 to 6 months.

Tip: Have your system inspected regularly to catch buildup before it becomes a problem.


Why Hire Professionals?

While DIY maintenance can help in some cases, coil cleaning is not one of them. Commercial HVAC systems are complex, and improper cleaning methods can cause damage or reduce system efficiency. Professionals use the right tools, cleaning agents, and safety protocols to ensure thorough, safe service.


Professional coil cleaning includes:

  • Non-damaging cleaning methods

  • Specialized coil-safe solutions

  • Efficient, mess-free service

  • Safety compliance

  • Expertise with various HVAC system brands
