Running a commercial building means keeping the HVAC system in top shape—and one part that often gets ignored is the coils. These components play a big role in how well your system works and how clean the air is inside your space. When coils get dirty, your HVAC has to work harder, your energy bills climb, and the air you’re breathing can become a problem. So commercial coil cleaning is important.
In cities like Philadelphia, where pollution and changing weather are part of everyday life, your HVAC system takes a beating. That’s why regular coil cleanings from trusted companies like Philadelphia Air Duct Cleaning are so important. Here’s why this simple service can make a big difference for your building and everyone in it.
What HVAC Coils Do
There are two main coils in any HVAC system: the evaporator and the condenser. They help with heating and cooling by moving heat in and out of the building. But over time, especially in busy buildings, they gather dust, mold, and other gunk that gets in the way.
What You’ll Find on Dirty Coils
| Type of Buildup | Health Impact | Where It Comes From |
|---|---|---|
| Dust | Breathing problems, allergies | Air recirculation |
| Mold | Respiratory issues, infections | Damp areas |
| Bacteria | Illness, bad odors | Organic buildup |
| Pollen | Allergy flare-ups | Outside air |
| Oil/Grease | Air pollution, sticky particles | Kitchens, machines |
Why Coil Cleaning Matters for Indoor Air
1. Stops Pollutants from Spreading
Air that moves across dirty coils picks up whatever’s stuck there. Once it gets into the vents, it goes everywhere. Cleaning the coils blocks this from happening.
2. Keeps Mold and Mildew Away
Moisture near the evaporator coil can create a mold hotspot. Cleaning it helps dry things out and keeps mold from forming in the first place.
3. Improves Air Movement
When airflow is blocked by dirt, your system can’t cool or heat properly. Cleaning the coils lets air move freely, making the whole space feel more comfortable.
4. Gets Rid of Funky Smells
Built-up grime can create unpleasant odors. A good cleaning clears out the source, leaving your indoor air fresher.
5. Helps the Entire HVAC System Run Better
Clean coils mean less stress on the rest of the system. Pair this with duct cleaning for even better air quality and system performance.
“If your coils are clogged, your whole building feels it. Clean coils keep the air moving and the people inside healthy.”
When It’s Time to Clean Your Coils
Keep an eye out for these signs:
- Energy costs going up with no clear reason
- Uneven temperatures from room to room
- Musty or stale smells coming from the vents
- Mold or dust buildup near HVAC units
- More people sneezing or coughing indoors
- The system shutting off and on too often
If you notice these things, it’s probably time to book a coil cleaning.
What It’ll Cost You
Costs depend on your HVAC size, how easy the coils are to reach, and how dirty they are. Here’s a rough estimate:
| Type of System | Estimated Cost per Unit |
|---|---|
| Small Rooftop Unit | $150–$300 |
| Medium HVAC Unit | $300–$600 |
| Large Coil System | $600–$1,200 |
Common Questions
How often should coils be cleaned?
Once a year is usually fine, but high-traffic or high-dust buildings may need cleanings every 3 to 6 months.
Can dirty coils cause health issues?
Yes. Coils covered in mold or bacteria can lead to breathing problems and allergies, especially in people with sensitivities.
Is coil cleaning the same as duct cleaning?
No. Coil cleaning targets the heat exchange components, while duct cleaning deals with the air pathways. They work best together.
What equipment do pros use?
Special tools like coil brushes, pressure washers, and eco-safe cleaners designed for HVAC systems.
Can I clean the coils myself?
You can do light surface cleaning, but for a deep and safe job, it’s best to leave it to trained technicians.
