After months of dust buildup, your evaporator coils may be covered in a layer of grime that reduces performance without obvious signs. At Edge Energy, we refer to this as the “invisible blanket.”
This buildup blocks heat absorption, leading to weak airflow, reduced cooling, and even system freeze-ups.
The Impact of Dirty Coils
Lukewarm Air from Vents
When coils are dirty, they can’t absorb heat effectively.
This results in warm air coming from your vents and increased energy usage as your system works harder to compensate.
When Your Unit Freezes
Restricted airflow can cause condensation to freeze on the coils.
This leads to ice buildup, reduced performance, and potential system shutdown.
Causes of Coil Clogging
Winter Dust Build-Up
Dust accumulates during winter months when systems are used less frequently.
Once cooling season begins, that buildup interferes with normal operation.
Grime as an Insulator
Dirt acts as insulation, trapping heat and reducing cooling efficiency.
This increases system strain and monthly energy costs.
Essential Maintenance Tips
Cleaning Tips for Coils
- Turn off power before cleaning
- Access coils through the panel
- Gently brush away debris
- Apply approved coil cleaner
Improve AC Efficiency
- Inspect system regularly
- Replace air filters
- Schedule professional maintenance
Keeping coils clean improves performance, reduces energy use, and extends system lifespan.
Edge Energy also helps homeowners take advantage of Efficiency Maine programs, making high-efficiency upgrades more affordable while improving long-term comfort.
