A simple mix of vinegar and water is one of the safest and most effective homemade AC coil cleaners
For tougher buildup, baking soda, dish soap, or diluted hydrogen peroxide can help clean coils
without damaging your unit. I think I messed up my AC until I learned this one easy trick
Turns out, a few household ingredients keep coils working like new, no expensive chemicals required
Coils get dirty from dust, pet hair, pollen, even grease. And that grime chokes airflow, cuts efficiency, raises your energy bills, causes nasty odors
Here's what works. Vinegar and water for maintenance. Dish soap plus baking soda for grease
Diluted hydrogen peroxide for mildew. Bleach only for heavy mold with ventilation
Clean both outdoor condenser coils and indoor evaporator coils when accessible. Use a spray bottle, gentle brushing, rinse lightly, never soak electrical parts
DIY is fine if coils are reachable and the power's off. Call a pro for sealed units, heavy mold, corrosion, or if you're unsure
Practical takeaway. Clean coils every 3 to 6 months. Always shut off power first
stick to gentle cleaners to protect your AC. Simple household ingredients can keep your AC
running cleaner, cooler, and more efficiently
