Just used this 5-piece AC fin cleaning set on my ancient home unit, and wow – it’s like giving your AC a spa day! The 3 metal fin combs (green, red, yellow) tackled bent fins effortlessly, while the stiff white brush and foldable blue brush made dust vanish. My AC now blows colder air, and I swear it sounds happier.

PROS:

• Color-coded tools make selection idiot-proof (green comb = medium fins, red = large, etc.)

• Metal combs have perfect flex – straightens fins without snapping them

• Blue detail brush reaches nightmare corners behind condenser coils

• Saved me $200 vs. pro service call

CONS:

• Smallest comb (10 FPI) still too wide for ultra-fine LG unit fins

• Plastic handle on white brush feels cheap – might crack under heavy pressure

• No storage pouch (tools rattled loose in my toolbox)

BEST FOR: DIYers with older units (15+ yrs) or window ACs. Newer models with micro-fins may need specialty tools. Pro tip: Spray fins with coil cleaner first – the gunk wipes off like magic with the included brushes!
