Imagine you’re feeling the heat of summer, and you’ve turned on your A/C, but it’s not working properly. You’ve checked the filter, and it’s clean, but you still can’t figure out why the air isn’t cold. One of the most common causes of this issue is dirty A/C coils.

Over time, dirt, dust, and other debris can accumulate on the coils, making it difficult for them to function correctly. This, in turn, can lead to reduced efficiency and increased energy consumption, resulting in higher electricity bills.

  • A/C coil cleaner
  • Gloves
  • Safety glasses
  • A stiff-bristled brush
