If your refrigerator more than a few years old, and especially if you have pets, chances are excellent that the condenser looks like this:
This isn’t insulation. It’s dust and lint and fur and anything else that landed on the floor and it’s very bad for your refrigerator.
It’s also very bad for your wallet.
A clogged condenser can easily raise your refrigerator’s electrical use by hundreds of dollars per year.
But it’s easily fixable!
I have a powerful vacuum cleaner with great filters, special nozzles and all the right tools to get into all the places dirt hides.
Your refrigerator will thank you and so will your wallet.
