Preventing A Freon Leak

When your AC repair man tells you that you have a Freon leak you can almost certainly say RIP to your air conditioner. A Freon leak in the HVAC world is comparable to terminal cancer you can keep spending money on Freon to keep your AC going but eventually your air conditioner will pass away. The Evaporator Coil is without a doubt the most common place to develop a Freon leak. Your Evaporator Coil is located in the indoor unit aka the air handler. The purpose of Your Evaporator Coil is to change your Freon from liquid to gas and then your blower fan will spread that cold temperature throughout the home. The cooling process creates condensation on the coils thus causing them to rust out and develop a Freon leak. Today I’m going to share a secret with you to stop or prevent this from happening to your AC or furnace.

  1. More great information! This makes sense, and I would assume that this will help prolong the life of the HVAC unit? Are the aluminum fins right there with the coils? Is it okay to get spray on anything but the fins? I ask this because it is a spray. Is this used only when you start to see rust, or can it be used as a preventative, while the HVAC still looks in good condition.

  2. This is a great tip! I am always looking for cheap easy prevention for expensive systems. The copper is definitely the weakest link in the system. What a great Fix
