So how many times have I heard this phrase this year. Or “I just have my AC guy top off my air conditioner every year with about a pound of Freon”. Well I have heard that over and over. One homeowner even boasted he was an engineer telling me that it was just a pinhole leak and his power bills have been constant over the last 5 years. That is highly doubtful and even if true does not take into account scientific results of other environmental factors preventing a proven cause-effect relationship. He didn’t want to listen when I explained that leaks get worse over time. So if you are reading this dude, get a grip. If you are a good engineer, then you should know that you need data to back up your obviously emotional claim.
Here is an article that highlights a scientific study by the Trane Corporation that found the root cause for most copper coil leaks: Formic Acid. And yes, Virginia, there is a Santa Clause, and the leak does get worse over time.
In this article it explains that formic acid is etching the copper coils creating those pinhole leaks and that they continue to grow with time. There is no one solution to these leaks, but rather points to the new industry initiatives to replace copper coils with aluminum coils. Replacing the coil is the only 100% sure fire solution to fix a leak. However it is expensive. And for some people, if there are less costly alternatives, then they want to be presented with them so they can delay the replacement until they can raise the funds.
Some leak seal treatments address this erosion problem without creating a risk to the major motors and valves. However other leak stop products are more of a jell that can coagulate on the motors and valves creating further damage to the system.

Time for your Air Conditioner Tune Up

Why You Need an Air Conditioner Tune-up
It is springtime again in Raleigh North Carolina and people are just now starting to turn on their air conditioners for the first time. Most air conditioners have been sitting idle through the winter and probably have not been checked for several months. Through the winter, the condensing units have been exposed to adverse weather conditions, clumsy landscapers, dust and pollen, dirt from construction sites, road salts from the traffic, dirty air filters, and much more. All these environmental conditions have a significant impact on the operation and life of your equipment.
The #1 cause for air conditioner failures is compressor burn out. All the dirt, pollen, dust, leaves, and landscaping mulch can build up on the outside coils and cause the compressor to overheat. When a compressor operates at elevated temperatures, the oils inside begin to breakdown and stop lubricating the compressor parts. Then the friction build up elevates the temperatures even more and soon your compressor will stop functioning.
