To all home owners and DIY'ers. I'd like to take a moment to address the issue of trying to repair your home A/C system by yourself.
This message is for Homeowners and those who like to Do repairs themselves. Please don't try to repair your HVAC unit yourself. Most units are wired for 240 volts, and most fan speeds are in excess of a thousand revolutions per minute. Your A/C system has capicitors which store high voltage and can shock you, if touched. The fan blades in your unit are very sharp. An improperly repaired system may result in an electrical or complete unit failure. If wired incorrectly, your A/C system can cause a fire, and burn your home to the ground. The discharge pressures of R22 systems are over 200 pounds per square inch, and are extremely hot. The newer 410A system pressures are significantly higher by several hundred pounds per square inch. It takes many years of experience to learn about A/C systems, and new technology is introduced all the time. You can spend an entire lifetime, and not know all there is to know about HVAC. Some people post do it yourself questions here, and become frustrated that we won't answer them. The risk of injury to the home owner is so great, that we can't. None of us want to see you injured trying to fix your system. Don't attempt to repair the A/C unit yourself. What you don't know can hurt you. The dangers are very real.
