We live in the “Do It Yourself” age. The internet has made it easier than ever for a homeowner to find advice for ways to tackle numerous jobs around the house without needing to call for professional repairs. YouTube alone has thousands of videos explaining DIY tactics for almost any job imaginable.
There are limits, however, to what an enthusiastic amateur can achieve. One of those limits is repairing broken refrigeration systems, such as air conditioners. So the answer to “Can I repair my AC myself?” is “no.” Repairing a busted air conditioner must be left to licensed HVAC professionals.
