A few years ago, I lived in an apartment that had an old, creaky air conditioner that broke down a lot. I hated it, but I got really good at learning various signs of air conditioner trouble. I know how to recognize smells and sounds that mean trouble, and I know what different strange sounds that come from the air conditioner mean. I now live in a much nicer apartment, but when my air conditioner started giving me trouble last week, I knew just what to do. I've decided that I want to share my experiences with others. Once you learn a few DIY troubleshooting techniques and some preventative maintenance, it's easy to keep your air conditioner running. I can also help you learn what signs require help from an experienced HVAC technician. Check out my blog posts for answers to your AC questions.
