Long-term issues that could arise if you don't repair your leaky AC unit include:
- A costly AC system repair bill
- Higher energy bills and increased energy use
- Exposure to substances that can harm your lungs and cause burns
- Damaging emissions that could harm the environment
With this guide you will be taken on a step by step procedure on how to safely and easily asses and repair any and all problems that your AC may have.
