Ice on your AC might seem harmless, but it signals an underlying problem that will only get worse if ignored. Here are the most common causes and what to do about them.
Low Refrigerant
Refrigerant absorbs heat from inside your home. When levels are low due to a leak, the coil cannot absorb enough heat and ice begins to form.
Dirty Coil or Air Filter
A clogged filter blocks airflow over the evaporator coil, preventing it from pulling heat out of the air. When that process slows down enough, ice builds up. Keeping your filter clean is one of the easiest ways to prevent this.
Poor Airflow
Beyond a dirty filter, airflow problems can stem from blocked vents, damaged ductwork, an improperly sized filter, or a failing blower motor or fan. Any of these can cause refrigerant to over-cool the air around the coil and lead to ice formation.
What To Do
Do not attempt a DIY fix. Ice on your AC can have several causes that overlap, and a professional can accurately diagnose and address the root issue. Attempting to thaw or remove the ice yourself can cause further damage without solving the problem.
