Why Your AC Making Ice is Actually a Bad Thing

A Common but Dangerous Misconception

One of the most persistent myths we encounter at Just Better Air Conditioning and Heating LLC is that ice formation on your air conditioner’s coils is a sign that it’s working extra hard to keep you cool. This couldn’t be further from the truth!

When you see ice building up on your AC unit, it’s actually a warning sign that something’s wrong. Let’s break down why this happens and what it means:

Why Ice Forms:

  • Restricted airflow from dirty filters
  • Low refrigerant levels due to leaks
  • Malfunctioning blower motors
  • Blocked or dirty evaporator coils

The Real Impact:

Ice formation can lead to:

  • Reduced cooling efficiency
  • Higher energy bills
  • Potential compressor damage
  • Complete system failure if left untreated

If you notice ice on your AC unit in Chandler, Tempe, or the Ahwatukee Foothills Village area, don’t wait for it to “solve itself.” This issue requires professional attention to prevent costly repairs down the line.

Remember: A properly functioning air conditioning system should never form ice, even when running at maximum capacity. If you spot ice, turn off your system and contact a certified HVAC professional immediately.

Don’t let myths about AC performance cost you money and comfort. Trust the experts who understand the science behind your home’s cooling system.
