Why Your AC Unit Is Not Actually Freezing Up From Being Too Cold

A Common Air Conditioning Misconception

One of the most frequent myths we encounter at Joplin’s Air Conditioning & Heating is that an AC unit freezes up because it’s working “too hard” or making the air “too cold.” This couldn’t be further from the truth, and understanding the real reason can help you maintain your system more effectively.

The Real Reason Behind AC Freeze-Ups

When your air conditioner develops ice, it’s actually a sign that something’s wrong, not that it’s working overtime. Here are the typical causes:

• Restricted airflow (often due to dirty filters)
• Low refrigerant levels
• Mechanical problems
• Dirty evaporator coils

What You Need to Know

Your air conditioning system is designed to operate within specific temperature ranges, and freezing up is never part of normal operation. When your system is running correctly, it should:

• Maintain consistent airflow
• Operate at proper pressure levels
• Cool your home efficiently
• Run without ice formation

Preventing Freeze-Ups

Regular maintenance is your best defense against AC freeze-ups. Here are some preventive steps:

1. Change air filters monthly
2. Keep outdoor units clear of debris
3. Schedule professional maintenance twice yearly
4. Monitor system performance

Don’t wait until your system freezes up to take action. Regular maintenance from qualified professionals can prevent most cooling system problems and extend your unit’s lifespan.

Remember, if you notice ice forming on your AC unit, turn it off immediately and contact a professional HVAC technician for proper diagnosis and repair.
