Debunking a Common Air Conditioning Misconception
One of the most persistent myths we hear at United Air Conditioning is that an air conditioner 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 behind this issue can help prevent costly repairs.
When you see ice forming on your air conditioning system’s components, it’s actually a sign that something isn’t working correctly. Here’s what’s really happening:
Common causes of AC freezing include:
• Low refrigerant levels due to leaks
• Dirty air filters restricting airflow
• Malfunctioning blower motors
• Blocked return air ducts
• Mechanical failures
The science behind the freeze:
Your AC unit doesn’t create cold air – it removes heat from your home’s air. When components freeze, it’s because:
1. Reduced airflow prevents warm air from flowing over the evaporator coil
2. The coil becomes too cold
3. Moisture in the air freezes on the cold surface
The solution isn’t to “turn down” your system – it’s to address the underlying problem. Regular maintenance from qualified technicians can prevent these issues before they start.
Remember, a properly functioning air conditioning system should never freeze up, regardless of how low you set your thermostat. If you notice ice formation, it’s time to call a professional to diagnose and fix the real problem.
Don’t let myths about AC operation cost you money in repairs or reduced efficiency. Understanding how your system actually works is the first step in maintaining comfortable, reliable cooling for your home.
