Seeing ice on your air conditioner might seem harmless—especially on a hot summer day—but it’s actually a red flag that your system isn’t working as it should. At SRV Heating and Air, we’ve helped countless Lehi homeowners and business owners get to the bottom of frozen AC issues, and we know how quickly a minor issue can turn into a major repair if left unchecked.

What Causes Ice to Form on Your AC?

Several issues can cause your air conditioner to freeze up. The most common reasons include:

  • Restricted Airflow: A clogged air filter, blocked vents, or dirty coils can limit the amount of air moving through your system. Without enough airflow, the evaporator coil can become too cold and cause moisture to freeze.

  • Low Refrigerant: If your system is low on refrigerant due to a leak or poor charge, the evaporator coil temperature drops below freezing, leading to ice buildup.

  • Faulty Blower Fan: If the blower fan isn’t working properly, it can’t move enough air across the coils to maintain the correct temperature balance.

  • Thermostat or Control Issues: If your thermostat isn't reading indoor temperatures accurately, it can keep the system running too long—causing it to overcool and freeze up.

Why You Should Never Ignore It

Ignoring ice on your AC can result in serious consequences:

  • System Damage: Ice can strain components like the compressor, which is expensive to replace.

  • Reduced Efficiency: A frozen system won’t cool your home properly, leading to discomfort and higher energy bills.

  • Complete Breakdown: Left unresolved, freezing issues can cause your system to shut down completely—especially during peak summer heat when you need it most.

What to Do if You See Ice on Your Unit

If you notice ice on your AC unit, the first thing to do is turn it off. This prevents further damage and allows the system to defrost. Then, check your air filter—if it’s dirty, replace it. However, this alone may not fix the issue. You’ll want a professional to inspect your system to determine the root cause.
