Why is There Ice on My Air Conditioner?


Your air conditioner should keep your house at a cool temperature during the hot summer months, but sometimes the inside of the unit itself freezes up and this can affect its ability to function properly. Notify your HVAC technician immediately if you notice any buildup of ice so the problem can be addressed

Airflow Issues

Ice can form on the cooling or evaporator coil. Poor or restricted air flow could cause your AC unit to freeze. Reduced air flow as a result of a dirty air filter can cause the coils to become blocked by ice.

R-22 Leaks

When R-22 (or refrigerant) leaks from your AC unit it can result in ice buildup around the copper tubing. A trained HVAC professional with certification for handling refrigerant can find the refrigerant leak, repair it, and restore your system to good working order.

Handling a Frozen AC

If your AC unit freezes, turn off the air conditioner so that the problem does not get worse. Buildup of moisture on the AC unit can cause damage to the circuit board or even more seriously, a fire or complete system damage if you continue to operate it. Even after the ice melts it is best to contact a professional to determine the cause as it is likely to happen again.

Schedule Regular Maintenance

Routine maintenance is very important in detecting and averting potential problems. Remember to schedule preventive maintenance at least once per year. Your technician will thoroughly check your system to ensure that all parts are in good working order. Regular maintenance can save you a lot of money in long run.
