Ice on the copper lines means the coil is running too cold. The cause is almost always airflow or refrigerant charge.

Do this first

Turn the system to Off and the fan to On. Let the ice melt for two to three hours before you run cooling again.

Do not chip the ice

Scraping ice can puncture the coil or the lines. Check the filter, make sure supply vents are open, and call us if it freezes again.
