Ice buildup on outdoor units in Grantsburg is often caused by restricted airflow, low refrigerant levels, or dirty coils. Our technicians will diagnose the root cause—whether it's a clogged filter, refrigerant leak, or mechanical issue—and perform necessary repairs like coil cleaning, refrigerant recharge, or component replacement to restore proper operation and prevent future freezing.

Signs of a clogged condensate drain include water leaks near your indoor unit, musty odors, or the system shutting off unexpectedly. We use specialized tools like wet/dry vacuums and drain snakes to clear blockages safely, then apply preventive treatments to inhibit mold and algae growth—common in Grantsburg's humid seasons—to help avoid recurring clogs.
