Frozen AC Coil Repair in Chicago, IL

Frozen AC coil repair in Chicago, IL begins with turning the cooling off. If you see ice on the copper line outside or frost on the indoor coil, running the AC longer only builds more ice and can send liquid refrigerant back to the compressor. Set the thermostat to OFF and the fan to ON to start the thaw.

A coil freezes when it gets too cold, and that happens for two main reasons. Low airflow is the first: a clogged filter, closed supply registers, a dirty evaporator coil or a weak blower motor lets the coil temperature drop below 32 degrees. Low refrigerant charge is the second, because a system that is short on refrigerant runs lower suction pressure and a colder coil.

Our crew checks both. We measure static pressure across the air handler, inspect the evaporator face for matted dust and pet hair, and put gauges on the system to read suction pressure and superheat. When the coil is dirty, we clean it with a non acid coil cleaner. When the charge is low, we go hunting for the (/services/refrigerant-leak-repair).

Melting ice also floods the drain pan, so we check the drain line too. Call (866) 703-1217.

Central AC Repair FAQs

Common questions about central AC repair

Questions we hear about Frozen AC Coil Repair in Chicago, IL.

Talk to our crew
Is it worth repairing an older R-22 system?
Sometimes. R-22 has not been produced or imported in the US since 2020, so any recharge uses reclaimed refrigerant at a high price. A small electrical repair on an R-22 unit can still make sense. A major leak or a failed compressor on one usually does not. We'll give you both numbers.
Why is there ice on my AC lines?
Ice forms when the indoor coil gets too cold, usually from low airflow (dirty filter, dirty coil, weak blower) or low refrigerant charge. Turn cooling off and run the fan to thaw it, then call us. Running a frozen system can damage the compressor.
Can you just add refrigerant to my AC?
We can, but it rarely makes sense on its own. A central AC system is sealed, so low refrigerant means a leak. Topping it off without fixing the leak means the charge leaks out again. We find the leak, repair it and weigh in the correct charge.
How long does a central AC system usually last?
Many central air systems run 12 to 15 years with regular maintenance. Units near the coast, where salt air corrodes coils, and units in very long cooling seasons often wear out sooner. Age alone is not a reason to replace, but it factors into repair decisions.
Why is water leaking from my indoor unit?
Most of the time it is a clogged condensate drain line, a cracked or rusted drain pan, or a frozen coil that is melting. Turn the system off to limit water damage and call us. We clear the line, check the pan and test the safety float switch.
