Air Conditioning Repair Service Options in Chicago, IL
Compare Chicago air conditioning repair services for warm air, weak airflow, short cycling, freeze-ups, electrical faults, compressor problems, and refrigerant leaks. Use this directory to choose the right service, or start with AC diagnostics when the cause is unclear.
Warm air, ice on the refrigerant line, unusual condenser noise, and repeated cycling can have different causes. We check electrical components, airflow, coils, and refrigerant performance instead of assuming the system only needs a recharge.
Leak Detection
Electronic leak detection finds refrigerant leaks fast. We fix the leak first, then recharge the system—not the other way around.
Coil Cleaning
Dirty coils kill efficiency and compressors. We clean condenser and evaporator coils properly to restore full cooling capacity.
All Brands
We repair Carrier, Trane, Lennox, Rheem, Goodman, and all major AC brands. Our trucks stock common parts for same-day repairs.
Bernie's Heating & A/C has repaired Chicago ACs since 1992. We've diagnosed thousands of AC failures in Portage Park, Logan Square, Albany Park, Lincoln Square, and throughout the city. Your AC breaking on a 95°F day isn't unusual—it's the peak demand that stresses units until something fails.
Contact us for a written estimate based on your system and the work required.
AC Repair & Diagnostics
AC diagnostics start with electrical components such as capacitors, contactors, disconnects, and controls. We then check filters, coils, blower performance, static pressure, temperature split, and refrigerant readings to identify the actual cause of the cooling problem.
Repair timing depends on the diagnosis and parts availability. Common electrical components may be available the same day, while compressor and refrigerant-system work can require ordered parts and additional testing.
AC repair beats replacement when your system is under 12 years old and the repair costs less than half a new system. The same repair on a 16-year-old unit with other issues doesn't.

AC compressor repair usually means replacement—compressors rarely get repaired. If your AC is over 12 years old, replacement often makes more financial sense than compressor repair.
Compressors fail from running low on refrigerant (starvation), dirty condenser coils (overheating), or electrical issues. Most compressor failures are preventable with proper maintenance. Clean coils and correct refrigerant charge extend compressor life significantly.
Many compressors carry 5-10 year warranties. If yours fails under warranty, you pay labor only. We handle warranty claims with manufacturers directly. The paperwork takes time but saves you money.

AC maintenance prevents breakdowns during Chicago's hottest weeks. Our tune-ups clean both coils, check refrigerant levels, test capacitors and contactors, verify airflow, and measure amp draw. Takes about 90 minutes per system.
Spring AC maintenance catches problems before summer heat arrives. Capacitors showing high ESR readings fail when stressed by high temperatures. Contactors with pitting spark and fail. Dirty coils reduce capacity by 20-30% and stress compressors. All fixable during maintenance before they become emergency repairs.
We confirm the tune-up price when you book. Freon is not included. If the system is low on Freon, there is a leak that needs to be found before more refrigerant is added.
AC Tune-Up Service in ChicagoAC Refrigerant Leak Detection & Recharge
Refrigerant circulates in a closed system. If the charge is low, we locate the leak, explain the repair options, verify the repair, and then restore the specified refrigerant charge when appropriate.
Common leak points include condenser coils (road salt in Chicago corrodes them), evaporator coils (formaldehyde from building materials causes formic acid corrosion), and service port valves. Electronic leak detection pinpoints leaks fast. Nitrogen pressure testing verifies repairs hold.
Evaporator coil leaks cost more due to access—requires opening the air handler. Condenser coil leaks are usually cheaper to fix. Older R-22 systems with multiple leaks often aren't worth repairing.
Learn More About AC Refrigerant Leak RepairWhy Refrigerant Recharge Follows Leak Repair
Refrigerant recharge only makes sense after fixing the leak. AC systems are sealed—refrigerant doesn't evaporate or get used up. If your system is low, you have a leak. Recharging without fixing the leak means paying for refrigerant every season while the slow leak continues.
Refrigerant pricing varies with market conditions and the amount required. Your typical 3-ton system holds about 6-9 pounds.
Refrigerant recharge on older R-22 systems costs more because R-22 production stopped in 2020. R-22 prices fluctuate widely. If your R-22 system needs major refrigerant recharge, replacement often makes more financial sense than repeated recharges.
