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 2008. 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.

Most AC repairs cost $180-$600 in Chicago. Capacitor replacement runs $180-220. Refrigerant leak repairs with recharge cost $300-600 depending on leak location. Compressor replacement hits $1,500-2,500, which is why we protect compressors by fixing refrigerant leaks and cleaning coils before they fail.

AC Repair

AC repair starts with systematic diagnostics. Check electrical components first—capacitors and contactors fail frequently and cause 40% of no-cooling calls. Then airflow—dirty filters and coils cause another 30% of problems. Finally refrigerant levels—actual leaks account for maybe 20% of issues.

Most Chicago AC repairs finish in 1-2 hours. We stock capacitors, contactors, and common electrical parts on our trucks. About 70% of repairs complete same-visit. Compressor replacements or major refrigerant leaks need parts ordering, which typically takes 1-3 days.

AC repair beats replacement when your system is under 12 years old and the repair costs less than half a new system. A $400 repair on an 8-year-old AC makes sense. The same repair on a 16-year-old unit with other issues doesn't.

AC Compressor Repair

AC compressor repair usually means replacement—compressors rarely get repaired. When your compressor fails, you're looking at $1,500-2,500 installed. 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 (typically $800-1,200). We handle warranty claims with manufacturers directly. The paperwork takes time but saves you money.

AC Maintenance

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.

AC maintenance costs $89-129 in Chicago. Skip it and you'll likely pay $200-400 for an emergency repair visit when your system fails mid-summer. Plus you're sweating while waiting for service during peak season when every HVAC company is booked days out.

AC Refrigerant Leak Repair

AC refrigerant leak repair means finding the leak, fixing it, then recharging the system. Refrigerant is a closed-loop system—it doesn't "get used up." Low refrigerant means you have a leak. Companies that recharge without finding the leak are running a scam that costs you money every season.

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.

AC refrigerant leak repair costs $300-600 in Chicago depending on leak location and severity. 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.

AC Tuneup

AC tuneup means cleaning coils, checking refrigerant charge, testing electrical components, verifying airflow, and measuring performance. The goal is catching problems before they cause failures during summer's peak heat.

Chicago's combination of heat, humidity, and cottonwood seeds in June stresses AC systems hard. Dirty condenser coils from cottonwood fluff cause high head pressure. High head pressure overworks compressors. Compressors fail during heat waves when they can't shed the extra load.

AC tuneup is preventive—fixing small issues before they become expensive repairs. A $15 capacitor showing early failure signs during spring tuneup gets replaced before it fails in July and leaves you without AC for days while every HVAC company is slammed with emergency calls.

Refrigerant Recharge

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.

Chicago AC technicians charge $75-150 per pound of R-410A refrigerant. Your typical 3-ton system holds about 6-9 pounds. A full recharge runs $450-1,350 just for refrigerant. Add the leak repair and you're at $600-2,000 total depending on leak severity.

Refrigerant recharge on older R-22 systems costs more because R-22 production stopped in 2020. R-22 prices fluctuate wildly—sometimes $150+ per pound. If your R-22 system needs major refrigerant recharge, replacement often makes more financial sense than repeated recharges.
