If your AC blows warm air on and off, start with quick checks. Set the thermostat to Cool and a lower temperature. Replace the air filter. Make sure the outdoor breaker and disconnect are on, and clear debris from the condenser. If it still turns warm, it likely needs professional diagnostics for issues like low refrigerant, a bad capacitor, or thermostat faults. ABC offers same-day, 24/7 AC repair in Chicago and nearby, with NATE-certified techs and upfront pricing.
- Thermostat: Cool mode, fan Auto

AC compressor replacement pricing depends on your system and is confirmed after an on-site diagnosis. A technician will evaluate compressor condition, refrigerant type, system size, accessibility, and any warranty coverage. We service all brands and can install Carrier equipment when replacement is the best option. Same-day and 24/7 service are available in Chicago and nearby suburbs.
Quick checks:
- Verify if your compressor is still under parts warranty.
- If the system is older or has repeat failures, consider full AC replacement.
