Licensed HVAC Services in Chicago, IL 60628 - Ingram Heating & Cooling

A frozen AC unit is often caused by restricted airflow from a dirty filter, low refrigerant levels from a leak, or a failing blower motor. These issues are common in our humid climate. Our technicians first safely thaw the system, then pinpoint the root cause—like locating and sealing refrigerant leaks—to prevent a costly repeat freeze-up.

Signs of a refrigerant leak include your AC blowing warm air, ice forming on the refrigerant lines or coils, a noticeable hissing sound, and a sudden spike in your energy bills. If you notice any of these, call us. We use specialized electronic leak detectors to find even small leaks and perform EPA-compliant repairs to restore cooling power and efficiency.

Short-cycling, where your furnace turns on and off frequently, is often due to a dirty flame sensor, restricted airflow, or an overheating issue. This not only wastes energy but can lead to premature system failure. Our experts will clean critical components, check for blockages in your vents and filter, and ensure proper operation to keep your home consistently warm.
