Common AC Problems We Fix in Lombard IL

Air conditioning systems in Lombard IL face specific stressors—from summer humidity to seasonal dormancy. Here are the most frequent issues we encounter and repair:

Refrigerant Leaks

Low refrigerant causes weak cooling and constant running without proper comfort. We locate leaks, repair them properly, and recharge the system to manufacturer specifications.

Frozen Evaporator Coils

Restricted airflow or low refrigerant can cause coils to freeze. We thaw the system, identify the root cause, and adjust airflow or refrigerant levels to prevent future freezing.

Compressor Failures

The compressor is the heart of your AC; when it fails, cooling stops. We diagnose the problem accurately and recommend repair or replacement based on the system’s age and condition.

Electrical Issues

Capacitors, contactors, and wiring issues are common in older homes. We safely repair components and ensure your system meets current safety standards.

Thermostat Malfunctions

Sometimes the problem isn’t the AC unit but the control system. We troubleshoot and replace faulty thermostats, including smart‑thermostat integration.

Clogged Condensate Drains

Lombard’s humidity means your AC removes a lot of moisture. Clogged drains can cause water damage or shutdowns. We clear blockages and install safety switches to prevent overflow.
