An AC that runs but isn’t cooling usually indicates restricted airflow, an incorrect refrigerant charge, or a thermostat/control problem. The most common cause is airflow blockage from a dirty filter or a clogged outdoor coil. Other culprits include low refrigerant from a leak, iced evaporator coils, blocked or damaged ductwork, or a failing blower or capacitor. A quick technician check is whether the outdoor fan runs but the large copper line never gets cool under load, which hints at a refrigerant issue. We diagnose and resolve these problems for homeowners around Schaumburg every day. For urgent cooling failures, Summers Plumbing Heating & Cooling offers same-day and 24/7 emergency AC repair with upfront pricing.

Before you schedule service, check:

• Thermostat set to Cool, 5°F below room temp; fan on Auto.
• Filter is clean and supply/return vents are open.
• Outdoor condenser is clear of debris and has free airflow.
• Any visible ice on lines or unusual water near the furnace.

Do not attempt to add refrigerant yourself; only licensed technicians should handle refrigerants. <br/> Updated: 2026-04-07 <br/> Need help in Schaumburg, IL? Call (331) 294-8710 or book online.
