This is an urgent issue in Wood Dale, as it can lead to compressor failure—a much costlier repair. Turn the system to 'off' and switch the fan to 'on' to help thaw the coil. Do not chip at the ice. Call us promptly. We'll identify the cause, such as a dirty filter or leak, perform the necessary repair, and ensure your system operates safely and effectively.

Regular maintenance is key. We recommend changing your air filter monthly during peak seasons and scheduling a professional tune-up twice a year—once for cooling and once for heating. This allows us to clean coils, check refrigerant levels, and ensure electrical components are tight, which are common culprits for freezing in our local climate. A well-maintained system runs more efficiently, prevents sudden breakdowns, and can extend the life of your equipment, saving you money and hassle.
