Airtek Systems: Local HVAC Services Serving Caledonia 53108.0

Yes, ice buildup is a serious sign that your system needs attention. It's often caused by low refrigerant, a dirty air filter, or a failing blower motor—all of which force your system to work harder and can lead to a complete breakdown. Don't try to chip the ice off yourself. Call Airtek Systems. Our technicians will safely diagnose the root cause, perform the necessary repair, and get your AC running efficiently to handle our Wisconsin summers.

Faulty thermostats are a common issue here, often due to aging wiring, dust buildup inside the unit, or a need for recalibration. A malfunctioning thermostat can make your HVAC system cycle on and off incorrectly, wasting energy and causing uneven temperatures. Our experts at Airtek Systems can test your thermostat, clean the components, and determine if a repair or an upgrade to a more reliable programmable or smart model is the best solution for your home.

The single most important task is changing your air filter and having a professional tune-up. A clean filter ensures proper airflow, which is critical to preventing the ice buildup we often see on coils. Our comprehensive summer tune-up includes checking refrigerant levels, cleaning the condenser coils, inspecting electrical connections, and testing the system's overall operation. This proactive maintenance helps prevent mid-summer breakdowns, improves efficiency, and extends the life of your AC unit.
