All Systems Heating & Air Conditioning - Sheboygan's Certified HVAC Services

Ice buildup on your outdoor unit is often a sign of restricted airflow, low refrigerant, or a failing component. While it's a common issue in our climate, it should be addressed promptly. Running the system with ice can cause serious damage to the compressor. We recommend turning the system off at the thermostat and calling us for a diagnosis to prevent a minor repair from becoming a major, costly replacement.

Absolutely. Thermostat malfunctions are a frequent call we get, often due to wiring issues, dead batteries, or age. Our technicians will test your thermostat and wiring to determine if it needs recalibration, repair, or replacement with a modern, more efficient model. A properly functioning thermostat is key to maintaining consistent comfort and managing your energy bills, especially during our chilly winters and humid summers.

The best defense is proactive maintenance. We recommend a professional tune-up for your heating system in the fall and your cooling system in the spring. This service includes cleaning components, checking refrigerant levels, testing safety controls, and ensuring all parts are in good working order. This regular care can prevent many of the issues we see locally, improve efficiency, and extend the life of your equipment.
