HVAC Repair Madison WI | Call Commercial Air

Short cycling, where your furnace turns on and off too frequently, is common here and often caused by a dirty air filter, an oversized unit, or a faulty flame sensor. It wastes energy and strains the system. Our technicians perform a comprehensive diagnostic to pinpoint the exact cause—whether it's a simple filter change, a thermostat calibration for our fluctuating temperatures, or a component repair—to restore proper, efficient operation and protect your furnace.

In Madison, with our seasonal pollen, dust, and winter usage, we generally recommend checking your filter monthly and replacing standard 1-inch filters every 1-3 months. A clogged filter is a top cause of poor airflow, short cycling, and even system failures. During our maintenance visits, we check your specific filter type and home environment to provide a personalized schedule, ensuring your system breathes easily and runs efficiently all year.

Our local maintenance service is designed to prevent the issues Madison homes often see. We perform a detailed 20+ point check, including cleaning coils, checking refrigerant levels, testing safety controls, lubricating moving parts, and inspecting the heat exchanger for cracks. Crucially, we assess airflow and system cycling to catch problems like a dirty filter or improper calibration early. This proactive care improves reliability, efficiency, and can extend the life of your HVAC system.
