DCS Mechanical | Licensed HVAC Repair in Aurora, IL

Short cycling is a common furnace issue in Aurora, often caused by an overheating system, a dirty air filter restricting airflow, or a malfunctioning flame sensor. This rapid cycling puts extra wear on your furnace and increases your energy bills. Our technicians will perform a thorough inspection to pinpoint the exact cause—whether it's a simple cleaning, a component repair, or addressing sizing issues—and get your system running smoothly and efficiently again.

Aurora's seasonal shifts contribute to algae and mold growth in the damp, dark environment of your condensate drain line. The best prevention is a professional HVAC tune-up, where we will flush and clean the drain line as part of our routine maintenance. We can also install a preventative safety switch (like a float switch) that will shut your system off if a clog occurs, preventing costly water damage to your furnace or home.

Our comprehensive Aurora furnace tune-up is specifically designed to catch and prevent local issues. It includes cleaning the flame sensor and burners to prevent short cycling, inspecting and testing safety controls, flushing and treating the condensate drain line to prevent clogs, checking for proper airflow, and ensuring all components are operating safely and efficiently. This proactive service is your best defense against unexpected breakdowns.
