Wilmers Heating & Cooling Service | Local HVAC Repair in Hancock, MI

Yes, reduced cooling is a common sign of a refrigerant leak, especially given our local temperature swings that stress AC systems. Our technicians first perform a thorough inspection using electronic leak detectors to pinpoint the exact location. We then repair the leak, evacuate the system to remove any moisture or contaminants, and recharge it with the precise amount of refrigerant specified by the manufacturer. This restores optimal efficiency and cooling power, preventing further damage and higher energy bills.

Short cycling—where your system turns on and off too frequently—is often caused by a malfunctioning thermostat, a common issue in our area due to dust and humidity. The problem could be incorrect calibration, faulty wiring, or a failing sensor. We'll test the thermostat's accuracy, check the wiring connections, and ensure it's properly located away from heat sources or drafts. Often, upgrading to a modern, programmable thermostat not only solves the short cycling but also improves your home's comfort and energy efficiency significantly.

Our preventative maintenance visits are designed specifically to catch issues like small refrigerant leaks or early thermostat failures before they cause a breakdown. We perform a comprehensive check, including inspecting refrigerant lines for leaks, testing thermostat calibration and operation, cleaning coils, checking electrical connections, and ensuring all components are functioning correctly. This proactive service helps extend the life of your system, maintains its efficiency, and gives you peace of mind through Hancock's cold winters and warm summers.
