Bernal Heating & Air Conditioning - Aurora's Experienced HVAC Repair

Short cycling is a common issue in Aurora, often caused by an oversized furnace, a dirty air filter, or a faulty thermostat or flame sensor. It wastes energy and wears out your system. Our technicians will perform a comprehensive diagnosis to pinpoint the exact cause—whether it's a simple filter change, a sensor cleaning, or a more complex sizing assessment—and provide a reliable repair to restore proper, efficient operation for your home.

Furnace ignition failures in Aurora can stem from a faulty ignitor, a dirty flame sensor, a gas valve issue, or problems with the pilot light or electronic controls. While not always an immediate safety hazard if the gas is off, a non-igniting furnace leaves your home without heat, which is a serious concern in our climate. We treat these as priority service calls. Our experts will safely troubleshoot the ignition system, perform the necessary repairs, and ensure your furnace lights reliably and operates safely.

Proactive maintenance is key to avoiding common Aurora furnace issues. We recommend an annual professional tune-up before each heating season. Our service includes cleaning the flame sensor and burners, checking the ignition system, testing safety controls, and ensuring proper airflow—all critical steps to prevent short cycling and ignition failures. This neighborly upkeep not only improves reliability and safety but also enhances efficiency, saving you money on winter energy bills.
