HVAC Repair Bensalem PA | Call National Refrigeration and Air Conditnng Prdct

In our Bensalem winters, a common culprit for ignition failure is a dirty or faulty flame sensor. Over time, it can become coated and fail to detect a flame, causing the system to shut down as a safety measure. Our technicians can quickly clean or replace the sensor to restore reliable ignition and heat for your home.

This is called short cycling, and in Bensalem homes, it's often due to an oversized system, a clogged air filter restricting airflow, or a malfunctioning thermostat. It puts extra strain on your unit and wastes energy. We'll diagnose the root cause—whether it's a simple filter change or a more complex system evaluation—to restore normal, efficient operation.

Before our cold snaps hit, the most critical step is to schedule a professional furnace tune-up. This includes cleaning key components like the flame sensor and heat exchanger, checking for gas leaks, and testing safety controls. This proactive service can prevent ignition failures and ensure your system runs efficiently all season long.
