Furnace Repair FAQs in Syracuse, NY

Common furnace repair questions answered by NearbyHunt Pros

Use the filter size specified on your current filter frame or in your furnace manual. Common sizes include 16x20x1, 16x25x1, 20x20x1, and 20x25x1 inches. The last number indicates thickness. Thicker filters (4-5 inches) require compatible filter cabinets but need less frequent replacement. Using the wrong size allows air to bypass the filter, reducing effectiveness. Never force an incorrect size into the filter slot.

A gas furnace contains several key components including the burner, heat exchanger, blower motor, thermostat, gas valve, ignition system, and flue pipe. The burner mixes gas with air for combustion, while the heat exchanger transfers heat to the circulating air without mixing combustion gases. The blower motor pushes heated air through your ductwork, and the thermostat controls when the system cycles on and off.

A flame sensor is a metal rod positioned in the burner flame that detects whether combustion is occurring. It sends a small electrical current through the flame to the control board, confirming ignition. If the sensor fails to detect flame within a few seconds of gas valve opening, it shuts down the furnace for safety. Dirty or corroded flame sensors are a common cause of furnace failures and are easy to clean or replace.

Limit switch replacement costs $150-$300 including parts and labor. The switch costs $20-$75, with labor running $100-$200. Before replacing the limit switch, technicians should address why it's tripping, as the switch itself may be functioning correctly but responding to overheating from dirty filters or airflow problems. Simply replacing a tripping switch without fixing the cause leads to repeat failures.

The burner orifice is a small opening that meters gas flow into the burner, controlling the fuel-air mixture for proper combustion. Orifice size is specific to the gas type (natural gas vs. propane) and altitude. Using wrong-sized orifices causes improper combustion, yellow flames, and carbon monoxide production. Orifice changes are part of fuel type conversions and altitude adjustments.
