Furnaces are essential for household heating systems in New Cumberland, PA, but various issues can disrupt their operation. Understanding these five common problems will allow you to recognize and address potential malfunctions promptly.

1. Dirty Air Filters

When filters are clogged with dust, dirt, or debris, they obstruct proper air circulation, forcing the furnace to work harder to maintain the desired temperature. If not addressed promptly, this increased strain can lead to overheating, decreased efficiency, and even system failure. Regularly replacing or cleaning air filters every one to three months is crucial to prevent this issue.

2. Malfunctioning Thermostat

A malfunctioning thermostat can lead to erratic temperature control or failure to activate the furnace when needed. Issues may arise from wiring problems, dead batteries, or sensor inaccuracies. Battery replacement could resolve the problem, but you might need professional help for more complex issues.

3. Pilot Light or Ignition Issues

For gas furnaces, pilot light or ignition system issues can disrupt heating. A malfunctioning pilot light may result from clogs, thermocouple problems, or faulty gas valves, causing the furnace to blow cold air or fail to ignite. Ignition problems, whether due to faulty electronic ignition or pilot control issues, require inspection and repair by a professional technician to ensure safe and efficient furnace operation.

4. Wear and Tear

Continuous usage causes wear and tear on furnace components over time. Components such as bearings, belts, and motors may wear out or become loose, leading to unusual noises, reduced heating efficiency, or a complete breakdown. Regular maintenance and timely replacement of worn parts are crucial to prevent extensive damage and maintain the furnace’s lifespan.

5. Lack of Maintenance

Neglecting regular maintenance, including inspections, cleaning, and tune-ups, can lead to many problems. Routine maintenance helps to identify potential issues early, keep the system running efficiently, and prolong its lifespan. Professional HVAC servicing can address minor concerns before they escalate into more significant problems.
