Cold air from your furnace often indicates a pilot light or ignition issue, a dirty air filter restricting airflow, or a malfunctioning thermostat. First, check your thermostat settings and replace the filter. If the problem persists, it’s time to call an emergency furnace repair service to avoid prolonged discomfort during Sussex County’s harsh winters.

When should I replace my furnace instead of repairing it?

If your furnace is over 15 years old, requires frequent repairs, or has a cracked heat exchanger, replacement is usually more cost-effective. Newer models are significantly more energy-efficient, which can lower your monthly heating bills. A qualified HVAC contractor in Newton NJ can help you weigh the pros and cons based on your specific situation.
