Why Choose Us

How Heating Specialties Inc handles furnace not heating repair

Our technicians follow a systematic approach to diagnose and repair furnaces that are not heating properly. The process begins with a thorough inspection of your furnace and thermostat settings to rule out simple causes like incorrect thermostat configuration or a dirty filter. We then examine the ignition system, gas supply, heat exchanger, and airflow components to identify why heat production has stopped.

For furnace igniter replacement, our technicians test the hot surface igniter or standing pilot assembly depending on your system type. A faulty igniter prevents the furnace from lighting the burners, which directly causes cold air to flow through your vents. We also check flame sensors and gas valves to ensure proper operation throughout the heating sequence.

If your furnace is not turning on at all, our furnace not turning on repair service covers electrical issues, limit switches, and control board failures. For gas furnaces, we verify the gas valve is receiving power and delivering fuel safely to the burners. Heat exchangers are inspected for cracks that could allow carbon monoxide to enter your home, which is a critical safety concern we take seriously on every service call.

After identifying the faulty component, we provide a clear estimate before proceeding with repairs. We use quality replacement parts matched to your furnace brand and model, then verify the system operates correctly through a complete heating cycle. Our goal is to leave your furnace running safely and efficiently, producing consistent warmth throughout your South Jersey home.

FAQ

Frequently Asked Questions About Furnace not heating repair

How long does it take to repair a furnace that is not heating?

Most furnace not heating repairs take between one and three hours depending on the root cause. Ignition problems like a faulty igniter or flame sensor can often be resolved in under an hour. More complex issues involving gas valves or heat exchangers may require additional time for safe diagnosis and proper installation. Our technicians provide a time estimate after diagnosing the problem during the initial inspection.
Several issues cause a furnace to cycle without heating your home. The most common causes include a faulty igniter that fails to light the burners, a dirty or malfunctioning flame sensor that shuts off gas flow prematurely, a clogged air filter restricting airflow and triggering safety shutoffs, a malfunctioning thermostat failing to signal heat demand correctly, and problems with the gas supply valve. Our technicians test each component systematically to identify the specific cause affecting your system.
If your furnace is less than 15 years old and the repair cost is less than half the value of a new system, repair is typically the better choice. Consider replacement if your furnace requires frequent repairs, has efficiency ratings below 80% AFUE, or shows signs of heat exchanger damage. Our technicians help you weigh repair costs against long-term operating expenses so you can make the best decision for your home budget.
Preventive maintenance keeps your furnace running efficiently through South Jersey winters. Replace or clean furnace filters every one to three months during the heating season. Schedule professional inspection and cleaning before each winter to catch worn igniters, dirty flame sensors, and other problems before they cause heating failures. Keep vents and returns unobstructed by furniture or drapes, and test your thermostat batteries regularly.
A furnace that completely stops producing heat during South Jersey’s coldest months qualifies as an emergency, especially for households with young children, elderly residents, or anyone with medical conditions sensitive to cold. Our emergency furnace repair service is available outside regular business hours for these urgent situations. We prioritize heating emergencies to restore warmth as quickly as possible.
A flickering or yellow gas flame often indicates incomplete combustion caused by a dirty or faulty flame sensor, misaligned gas jets, or restricted airflow. When the flame sensor cannot detect a stable flame pattern, it shuts off the gas valve as a safety precaution, leaving your furnace blowing cold air. Our technicians clean or replace flame sensors, check gas pressure, and verify proper airflow to restore safe, consistent heating operation.
