Why Won’t My Furnace Stop Running?

Posted On January 30, 2024 Furnace

Is your furnace blowing air without pause? If so, you’re probably feeling a bit concerned. First, your Old Bridge house most likely feels like an oven. On top of that, your utility bill will be considerably higher with your furnace constantly running. Believe it or not, this is a fairly common problem our professionals at Delco Heating & Cooling see frequently, so you don’t need to worry.

Before calling in a professional, check these three things:

  • Be sure you have the right thermostat settings.

Be sure your thermostat is set to a reasonable temperature. ENERGY STAR® recommends keeping it 8 degrees Fahrenheit cooler when you are sleeping during the winter to save on utility costs. If you set your thermostat to ultra-high temperatures, this may cause it to run constantly. Additionally, be sure to set your thermostat to Auto instead of On. The On setting causes it to run constantly, instead of incrementally.

  • Check the filter.

If you haven’t changed your furnace filter in a while, this could be the source of the problem. Over time, dust and debris clog your filter. This constricts airflow, which means the furnace has to work extra hard to maintain the desired temperature in your New Jersey home. Depending on how clogged the filter is, it may have your unit running nonstop.

  • Check the pilot light.

If the pilot light underneath the furnace is out, it can’t generate heat. In many cases, this causes your furnace to run continuously because it can’t reach the desired temperature. If the pilot light goes out again, call one of our knowledgeable and highly trained experts.

If none of the previous steps worked, schedule a repair with us at Delco Heating & Cooling. Here are three potential problems requiring our professional help:

  • Leaky ducts

If any of your ducts are punctured or blocked, this means heat isn’t being circulated properly. You’re losing heat and losing money through your utilities at the end of the month. One of our professionals can run a thermal analysis to determine the location of the leaks and repair your ductwork.

  • Broken fan motor

When your fan motor is obstructed, broken, or otherwise faulty, it can’t operate at full capacity. That means it has to run continuously to reach the set temperature. Unusual noises from your furnace are a sign that you have a broken motor.

  • Thermostat malfunction

Your thermostat is the brain of the operation. When it sends the wrong information to your furnace, a number of things can go bad. You could have a broken relay switch, or your thermostat could be producing an inaccurate temperature reading.

“I called Delco for a furnace repair and was very impressed with their prompt and reliable service.”

The technician was knowledgeable, efficient, and friendly, and took the time to clearly explain the issue and pricing. The repair was completed quickly, and my home is comfortable again. I also truly appreciate that Delco Heating & Cooling cares for and supports veterans. I will definitely call them again for any future HVAC needs.

“Delco Heating & Cooling are the best hvac and plumbers in New Jersey”

My hot water tank cracked last night and flooded my basement I called Delco Heating & Cooling because they fixed my air conditioning over the summer. The technician got here at 5pm and explained to me how although the crack is an area of in-repair he can schedule replacement Monday or check to see if they had my style hot water heater in their inventory and offered to replace it on the spot the same day and I was shocked that they would offer that level of service and I accepted and he had the replacement done by 10pm and was cleaned up and had the old hot water tank out of my home by 10:30 and me and my wife would recommend them to anyone literally
