Plumbing Expert Joe Prestia Explains Why a Heating System May Stop Working During Cold Weather in HelloNation

The article outlines how boiler, furnace, and thermostat issues can disrupt hot water and heat circulation in the home.

YORKTOWN, N.Y., Aug. 24, 2026 /PRNewswire/ -- Why is the heating system not working when the house feels freezing? HelloNation has published the answer in an article featuring insights from Joe Prestia of Pipe Wizard in Yorktown, New York.

The HelloNation article explains that when a heating system fails, the cause is not always obvious. While many homeowners assume the thermostat is the problem, issues with a boiler, furnace, or circulating pipes may be preventing heat from reaching the home. Identifying the source early helps restore comfort and prevent more costly repairs.

The first step highlighted in the article is checking the thermostat. Ensuring it is set to heat, adjusted to the correct temperature, and receiving power can sometimes resolve the issue quickly. Homeowners are also encouraged to confirm that the heating system has not lost power at the breaker or emergency switch.

For homes with a boiler, low water pressure or trapped air can interrupt circulation. A boiler depends on proper pressure to move hot water through radiators or baseboard piping. Air pockets in pipes may block flow, causing uneven heating or cold rooms. Monitoring pressure levels and bleeding radiators are practical maintenance steps that support reliable performance.

Furnace-related issues are also discussed in the article. Dirty filters, faulty ignition components, or malfunctioning burners can prevent warm air from circulating effectively. Clogged filters restrict airflow, strain the furnace, and reduce efficiency. Routine maintenance and filter replacement help maintain steady heat and extend system life.

The article also notes that frozen pipes and blocked vents can reduce heating efficiency. In colder climates, water inside pipes may freeze, preventing proper circulation. Furniture or debris blocking vents can restrict airflow, making rooms feel colder than they should. Checking vents and ensuring clear airflow supports overall heating system performance.

Unusual noises such as banging, clanking, or whistling may signal deeper problems. These sounds can indicate mechanical failure, trapped air, or circulation pump issues within the boiler or furnace system. Ignoring these warning signs may lead to more serious breakdowns.

Professional inspection is presented as the most reliable way to diagnose heating system concerns. Technicians evaluate boilers, furnaces, thermostats, and pipes while measuring pressure and airflow. Early diagnosis prevents minor problems from escalating into emergency situations during extreme cold.

Preventive maintenance is emphasized throughout the HelloNation article. Replacing filters regularly, monitoring boiler pressure, checking the thermostat, and scheduling annual inspections all help maintain a dependable supply of hot water and warm air. Consistent maintenance improves efficiency and reduces the risk of unexpected failure.

The article concludes that heating issues can stem from multiple causes, including thermostat settings, low boiler pressure, clogged furnace components, frozen pipes, or circulation problems. By recognizing early warning signs and scheduling timely maintenance, homeowners can keep their heating system operating safely and efficiently throughout the coldest months.
