Common Heating Hazards and How To Spot Them
Winter is here, and Colorado homeowners are now relying on their heating systems every day to keep their homes warm and cozy while the snow falls and the icy wind howls outside. And with all that usage, this is the prime time for heating problems to rear their ugly heads.
Some heating issues can increase the heating bills, leave the house feeling chilly, or even take the heater out of commission for a day or two. But as scary as those scenarios are, other heating problems can be even scarier – and more dangerous. This article will explain the biggest dangers of a faulty heater and how homeowners can identify them.
Carbon Monoxide Leaks
Perhaps the most terrifying of all heater problems is a carbon monoxide leak. In gas or oil-burning furnaces, any carbon monoxide produced by the fuel combustion is vented through the flue or exhaust vent. But if the flue or exhaust pipe leaks (due to corrosion, damage, etc.), it can cause carbon monoxide to enter the home. CO leaks can also occur due to a faulty pilot light or cracked heat exchanger.
Carbon monoxide poisoning is a very serious health risk, as it can cause unconsciousness, damage to internal organs, and even death. To protect against a carbon monoxide leak, homeowners should install CO detectors throughout the home (particularly near the furnace or other gas appliances) and have their heater serviced by a professional every year. If they notice any symptoms of CO poisoning, such as headaches, nausea, dizziness, shortness of breath, chest pain, fatigue, or confusion, they should exit the home and call their local emergency services at once.
Mold Growth Inside the Heater or Air Ducts
Another dangerous issue to watch out for is mold development inside the home’s air ducts or the heater. Mold growth is most common in heat pump systems, which function as heaters and air conditioners. In cooling mode, the unit helps remove moisture from the home’s air, condensing it from vapor into liquid. If this liquid doesn’t drain away immediately, it can facilitate mold growth very quickly, and that mold can survive inside the unit all year round. The mold spores can then spread to the home’s air ducts and throughout the home as air flows through the system.
Mold in the heating system or ductwork can have negative health outcomes. It can cause respiratory irritation or infections, exacerbate allergies and asthma symptoms, and significantly reduce indoor air quality. If homeowners develop any of these symptoms, notice a musty smell, or can see mold growth in their air ducts or in and around their heater, they should call a professional for a heater cleaning or air duct cleaning as soon as possible.
Overheating
Lastly, overheating a heater or furnace can be extremely dangerous and surprisingly common. Overheating can occur for various reasons, such as restricted airflow (usually due to a dirty furnace filter), short cycling (the unit frequently turns on and off), faulty internal components, or old age.
Overheating can cause the heat exchanger to crack (as mentioned above, lead to a carbon monoxide leak), damage the blower motor or other key components, and even cause a furnace fire. Some signs of an overheating furnace include burning smells, a loud humming noise from the heater, or shutting down before the thermostat reaches the correct temperature.
If homeowners notice these signs, they should immediately turn the system off and call a professional for heater repair. To help prevent overheating in the first place, homeowners can replace their HVAC air filter(s) every 1-3 months and schedule regular heating maintenance (ideally once every autumn) with a professional to help catch and resolve any issues that may lead to overheating – as well as the other issues mentioned above!
