3 Major Problems that Result from a Faulty Heating System

If a home’s heater has been around for a while, it may start exhibiting problems that can be dangerous to the household. These problems can be more than just an inconvenience, and if a homeowner notices any of the signs, they should have it looked at by a reputable professional as soon as possible. The paragraphs below discuss three furnace or heating system hazards needing heater repair.

The Emergency of Carbon Monoxide Poisoning

Carbon monoxide is a dangerous byproduct of combustion. In a fully functional heating system, carbon monoxide or CO is contained or vented from the home. CO can leak into the home if a burner is not working properly. This substance is toxic and deadly. If the following symptoms appear in the household and are remedied by stepping outside, the heater should be turned off immediately, and a professional should be called. Some of the symptoms of CO poisoning are:

  • Disorientation
  • Drowsiness
  • Dizziness
  • Fainting
  • Headaches
  • Lightheadedness
  • Nausea
  • Vomiting

The Danger of Growing Mold

This is often the result of improper moisture drainage within the heating unit. Also, irregular or poor heating maintenance, which can leave air filters in bad shape, can contribute to this problem. Mold can spread from the furnace filter into the air ducts and then can be transported throughout the house. Homeowners should ensure they keep up with heating repair and maintenance to avoid these problems. 

The Problem of a Furnace Overheating

Overheating can cause damage to the heater, which can lead to the carbon monoxide poisoning mentioned above. It can be a problem with the thermostat or a dirty air filter. These issues would be solved by having regularly scheduled professional maintenance to check these things before the heater is turned on for the season. Some of the signs of overheating are detailed below.
  • Burning Smell: A burning smell could mean a serious problem with the furnace or heater, which can include a fire within said furnace or heater.
  • Uncomfortable Temperatures: This can be a problem if it is getting too warm in the house or the temperature is above the setting on the thermostat.
  • High Energy Bills: This can mean overheating or a loss of efficiency. Either way, there is an underlying issue that needs to be addressed.
  • Humming Noise: A humming or loud vibration can mean something is damaged and can result from overheating.
