According to RedBeacon, the most common central heating problems include gas supply problems, blocked or leaky ducts, weak pilot lights and malfunctioning thermostats. Gas supply problems are the responsibility of the utility company, but the financial responsibility of other problems rests on the owner.Continue Reading
Many malfunctioning central heating systems have blocked or leaky ducts. If the problem is a blockage, dead animals and bird nests are often to blame. Blockages prevent proper air circulation and require professional attention unless the clog is visible at the duct's mouth. Leaking ducts always require professional diagnosis and repair. Patching fixes minor leaks, but replacement is the only option for those with serious holes or other extensive damage.
A weak or inconsistent pilot light is a symptom of a potentially dangerous problem. Without a strong, steady pilot light, a furnace is inefficient and unreliable. This increases the risk of lethal carbon monoxide accumulating in the home. The Automobile Association explains that carbon monoxide is invisible and has no odor. Battery-operated carbon monoxide detectors are essential safety equipment in modern homes. Properly functioning pilot lights burn a vibrant blue. If the pilot light flickers or turns yellow, do not wait for the carbon monoxide alarms to sound; seek professional help immediately.Learn more about Heating & Cooling
The most essential factors affecting fuel costs, particularly gas and oil, are local competition, supply of the heating source, provider operating costs and the season itself. Costs are also subject to market fluctuations among competing heat sources. For instance, demand for coal or gas may rise when oil prices spike.Full Answer >
Honeywell sells thermostats that work with almost all types of popular central heating systems, although homeowners using obscure types of heating systems might need special-made thermostats, often from the manufacturer. They also have thermostats for heat pumps, which require extra features.Full Answer >
To troubleshoot problems with a gas furnace's pilot light, it is important to check the pilot light mechanism and flame as well as the gas supply and the condition of important parts, such as the thermocouple. This covers all the elements potentially related to this type of malfunction.Full Answer >
Gas ovens installed on ranges have thermostats to stop heating when needed, and systems that use pilot lights have thermocouplers that shut off gas if the pilot light goes out. Newer gas ranges typically have several thermal fuses that stop gas if high levels of heat are detected.Full Answer >
