Heaters can make the difference between feeling miserable and comfortable in a house, especially on freezing cold days. Some people are fine with obtaining warmth from a space heater when they need it, but it can take a long time to heat up even a single room. There are also people who solely rely on central heating systems to obtain the warmth that they desire, and there are many reasons why it is so. A common reason is due to central systems not taking long to reach high temperatures, even when warming an entire house up. However, when a furnace to a central system has problems, it can mean that a homeowner is unable to obtain heat until the problem has been fixed.
A Blown Fuse or Tripped Breaker
Losing power is something that sometimes happens to central heating systems, but the problem isn't always major. For example, bringing the power back might only require a flip of a circuit breaker that is off. If the breaker isn't off, you might actually have a more serious problem, such as the need for a technician to repair the breaker. A blown fuse is another problem that might lead to a central heating system losing power. The area where the fuse is located is directly on the furnace and can easily be accessed by an HVAC technician. He or she can simply replace it with a new one.
Gas Problems and the Pilot Light
A blown-out pilot light can cause a central heating system to stop distributing heat, as it is unable to produce any. Gas furnaces are usually equipped with pilot lights and they must be ignited when a heater is on, which usually happens automatically. If the pilot light doesn't automatically ignite, it might be due to the orifice being dirty or because it is in need of being manually ignited. Sometimes a pilot light is unable to automatically ignite when the heater is one due to a gas problem. For example, there might be little to no gas flowing through the line that the furnace obtains it from.
The Blower Fan Isn't Powerful
A blower fan that is weak can make obtaining heat difficult, even if the furnace is in top shape. The furnace might be responsible for heat production, but the blower fan is the part that is responsible for making air. A weak fan might need to be repaired or replaced depending on what the problem is. It is possible that the fan only needs a more powerful motor.
