Furnaces

A furnace is a machine that is used for heating. In an air conditioning system, a furnace is a major device which is permanently installed to provide heat throughout the designated interior area. Natural gas is the most commonly used fuel source for furnaces in North America.

Today, domestic furnaces are known as either condensing or non-condensing. This classification is determined by the furnace’s effectiveness in removing heat from the exhaust gases. The furnace transfers heat to the designated areas through a conduit distribution system. If this distribution is accomplished through hot water or another hot fluid or through steam, the furnace is more likely to be known as a boiler. One distinctive of having a boiler is that furnace can then supply hot water directly into the taps rather than the water being dependant upon a separate water heater. This would prove to be more cost-efficient. However, a distinct disadvantage to having this type of boiler is that if it should happen to break down, not only will you not have heat, but you will also not have hot water in your taps.

Today, most furnaces generally use a fan to distribute air to the rooms throughout the house or building. The fan also works to retract the cooler air back into the furnace so that it can be reheated and re-distributed throughout each room. This process is called forced-air heat. Once at the furnace, the cool air goes through into the furnace, generally through an air filter then the blower and then through the heat exchanger of the furnace, where it is then distributed throughout the house or building.

Furnaces are generally easy to maintain and cause very few problems. It is imperative that you keep your furnaces in optimal condition to ensure peak performance. This will be accomplished through good regular maintenance. Regardless of the make or model of your furnace, there are a few basic steps you can take to keep your heating system in peak condition.

  • Regularly clean the three main components of your furnace or heating system: the filter system, the blower and the motor.
  • Replace or thoroughly clean the furnace filter at the beginning of the heating season and then again once a month throughout periods of continuous use.

It is imperative that you always replace parts and pieces of your furnace with other parts or pieces of the same make. Using different parts can damage your furnace and cause you to have to pay exorbitant amount of repair costs. Keeping your furnace clean, especially keeping the filters clean is the single most important thing you can do to ensure maximum functionality of your furnace or heating system.
