The term furnace refers to a natural gas powered heating systems. The gas furnace heating system goes into action when the thermostat tells it that the room temperature has dropped below your preset comfort level. The thermostat sends a low-voltage electrical signal to a relay in the furnace, which signals a valve to open and deliver natural gas to the burners and for the blower to turn on. The furnace’s pilot light or electronic ignition lights the burner inside the combustion chamber. This creates heat in the furnace’s heat exchanger, a metal chamber around which the moving air flows.
Once warmed, the air is pushed into the hot-air plenum and then out to the rooms through duct work. The combustion gases created by burning fuel are vented through a flue in the roof or, with high-efficiency furnaces, through a wall. One of the benefits of a forced-air system is that it can receive a whole-house air-conditioning unit, a humidifier, and an electronic air filter—all of which can take advantage of the furnace’s air handler and ducts for delivery of conditioned air to rooms.
Duct work is generally metal wrapped with insulation or a flexible plastic-wrapped insulated material that helps retain heat. Carbon monoxide is a dangerous, odorless gas that is produced as a byproduct of natural gas combustion. If your unit uses propane or natural gas, it is highly recommended that your home utilizes a carbon monoxide detector to keep your family and friends safe. It is also important to provide sufficient ventilation to the furnace. Items set too close to the furnace could present a fire hazard.

The concept of a heat pump is generally the same as an air conditioner. When a heat pump is used for heating, it employs the same basic refrigeration cycle used by an air conditioner, but in the opposite direction. The refrigeration that travels from the outside condenser to the inside evaporator coil gaines latent heat at the evaporator coil. The blower then blows across the evaporator coil to produce radiant heat inside your home.
When the temperature gets really cold outside the air handler will utilize auxiliary electric heat strips as a secondary method to warm the air and the home. Heat pumps are also a popular option in the south due to the milder winters and for areas that do not have natural gas readily available. Heat pumps also work extremely efficient, because they simply transfer heat, rather than burn fuel to create it.
