Furnaces are a common and effective tool for heating homes with natural gas, and can even be found in the Valley of the Sun. A furnace actually works much like an air conditioner in that it uses a heat exchanger to heat the air that is already in the house. The most common fuel for a home furnace in the United States is natural gas, although other sources may be fuel oil, coal, or wood.
The key part of the furnace is the burner, where natural gas is combusted to produce heat. A motor in the furnace pulls air in from the house, through a grate in the above floor. As the air moves past the heat from the combustion of natural gas, it heats up. The warmer air is then redistributed throughout the house through a series of ducts throughout the residence.
Over time and continued usage, a number of problems can occur with furnaces. For example, the filters that direct the air from your home into the furnace get dirty quickly and need to be replaced regularly. Also, the ducts that distribute the warmed air throughout the house can come apart at the seams, allowing the warm air to escape and be lost. Unless the ducts and plenum, which is an enclosed space used for airflow, have been sealed using mastic or foil duct tape, the ductwork is likely to have a high leakage of conditioned air, possibly into unconditioned spaces. The most commonly encountered problem, which results in a cold house and high heating bills, is a dirty burner.
Some problems that may happen to your home’s furnace unit require professional care to resolve. Rainforest Plumbing & Air technicians are trained to work with both old and new furnaces.
