Furnaces are designed to last decades without major problems so long as they are regularly maintained. However, even the best systems have problems. An indication of trouble can be your Atlanta furnace continually turning off and on in short bursts.
A furnace constantly turning on and off could often be a direct result of poor airflow through the system. Heat builds up and the detectors sense the proper temperatures have been reached and automatically shut down. In the room, the thermostat calls for more heat and starts the cycle over again.
A relay switch or control valve may also be worn and working improperly. A crack in the heat exchanger might fuel the flame to burn too hotly and cause the sensor to misinterpret the information and shut down.
These problems not only impede the distribution of heat to the living spaces, decreasing comfort, but also create intense wear on the motor and controls, threatening the very life of the appliance.
Restricted airflow can be caused most often by a dirty or clogged filter. At the furnace, there is usually a panel that can be removed to check, clean or replace the filter. It is typically a single or series of cardboard and screen panels approximately 1′ by 2′, but varies by manufacturer and furnace output.
A vacuum to pull lint free or compressor to blow it clean are the recommended tools to use a few times each year. It is a good idea to change the filters at the beginning of each heating season. The belts are also easily replaced.
The fan belts for the blower may also be worn loose and not pushing the air hard enough to get through the filters. It is a good idea to check them regularly as well.
