The Heat is On
Electric furnaces have good points and bad points. The cost of running electric resistance heat is high. It is one of the least efficient methods for heating your home. The good points are that the machine itself is easy to install and the service is less costly than other types of heating systems. There is no one part in an electric furnace that is so costly that it would break the bank like a heat pump compressor or gas furnace heat exchanger. Because they are so easily and cheaply repaired they are kept in operation for long periods of time. This leads to failures that are very common. The most common failure I find is overheated electrical terminals. This can be due to loose wiring or failing components. Here is a short electric furnace troubleshooting video detailing a couple of these common failures.
