I was a home service technician who was called to replace thermostats and elements in a home. The homeowner had noticed that their home was not heating up properly, and they suspected that the thermostats were the issue. I arrived at the home and began to inspect the thermostats. I found that one of the thermostats was not working properly, and it was causing the home to not heat up. I replaced the thermostat and tested it to ensure it was working properly. I also noticed that one of the elements in the furnace was not working properly, so I replaced that as well. The homeowner was very grateful for my help, and they were able to enjoy their home again.
