I was called to a customer's home to install a new furnace. The customer had recently purchased the home and wanted to ensure that the furnace was in good working condition. I arrived at the house and began the installation process. I removed the old furnace and installed the new one in its place. I also made sure that the ductwork was properly connected and that the furnace was operating at the correct temperature. The customer was very pleased with the work and thanked me for my help.
