I was tasked with installing a new outside condenser for a customer. The condenser was a large unit that needed to be installed on the roof of the customer's home. I had to remove the old unit and install the new one in its place. This involved disconnecting the electrical wiring, gas lines, and refrigerant lines. I also had to make sure that the new unit was level and securely fastened to the roof. Once the new unit was installed, I had to test it to make sure it was working properly. I also cleaned up the area and removed all of the old equipment.
