I was working as a professional for a Dor-Mar Heating & Air Conditioning company. I was responsible for completing a job that involved installing a new heating and air conditioning system in a residential home. The job required me to work with the homeowner to determine the best system for their needs, and then to install the system according to the manufacturer's specifications. One of the challenges of this job was that the homeowner had a specific type of system in mind, but the manufacturer's specifications were not clear. I had to spend a lot of time researching the system and consulting with the manufacturer to determine the correct configuration. Once I had determined the correct configuration, I had to install the system in the home. This involved running pipes, wiring, and ductwork, as well as installing the heating and air conditioning unit itself. I had to make sure that everything was installed correctly and that the system was working properly before leaving the job site
