Have you noticed that HVAC technicians that are installing furnaces and central air conditioners in a new house always work in groups? I used to work as an electrician, and I spent a lot of my winter months installing all of the wires for these new houses.
I would spend most of my day in the company of construction workers, plumbers, and HVAC technicians. It seemed like the HVAC technicians always had the best job. They would get paid a substantial amount of money to install the central air conditioners and the furnaces, but they would only be at the houses for a fraction of the amount of time that everyone else way. HVAC technicians also always worked in groups. As an electrician, I hated that. Whenever I needed something from a different floor or room, I would have to climb down and find it myself. However, they had a whole team of qualified HVAC technicians that allowed them to get their work done easily and quickly. This also helped them carry large objects. It would take me hours to carry in all of the supplies that I needed for my electrical work, but these HVAC technicians would work together to carry in the furnaces, air conditioners, and all of their tools. Finally, they were always the most comfortable. Their HVAC companies owned all of the temporary furnaces and air conditioners, which mean that whenever they were working, they could adjust the thermostat to a comfortable temperature. I always loved working during the days that the HVAC workers were there.
