I was a professional who worked for a Dor-Mar Heating & Air Conditioning company. I was part of a team that installed a new heating and air conditioning system in a home. The job required two men to add a cap to the vent and secure it in place. The first step was to remove the old vent and clean the area. Then, we installed the new vent and secured it with screws. Finally, we tested the system to ensure it was working properly.
