I am not mechanically or technologically inclined in the least. I am so impressed by the handymen, designers, and engineers. In this day and age it is difficult to keep up with these intricate pieces of technology. They may as well be superheroes to me. As a result, those few technical and mechanical tasks that I can handle have me feeling extremely proud of myself. For instance, when it comes to my truck, I actually know how to change the oil in and change a flat tire. I will admit, however, that I am helpless when it comes to virtually every other tasks necessary to maintain a vehicle. There is another type of technology that I do not understand but certainly require in my life. I need my Heating and Air Conditioning system to work properly. I am amazed by how a single unit can manage year round weather conditions in a closed environment. Whoever invented such an innovation was an amazing person! I depend on a local HVAC company for service. I hire a technician to inspect my Heating and Air Conditioning unit. There is one trick that I have figured out how to do. Even though it’s simple, I get a bit of satisfaction out of changing the air filters in the air conditioner and furnace. I feel like I know what I’m doing when I replace the filters. A task doesn’t need to be complicated to provide a lot of positive benefits. Changing the air filter on the furnace and Air Conditioner is one of the most important jobs you can do to ensure that the unit continues to operate at peak capacity and efficiency.
