Buying my first home was a big deal for me. I am single, twenty four years old, and earned my nursing degree all on my own. Sure, my parents offered to help but I felt that I wanted the indepence of accomplishing it as an adult. I was able to get a good paying job at a local hospital so financing my home was easy. Most of my friends are still living with their parents and struggling to pay their student loans. I feel fortunate to have made it this far at such a young age. Now, buying a home and taking care of it are totally different. For this, I depend on my parents. Not financially of course, but, for advice and knowledge on how to get things done. My dad is very handy so if I need something built or repaired he is more than willing to pitch in and help. He is also willing to teach me these skills and I find that most beneficial of all. One of the things that I learned was how to care for my HVAC system. He did recommend that I have it checked out by a professional at least once every few years, but, because my home has a boiler instead of a furnace, there is really no need to have it serviced annually. He showed my how to check for air in the supply lines too. This technique is called, “bleeding” the lines There are small valves located throughout the system that need to be loosened from time to time to make sure that there are no air bubbles trapped in them. These air bubbles don’t hurt the system but they do make it run less efficiently and can cause them to be very noisy when the system kicks on.
