I was never a boy scout. I know how crucial it is to be prepared, and after just a few times being caught in the rain without an umbrella is all I needed to learn to be ready for things that can go wrong. For instance, I take our car’s repair very seriously. I follow along with the owner’s manual and do all the suggested repair. Furthermore, I keep up with our car’s oil, and I never go even one mile/day over the distance/time on the sticker. It costs me a little more upfront. In the end I know it is worth the trouble. When it comes to our HVAC system, I am just as prepared, there are so many things in the entire system that need to be tested; However, it is not just the working parts of the system. If we want to keep our whole heating and cooling system working at its best, we need to look at our apartment as well. The more insulated our apartment is and the more protected our home’s are from sunlight (in the summer), the less stress our HVAC system will be under. If our HVAC system is under less stress, of course it will work longer. A great place to beginning in insulating your apartment is in your doors and windows, and older homes that don’t have replaced weather-stripping tend to lose a lot of treated air. This means your heating and cooling system is overworking. Upgrading to energy star rated windows will also help save your HVAC system as well. The longevity of your HVAC system will also benefit from using your blinds to keep sunlight out.
