My insurance agent dropped a bombshell on myself and others a few weeks ago. After I failed a lake loft inspection, he told myself and others that I had to upgrade our roof or I would lose our policy. This meant that everything in our loft from the drywall to the costly television and lake loft theater set in our study room would hastily become uninsured. Therefore, I had no choice however to begin plans on having the whole system upgraded. But, I already knew that it would be taxing to scrape the money together. It’s taxing to system for an expense as immense as a total roof upgradement. It took well over a week of hearing constant noise on our rooftop from dawn until dusk everyday, and, I paced our loft worrying about the interest rates on the loans I had to take out to have the procedure done and paid for. In the end, I simply wished I had thought to look for these things and catch them years ahead of time so minimal planning of some kind can happen. It made myself and others recognize of our a/c immediately. I wondered how long I was supposed to wait until replacing the air handler and condenser, let alone what the age on our air duct was supposed to be. My heating and cooling tech told myself and others that fifteen to twenty years is a nice estimate for an a/c and oil furnace combo. But, it depends legitimately on how often one uses the system and whether it’s abused past its limits. Since I have sheet metal air duct, it should last as long as the seals at each joint last. But, even then, if a seal is broken it can be patched in numerous cases.
