My brother and I bought houses that were built in the same year, several decades ago.
The houses weren’t in the same town, but within driving distance and it wasn’t odd that they were constructed in the same year.
This area went through a big housing boom back while the two of us were in that time frame and a lot of the houses were built with the same style! Not only were our houses built while the two of us were in the same year, but our HVAC systems were replaced while the two of us were in the same year, which meant that our modern HVAC systems were the same age, but knowing this, we’ve always kept each other accountable for HVAC tune ups and we’ve always compared our energy bills to see who was able to save money, however last year though, our furnaces needed to be replaced because they were running inefficiently and experiencing a lot of concerns. I decided to have my heating system replaced at the end of the Winter time season and my brother decided to wait until the following fall; He said that he didn’t want to spend the money on the heating system when he had almost an entire year before turning it on again, however since he chose to do this, he had the lingering responsibility to pay for and replace his heating system for weeks while I was able to relax knowing that mine was handled, and by the time fall rolled around, I could sense that my brother was relieved. It would have caused much less stress and anxiety if he’d simply replaced his heating system at the end of the Winter time like I did.
