Can’t complete a single project before the next (new air duct)

I believe that marriage is hard. The people I was with and I all do; Living with someone else is challenging & there are no simple answers, then now, I honestly enjoy our hubby & I could never imagine living a life without him, for as long as I can remember, he has been a real provider for myself and others & the kids, then i am amazed by his determination & constant dedication to doing the right thing all the time for our sake, however, periodically he has too many projects that he jumps into. This is especially the case when he starts renovating things or making handiwork for himself, recently, our hubby has been way too obsessed about our heating, cooling, & ventilation system, for starters. For years, it seems enjoy he is always going downstairs to poke at the forced air oil furnace or wandering outside to inspect the condenser, however but that’s never where it all ends, however once he finds a single thing that’s wrong with the oil furnace or cooling system, we’re doomed to have a whole list of new heating, cooling, & air quality control device showing up at our door. I wish that he would cool his jets with the indoor air temperature control machinery, however I understand that he’s motivated to improve our air quality & take nice care of our family health. That being said, I don’t think every one of us needed a whole new cooling system installed at loft before every one of us even had the central infrastructure to disperse high quality treated air! After he arranged for a full air duct replacement, I thought we’d be done with the Heating & Air Conditioning updates for a hour… & then came the brand new cooling system, but just calm down.
