Totally agree about ductwork quirks causing uneven temps. My house is pushing 90 years old, and when we first moved in, we had one bedroom that was always chilly—even with the vents wide open. Turns out, a section of duct had come loose and was just hanging there, blowing air into the crawlspace. Quick fix once we found it, but it took us months to figure out! Older homes definitely keep you on your toes...

Ha, been there myself. Older homes definitely have their quirks—especially when it comes to HVAC. I invest in properties, and I've seen some wild ductwork setups over the years. One place had ducts that looked like someone pieced them together from leftover scraps; no wonder the airflow was all over the place. Another time, we found a vent completely blocked off behind drywall—someone must've remodeled and just forgot about it.
Honestly though, hitting 20 years with the same HVAC is pretty impressive. Most units I've dealt with start showing their age around 15 years or so, especially if maintenance has been spotty. If yours is still running strong at two decades, that's either great luck or you've been diligent about upkeep. Either way, I'd probably start budgeting for a replacement soonish... better safe than sorry when it comes to heating and cooling.
Twenty years is pretty solid, but honestly, older HVAC systems can be real energy hogs. I remodeled a place recently that had a 22-year-old unit still chugging along, but swapping it out for a modern, efficient system cut the energy bills by almost half. Have you noticed your energy costs creeping up lately, or is it still running pretty efficiently?
Twenty years is definitely impressive, but honestly, I wouldn't rush to replace it just yet if it's still running smoothly. My parents had an HVAC system that lasted almost 25 years, and even though everyone kept telling them to upgrade for efficiency, their energy bills weren't actually that bad. When they finally did replace it, sure, the bills dropped a bit—but nowhere near half. Sometimes the savings aren't as dramatic as advertised, especially if you've been good about regular maintenance and filter changes.
I guess what I'm saying is, don't feel pressured to swap it out immediately just because it's older. If your energy costs haven't spiked noticeably and you're comfortable, you might squeeze a few more good years out of it. Every situation's different...just keep an eye on things and trust your gut.
I get your point, but honestly, waiting too long can backfire. My uncle had a similar mindset—his HVAC was pushing 22 years and still running fine, so he figured why replace it? Then one winter night, it just quit. No warning signs, nothing. He ended up paying extra for an emergency replacement and spent two freezing nights bundled up with space heaters. Sometimes it's worth swapping things out before you're forced into a rushed decision...just something to consider.
