Funny you mention the 20-year mark—I had a client whose HVAC was pushing 25 years, and when we finally replaced it, I swear the old unit looked like something from a museum. They joked it was held together by dust and stubbornness at that point. But seriously, newer units really do make a difference in comfort and bills. Luck helps, but regular TLC is key...and maybe a little duct tape here and there doesn't hurt either.
Haha, duct tape really is the unsung hero of home maintenance...I swear I've seen entire appliances held together with just tape and hope. But seriously, 25 years is impressive. Makes me wonder though—at what point do you think it's better to bite the bullet and replace rather than keep patching things up? I had a homeowner recently who kept insisting their ancient system was "just fine," but when we finally swapped it out, they couldn't believe how quiet and efficient the new one was. They joked that now they missed the old rattling noise because it helped them fall asleep at night. Ever had anyone actually regret upgrading their HVAC?
"Ever had anyone actually regret upgrading their HVAC?"
Funny you mention that—I haven't seen outright regret, but I've definitely heard a few people say they miss the familiar quirks of their old systems. From a technical standpoint though, once you're past the 15-20 year mark, efficiency losses and repair costs usually outweigh sentimental value. I'm curious, has anyone here done a detailed cost-benefit analysis comparing ongoing repairs versus replacement? Might be interesting to see actual numbers behind these decisions...
Interesting point about the sentimental quirks—I totally get that. My house is pushing 100 years old, and when we swapped out our ancient furnace, I actually missed the weird rattling noise it made every time it kicked on. Felt oddly comforting, you know? But honestly, I think the cost-benefit analysis can be a bit misleading sometimes. Sure, newer systems are more efficient on paper, but the upfront cost is pretty steep. Plus, older homes like mine often need extra work to accommodate modern HVAC setups—ductwork, electrical updates, insulation tweaks... it adds up fast.
I ended up doing a partial upgrade—kept some of the original ducting and just replaced the main unit. Saved money, kept some of the charm, and still got better efficiency. Not saying it's the perfect solution for everyone, but sometimes a full replacement isn't always the clear-cut winner people assume it is.

Did something similar myself. Full replacements always sound great until you see the bill... Partial upgrades can be a solid compromise, especially if your existing ductwork is still decent.
