20 years is pretty impressive—you're definitely on borrowed time, haha. But honestly, HVAC systems can surprise you. I've seen some units pushing 25+ years without major issues, usually because the homeowner stayed on top of routine maintenance. Regular filter changes, annual tune-ups, and keeping the outdoor unit clear of debris go a long way toward extending lifespan.
Still, it's smart to start budgeting for replacement sooner rather than later. Newer models are significantly more energy-efficient, quieter, and offer better humidity control. Plus, if you plan ahead rather than waiting for it to fail mid-summer (like they always seem to do), you'll have time to research options and maybe even snag an off-season discount. Either way, sounds like you've gotten your money's worth out of this one!
You're spot on about maintenance making a huge difference. My neighbor's HVAC hit 27 years before finally calling it quits, and he was meticulous about upkeep—filters changed religiously, coils cleaned every spring, the works. But even with all that care, efficiency definitely took a nosedive toward the end. He said his electric bill dropped noticeably after upgrading to a newer unit.
Speaking of upgrades, anyone here have experience with variable-speed compressors? I've heard they're quieter and handle humidity better, but I'm curious if they're worth the extra upfront cost in the long run. Seems like a nice feature, but I wonder if it's more marketing hype or actually noticeable day-to-day...

From what I've seen, variable-speed compressors do make a noticeable difference, especially in humid climates. Had one installed in a rental property last year, and the tenants mentioned how much quieter it runs and how the indoor air feels less sticky. Haven't had it long enough to fully gauge long-term savings yet, but comfort-wise, seems legit.
One thing I'm curious about though—has anyone compared the lifespan of these newer variable-speed units to traditional single-speed compressors? Wondering if the added complexity affects durability over time...
I've had a variable-speed compressor for about 4 years now, and honestly, it's been pretty solid. Definitely quieter and keeps the house feeling more comfortable overall. But I do worry about longevity—my old single-speed lasted almost 18 years without much fuss. Guess we'll see if the extra complexity means more repairs down the road...fingers crossed it doesn't drain my wallet too soon.
Variable-speed units are great for comfort, but from an investment perspective, simpler systems often pencil out better long-term. Repairs on complex tech can add up quickly...sometimes basic and reliable beats advanced and efficient.
