"Fixing those was cheaper than expected and made our old HVAC feel brand new again."
Couldn't agree more—ductwork is often overlooked, yet it's one of the simplest ways to boost efficiency. I've seen plenty of homeowners jump straight into expensive replacements without realizing their ducts were leaking conditioned air into attics or crawl spaces. A thorough sealing and insulation job can sometimes extend the life of an older HVAC by several years, not to mention significantly lowering energy bills.
One thing I'd add from experience: have you also checked your thermostat placement? I've found that relocating a poorly placed thermostat—away from direct sunlight or drafts—can noticeably improve comfort and efficiency. Curious if anyone else has noticed similar improvements just by adjusting thermostat location...
Thermostat placement is a good call, actually. Had mine in a hallway near a big window for years and never thought twice about it. Every afternoon, the sun would hit that spot directly, and the AC would kick on way more than necessary. Moved it to an interior wall away from windows and vents, and the difference was pretty noticeable—fewer cycles, more consistent temps, and lower bills.
Another thing I've noticed is how much difference ceiling fans can make. I know they're not technically part of the HVAC system, but hear me out... When I started using ceiling fans regularly, I could bump the thermostat up a couple degrees in summer without feeling uncomfortable. Same goes for winter—just reverse the fan direction, and it pushes warm air down from the ceiling. It's a small tweak, but it adds up over time.
Speaking of overlooked stuff, has anyone else experimented with landscaping or shading around their outdoor units? A friend of mine planted some shrubs strategically around his condenser (keeping proper clearance, obviously), and he swears it helped his AC run cooler and quieter. I'm tempted to try something similar next spring, but I'm curious if others have had success with that approach or if it's mostly just anecdotal...
I've heard the landscaping thing before, but honestly, I tried it a few years back and didn't notice much difference. Looked nice, sure, but performance-wise... seemed about the same. Maybe it's more noticeable in hotter climates or with older units?

Yeah, landscaping alone probably won't give you a huge jump in efficiency unless your unit was previously baking in direct sunlight all day. I've seen some cases where shading the condenser can help a bit, especially in areas with intense sun exposure, but it's usually subtle—maybe a slight drop in energy bills, nothing dramatic. The real benefit tends to be extending the lifespan of the equipment by reducing stress from overheating.
Honestly, if your HVAC is hitting the 20-year mark and still running smoothly, you're already ahead of the curve. Have you checked your ductwork lately? I've found that sealing leaks and improving insulation around ducts often makes a bigger difference in comfort and efficiency than landscaping tweaks. Curious if anyone else has noticed significant improvements after duct sealing or insulation upgrades...
We had our ducts sealed and insulated a couple years back, and honestly, it made way more difference than I expected. Before that, certain rooms were always freezing in winter and stuffy in summer—no matter how much we fiddled with the thermostat. After sealing, the temperature evened out noticeably, and the AC didn't kick on nearly as often. Landscaping around the condenser looks great, but yeah, can't say I've noticed a huge difference from that alone.
Funny thing is, I initially did the duct sealing purely for comfort reasons (I was tired of freezing toes!), but it ended up trimming down our energy bill a bit too. Not massive savings, but definitely noticeable over time. Makes me wonder if other small tweaks around the home have surprised people with unexpected benefits...
