Use the right lubricant — and only that
White lithium grease, full stop. Not WD-40 — that's a solvent and degreaser, not a lubricant, and it will accelerate rust by removing the oil film the metal needs. Not silicone spray — it doesn't have the staying power at Texas temperatures. Not 3-in-1 oil — too light, runs off in heat. White lithium grease is $6 at any hardware store. Apply it to the spring coils, the rollers, the hinges, and the torsion shaft bearings. Do not apply it to the tracks — rollers ride in the tracks and you want grip, not slip.
Lubricate twice a year in Texas — not once
The standard advice is once a year. In a Texas garage that regularly hits 130 degrees, lubricant degrades faster than that. I tell Montgomery County homeowners to do it in spring — April, before the heat sets in — and again in October when it cools off. That keeps the protective layer fresh through the worst of summer and prevents the fall-through-winter dryness that causes steel to oxidize faster.
Keep the garage as cool as possible
Every 10 degrees you shave off the peak summer temperature extends component life — springs, opener motor, nylon rollers, everything. Insulating the garage door itself is the highest-impact single change. An insulated door with an R-value of 12 to 16 can keep the garage 20 to 30 degrees cooler in peak summer. A small ventilation fan that exchanges air in the morning before the day heats up also helps. None of this eliminates the Texas heat problem, but it moves your spring lifespan estimates meaningfully toward the better end of the range.
Check door balance once a year
Disconnect the opener by pulling the red release cord. Lift the door manually to the halfway point and let go. A properly balanced door holds in place or drifts slightly. A door that drops is telling you the spring tension is inadequate — either the spring has lost tension over time or it was never correctly sized. Catching this early means you can plan a replacement on your schedule, not the spring's. Takes two minutes and requires no tools.
Inspect the coils visually twice a year
While you're up there lubricating, look at the spring coils. You're looking for three things: a visible gap (which means it's already broken), rust pitting that has moved beyond surface discoloration, and coil sections that look compressed or uneven compared to the rest of the spring. You don't need to know exactly what you're seeing — if something looks different from the last time you looked, that's worth a phone call to describe it. A five-minute conversation can tell you whether it's nothing or something.
Don't ignore what you can't fix yourself
Spring winding and tension adjustment are not DIY jobs. The energy stored in a torsion spring under load is substantial and the consequences of a mistake are serious. Lubrication, balance checks, visual inspection — all of that you can do yourself safely. Anything that involves touching the winding cone, the set screws, or the shaft hardware: that's a call. There's no badge for doing it yourself when the risk-reward calculation is that clear.
