Two symptoms end the conversation about adjustment before it starts. A closer body weeping hydraulic oil at the base has a failed internal seal, and no valve on top of that body will ever fix a seal that's already gone. An arm that's been bent — usually by a hand truck, a delivery cart, or a door forced open past its intended swing — has metal that's deformed past the point spring tension and valve settings can compensate for. Both are replacement calls, not tuning calls, and the difference matters because tuning a closer that's actually failed just wastes a visit confirming what was already obvious at the door.
Call (407) 792-1378The good news is that replacement is fast and doesn't mean matching the exact same part. A closer is sized to the door it's controlling — its width, its weight, and how exposed it is to wind — and getting that sizing right the first time matters more than which brand name is stamped on the cover.
A door closer is a hydraulic piston: closing spring tension pushes the arm, and internal fluid metered through the valve ports controls how fast that push happens. Once the seal around that piston degrades, fluid escapes past it instead of doing its job, and the closer loses its ability to control speed at all — the door either swings unchecked or barely moves, and no amount of valve adjustment restores pressure a leaking seal keeps letting out. A closer in this state is functionally done.
The arm assembly connecting the closer body to the door frame is engineered to a specific geometry, and once it's been bent — caught by equipment, yanked past its stop, or hit by a door propped too far open — that geometry is compromised permanently. A bent arm changes leverage and travel in ways that make the door behave unpredictably regardless of how the valves are set, and straightening it back by hand rarely restores the original tolerances even when it looks close afterward. Replacing the arm, or the full closer if the body was stressed in the same event, is the only fix that actually holds.
Commercial closers are rated on a numbered scale tied to door width and weight — a lightweight interior door and a heavy exterior storefront entrance need different spring power to close reliably without slamming or stalling. Undersizing a closer means it can't fully close a heavy door against wind or a slight incline in the threshold; oversizing makes an otherwise light door difficult for some people to push open at all. Getting this number right starts with actual door width and an honest read on the door's weight and exposure, not a like-for-like swap of whatever was there before, especially if the original closer was undersized from the day it was installed.
A barrier-free, or ADA-compliant, closer is built and adjusted to lower opening force limits so the door can be pushed open by someone with limited strength, while still meeting closing requirements for security and fire separation. That's a different unit and a different valve range than a standard-duty closer built for a heavier commercial door where opening force isn't restricted the same way. A door that sees wheelchair traffic, a medical office, or any entrance where accessibility compliance applies needs the barrier-free spec specifically, not a standard closer turned down as far as its spring will allow.
Replacement closers mount in one of a few configurations — regular arm on the pull side, top jamb mount, or parallel arm on the push side — and the frame, the door swing direction, and any adjacent hardware like a panic bar determine which one actually fits. A parallel-arm closer sits closer to the frame and clears certain trim conditions a regular-arm unit can't, while a top-jamb mount is often the only option on a narrow-stile aluminum door where there's no room for anything else. Matching this correctly the first time avoids a second visit for a unit that physically doesn't clear the opening.
An oil leak or a bent arm isn't a tuning problem, and treating it like one just delays the real fix. Call (407) 792-1378 to get a replacement closer sized to the actual door, not swapped in as a guess.

By the door's actual width and an honest assessment of its weight and wind exposure, matched to a closer's rated size range, not by assuming the old unit was sized correctly to begin with.
It's a different spec built for lower opening force, and cost depends on the specific unit and mounting — it's discussed at the door once the requirement is confirmed.
