No, and this is the one place we'll say it plainly. A torsion spring is wound under enough tension to break a hand or worse if the winding bars slip, and the tools that make it safe - the right size bars, a proper clamp - aren't things most homeowners keep in a drawer. Extension springs are lower tension but still capable of snapping toward you if the safety cable is missing or has already frayed through, which is common on older setups.
What you can safely do yourself: check whether the door is torsion or extension style (torsion is the coiled spring above the door on a shaft; extension is a stretched spring running along the horizontal track), and note whether it broke clean or is just sagging. That tells us what to load on the truck before we make the 18-mile drive out from Blue Springs, and it saves you a wasted trip if we show up with the wrong spring type.
