If you're asking yourself that question, the answer is probably yes. Many residents hesitate to call maintenance when small problems occur, because they don't want to "make a fuss" about a relatively small issue. Unfortunately, that well-intentioned delay can cause larger problems.
A minor issue in your apartment may be tied to a more serious one you can't see. For example, that small yellow spot that's forming on your ceiling may mean that the pipes above your apartment are leaking. The discoloration may be insignificant, but the damage that's occurring behind the scenes may not be. Only a professional can make that call, and that won't happen if you don't let management know about the problem.
In some cases, you may even be responsible for additional damage that occurs because you neglected a problem that could have been remedied earlier. When in doubt, err on the side of reporting the problem and let the experts decide if a repair is necessary.
