The emergency services are generally good. I remember, before the revolution, there was a saying "a plumber costs is more than a king". It means to get plumber in your flat, you had to pay a high price and you had to wait a long time. I think the situation has totally changed now. I would say that service companies are almost at the same stage as the western standard. I believe you will choose the right company to help you if you need them. Good luck.
