When you need hvac maintenance in NYC, you really need hvac maintenance. Anyone who has lived in New York City during a harsh winter knows the sheer terror that washes over you when the heat goes out. You better know someone who lives nearby with a fireplace or a working heater or you are in for a miserable few days. In some cases it can take a few weeks to get someone out to assess the problem. Living in a brownstone means at some point the heat is going to go out. Sure enough, mine went out in the middle of a bad storm. So of course I immediately got online and tried to find someone who could make it through the clogged streets in order to fix the unit. My worst fear was that I would need a brand new heater.
