Hitech PTAC Service Expert.

Need someone who can keep those slim PTAC units whisper-quiet and cool, even on Lexington Avenue’s busiest days? Hitech PTAC Service Expert handles a sweep of HVAC tasks, from routine repairs to quick turnarounds to make sure the air stays steady. A small outfit with an owner who identifies as veteran-, women-, Latino-, Indigenous-, disabled-, Asian-owned, they move between each call with efficient precision. If your vertical system misbehaves on the third floor—or anywhere on the Upper East Side—they’re on call and ready.

Find them a block north of 92nd Street at 1125 Lexington Ave., floor 3, New York, NY 10075. The 1 train drops riders a four-minute walk away, and the building’s lobby is keycard-controlled—call ahead to arrange access. The phone line rings straight through to their dispatcher at (646) 621-1400; leave a brief rundown of the symptoms — clunks, leaks, or no heat at all — and they’ll pencil you in for the next available slot.

Finish your instructions online before you leave the sidewalk. Drop the address into their interactive map at https://www.google.com/maps/place?ftid=0x89c259ff9db969af:0x328e4ee83aa932a3 to see the curb-side marker and the simplest route from your front door.
