Talk about “Hot Town, Summer in the City!” This summer’s heat has once again brought our attention to the importance of air conditioners—and keeping them in good working order.
The New York City Department of Buildings shares some general information here.
When dealing with historic buildings and landmarks, we have the following suggestions:
- Seasonal installation of through-window units that don’t alter the window sash or frame does not require a permit.
- Window air conditioning units that require the installation of exterior brackets do require permits from the Landmarks Preservation Commission when installed at landmark buildings.
- Care should be taken to make sure exterior brackets are screwed into mortar joints instead of stone.
- Affixing a vinyl tube to the drainage hole of a window air conditioning unit can redirect water and keep it from running down masonry, which might cause staining or damage.
- The Landmarks Preservation Commission’s new Permit Guidebook provides more detailed information about various types of HVAC installation.
