FAQ
I live in a 1950s split-level home in Hewlett. My central AC leaves the top floor bedrooms uncomfortably hot in the summer. Can I add a multi-zone ductless mini-split system, and do I need NYC landmark approval?
Adding a multi-zone ductless heat pump is an excellent solution to independently cool and heat upper-floor bedrooms without altering your main-floor ductwork. Because Hewlett is in Nassau County, you do not need NYC landmark approval. However, you will need a standard mechanical and electrical permit from the Town of Hempstead Department of Buildings to ensure the exterior condenser complies with side and rear yard property line setback requirements.
