Yes — functional air conditioning is legally required for Southern Highlands rental property habitability. Under NRS Chapter 118A, landlords must maintain rental properties in "habitable condition" — and in Las Vegas's extreme summer heat (regularly exceeding 110 degrees), working AC is essential. AC failures in Southern Highlands rentals are emergencies requiring prompt repair response.
Even for newer Southern Highlands homes, regular HVAC service is critical — Innova Realty & Management maintains relationships with vetted local HVAC vendors, ensuring fast AC repair during peak summer demand when other landlords wait days for service.
