Our Review
Keep Cool NYC has earned its Best Value designation through a simple formula: fast response times, competitive pricing, and technicians who know AC systems thoroughly. Dave handles the business side with the kind of communication that reviewers notice — following up after repairs to ensure everything's working, which is a level of service that most AC companies don't bother with.
Technician Roman is the operational star, praised for expert work with window units, wall-through installations, and the custom braces and plexiglass upgrades that make NYC AC installations look professional rather than improvised. The company's turnaround during peak summer heatwaves — when every AC company in the city is slammed — draws particular praise.
Two minor issues appear in the reviews. Some customers report small gaps between units and window frames that could allow pests, which matters in NYC apartments. The company also charges a $20 fee for Certificates of Insurance, which co-op and condo buildings require before any work begins. Neither issue is dealbreaking, but they're worth knowing about when comparing quotes.
