Dezier Air LLC

Dezier Air LLC holds a 5.0-star rating across 92 verified client reviews in New York, NY, establishing a reputation built on consistent execution and transparent communication. The company handles HVAC repairs and maintenance across multiple rental properties, serving both residential landlords and commercial clients throughout the city. Scheduling is straightforward, with technicians arriving as promised and explaining what actually requires attention versus optional upgrades.

What sets Dezier apart is their willingness to tackle multi-year problems that other contractors could not resolve. One reviewer described a situation where their property had struggled with persistent HVAC issues for years, requiring portable cooling during summer months, until Dezier properly diagnosed the root cause. The team works around tight schedules, coordinating around VIP buyouts, events, and limited access windows to ensure zero disruption to occupants.

Customer stories from the reviews highlight specific experiences that demonstrate their approach. For a DOGPOUND facility, a team member named Mikaela provided detailed updates and collaborative planning throughout a remediation project that ran from September through late October 2025. Another reviewer called at 1pm requiring same-day emergency service and received confirmation within 45 minutes, with the lead technician sending a photo and arrival updates. The crew remained on-site from 5:30pm until 3:00am to complete repairs and startup, earning compliments from the contractor and general contractor on workmanship and professionalism.
