When your AC fails in the middle of a heatwave, the last thing you need is to waste time googling “best New York heating and AC repair” and sorting through dozens of listings. The truth? Not all HVAC companies are built the same; especially in a fast-paced market like NYC.
Below, we break down what really makes an AC unit repair service “the best”, how top NYC providers compare, and why Dezier Air continues to earn the trust of homes and businesses across the five boroughs.
What Makes a Company the Best in AC Unit Repair?
Before choosing any provider—whether it’s Dezier Air, Arista Air, or a national chain—ask these questions:
Are they licensed and insured in New York?
Do they offer emergency response or same-day service?
Are parts and labor covered under warranty?
Do they work with the brands and systems I have?
Can I trust their technicians inside my home or building?
These are the foundational criteria for identifying the best AC unit repair services—and the ones we use to assess local competition below.
Top HVAC Players in NYC: Who’s Who
Figlia & Sons
A long-time favorite in NYC’s HVAC world, Figlia & Sons is known for its rapid response times and large crew availability. They service many mid-size to large commercial properties and are recognized for their legacy service standards. However, they often don’t focus on hyper-personalized residential care.
Donnelly Mechanical
One of NYC’s most established commercial HVAC firms, Donnelly specializes in large-scale, industrial, and institutional AC work. They’re excellent for complex high-rise or data center cooling but not ideal for individual property owners seeking same-day residential repair.
AFGO Mechanical Services
AFGO brings scale, smart tech, and efficiency to the table. Their systems and dispatch tools are top-tier, but they mostly serve enterprise clients. Not your go-to if you’re a homeowner with a broken window unit or a mini-split in a brownstone.
