"Rare to find an HVAC company in NYC that provides the excellence that Airnizer provides. Very thorough — identified issues other contractors had missed for years."

"Came out quickly, very responsive over phone and email. Pricing was upfront with no surprises. Provided a COI and accepted multiple payment forms. Smooth, efficient experience."

"Sergey was the first to identify the underlying issue after two other companies missed it. Ordered parts and resolved everything same day. My go-to for annual maintenance."

"Vlad was there within 12 hours, diagnosed correctly, and the unit now blows colder air than it ever has. As a Southern man with a near-spiritual connection to AC — thank y'all."

"Technicians were professional and efficient, rates very fair. Quickly diagnosed the Mitsubishi wall unit, explained everything clearly and got it running. Highly recommend!"

"Sergei and Oleksandr found the leak with a nitrogen test and replaced the air handler. All units working before summer. Chose Airnizer based on the reviews — I'm happy I did."

"Sergey installed both HVAC and water heater in a tiny closet in two days. Very clear and straightforward, answered all questions. Very capable team."

"Communication was exceptional. Techs worked hard on two 18-year-old Mitsubishi minisplits, got them clean, recharged, and working like new. Not cheap, but a GREAT value."
