NU-Air was started in 2016 with the goal of providing exceptional client service to homes and light commercial properties throughout Mandeville, Saint Tammany Parish, and the surrounding areas in Louisiana.

A veteran of our armed forces, he was also elected to the Membership Committee for the Northshore Original BNI! Our Mandeville experts are available to help with all your HVAC needs.

    Supporting Our Armed Forces and Veterans

    At NU-Air, we are proud to say that we’re now a fully veteran-owned and operated business. As a veteran himself, our founder has deep respect for the incredible sacrifices our men and women in uniform make for our country each day. We strongly believe in supporting our local veterans and armed forces, and we value integrity and commitment. When you work with us, you will see those values in everything we do.

    A Trusted Advisor with Decades of Experience

    In over two decades of experience, our Mandeville HVAC expert has become one of the trusted advisers for both his former company as well as manufactures alike. This makes the customer experience at our company very different because instead of having to call out multiple engineers and wait extended time for manufactures to assist with calls, we are able to fix issues on the spot. Even customers with long-standing issues rave about the different level of support we are able to give them.

    The Foremost Company for 24 Hour Heating and Cooling Repair

    Though NU-Air is young, our experts have worked hundreds of residential and commercial jobs. From homes to universities, morgues, apartment complexes, and city, state, and government buildings, we’ve seen the gambit of types of equipment.
